近年来，生物特征的安全性问题已成为一个重要的研究领域。虽然正在部署基于虹膜识别、DNA分析和指纹识别的系统，但在某些情况下，仅靠这些系统无法提供万无一失的安全性。从信息理论的角度来看，生物特征安全提供了一个国家的最先进的生物特征安全系统的概述。使用信息理论技术，它讨论了一些最有前途的方法，以提供实用，但安全的系统。从信息理论的角度来看，生物特征安全研究了一些问题，涉及到设计的生物特征保密系统的认证和识别。首先，它回顾了秘密共享的问题，以便为随后讨论的秘密密钥速率和隐私泄漏的生物特征保密系统的理论基础。在详细描述生物特征识别技术之前，使用离散和高斯生物特征源深入讨论生物特征认证系统。由于生物特征数据通常用于身份识别和认证目的，因此确定了身份识别、密钥和隐私泄露率之间的权衡。最后，实际考虑处理。分析了具有选定密钥的二进制生物认证系统的实现，称为模糊承诺。该专着的结论是调查如何二进制量化的生物特征序列的影响性能的生物特征保密系统的秘密密钥速率和隐私泄漏。从信息理论的角度来看，生物识别安全是一个深入的审查的主题，这给读者一个很好的起点，为进一步的研究。
The issue of biometric security has become a major research area recently. While systems based on iris-recognition, DNA analysis and fingerprinting are being deployed, there are instances where these alone cannot provide fool-proof security. Biometric Security from an Information-Theoretical Perspective provides an overview of the state-of-the-art of biometric security systems. Using information theoretic techniques it discusses some of the most promising methods to provide practical, but safe, systems. Biometric Security from an Information-Theoretical Perspective studies a number of problems related to the design of biometric secrecy systems for both authentication and identification. First, it reviews the problem of secret sharing in order to set theoretical grounds for the subsequent discussion of secret-key rates and privacy leakage in biometric secrecy systems. Biometric authentication systems are discussed in depth using discrete and Gaussian biometric sources, before describing biometric identification techniques in detail. Since biometric data are typically used for both identification and authentication purposes, the trade-off between identification, secret-key and privacy-leakage rates are determined. Finally, practical considerations are treated. The realization of binary biometric authentication systems with chosen secret keys, called fuzzy commitment, is analyzed. The monograph concludes by investigating how binary quantization of biometric sequences influences the performance of biometric secrecy systems with respect to secret-key rates and privacy leakage. Biometric Security from an Information-Theoretical Perspective is an in-depth review of the topic, which gives the reader an excellent starting point for further research.
