BIOMETRICS BASED IDENTIFICATION TECHNIQUES (BIT)

[摘要] A large number of systems require the reliable and efficient personal recognition methods to either confirm/determine (authenticate) the identity of an individual that requesting their services. Purpose of such type of methods is to ensure that rendered services are accessed only by a authenticate user and no one else. In biometric recognition, biometrics refers automatic recognition/authentication of individual totally based on their physiological and behavioral properties. By using biometrics, it’s possible that to confirm/establish an individual’s identity based on “who he is,” rather than by “what he possesses” (e.g. ID card) “what he remembers” (e.g. password). In this paper, we give a brief overview of the field of biometrics and summarize some biometric identification techniques with their strengths, limitations, and related privacy concerns and comparisons with each other.
