摘要
电子证据作为八大类证据之一,在司法活动中占据越来越重要的地位,而电子证据的易复制、易损坏和易篡改等特点,导致其公信力相对不高。在研究区块链和星际文件系统的基础上,提出一种基于区块链与星际文件系统的电子证据存证模型,加密技术实现对电子证据的加密,星际文件系统实现电子证据的分布式存储,区块链存储电子证据的哈希值、关键词和在星际文件系统中的分片位置索引,同时在区块链上实现电子证据的搜索与验证。该存证模型确保电子证据的机密性与完整性,并实现对电子证据的授权访问,因此对于提高电子证据的公信力有一定的现实意义。
As one of the eight types of evidence,electronic evidence is playing an increasingly important role in judicial activities,but the characteristics of electronic evidence such as easy copying,damage and tampering lead to relatively low credibility of electronic evidence.Based on the research of blockchain and interplanetary file system(IPFS),an electronic evidence storage and certification model based on blockchain and IPFS is proposed.The encryption technology realizes the encryption of electronic evidence,and IPFS realizes the distributed storage of electronic evidence,the blockchain stores the hash value of the electronic evidence,keywords and the index of the segment location in IPFS,and at the same time realizes the search and verification of the electronic evidence on the blockchain.The evidence Storage and certification model ensures the confidentiality and integrity of electronic evidence,and realizes authorized access to electronic evidence,so it has certain practical significance for improving the credibility of electronic evidence.
