Biometrics

Abstract

It is important to know that absolute security does not exist, and the main goal of the security system is to reach an optimal approach that satisfies the customer requirements. Biometrics is a small part of the security system that aims to replace a traditional password or a key. Biometrics offer higher security levels by simply ensuring that only the authorized people have access to sensitive data. It is easy to copy or get a traditional password using different methods (legal or illegal), but it is difficult to copy a key of biometric pattern such as iris or fingerprint or other patterns. Recent years have seen a boom in the use of biometric techniques in the design of modern equipment to maintain the information and personal identification. This chapter focuses on biometrics (types and technologies), personal identification, and specifications, and then how to implement these performances in security. Finally, a future aspect of merging technologies and disciplines is a good issue to treat via a specific concentration of information technology. In this chapter, two approached are proposed: a novel thinning algorithm for fingerprint recognition and a novel e-passport based on personal identification.
