This project presents a privacy-preserving data sharing system using attribute-based encryption (ABE) in cloud computing environments. The primary objective of this system is to ensure secure and controlled access to sensitive data while maintaining user privacy. With the increasing use of cloud storage, data security and unauthorized access have become major concerns in existing systems.To overcome these challenges, the proposed system utilizes attribute-based encryption, which provides fine-grained access control based on user attributes rather than simple identity-based mechanisms. In this approach, data is encrypted using a set of defined attributes, and only users whose attributes match the access policy can decrypt and access the data. This enhances both security and flexibility in data sharing.The system is designed and implemented using modern technologies to simulate real-world cloud storage scenarios. The results demonstrate that the proposed solution effectively prevents unauthorized access, ensures data confidentiality, and improves overall system security.In conclusion, this project provides a scalable and efficient solution for secure data sharing in cloud environments and can be applied in domains such as healthcare, finance, and organizational data management where privacy is a critical requirement.
