摘　　要：为了实现数据供需双方安全地共享隐私信息,并确保双方无须交互用户标识信息,提出一种基于标识密码算法实现的隐私信息共享技术。标识密码算法是以使用人拥有的有效且唯一标识作为公钥,用户无须申请和交换证书,即可实现交互双方的认证、秘密信息传输等功能。经实践验证,这一技术能够有效实现隐私信息的安全共享,同时能够使数据供方无法知晓数据需方待查的用户标识信息,从而达到实现数据供需双方隐私信息共享的目的。In order to implement the secure sharing of privacy information between the data supplier and the data supplier,and toensure that both parties do not need to exchange user identity information,a privacy information sharing technology based on identity cryptography algorithm is proposed.The identity cryptographic algorithm takes the user's valid and unique identity as the publickey,and users can realize the functions of authentication and secret information transmission without applying for and exchangingcertificates.The practice shows that this technology can effectively achieve the safe sharing of privacy information,and make thedata supplier unable to know the user identification information of the data demander,so as to achieve the purpose of sharing privacy information between the data demander and the demander.
