Biometrics Technologies and Applications

摘要

In today's complex, geographically mobile, increasingly electronically wired information society, the problem of verifying an individuals identity continues to pose a great challenge. Conventional technology using Personal Identification Numbers (PIN) or passwords, often in conjunction with plastic cards, is neither convenient nor particularly secure. In the quest for a superior solution, biometrics verification techniques are fast emerging as the most reliable and practical method of individual identity verification. This paper will introduce some main concepts about biometrics (such as why, what, and how), and cover some related biometrics technologies, such as fingerprint, iris, palmprint, voice, signature, face and hand identification, will be briefly reviewed. Some biometrics applications like access control and biometrics smart card are also introduced in this paper. Finally, future works about biometrics are given.
