Item Inter-Planetary File System Enabled Blockchain Solution for Securing Healthcare Records(Institute of Electrical and Electronics Engineers Inc., 2020) Marangappanavar, R.K.; Manjappa, M.The sharing of health-related data has become challenging in terms of data security which may lead to compromise patient's privacy. Generally, once the report generated by the health provider is final, it will be uploaded to the hospital's private repository. When it comes to the hospital as an organization, many participants [Doctor, Patient, Researcher, Insurance company] requires the report of patients for one or other reasons. Providing a single platform for all participants to share confidential data securely is a difficult and challenging task. Care should be taken such that the personal data of the patients should not be misused or tampered. Existing methods have been proved insufficient to effectively manage and secure health records. Blockchain technology, a recent research trend, has shown promising results for such secure data sharing. Since the contents of blockchain are tamper-proof, all participants can access the data but cannot change the data. By employing smart contracts and access control programs one can monitor data activity in the blockchain network. In this article, a blockchain architecture has been designed and discussed for secure and easy sharing of patient's Personal Health Report(PHR) among the different players of health organization. Further, Inter-Planetary File System (IPFS) has also used in the proposed blockchain architecture for faster retrieval of PHR's. We demonstrate the strengths of our proposed model, its user-centric focus and also the experimental results. © 2020 IEEE.Item Securing Database Backups Using Blockchain and Peer-to-Peer Network(Institute of Electrical and Electronics Engineers Inc., 2021) Maheshwarkar, A.; Kumar, A.; Gupta, M.Databases are one of the critical services provided by a cloud environment. Database downtime can have a devastating impact on any running service. Database backups are generally made robust with high availability by replicating them in a new server. However, storing a database backup on a new server is not cost-effective. At the same time, storing the backup in the same server does not ensure high availability. In this paper, we propose creating a secure database backup architecture using a transaction blockchain and peer-to-peer network to record the history of the transactions. Our architecture makes database backups highly available with a 4 percent decrease in throughput. © 2021 IEEE.Item Fully Decentralized Blockchain and Browser-Based Volunteer Computing Platform(Springer Science and Business Media Deutschland GmbH, 2022) Bharadwaj, K.S.S.; Dharanikota, S.; Honawad, A.; Divakarla, D.; Chandrasekaran, K.Volunteer computing allows individuals, who have access to computing resources that are currently idle, to allocate them to perform useful work. This paradigm has existed since a long time and is evolving by the day with the advent of novel approaches such as browser-based volunteer computing. But most of these solutions have a degree of centralization in their architecture and are prone to single point of failure issues, or require explicit trust in the entities that manage the network. This paper proposes the use of blockchain to eliminate these drawbacks of traditional volunteer computing platforms, at the same time preserving the ability to make the architecture entirely browser-based. The key focus of our proposal is on resilience. Resilience is achieved by making use of the decentralized storage system, InterPlanetary File System. Finally, we present a prototype implementation of our ideas. We evaluate our system by solving NP-problems using the prototype. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.Item Swaasthya Sampathee: Blockchain based EHR Framework(Institute of Electrical and Electronics Engineers Inc., 2022) Sadashiv, N.; Vachana, S.G.Advancement in the field of technology has trans-formed healthcare system with increased healthcare records. Electronic health records (EHR) helps improve wellness of patient and promotes quality of medical care. However, lack of ubiquitous access to fool proof EHR leads to poor health care facilities with higher expenses. Traditional approaches of storage and access of EHR compromises the ownership, authenticity of the records along with privacy and security issues. To mitigate these issues and promote widespread adoption of EHR especially in rural areas, an Ehereum's Ropsten blockchain based EHR framework in cloud environment is presented in this paper. The framework and its implementation is based upon the use of asymmetric cryptographic keys to securely store the EHR on Inter planetary file system (IPFS) and provide controlled access. The blockchain powered EHR facilitates security and privacy of patient's records and renders authorized ubiquitous access of patient's EHR. © 2022 IEEE.Item BlockFIR: Blockchain based First Information Report System(Institute of Electrical and Electronics Engineers Inc., 2023) Kamble, S.; Chandavarkar, B.R.India is experiencing a sharp rise in criminal activity. This is a serious problem, as many of these crimes go unreported. Although there is an online platform for the police to store First Information Reports (FIR) and Non-Cognizable Reports (NCR), most FIRs are still written by hand. This is inefficient and can lead to errors. Additionally, the complainant must typically be at the police station to report a cognizable offense. This can be inconvenient and time-consuming, especially for victims who live in rural areas. In 2009, the Crime and Criminal Tracking Network and Systems (CCTNS) were launched as an efficient e-governance system. This system has helped to improve the reporting of crimes, but it is still a centralized system. This means that it is vulnerable to cyberattacks and can be easily shut down by a single point of failure. Therefore, a fully decentralized system is required to ensure no single point of failure and that complaints are handled safely and securely to prevent unauthorized access. This paper proposes a blockchain-based solution called BlockFIR to manage complaints against cognizable and non-cognizable offenses. Using this system, complaints can be registered by users. The police stations will be able to see complaints registered in their jurisdiction, register FIRs/NCRs accordingly, and take action on them. Through a prototype implementation using Go-Ethereum (Geth), smart contracts, and Django web server, we demonstrate the practical use of BlockFIR. We show that our system can be easily used by users, police personnel, and Higher Authorities to improve the current systems in India. © 2023 IEEE.Item Utilizing NFTs to Revolutionize Document Verification and Authentication through Blockchain: Redefining Trust in the Digital Era(Institute of Electrical and Electronics Engineers Inc., 2024) Kumawat, N.; Naik, D.The significance of certificates issued by educational institutions for graduates cannot be overstated, as they serve as crucial documents for verification purposes in various contexts such as employment and passport verification. However, traditional verification methods are often costly and inefficient. This research paper aims to introduce a blockchain-based framework for certificate verification, leveraging features such as hashing, digital signatures, and public/private key cryptography inherent in blockchain technology. By incorporating additional security measures like biometrics and encryption for secure document storage using IPFS (Inter-Planetary File System), this framework ensures the integrity and authenticity of certificates. The utilization of blockchain not only enhances the security of data storage due to its immutable nature but also streamlines the verification process, offering a cost-effective and efficient alternative to traditional methods. © 2024 IEEE.
