PGP is built upon a Distributed Web of Trust in which the trustworthiness of a user is established by others who can vouch through a digital signature for that particular identity. Preventing its wholesale adoption are a number of inherent weaknesses to include (but not limited to) the following: 1) Trust Relationships are built on a subjective honor system, 2) Only first degree relationships can be fully trusted, 3) Levels of trust are difficult to quantify with actual values, and 4) Issues with the Web of Trust itself (Certification and Endorsement). Although the security that PGP provides is proven to be reliable, it has largely failed to garner large scale adoption. In this paper, we propose several novel contributions to address the aforementioned issues with PGP and associated Web of Trust. To address the subjectivity of the Web of Trust, we provide a new certificate format based on Bitcoin which allows a user to verify a PGP certificate using Bitcoin identity-verification transactions - forming first degree trust relationships that are tied to actual values (i.e., number of Bitcoins transferred during transaction). Secondly, we present the design of a novel Distributed PGP key server that leverages the Bitcoin transaction blockchain to store and retrieve Bitcoin-Based PGP certificates. Lastly, we provide a web prototype application that demonstrates several of these capabilities in an actual environment.
In this paper, I propose a new concept for understanding the role of algorithms in daily life: algorithmic authority. Algorithmic authority is the legitimate power of algorithms to direct human action and to impact which information is considered true. I use this concept to examine the culture of users of Bitcoin, a crypto-currency and payment platform. Through Bitcoin, I explore what it means to trust in algorithmic authority. My study of the Bitcoin community utilizes interview and survey data. I found that Bitcoin users prefer algorithmic authority to the authority of conventional institutions which they see as untrustworthy. However, I argue that Bitcoin users do not have blind faith in algorithms; rather, they acknowledge the need for mediating algorithmic authority with human judgment. I examine the tension between members of the Bitcoin community who would prefer to integrate Bitcoin with existing institutions and those who would prefer to resist integration.

Electronic voting provides accuracy and efficiency to the electoral processes. World democracies would benefit from a secure e-voting system not only to improve voter participation and trust but also to prevent electoral fraud. However, current e-voting systems are complex and have security weaknesses. In this paper, we describe a secure e-voting system for national and local elections (S-Vote). This system satisfies the important requirements of an e-voting system through state-of-the-art technologies and secure processes. S-Vote relies on homomorphic cryptography, zero-knowledge proofs, biometrics, smartcards, open-source software, and secure computers for securely and efficiently implementing the system processes over the various stages of the electoral process, without relying on online network connections. We outline the main conclusions of the pilot implementations of S-Vote that tested the main technologies and processes used. We also explain how the used technologies and processes achieve the system requirement. In conclusion, we recommend adopting S-Vote for its security, flexibility, economic, and scalability features.
Door het internet kan de burger rechtstreeks contact krijgen met zijn publiek zonder hulp van derden als omroepen, kranten, uitgevers, muziekindustrie, etc. Bij al deze communicaties is prominent (Youtube) of minder prominent (Wordpress) een derde partij betrokken die de communicatie faciliteert. Deze derde ontbreekt bij Bitcoin. Je kunt snel, betrouwbaar, met iedereen waar ook ter wereld bitcoins uitwisselen. Dus geen exorbitante bonussen, hoge transactiekosten, of ander ingrijpen of sturing van bovenaf. Internet in de meeste zuivere vorm: technologie van eindgebruiker naar eindgebruiker, zonder tussenkomst van derden.
This paper introduces a new information technology: ma3tch (autonomous anonymous analysis). Ma3tch enables virtual information integration to build a `dynamic networked collective intelligence' without infringing upon security, confidentiality, privacy and/or data protection regulations. It provides organizations with information and knowledge advantages. The ma3tch technology is empowered by a decentralized information oriented architecture: a `privacy by design' framework that uses distributed agents to facilitate decentralized but integrated information access, processing and analysis. It shapes a `virtual information cloud' between autonomous organizations that enables secure, integral and intelligent real time information analysis. Relevant information and knowledge distributed between autonomous organizations is automatically detected and applied throughout the network as soon as it emerges. The dynamic design principles allow practically any type of (cross domain) information to be virtually integrated: government, commercial, intelligence, law enforcement, financial, telecom, biomedical, compliance, etc., without infringing privacy, confidentiality, security or data protection rules and regulations. It advances both privacy AND knowledge beyond conventional limitations.
