Abstract
User authentication is the process of confirming one's identity by checking one's credentials. It is a cornerstone of information security. Traditionally, users access information systems by applying something they know, such as passwords, or something they possess, such as tokens. A third method, biometrics is based on something users are, such as fingerprints. Nowadays to protect sensitive information, these methods are deployed together to form a strong three-fact authentication. This report presents an overview of different authentication factors, analyzes their advantages and disadvantages, and indicates the common problems facing each factor. Since there are various biometric technologies, each with its own strengths and weaknesses, this report discusses only the most popular biometric technologies in detail. The purpose of this report is to position biometrics in user authentication to enhance information security. As a result, a system architecture is presented to provide a solution for information protection in secure or sensitive environments.
