The introduction of smart devices and the IOT network has led to the creation of large amounts of data that require protection from intrusion. Most users desire to have personal data kept confidential while seeking for platforms that would prohibit their vendors from distributing it to third parties without their consent. However, the users that are conscious of data privacy often share information with third parties, contradicting their intentions in keeping their information confidential. The difference between user intentions and actions regarding data privacy is called privacy paradox while privacy fatigue refers to the weariness of people on implementing security and privacy solutions. In this proposed system we design and develop smart contracts to provide interaction for the IoT device and company which require personal data. A company or Application requests personal information from the device to share the device sends, that information to the smart contract, smart contract uses dynamic rules to check PII in the users' personal information. Base on the PII(,) system would alert users on the limit and risk of sharing personal information through a public network. We used solidity programing language for the modeled of the smart contract. The performance of the contract is evaluated on the Repsten test network.

Blockchain technology is a scientific and technological project that countries around the world have been paying close attention to and researched and developed in recent years, and it is one of the most popular technologies in the world. Blockchain is a kind of bookkeeping technology that is jointly maintained by multiple parties, uses cryptography to ensure transmission and access security, can achieve consistent data storage, is difficult to tamper with, and prevents denial. It is also called distributed ledger technology and has distributed credibility. Technical characteristics such as not easy to be tampered with, and multi-party maintenance. The new infrastructure of chain network collaboration will use network identification as a key digital resource as a breakthrough point to promote the application and development of blockchain and realize the engine role of new infrastructure. Through the collaborative development of blockchain and the industrial Internet, the new infrastructure of chain network collaboration is committed to building a national-level distributed trusted application innovation carrier. Provide a unified identity authentication mechanism, object identification mechanism, and value exchange mechanism for digital applications to reduce the cost of using digital technology.
<em>Any number of gadgets can be associated with a Wi-Fi remotely. Anybody inside scope of the Wi-Fi can endeavour to get to the system. Due to this, Wi-Fi is progressively powerless against assaults. Consequently, client touchy data is at the danger of being misused. The clients’ security and security can be ensured by unknown verification. When they use the hotspots that are very easy to access to everybody, privacy plays an important role. The existing solutions which will validate the users but do not take the responsibilities of the users or they are always dependent on intermediators. The latest development of or concept of colored coins and coin shuffle can be used to protect the users who are connected to the network without compromising or leaking any information. The bitcoin blockchain is very impressive and robust that will help to manage the user information and also very helpful to determine the possession of the users framework.</em>
In this paper, we present a certificate management platform for performance assessment during recruitment using blockchain. Applicants are awarded certificates according to a predetermined level of progress based on their performances. All certificates are stored on a recruitment management platform that serves as an environment for storing and presenting all awarded certificates. The hashed information of all the certificates are stored in the blockchain, and once stored, the contents cannot be tampered with. Therefore, anyone can check the validity of the certificates using this blockchain. Our proposed platform will be useful for recruitment and application management, career management, and personal history maintenance.
The digital competence is necessary for 21st century living, but from several countries survey, a large number of people still have insufficient digital competence. Moreover, from literature study found three problems of today cooperative education information system, (1) lack of information sharing among university community, (2) lack of connect information to public, and (3) lack of enhancing 21st century learning skill. This paper proposes a process design of cooperative education management system by using the integration of cooperative education, E-Portfolio, digital competence framework 2.0, cloud computing technology, and blockchain technology. These processes make result of digital competence assessment credible and share to open digital labor market finally.
The article discusses the features of distributed ledger technology based on the use of decentralized peer-topeer networks. The history of the emergence and development of distributed ledger technology considered in detail, the prerequisites for the growth of its popularity in various fields are analyzed. The main advantages and disadvantages of distributed ledger technology in general, as well as decentralized (permissionless) and exclusive (permitted) blockchain platforms in particular, are revealed. The principles of functioning of cryptocurrencies on the basis of blockchain technology, including their issue (coinage) are described. The state of blockchain technologies from the point of view of technology maturity is considered. The main trends in the development of blockchain technology at the present stage are revealed. An analysis of the possibilities of using distributed ledger technology of public administration, including in the education system, in order to improve the safety and automation of functions is presented.
Over the past few years, the importance of improving the product distribution structure has increased worldwide. Therefore, distribution prices are now disclosed and product information is shared with consumers. However, distribution channels are complex and supply chain management (SCM) is autonomously executed in each company. For this reason, it has been frequently pointed out that the distribution process is not transparent and the distribution margin is high. In this paper, we propose a system that guarantees the transparency of the product distribution structure by applying blockchain and smart contracts to the price-tracking portion of supply chain management systems. This approach allows companies to track their trades by enhancing transparency in the SCM, thereby discouraging companies from pursuing excessive profits. In addition, companies can cut management costs by automatically storing distribution details in a blockchain network and managing information more securely.
The blockchain is one of the main mechanisms enabling Bitcoin to be a decentralized electronicpayment system. It provides the system with a shared transaction history, which can be verified byevery participant. With increased use, it has become apparent that there is limited possibility forscaling this to handle more transactions. Payment channel networks are one proposed solution tothis problem. They allow for more transactions to be done by moving some transactions to a sepa-rate network. The Lightning Network is one such network, which uses Bitcoin and the blockchain tooperate. While the transactions in this network will not be included in the blockchain, there will bedata there related to the network. This is because it needs the blockchain to manage the paymentchannels which the network consists of.In this project we have explored the blockchain with the goal of identifying transactions relatedto the Lightning Network, and by doing so, determine what information about it is available in theblockchain. We have created different methods for identifying these transactions. The methods usedifferent transaction characteristics differing in uniqueness, making some methods more precise,but having fewer results, and vice versa. We created software implementing the methods, whichwere used to parse the blockchain. The effectiveness of these methods have been quantified bycomparing the data we found when parsing the blockchain, to data we collected directly fromthe Lightning Network. The results shows that the methods are viable for identifying a subset oftransactions, and that precision can be sacrificed for finding more. By identifying these transactionswe were able to determine what information about the Lightning Network we can see from theblockchain perspective, and also some aspects where we are limited.We have also adapted heuristics from previous work doing blockchain analysis to our scenario.These were used to link related information we had found when parsing the blockchain, whichenabled us to create network graphs showing the relations between the Lightning Network channelsidentified on the blockchain. While the relations in this network graph were limited, comparedto the actual relations found within the lightning network, they show how the blockchain canbe used to infer non-explicit information about the lightning network. We have also identifiedseveral methods for potentially inferring or locating more information using what is available inthe blockchain.
Intelligent space is an environmental robot system where many intelligent sensor nodes are distributed for supporting humans and mobile robots. This paper introduces a blockchain-based sensor network system for the intelligent space. Blockchain is a system for distributed ledgers of crypto currencies such as bitcoin. Recently, blockchain is considered to be effective for construction of distributed sensor network systems without central servers. In this paper, a prototype sensor system with blockchain based on Ethereum is introduced for intelligent space.
