Image password authentication on a website / Nur Izzati Ishak

Human factors are often considered the weakest link in a computer security system. If we point out that there are three major areas where human-computer interaction is important: security operations, developing secure systems, authentication. We focus on the authentication problem here. User authentication is a fundamental component in most computer security contexts. Studies about passwords show that user can only remember a limited number of passwords, they tend to note them down somewhere or will use the same/similar passwords for different accounts. Authentication is performed using passwords that are alphanumeric in nature. The problem is the users find it difficult in remembering a password that is long and needs to be recalled again and again while implementing it. In addition, text-based passwords are easy to crack by intruders. To lessen the problems, this work proposed image password for authentication. However, Knowledge Based Techniques are the most widely used authentication techniques that include text-based and picture-based password. The recognition-based graphical techniques are one of the techniques of picture-based passwords. Using recognition-based graphical techniques, a user is presented with a set of images and the user passes the authentication by recognizing and identifying the images his/her selected during the registration stage. The user will upload the image/set of images along with all his/her details during the time of the registration. Then the image selected by the user will appear on the next page.
