针对WEB 云存储系统现有"静态口令+实时数据”的身份认证模式存在安全性能较低的问题，设计了基于指纹 识别技术的身份认证系统。该设计方案采用指纹识别的认证模式对云存储用户进行身份认证，提高了身份认证的安全性、可 靠性，解决了云存储用户账号非法访问、篡改等问题。提出了基于对称加密算法、非对称加密算法的混合加密算法，并将其作 为身份认证协议，有效提高了认证的效率，实现了海量数据的高效传输。实验结果表明，该方案在云存储身份认证系统中得到 很好的应用。

For the lower safety problem in the "static password + real-time data" authentication modes of WEB cloud storage system, this paper designs an authentication system based on fingerprint identification technology. It uses the authentication model based on fingerprint identification for user identity authentication, improving the authentication security and reliability, and solving the issues of user account illegal access and tampering. It proposes the hybrid encryption algorithm based on symmetric encryption algorithm and asymmetric encryption algorithm which is used as a identity authentication protocol. This method effectively improves the certification efficiency, and realizes the effective transmission of huge amounts of data. The experimental results show that the scheme obtains very good application in the cloud storage identity authentication system.
