可靠的身份认证是保证信息系统安全的第一道防线,生物认证技术的出现为保护信息系统的安全提供了一种更可靠安全的方法。该文先分析一个通用生物认证系统结构参考模型,然后详细分析要设计一个完整的生物认证系统必须考虑的主要因素,并给出一个已经实现的生物认证系统设计实例。
Reliable authentication is the first line of defense to ensure the security of information systems. The emergence of biometric authentication technology provides a more reliable and secure method for the security of information systems. This paper first analyzes a generic biometric authentication system structure reference model, then analyzes in detail the main factors which must be considered when designing a complete biometric authentication system and gives an example of the design of a biometric authentication system that has been implemented.
