摘要
传统公证业务中存在信息流通受限、数据易丢失和易被篡改等问题,为司法取证等工作带来不便.研究和设计的公证信息可信存储系统利用Hyperledger组件将公证处设为联盟节点,将公证过程中的关键数据计算为哈希摘要后上传,并可信存储到联盟链中以供查询,同时支持不同公证处对数据的细粒度访问权限控制.此外,实现公证数据全生命周期管理的功能,将用户对公证数据的全部操作记录在链上,为公证数据在业务流转过程中的操作监管提供支持.实验测试结果与分析表明,系统功能设计合理且性能良好.
Abstract
In the traditional notarization service,there are problems such as poor information flow,easy data loss and difficult verification after data tampering,which brings inconvenience to judicial evidence collection and other work.Trusted notarial information storage system based on the consortium blockchain is designed.It set notarization to alliance node using Hyperledger components,calculated the Hash abstract of the key data involved in the process of notarization,uploaded them and stored in the consortium blockchain for data query,and supported the fine-grained access control of notarial data by different notarization.In addition,the system realized full life cycle management of notarial data,recorded all users'operations of notarial data on the blockchain,and provided support for the operation supervision of notarial data in the whole process of business circulation.The experimental results and analysis show that the system has reasonable design of functions and good performance.
