Design of supervised anonymous identity authentication scheme in blockchain-based elderly data auditing system
In allusion to some privacy protection problems in the practical application of data audit system,such as data disclosure,data damage and the disclosure of the identity of third-party auditors,an elderly data audit system based on blockchain is designed,and on this basis,a supervised anonymous identity authentication scheme is designed.In this system,the asymmetric encryption algorithm and group signature algorithm are used to ensure the security of data communication and data storage,and achieve the anonymity of identity certificates,which has a certain ability of privacy protection.In addition,if the third-party auditors have illegal behavior,the true identity information of the third-party auditors can be obtained from the identity certificate.
