Popis: User authentication is a fundamental component in most computer security context. In recent years, computer and network security has been formulated as a technical problem. A key area in security research is authentication which is the determination of whether a user should be allowed access to a given system or resource. In this respect, Authentication is a process by which a system verifies the identity of a user. Authentication may also be generalized by saying that “to authenticate” means “to authorize”. Users tend to pick passwords that can be easily guessed, on the other hand, if a password is hard to guess, then it is often hard to remember. To address this problem some researchers have developed authentication methods that use pictures as passwords, known as graphical passwords.Graphical passwords are a proposed alternative to text passwords that have been shown to have good usability and security properties that use images for login, and leverage the picture superiority effect for good usability and memorability. Categories of graphical passwords have been distinguished on the basis of different kinds of memory retrieval (recall, cued-recall, and recognition). Though there are several kinds of graphical password, But We have choose to implement the cued click based due to efficient and more secured, Cued click points is a click-based graphical password scheme, Users click on one point per image for a sequence of images. The next image is based on the previous clickpoint. Performance was very good in terms of speed, accuracy, and number of errors. Graphical passwords may offer better security than text-based passwords because many people, in an attempt to memorize text-based passwords, use plain words rather than the recommended jumble of characters.