Online advertising is at the core of todayâs Web: it is the main business model, generating large annual revenues expressed in tens of billions of dollars that sponsor most of the online content and services. Online advertising consists of delivering marketing messages, embedded into Web content, to a targeted audience. In this model, entities attract Web traffic by offering the content and services for free and charge advertisers for including advertisements in this traffic (i.e., advertisers pay for usersâ attention and interests). Online advertising is a very successful form of advertising as it allows for advertisements (ads) to be targeted to individual usersâ interests; especially when advertisements are served on usersâ mobile devices, as ads can be targeted to usersâ locations and the corresponding context. However, online advertising also introduces a number of problems. Given the high ad revenue at stake, fraudsters have economic incentives to exploit the ad system and generate profit from it. Unfortunately, to achieve this goal, they often compromise usersâ online security (e.g., via malware, phishing, etc.). For the purpose of maximizing the revenue by matching ads to usersâ interests, a number of techniques are deployed, aimed at tracking and profiling usersâ digital footprints, i.e., their behavior in the digital world. These techniques introduce new threats to usersâ privacy. Consequently, some users adopt ad-avoidance tools that prevent the download of advertisements and partially thwart user profiling. Such user behavior, as well as exploits of ad systems, have economic implications as they undermine the online advertising business model. Meddling with advertising revenue disrupts the current economic model of the Web, the consequences of which are unclear. Given that todayâs Web model relies on online advertising revenue in order for users to have access and consume content and services for âfreeâ, coupled with the fact that there are many threats that could jeopardize this model, in this thesis we address the security, privacy and economic issues stemming from this fundamental element of the Web. In the first part of the thesis, we investigate the vulnerabilities of online advertising systems. We identify how an adversary can exploit the ad system to generate profit for itself, notably by performing inflight modification of ad traffic. We provide a proof-of-concept implementation of the identified threat on Wi-Fi routers. We propose a collaborative approach for securing online advertising and Web browsing against such threats. By investigating how a certificate-based authentication is deployed in practice, we assess the potential of relying on certificate-based authentication as a building block of a solution to protect the ad revenue. We propose a multidisciplinary approach for improving the current state of certificate-based authentication on the Web. In the second part of the thesis, we study the economics of ad systemsâ exploits and certain potential countermeasures. We evaluate the potential of different solutions aimed at protecting ad revenue being implemented by the stakeholders (e.g., Internet Service Providers or ad networks) and the conditions under which this is likely to happen. We also study the economic ramifications of ad-avoidance technologies on the monetization of online content. We use game-theory to model the strategic behavior of involved entities and their interactions. In the third part of the thesis, we focus on privacy implications of online advertising. We identify a novel threat to usersâ location privacy that enables service providers to geolocate users with high accuracy, which is needed to serve location-targeted ads for local businesses. We draw attention to the large scale of the threat and the potential impact on usersâ location privacy.
The increasing trend of embedding positioning capabilities (e.g., GPS) in mobile devices facilitates the widespread use of Location Based Services. For such applications to succeed, privacy and confidentiality are key issues. Over all privacy will have to be managed through a combination of technology, legislation, corporate policy, and social norms. There are many data privacy schemes including Zero Knowledge Proof (ZKP) those can be used for location privacy. ZKP is also useful for removing the bottleneck problem introduced by use of trusted third party. In the earlier work, authors proposed the concept of middleware architecture in which, request and response are not routed through middleware for every transaction. This has reduced the dependency on middleware. This paper presents correspondence between the authentication techniques used in above said architecture and zero knowledge proof technique. Use of the concept of zero knowledge proof for authentication and authorization in the domain of location based services is also explored.
