Secured Data Sharing using Blockchain

Abstract:

Among the primary concerns in the digital era, secure sharing of data stands prominent. The integrity, confidence, and authenticity of information being shared form a very significant concern. Blockchain technology promises much towards overcoming such challenges due to its decentralized and immutable nature. It significantly enhances data security through its use of encryption techniques, such as hashing and digital signatures, which eliminate the need for middlemen in transactions while also reducing the probability of data breaches. It leverages smart contracts that provide mechanisms for automating access controls wherein data is shared appropriately, according to agreed terms, among the participants in a trustless environment. Some practical illustrations of use cases from healthcare, supply chain management, and finance are found in the context provided below. Findings thus reveal the needed innovation to revolutionize the state of secure data sharing on blockchain technology by providing a strengthened, decentralized infrastructure that promotes trust, transparency, and accountability of stakeholders involved.
