摘要/Abstract

摘要：

信息数字化的快速发展,大量司法证据电子化也带来了很多数据的安全、信任等问题。传统的存证方式在面对不断增长的电子数据存证需求时,逐渐地显露出成本高、效率低以及采信困难等不足,确保视频证据、语音记录、电子合同等电子司法证据的安全、可信逐渐成为一个必须解决的问题。针对上述问题,本文设计了一种基于超级账本技术的区块链电子存证系统,通过区块链的共识验证机制与星际文件系统结合,使得电子证据安全可信以及责任可追溯的同时,解决了电子证据的存储问题。最后,设计了访问权限控制方案,保证了用户数据的隐私。

Abstract:

With the rapid development of information digitization, a great deal of judicial evidence electronization also brings a lot of issues such as data security and trust. To face the growing demand for electronic data storage, the traditional method of depositing has gradually revealed its shortcomings, such as high cost, low efficiency, and difficulty in obtaining credit, so how to ensure the security and credibility of video evidence, voice recording, electronic contract, and other electronic judicial evidence has become a problem that must be solved. In order to solve these problems, this paper designs a blockchain electronic certificate storage system based on the Hyperledger Fabric. Through the combination of the blockchain consensus mechanism and the interstellar file system, the electronic evidence storage problem is solved while ensuring the safety and credibility of the electronic evidence and the traceability of responsibilities. Finally, an access permission control scheme is designed to ensure the privacy of user data.

Key words: blockchain, hyperledger fabric, electronic evidence storage