Abstract. Bitcoin is quickly emerging as a popular digital payment system. However, in spite of its reliance on pseudonyms, Bitcoin raises a number of privacy concerns due to the fact that all of the transactions that take place are publicly announced in the system. In this paper, we investigate the privacy guarantees of Bitcoin in the setting where Bitcoin is used as a primary currency for the daily transactions of individuals. More specifically, we evaluate the privacy that is provided by Bitcoin (i) by analyzing the genuine Bitcoin system and (ii) through a simulator that faithfully mimics the operation of Bitcoin in the context where Bitcoin is used for all transactions within a university. In this setting, our results show that the profiles of almost 40 % of the users can be, to a large extent, recovered even when users adopt privacy measures recommended by Bitcoin. To the best of our knowledge, this is the first work that comprehensively analyzes, and evaluates the privacy implications of Bitcoin. As a by-product, we have designed and implemented the first simulator of Bitcoin; our simulator can be used to model the interaction between Bitcoin users in generic settings. 1
Anonymity in Bitcoin, a peer-to-peer electronic currency system, is a complicated issue. Within the system, users are identified by public-keys only. An attacker wishing to de-anonymize its users will attempt to construct the one-to-many mapping between users and public-keys and associate information external to the system with the users. Bitcoin tries to prevent this attack by storing the mapping of a user to his or her public-keys on that user's node only and by allowing each user to generate as many public-keys as required. In this chapter we consider the topological structure of two networks derived from Bitcoin's public transaction history. We show that the two networks have a non-trivial topological structure, provide complementary views of the Bitcoin system and have implications for anonymity. We combine these structures with external information and techniques such as context discovery and flow analysis to investigate an alleged theft of Bitcoins, which, at the time of the theft, had a market value of approximately half a million U.S. dollars.
Abstract. Recent results show that the current implementation of He-lios, a practical e-voting protocol, does not ensure independence of the cast votes, and demonstrate the impact of this lack of independence on vote privacy. Some simple fixes seem to be available and security of the revised scheme has been studied with respect to symbolic models. In this paper we study the security of Helios using computational models. Our first contribution is a model for the property known as ballot privacy that generalizes and extends several existing ones. Using this model, we investigate an abstract voting scheme (of which the revised Helios is an instantiation) built from an arbitrary encryp-tion scheme with certain functional properties. We prove, generically, that whenever this encryption scheme falls in the class of voting-friendly schemes that we define, the resulting voting scheme provably satisfies ballot privacy. We explain how our general result yields cryptographic security guaran-tees for the revised version of Helios (albeit from non-standard assump-tions). Furthermore, we show (by giving two distinct constructions) that it is possible to construct voting-friendly encryption, and therefore voting schemes, using only standard cryptographic tools. We detail an instan-tiation based on ElGamal encryption and Fiat-Shamir non-interactive zero-knowledge proofs that closely resembles Helios and which provably satisfies ballot privacy. 1
Recently we have observed a growing demand for secure technologies for e-commerce that do not put customers at risk of identity theft. We have also experienced the advent of Web 2.0 which has led to new business models and which has changed the way users interact with the Web. This thesis proposes a set of strategies and enhancements towards providing improved security and privacy in such new settings. We introduce a novel concept: Fair Rights Management (FRM). It can be classified as a usage control solution. FRM enables a flexible way of managing digital content. There was a need to provide additional security extensions to keep such a flexible model applicable. Thus, in our approach we take advantage of trust obtained from social networks. This is also the reason why we created an efficient zero-knowledge proof protocol that is lightweight enough to be deployed within existing web-applications. The proposed protocol is also successfully integrated with Semantic Web architecture and associated components. It enables practical Web and mobile applications which employ trust-based transactions as part of their workflow. This core contribution overcomes various disadvantages of prior art and enables a range of new applications and potentially new business models. We show that compared to existing Usage Control Models (UCON) (i) FRM is a step towards fair use in the digital world and we also argue that our approach is enforced by law; (ii) the participants of the proposed solution do not put their privacy at risk. Our research shows that existing infrastructure is sufficient to support ZKP-based solutions; and thus, it is feasible to offer the users enhanced privacy within existing deployed solutions.

