PEER TO PEER DIGITAL RIGHTS MANAGEMENT USING BLOCKCHAIN

Content distribution networks deliver content like videos, apps, and music to users through servers deployed in multiple datacenters to increase availability and delivery speed of content. The motivation of this work is to create a content distribution network that maintains a consumer’s rights and access to works they have purchased indefinitely. If a user purchases content from a traditional content distribution network, they lose access to the content when the service is no longer available. The system uses a peer to peer network for content distribution along with a blockchain for digital rights management. This combination may give users indefinite access to purchased works. The system benefits content rights owners because they can sell their content in a lower cost manner by distributing costs among the community of peers

Analysis of IoT and Blockchain Technology for Agricultural Food Supply Chain Transactions

The Block chain is a peer to peer, distributed ledger in which members must establish consensus to record every new input and transactions that are stored by all members. Over the last decade, block chain technology has grown in popularity, attracting interest from a wide range of industries, including finance, manufacturing, energy, and government sectors, health, and agriculture supply chains, land registrations, and digital identifications (IDs). Block chain facilitates better opportunities and benefits in agriculture, as well as building trust between farmers and consumers and allowing the creation of reliable food supply chains. The Chapter discusses how block chain and smart contracts can improve productivity, transparency, and traceability in agricultural insurance, smart farming, and agricultural food supply chain transactions (AFSC). By applying Block chain agri-food supply chain tracking was made easy and won the trust from different stakeholders, which was a real benefit to the real heroes of the country. The consumer can research the history of a product they are thinking about buying and consume food in their cart, learning about the entire process from planting to harvesting, transporting, and selling. Food fraud may be reduced by using the traceability and integrity of financial information to detect untrustworthy intermediaries and business practices that exploit both independent farmers and cooperatives. The agricultural industry will be transformed by block chain for supply chain management. All phases of the agriculture supply chain are being simplified, enhancing food safety and preventing the sale of counterfeit goods. Access to agricultural finance services for farmers and companies could also be facilitated by the technology. This Paper presents a review and research challenges on the existing block chain based IoT applications in the agriculture domain where maximum research focuses on food supply chain and its security of Internet of things with Block chain. The chapter presents how block chain and smart contracts can increase productivity, transparency and traceability could be very effective in Agricultural insurance, smart farming, transactions of agricultural food supply chains

I Rest My Case! The Possibilities and Limitations of Blockchain-Based IP Protection

We have identified, mapped and discussed existing research on Blockchain-based solutions for intellectual property (IP) protection, an investigation that emerged from a case in antibody production for scientific and medical applications. To that end, we have performed a systematic literature review and created an instrument that classifies the contributions according to the materiality of the object they protect (from immaterial to physical), the type of protection (authorship notarization or prevention of illegal use) and the type of research (conceptual or empirical). Our results can be used to understand which avenues to pursue in the effort to create a new generation of more effective technology-assisted IP protection systems, a priority for 152 signatory countries of the patent cooperation treaty

THE ROLE OF BLOCKCHAIN TO SOLVE PROBLEMS OF DIGITAL RIGHT MANAGEMENT (DRM)

In recent years, internet user was grown significantly. Even though many problems arise due to internet abuse. The sectors affected by the internet is digital assets or digital right. Various ways are done to solve the violation. One of that ways is to develop digital protection or Digital Right Management (DRM). However, the DRM technology has several disadvantages such as there is no way to track the leak and prove a copyright violation, the user is unable to authenticate the content since the content source is unknown, there is no user restriction to download the content, the system isn’t provided the feature to alienate ore transfer ownership the content to other, and the system using centralize model that requires many issues, especially trust issue. Fortunately, the blockchain is a decentralized, secure, reliable, immutable, and tamper-proof paradigm. The blockchain is also built upon public key cryptography and has a smart contract that can solve or complement DRM problems. This paper discusses how the blockchain solves DRM problems. The results show that blockchain solves DRM problems. A narrative literature review was conducted with several stages, including a source search of papers, articles and news articles on digital rights management and blockchain in the last five years. The next step is to identify keywords related to the topic, to review the sources, and to compile the paper

LightChain: A DHT-based Blockchain for Resource Constrained Environments

As an append-only distributed database, blockchain is utilized in a vast variety of applications including the cryptocurrency and Internet-of-Things (IoT). The existing blockchain solutions have downsides in communication and storage efficiency, convergence to centralization, and consistency problems. In this paper, we propose LightChain, which is the first blockchain architecture that operates over a Distributed Hash Table (DHT) of participating peers. LightChain is a permissionless blockchain that provides addressable blocks and transactions within the network, which makes them efficiently accessible by all the peers. Each block and transaction is replicated within the DHT of peers and is retrieved in an on-demand manner. Hence, peers in LightChain are not required to retrieve or keep the entire blockchain. LightChain is fair as all of the participating peers have a uniform chance of being involved in the consensus regardless of their influence such as hashing power or stake. LightChain provides a deterministic fork-resolving strategy as well as a blacklisting mechanism, and it is secure against colluding adversarial peers attacking the availability and integrity of the system. We provide mathematical analysis and experimental results on scenarios involving 10K nodes to demonstrate the security and fairness of LightChain. As we experimentally show in this paper, compared to the mainstream blockchains like Bitcoin and Ethereum, LightChain requires around 66 times less per node storage, and is around 380 times faster on bootstrapping a new node to the system, while each LightChain node is rewarded equally likely for participating in the protocol
