摘要：

合法用户的身份认证在信息安全中起着非常重要的作用，以静态口令为基础的传统认证方式正面临多种安全隐患。基于视觉密码技术的原理和特点，从使用安全性方面提出改进算法，实现了一套完整的一次一密身份口令认证方案，使得认证过程更加安全可靠。系统采用双因素认证方式，将指纹识别技术和视觉密码技术相结合，进一步提高安全性，并最终在AM3517实验平台上实现。实测表明，该系统操作简单、认证过程安全可靠、易扩展、使用成本低，具有广阔的应用前景。

Abstract:

The identity authentication for legal users is very important in information security. Authentication method based on traditional static password faces many security risks. This system is based on the features and advantages of visual cryptography. By using an improved algorithm from the practical safety, we achieve a complete set of onetime pad password authentication scheme and make the process of authentication safer and more reliable. The system adopts twofactor authentication method. By combining the fingerprint method and the visual cryptography method, the security is further improved. Finally, we realize an integrated system on the experimenter baseboard of AM3517. Experiment shows that the system is easy in operation and low cost in use, safe in identity authentication and can be extended easily. It will have broad applications in the near future.
