Abstract

The rise in data volume that is generated every day has influenced the end users to adopt cloud storage systems to meet their requirements. The user is concerned about the integrity and privacy of the data that is stored online even though the cloud service providers ensure maximum confidentiality, integrity, and availability. The users also have to provide access to the data to other data users in certain cases. To tackle these challenges, utilizing a blockchain-based solution can offer transparency and enable data access sharing without the need for a trusted third-party verifier. In this research project, a data access-sharing system is developed by utilizing the permissioned nature of Hyperledger Fabric that will create a network of verified participants and help to maintain trust with each other while sharing data. Hyperledger Fabric offers an added advantage in designing solutions for organizational use cases by providing higher scalability and privacy than using public blockchain systems. A test prototype of the system was developed for creating a data access sharing system between data owners and data users and evaluated to verify the research study. The evaluations based on the testing and benchmarking performed show that the system implemented offers a significant performance such as high throughput and less latency.