This paper proposes a new electronic voting (e-voting) scheme that fulfills all the security requirements of e-voting i.e. privacy, accuracy, universal verifiability, fairness, receipt-freeness, incoercibility, dispute-freeness, robustness, practicality and scalability; usually some of which are found to be traded. When compared with other existing schemes, this scheme requires much more simple computations and weaker assumptions about trustworthiness of individual election authorities. The key mechanism is the one that uses confirmation numbers involved in individual votes to make votes verifiable while disabling all entities including voters themselves to know the linkages between voters and their votes. Many existing e-voting schemes extensively deploy zero-knowledge proof (ZKP) to achieve verifiability. However, ZKP is expensive and complicated. The confirmation numbers attain the verifiability requirement in a much more simple and intuitive way, then the scheme becomes scalable and practical.

In this paper we have formulated an online voting framework which ensures that the voter is able to vote in a public environment without his vote being eavesdropped on by a neighbor i.e. his vote becomes known to his neighbor or a third party when he marks his choice on a particular candidate. We also give a model for secure online voting system using zero knowledge proof and other cryptographic schemes encompassing the voting process of the user and the backend process of servers and the tallying and display of results and verification by the user of the vote cast by him at a later stage.
The voting plays important roles in a democratic country. Due to the problems of the existed voting m ethod, the new voting methods, electronic voting system, have been developing using the computer net work and cryptographic techniques. Many electronic voting schemes have been introduced for secure electronic voting systems. In this paper, we propose the secure electronic voting for absentee e-voting system. The absentee voting plays the important percentage in the existing voting system. But, the abs entee vote can not look forward to the security because of transmit by mail. The absentee does not kno w whether oneâs voting is exactly counted or not. In this paper, we propose the absentee e-voting syste m based on security, completeness and verifiability. We use r-th residue cryptography for homomorphi c encryption, ZKIP (Zero-Knowledge interactive proofs), RSA algorithm. Also, we propose the ne w method of tallying for multi-candidate. The goals of out voting system are the absentee vot ing based on privacy, universal verifiability, reuseability and multi-candidate.
Smart contracts combine protocols with user interfaces to formalize and secure relationships over computer networks. Objectives and principles for the design of these systems are derived from legal principles, economic theory, and theories of reliable and secure protocols. Similarities and differences between smart contracts and traditional business procedures based on written contracts, controls, and static forms are discussed. By using cryptographic and other security mechanisms, we can secure many algorithmically specifiable relationships from breach by principals, and from eavesdropping or malicious interference by third parties, up to considerations of time, user interface, and completeness of the algorithmic specification. This article discusses protocols with application in important contracting areas, including credit, content rights management, payment systems, and contracts with bearer.
Zero knowledge protocols provide a way of proving that a statement is true without revealing anything other than the correctness of the claim. Zero knowledge protocols have practical applications in cryptography and are used in many applications. While some applications only exist on a specification level, a direction of research has produced real-world applications. Zero knowledge protocols, also referred to as zero knowledge proofs, are a type of protocol in which one party, called the prover, tries to convince the other party, called the verifier, that a given statement is true. Sometimes the statement is that the prover possesses a particular piece of information. This is a special case of zero knowledge protocol called a zero-knowledge proof of knowledge. Formally, a zero-knowledge proof is a type of interactive proof.

