Abstract

The rapid growth of transaction operation data has introduced significant challenges related to balancing the need for data sharing and ensuring privacy protection. As transactions increasingly become more complex and data-driven, the sharing of this data across various stakeholders, while maintaining confidentiality and integrity, has become a critical concern. The contradiction between the transparent and immutable nature of transaction data in distributed systems and the need for stringent privacy measures presents a unique problem for industries dealing with sensitive transaction information, such as finance, healthcare, and e-commerce.In response to this problem, a novel blockchain-based transaction operation data sharing scheme, named BBTDSS, is proposed for the Identity and access management system. This scheme is designed to leverage blockchain technology for secure data sharing while implementing a crop quantum homomorphic encryption algorithm to ensure that transaction data remains private during processing and sharing. Blockchain's decentralized and immutable characteristics provide a robust framework for transparent data management, enabling multiple participants to access shared data without the need for a trusted central authority. However, the challenge of protecting sensitive transaction information is addressed by integrating homomorphic encryption, which allows computations to be performed on encrypted data without decrypting it. This ensures that the privacy of individual transaction details is maintained, even while enabling the secure sharing and processing of data across different parties.The introduction of crop quantum homomorphic encryption further enhances the security and scalability of the system by harnessing the power of quantum computing principles to perform more efficient and secure encryption operations. This approach significantly reduces the computational burden typically associated with traditional encryption methods, making the system more efficient and practical for real-time transaction processing.In essence, the BBTDSS scheme provides a solution to the ongoing challenge of data privacy and secure sharing by combining the strengths of blockchain and advanced encryption techniques. It ensures that transaction operation data can be shared securely among authorized parties, while safeguarding sensitive information from unauthorized access, thus paving the way for more transparent, efficient, and privacy-preserving transaction systems in various domains.
