摘　　要：目前征信个人隐私保护系统中的消息转移只实现了单向信任转移,对申请方的责任未做确认,因此,无法建立消息转移双方的双向信任关系,无法实现公正性;此外,消息转移过程也存在安全隐患。提出一个基于区块链的征信系统消息转移协议,该协议要求消息转移的双方需要完成顺序的签署确认,借助于区块链的共识机制和附加协议、加密算法等技术保障消息安全转移,具有公正性、隐私性。此外,还提供了消息的追加、更新和删除等功能。最后,分析了本协议的公正性、隐私性和不可抵赖性。At present,the message transfer in the personal privacy protection system of credit investigation only realizes the one-way trust transfer,and the responsibility of the applicant has not been confirmed.Therefore,it is impossible to establish the two-way trust relationship between the two parties of message transfer and realize impartiality.In addition,the message transfer process has security implications.Therefore,this paper proposes a credit system message transfer protocol based on blockchain.This protocol required both parties of message transfer to complete the signature and confirmation of sequence,and ensured the secure transfer of messages with impartiality and privacy by means of the consensus mechanism of blockchain,additional protocol,encryption algorithm and other technologies.In addition,it provided functions such as append,update and delete messages.The fairness,privacy and non-repudiation of this agreement were analyzed.