The moving image archive of the US Agency for International Development (USAID) includes a copy of the film The Double Day (1975), cataloged in the series Moving Images Relating to International Development Programs and Activities, 1979â1991, a collection of more than eight hundred titles âcreated to provide information on assistance programs supported by the Agency for International Development (AID).â1 Yet, The Double Day does not, in fact, directly depict or engage with any specific development or aid initiative. Instead, the filmâdirected by US-based Brazilian filmmaker Helena Solberg as part of the International Womenâs Film Project collective and described as âthe first Latin American feminist documentaryââexamines the gendered dynamics of paid and unpaid labor through the testimonies of women from Argentina, Bolivia, Venezuela, and Mexico.2 Its presence in the USAID archive is likely a consequence of its funding history, having received support from the Inter-American Foundation, a USAID-affiliated entity; the development agencies of Denmark, Norway, and Sweden; the United Nations Development Program; and US philanthropist Calvin Cafritz.3These transnational funding structures not only enabled the filmâs production but also determined its archival destination, which renders legible its place within the history of international development.4 The Double Dayâs institutional trajectory reflects the shifting configurations of aid, gender, and media during a historic moment when women were being repositioned at the center of what Arturo Escobar has described as developmentâs âregimes of visuality.â5 Especially relevant to The Double Dayâs production and exhibition was the international institutional framework of Women in Development (WID). Emerging in the early 1970s and culminating in United Nationsâ proclamation of 1975 as International Womenâs Year, WID emphasized womenâs participation in the global economy as both an index and mechanism of development. Indeed, The Double Day premiered at the World Conference of the International Womenâs Year, held in Mexico City.6 Within this context, the film forms part of a broader trajectory of media use by international organizations that intensified during the 1970sâas best exemplified by Media Habitat, a collection of 236 documentary films commissioned by the United Nations to represent urban and rural development initiatives for the 1976 Habitat Conference on Human Settlements in Vancouver. As a policy-shaping initiative, Media Habitat primarily featured films from the Global South intended not only to illustrate but also to help codify standardized audiovisual markers of âunderdevelopmentâ that determined access to the emerging global economic order and to international aid.7Framed in relation to these international institutions and their operations, The Double Day could similarly be considered âdevelopment mediaââexemplifying the type of nonfiction media produced and distributed outside of the commercial film circuits whose aspects and subcategories have been variously described in scholarship as nontheatrical, useful, sponsored, institutional, industrial, educational, or nonprofessional/amateur.8 Scholars working in this area have emphasized the institutional contexts of such mediaâs production and exhibition infrastructures as shaping its instrumentalized effects. From a feminist perspective, such an approach is crucial to grappling with the broader question of how âgender impacts [these worksâ] shape, content, and trajectories.â9 Yet we also argue that, taken in isolation, the institutional and infrastructural contexts are insufficient to account for the complex relationship between media and development, potentially not only limiting our understanding of the reach and impact of development but also distorting our interpretive conclusions. For example, to categorize The Double Day as âdevelopment mediaâ is to overlook the filmâs place within Solbergâs directorial oeuvre, as well as within the histories of both transnational womenâs filmmaking and radical Latin American documentary cinema to which it simultaneously belongs. Such exclusive framing is especially limiting given that women globally were disproportionately engaged in nonfiction production throughout the twentieth centuryâsometimes by political choice but more often due to structural exclusions from fiction filmmaking. Even in nonfiction historiography, however, institutional media has remained particularly marginal, reinforcing hierarchies that separate such works from the aesthetic and authorial frameworks through which film history has been constructed.10 This marginalization not only tends to erase womenâs contributions but also presumes a âweakâ or derivative authorship, rendering these films unworthy of the interpretive attention needed to apprehend their aesthetic and political complexity.11 The same dynamic is likely to structure assumptions about âdevelopment mediaâ as well.Categorizing The Double Day exclusively within this category would further prompt us to assume top-down institutional analyses that have been characteristic of both institutional media methodologies and the scholarship on development at large. This, in turn, would risk obscuring this filmâs radical Marxist approach to womenâs labor as well as its concrete contribution to activism and its attendant grassroot structures. In Mexico City, The Double Day became a catalyst for feminist solidarity in practice when one of the filmâs protagonists, Bolivian activist and trade unionist Domitila Barrios de Chungara, was invited to participate in the Tribune of Non-Governmental Organizations held alongside the official UN conference.12 There, Barrios de Chungara challenged Western feminist priorities by reframing the debate around labor, class, and imperialism, helping to articulate a shared Third World feminist agenda that significantly departed from the developmentalist vision of the United Nations and USAID.13 Seen through the lens of activist media, The Double Day helped forge transnational solidarity networks by