Authentication is the action or a process to check the identity of the user to use or access any system, profile, database, etc. Today, in the era of advanced technologies, user strongly needs a flexible, easy to remember and secured authentication scheme to protect the privacy of user’s data. The main problem faced by a user is password remembrance because textual password becomes more complex nowadays since it contains alphabets, numbers and symbols. So, now it’s the time to move on with image passwords which can be easily remembered by the user. But the implementation of an image password is not an easy job since it consumes a large amount of memory and time. This paper focuses on the well-known techniques that are used in image authentication schemes. It also explains the architecture and workflow of all those schemes which makes the image authentication scheme advantageous as well as acceptable in today’s digital era.
