In the last decade, blockchain technology has seen adoption to infinite domains, health care sector is one of the major domains where there are a greater opportunity and advantage to leverage the benefits of distributed ledgers in storing and securing patient medical records. The Government of India is also very keen on digitization in addition to their wider adoption of blockchain technology to serve the citizens by ensuring their privacy and security of personally sensitive. In this paper, we propose a framework for the secure management of patient medical records based on the Ethereum blockchain. The PMR is tokenized using the ERC-721 standard which is a Non-Fungible Token that can be uniquely mapped to the individual patient. To ensure a higher level of security and non-redundancy, the medical records are stored and maintained in distributed storage like InterPlanetary File System ; to ensure privacy, the patient’s sensitive information is anonymized through a privacy-preserving scheme. To provide complete control of the medical record to individual patients, we have employed a secret sharing scheme with essential share that is owned by the patient. The proposed framework aims to provide correctness and consistency in managing the PMR over its life cycle.

Huge adoption of the InternetKripa,M. into our daily lives generates at leastNidhin Mahesh,A. few MBs of data. Social media in modern age enabled everyRamaguru,R. single user with a smartphone and Internet toAmritha,P. P. be a marketer, journalist, publisher and content creator. Ensuring protection and copyright of social media data like images, videos and audios are extremely demanding. Copyright infringement happens easily, and protecting the content for its originality and authenticity should be simplified. In this paper, we are proposing a blockchain framework with smart contracts to protect social media contents using IPFS, a modern decentralized file storage system and a secret sharing scheme. This framework through its decentralized and immutability feature offers limitless opportunities for managing copyright rights of content on decentralized social media.

Recent advancements in the Internet of Things and mobile internet helped the development of traditional Vehicular Adhoc-NETwork based systems into the Internet of Vehicles. Vehicles in IoV make decisions based on the information from other vehicles and roadside infrastructure. This information helps them make critical decisions and alert the user about unpredictable situations. Security and privacy concerns in vehicles are increasing, hence it is important to address these issues, thus preventing malicious nodes transmitting falsified information or tampering critical communication data. In this paper, we propose RealTime Blockchain for the Internet of Vehicles for ensuring authentication and maintaining secure communication between the vehicles. The blockchain keeps track of communication information between vehicles to provide accountability. This paper also introduces smart contracts based vehicle services like automatic toll payment, vehicle servicing slot booking and payment, fuel payment, vehicle insurance renewal, etc. The proposed blockchain supports native cryptocurrency for the payments within the network.