enabling information exchange across the diverse voices that shaped its makingâfrom the women featured in the film to the activists who circulated itârevealing a considerably more dynamic interplay between institutional and grassroots or contingent media practices.Moreover, the filmâs Latin American contextâreflected in Solbergâs formation in Brazil as the only woman in Cinema Novo, its focus on women from across the region, and its premiere and key reception in Mexico Cityârequires grappling with the regional specificities of the very notion of development in its multiple iterations.14 Far from being an epistemological and political framework imposed solely by the Global North, both the practices of development and the theoretical foundations of developmentalism (understood as a broad and polysemic set of discourses) were shaped through the active participation of Latin American economists.15 Within this iteration, underdevelopment, as a constitutive notion of developmentalism, became central to a distinctly critical strand, which by the late 1960s became known as the dependency theory.16 This same approach is reflected in some of the best-known Latin American radical film manifestos of the time, arising precisely from the same milieus to which Solberg belonged.17These various considerations of the filmâs history illustrate the methodological challenges confronting feminist scholars seeking to assess the impact of development on media projects, theories, and practices. To disregard the developmentalist context of such works by emphasizing their political aesthetics and affects risks reproducing a romanticized narrative of heroic resistance (albeit from a feminist perspective). Yet to engage exclusively with their institutional and material infrastructures risks naturalizing developmentalismâs political and epistemological foundations at the expense of the goals and beliefs of the many women who participated in these projects. The contradictions and ambivalences that animate such histories call for feminist frameworks capable of holding both institutional complicity and radical possibility in view.This challenge resonates with ongoing debates about the politics of the archive and what Allyson Field has termed âthe practice of informed speculation.â18 As she reminds us, feminist, queer, and decolonial methodologies have long taught us to âpress at the limitsâ of the archive to âinoculate our scholarship against our evidenceâs afflictions.â19 The concern that the evidence we draw on in our analysis reproduces the very structures and blind spots of the dominant ideology and therefore shapes and delimits our interpretation becomes particularly urgent when engaging the developmentalist media corpus. Informed speculation offers an alternative by inviting the experimental, creative, and speculative rewriting of history, mobilizing the archive âin a project that runs counter to the original purpose, or the imperative to preserve, or the conditions that led to erasure.â20 Yet, as Field cautions, such speculative gestures must remain grounded in a deep and âintimate familiarity with the archiveâ that we are working with and against. Building on this imperative, we suggest that the developmentalist archive, in particular, demands expansion and critical reconsideration in ways that unsettle the very disciplinary frameworks through which it has been studied as well as the larger institutional contexts for such knowledge production.Our focus on The Double Day in the opening of this introduction thus foregrounds the entanglements of institutional and grassroots forces, local and international contexts, structural and interpersonal relations, and creative and economic factors that have shaped not only this film but the broader ecosystem of development media projectsâand their preservationâover time. Addressing such a constellation involves transgressing methodologically entrenched divisions between political economy and aesthetics, between material infrastructures and affective regimes; reckoning with divergent periodizations across film history and world economics; and situating these within the local specificities of womenâs movements and international institutional programs. It also demands attentiveness to the coexistence of multiple, and sometimes competing, understandings of developmentâeach historically, geographically, and ideologically situated.We imagine this special issue as an opening toward a critical dialogue, not only about how such an approach might be enacted in practice but also about the far-reaching ways development paradigms have shaped both our objects of study and the contours of the field itself. The decision to center institutionally sponsored films across all the essays in this issue is deliberate and enables us to highlight institutional critique as a vital methodological imperative within our analytical framework. Created within the frameworks of international organizations, state agencies, or NGOs, these filmsâ histories make legible the institutional logics that underwrite their production. Yet our critique does not stop at these specific entities. Rather, we argue for a broader interrogation of the political conditions and institutional infrastructures that shape media and knowledge production more generally. This includes contemporary corporations embedded in the digital platform economy, from streaming services to the rapid expansion of AI. Equally critical is a reflexive examination of academia itself, where departments of economics, political science, and centers for development have played a formative role in producing and legitimizing developmentalist theories and policy frameworks. While the humanities and arts have at times offered critical alternatives, they have also frequently mirrored and reinforced many of the same developmentalist assumptions. A feminist analysis of the nexus between development and media must therefore unsettle not only dominant archives but also the institutional and disciplinary foundations of our own scholarly practices.As scholars, we share the