Pictorial Sequence Authentication Using Optimized Disarray System

Authentication is a fundamental trust to any trust oriented computational frameworks and furthermore a basic part in numerous security protocols. This paper gives other option to conventional security inquires and OTP. They are attractive since people usually remember pictures. In this paper, we propose a sample sequence of pictorial authentication system and detriments in using OTP. Authentication like OTP needs handy mobile device with subscribed number in it and needs a network to send it. In such case of network failure or damage in mobile phones then the OTP could not be sent. It takes a time delay for accessing money transaction or any kind of online payments. The proposed optimized chaotic system uses different mapping techniques wherein the pictorial authentication method relies on the user's ability to recognize pre-chosen categories from a grid of pictures. This system coordinates image based confirmation and to overcome the OTP weaknesses where we can accomplish abnormal state of security in validating the client over the web with effective time synchronization.
