Food safety is an important issue in today’s world. Traditional agri-food production system doesn’t offer easy traceability of the produce at any point of the supply chain, and hence, during a food-borne outbreak, it is very difficult to sift through food production data to track produce and origin of the outbreak. In recent years, blockchain based food production system has resolved this challenge, however, none of the proposed methodologies makes the food production data easily accessible, traceable and verifiable by consumers or producers using mobile/edge devices. In this paper, we propose FoodSQRBlock (Food Safety Quick Response Block), a blockchain technology based framework, which digitizes the food production information, and makes it easily accessible, traceable and verifiable by the consumers and producers by using QR codes. We also propose a large scale integration of FoodSQRBlock in the cloud to show the feasibility and scalability of the framework, and experimental evaluation to prove that.
Blockchain technology can be used to solve the problem of the management of the digital copyright. Though some related ideas have been proposed, few papers propose a complete digital copyright management system based on public chain and simulation. A system based on public chain enables copyright owners and users to trade directly without resorting to a centralized organization. In this paper, a secure digital copyright management system based on Ethereum is proposed. Firstly, a model is established based on smart contracts and InterPlanetary File System. Secondly, use the improved ELGamal encryption algorithm to encrypt session data and protect privacy and evaluate the efficiency of the improved algorithm. Lastly, a transaction watermark that is consistent with the transaction information on the chain is added to the image data, providing proof for the piracy.

Even with the ability to produce documents digitally, the paperless environment has yet to become a reality in South Africa. Hardcopy documents are still printed daily which makes them susceptible to document fraud. In South Africa, a case was reported recently, where someone who was creating fake documents was exposed. This introduces the challenge when using hardcopy documents which is loss of integrity. Thus, it is vital to have systems in place to verify document integrity and be able to determine when a document has been tampered with. Various techniques have been used to secure documents, yet the challenge persists. The combination of 2D barcodes, digital signatures, Optical Character Recognition (OCR), cryptographic hashing has proved the potential to achieve good results when combined. Recently, blockchain has been added as one of the techniques to be employed for document verification. This paper presents a proposed solution that incorporates the combination of 2D barcodes, OCR, cryptographic hashing and blockchain. As this is still on-going work, experiments are still required to demonstrate the viability of the solution.

This paper is executing a food menu function for customer to search as well as upload food in sequence. Nowadays, mobile devices with wireless technologies have appeared into the humanity industry in particularly restaurants with the development of food ordering system. Most of the restaurants are used in the manual ordering system, which is involving papers and pen. In this method has can be very slow and can occur in error in noting down the users orders. Additionally, large numbers of peoples are needed to use the online ordering system. It is more helpful and reduces the users waiting time. In this work presents the customer has been creating the registration he/she then the password will be generated. The user can create the account and login into the system and show the restaurant food menu details. Select the food item from the menu. Adding the customer data will be updated and delete the food orders from the menu bar. Update the cost of product details and update the additional information like photo, description etc. If the customer no need item remove all items from the current order and to show the payment details as well as type the location from the mobile. Finally, the notification SMS can be received from the mobile and view the place order. The existing supply chain method is not efficient enough to take care of the food safety at every stage. Due to in efficiencies in the food supply chain, food industry faces countless challenges.But the rising distributed ledger technology; block chain can improve the food safety by connecting multiple stakeholders like farmers, processors, retailers, as well as consumers.
In the past, the improvement of digital copyright protection system based on digital watermarking mainly focused on algorithms, while generation and storage of the watermark information was ignored. In this paper, a new design scheme of copyright management system based on digital watermarking and its information, such as blockchain, is proposed, which combines digital watermarking, blockchain, perceptual hash function, Quick Response(QR) code, and InterPlanetary File System(IPFS). Among them, blockchain is used to securely store watermark information and provide timestamp authentication for multiple watermarks (multiple copyrights) to confirm the creation order. Perceptual hash function is used to generate hash value based on the structure information of images, that watermark information can be confirmed without the original image. QR code is used to generate QR code images containing image hash and copyright information as watermark images to improve robustness and capacity of digital watermarking; IPFS is used to store and distribute watermarked images without a centralized server. This scheme can enhance the effectiveness of digital watermarking technology in the field of copyright protection. In this way, use P2P network to integrate and complete copyright management and distribution of copyrighted works without requiring a trusted third party. Nodes rely on cryptography to confirm the identity of each other and ensure the security of information. It can reduce information leakage, data destruction and other risks caused by collapse of the centralized system in the past. This improves the security and transparency of information, and speeds up the distribution of copyrighted works to facilitate circulation in the network. This scheme can also improve copyright protection of multiple creations. Combine blockchain and multiple digital watermarks to record copyright information of every copyright owner in the authoring process and fully prove this information. In order to protect the legitimate rights and interests of each copyright owner.