complex position of navigating the same tensions between institutional complicity and emancipatory aspiration as many of the media-makers whose work we study. Mirroring our subjects is also the transnational, collective mode of this special issueâs own production as it emerges from an ongoing informal working group we have sustained over several years. While relying on institutional and disciplinary affordancesâsuch as university funding for conferences or access to academic publishing platformsâwe have been working toward creating a community that exceeds, and often resists, the prevailing logics of our academic institutions. Our aim has been to create a space for shared inquiry and mutual support that pushes back against disciplinary siloing and technocratic neoliberal assessment modes of both labor and knowledge productionâand this certainly extends to our experience collaborating with the journal editors throughout the publication process. Our goal has been to examine both the persistence and variability of developmentalism, understood as what Gustavo Esteva calls a âpowerful but fragile semantic constellation,â as a conceptual formation that has historically inspired, legitimized, and mobilized media projects across Asia, Africa, and Latin America.21 And gendered biopolitics, from population control to gender mainstreaming, have remained integral to development policies and media practices, recurring across formats from institutional newsreels to film festivals.We share the conviction that, far beyond the history of nonfiction institutional media, development (as both a broad ideological project and a network of material and institutional practices) and developmentalism (as a set of discourses and theoretical models associated with development) have exerted a far-reaching influence on film and media cultures at large. As such, they must be treated as a major force in shaping global film and media systems and also the many ongoing assumptions behind their critical discourses. The discipline of communication studies was founded on modernization theory governed by Cold War goals of dissemination of Western liberal democracy around the world, while âan area studies framework allowed compartmentalizing Western and non-Western outcomes of technologies that were always claimed to be universal.â22 Despite critique from postcolonial and critical race studies, many of these frameworks have remained foundational for media theory.23 In historical scholarship, as we increasingly move beyond âmodernityâ as a dominant conceptual anchor, engaging with practices and discourses of development opens more precise analytical pathways. These film and mediaâs entanglements with the logics of and economic and the associated with as well as their conceptual underdevelopment, and impact in as diverse as and of media aesthetic and paradigms in film and film and funding are developmentalist assumptions to the they to underwrite the narrative and logics of and global media from the structure of the film to the cultures of argue that a examination of the historical entanglements between film and developmentalist aesthetics, modes of as well as infrastructures and critical the and that our contemporary media is a of the historical contours of development as a field of inquiry embedded within a of some of the methodologies by the featured in this special a of this complex history, to the larger at in media, development, and gender all its development a it as an of be with practices as divergent as and in In as we work on this the of the of the USAID the ideological that have the history of international the and of this on the global its a from development as a global practice and as an institutional and which over the has as a with its own media Yet or does not erase the historical impact of these the contradictions they have reflected and over the as the of development several crucial to the economic theories of development initiatives to and through the of the development an international policy framework at from the Global to the of the Global the by the political role of and the of the International the on was challenged by dependency theory and at development as global structural the neoliberal of the the Programs by the and World imposed and as conditions for and forms of assistance became known as the major markers for international development development has moving beyond economic to such as the Human Development and the Development and from international organizations such as the United Nations to a broader network of These frameworks increasingly of and liberal of and with what in many ways to various while the of the to developmentâs epistemological more scholarship has toward a of its and material the field has to a of and critical by and scholars, which development as a dynamic of conceptual and political to these the studies in this special issue call for sustained analysis in place of In we draw from a of and that in of of gender and to this special issue engage that and from Mexico to contemporary specific local historical of global distinctly feminist methodologies as well as attention to studies that this issue a in the global history of development on and documentary work in Mexico how early women infrastructures as of while US films an early of state and transnational on a outside the Global as the of developmentalist both the and markers of development media, its to the and Latin central grounded in archival also womenâs in transnational and the methodological of archives on study of the series to a a digital media not by but by women not as but as subjects and within circuits of neoliberal and the aesthetics and of how developmentâs has models of to contemporary neoliberal paradigms of and analysis how digital and gender and practices, discourses on and their of these essays the of some of the historical of developmentalist as the question of the role of the state within such on a notion of economic as a and the dominant of development that the state as the for and through infrastructural projects.
