Log security evidence storage method and device, electronic equipment and storage medium

The invention relates to a log security evidence storage method and device, electronic equipment and a storage medium. The log security evidence storage method is applied to the technical field of artificial intelligence and comprises the steps of obtaining original log data; determining target log data with a network attack in the original log data; encrypting the target log data to obtain encrypted log data; and uploading the encrypted log data to a block chain. The method solves the following problems that in the related technology, a database, distributed storage or disk redundancy technology is adopted to store log data, after the log data is subjected to source tracing and evidence obtaining, the log data is still stored in the original position, and it cannot be guaranteed that the log data for recording evidence is not forged or damaged. 本申请涉及一种日志安全存证方法、装置、电子设备及存储介质。应用于人工智能技术领域，其中，日志安全存证方法包括：获取原始日志数据；确定所述原始日志数据中发生网络攻击的目标日志数据；对所述目标日志数据进行加密，得到加密日志数据；将所述加密日志数据上传至区块链。以解决相关技术中，采用数据库、分布式存储或者磁盘冗余技术对日志数据进行存储，
