摘　　要：云存储有效解决了存储性能瓶颈,同时带来了数据安全和隐私保护难题。为了解决这一问题,提出了一种基于指纹魔方算法的云存储数据保护机制。该机制通过用户的指纹特征值控制魔方旋转对文件进行加密,再利用门限分割技术将文件分割成小块存储到各个服务器中。需要恢复原文件时,先对各个服务器中的文件块进行完整性验证,找到不少于门限值数量的文件块就能完整恢复文件。该机制保护了云存储用户的隐私数据,同时提高了云存储系统的抗破坏能力和灵活性。Cloud storage is an effective solution to the storage performance bottleneck, but it also gives rise to problems of data security and privacy protection. In order to solve this problem, a cloud storage data protection mechanism based on a fingerprint cube algorithm was developed. Mechanism through the user＇s fingerprint characteristic value control cube rotation to encrypt files, and then use threshold segmentation technique to split the file into small blocks to each storage server. If it is expected to restore the original file, check the integrity of each block at first, and then find no less than the threshold number of file blocks, which leads to recover the full document. The mechanism protects the privacy of user data stored in the cloud, but also improve the anti-destruction capability and flexibility of cloud storage system.
