Abstract: In the contemporary logistics industry, user privacy data is usually kept by third parties, which often lead to users lack control over logistics information data. This paper proposes a novel logistics user privacy protection scheme based on layered encryption and blockchain technology. The scheme proposes a novel access rights management mechanism based on blockchain and DAA anonymous authentication to implement the privacy data access rights management and the traceability of private data access records. In addition, the scheme adopts a nested access control tree structure enables users to determine the access rights of their private data according to the attributes of the data accessor. Finally, this paper designs and implements a logistics order proofng verifcation system. The security analysis shows that the system can ensure the security of private data efciently.

Key words: logistics privacy protection, ciphertext policy attribute based encryption (CPABE), blockchain, access rights management
