One of the most important issues in information security today is user authentication. There is good security when using text based strong password schemes, but often memorizing the password is so difficult and users write them on a piece of paper or store it inside the computer. There is an alternative to text-based authentication that is GUA (Graphical User Authentication) or simply Graphical Password based on the fact that humans tend to remember images better. This type of interface provides an easy to create and remember passwords for users. However, one big problem that is plaguing GUA is the shoulder surfing attack that can capture user mouse clicks and gallery attack images that can change gallery images with physical attack. In this article, we propose a new algorithm that uses the watermarking technique as a solution to solve image gallery attacks and the use of random character sets for each image to resist surfing shoulder attacks to provide a Better system security. All images of information in the registration phase will be processed by the protection of water copy rights where the login page will verify this information for security reasons.