The usage of cell (mobile) phones has increased over the years. As newer and more advanced cellular technology is introduced, the question of what will be done with disposed or retired cell phones becomes a pressing one. Currently, this problem has an impact on the environment, as e-waste in landfills is a growing concern. Many have offered solutions to this problem, some that involve recycling the materials the cell phone is made of or extending the length of the contract so that users keep their cell phones longer. However, in this paper, we provide an alternative to these methods by using our model to determine if a retired cell phone can be repurposed by identifying its functional components and its sensor capabilities. Given this information from our model, a repurpose-capable cell phone can then be used to develop useful smart campus applications and can potentially reduce the number of retired cell phones that become e-waste.

OBJECTIVE: This paper aims at proposing a new framework for the classification of RFID deployments in fashion and apparel retailing. The framework encompasses several different use cases (UCs) pursued by fashion and apparel retailers in the last decade, and updates, expands and goes beyond what has already been presented in the related literature. DESIGN, METHODOLOGY, APPROACH: We carried out a comprehensive literature review on RFID deployments in fashion and apparel retail. We searched different sources of information, that is, scientific papers, conferences and seminars proceedings, websites, magazines, newspapers etc., up to 160 papers that were carefully analysed and organised in a structured database. This data set also comprehends information from confidential projects. We analyse contents on the level of single RFID projects, that is, feasibility studies, proofs of concept, pilots or deployments. For each project, we determine what specific UCs were at stake. Eventually, the framework of all possible RFID UCs emerged from the analysis, and we set up a panel of industry partners to validate the framework using the Delphi method. FINDINGS: We structured the new framework along two levels: first, 6 categories were identified (i.e., level 1 use cases). Each category was then detailed, resulting in a total of 18 specific UCs (i.e., level 2 use cases). Each level 2 UC corresponds to a very specific objective pursued by an RFID implementation. For each UC, we propose a set of business metrics to evaluate deployment success as well as benefits achieved. PRACTICAL IMPLICATIONS: From a practitioner’s perspective, the framework offers a comprehensive and well-structured overview of the cost- and the revenue-related potentials of RFID implementations in the industry. Researchers, on the other hand, may use the framework to identify opportunities for further research regarding RFID deployments in retailing. ORIGINALITY/VALUE: Our framework is based on the current body of literature, and complements prior studies, which served as the starting point for our research.
In the article we overview how to implement zero knowledge proof authentication protocol in the web. The proposed system consists of two parts: a server side and Android application. Despite the classical password-based approach, users have to install special application and use it as authentication manager. We use QR-codes to send necessary data from the server to the application, so login experience is just scanning this code. Finally, because of zero knowledge proof features the system is resistant to interception, secret-cracking and fishing, so supposed even to use on insecure public devices.
Government officials and industry experts increasingly highlight today's data privacy and security vulnerabilities require new approaches to mitigate risk. Additional methods and techniques to address current vulnerabilities are needed especially between responsible parties within a large ecosystem like finance, healthcare, and education. New approaches leveraging cryptographic ledgers and blockchains are emerging as a potential solution. This paper proposes a layered architectural approach for cryptographic ledgers to aid in security and privacy controls of digital solutions.
The RFID tag offers a viable and powerful replacement for barcodes.The challenge in providing security for low cost RFID tags is that they are computationally weak devices,unable to perform even basic symmetrickey cryptographic operations.In this paper,the risk of security in RFID technology is discussed,so the authentication protocol is very necessary.However,there are some disadvantages in the two types of authentication protocols which are widely used at present.An authentication protocol based on zero knowledge proof which is suitable for RFID technology is put forward,and its validity and performance is analyzed.
