Abstract

Nowadays, traditional authentication methods are vulnerable to face attacks that are often based on inherent security issues. Professional attackers leverage adversarial offenses on the security holes. Biometrics has intrinsic advantages to overcome the traditional authentication methods on security, success rates, efficiency, and accessibility. Biometrics has wide prospects to implement various applications in fields. Whether in authentication security or clinical medicine, biometrics is one of the mainstream studies. In this paper, we surveyed and reviewed some related studies of biometrics, which are outstanding and significant in driving the development and popularization of biometrics. Although they still have some inherent disadvantages to restrict popularization, these obstacles could not conceal the promising future of biometrics. Multi-factors continuous biometrics authentication has become the mainstream trend of development. We reflect the findings as well as the challenges of the studies in the survey paper.
