Abstract: As an indispensable new resource of modern information society, data always face the risk of being tampered from the beginning. The availability and authenticity of the tampered data will be greatly reduced. And the blockchain technology perfectly meets the requirements of data integrity protection due to its characteristics of anti-tampering, decentralization and single point failure prevention. Firstly, the background of blockchain technology and vital requirements of data protection were briefly described. Secondly, according to the types of blockchain, the existing blockchain data integrity protection achievements were classified and introduced, and the advantages and disadvantages of each achievement were summarized combined with data integrity protection. Thirdly, the current data integrity protection technologies were classified and compared with the blockchain data integrity protection technology, and the shortcomings of the traditional data integrity protection technologies and the advantages of blockchain data integrity protection technology were analyzed. Finally, the defects of blockchain data integrity protection technology were summarized, and the solutions were given.

Key words: blockchain, data security, integrity protection, anti-tamper, decentralization

摘要: 数据作为一种现代信息社会不可或缺的新兴资源,从产生伊始就面临着被各方篡改的风险。遭到篡改的数据在可用性与真实性方面都会大打折扣。而区块链因其不可篡改、去中心化、防止单点故障的特性天然契合数据完整性保护的要求。首先,简述了区块链技术背景与数据保护的核心要求;其次,按照区块链类型将现有区块链数据完整性保护成果进行分类和介绍,并对各成果的优势与不足结合数据完整性保护进行总结;然后,将现有数据完整性保护技术分类并与区块链数据完整性保护技术进行比较,分析传统数据完整性保护技术的不足与区块链数据完整性保护技术的优势;最后,总结区块链数据完整性保护技术的不足之处,并给出解决思路。
