Blockchain for secure Data Sharing: Enhancing Security and Trust in Inter-organizational Exchange

Abstract

Blockchain technology has changed the way people share secure data by providing an autonomous, unchangeable, and cryptographically secure structure. Instead of traditional controlled systems that have trust problems and single points of failure, blockchain allows for a distributed ledger system where everyone shares confirmed, unchangeable records without the need for middlemen. Its immutability protects the purity of the data, and its openness encourages cooperation without trust, which lowers the risk of illegal access. Cryptography and smart contracts make data more secure and make the sharing process more automated. Blockchain's ability to keep private data safe is shown by its use in real life in healthcare, banking, and supply chain management. But problems like scaling, energy use, communication, and following the rules still exist. New ideas like Layer 2 scale, energy-efficient decision methods, and cross-chain connectivity look like they could help get past these problems. As blockchain technology develops, it has a lot of potential to solve important data security problems. This could make it a key part of safe data sharing between organizations in the digital age
