Protection against Multi-Id Generation Autobots/Botnets Using Using Colored Visually Encoded OTPs Generated by the Random Function in the Spherical Space

Taranpreet Kaur, Harmandeep Singh

Abstract: The one time password are the password valid for only one transaction or login. One time password authentication system protect the IT systems against repeated access, replay attacks, click frauds, etc. The alpha numeric one time passwords are sent to the user end using mobile phone or email. Existing OTPs are prone to the bot attacks, where bot is given access to the mobile phone or email system to auto submit the OTP on the online portal. In this paper, a new graphical password scheme is being proposed to protect against the repeated access, which can be stopped by using the graphical one time password scheme. The dizzy and unreadable graphical one time passwords will be created using colored visually encoded OTPs generated by the random function in the spherical space. The spherical space is having a large number of unique values and later encoded visually using pre-programmed visual encoding for each character being used in the OTP generation. The new graphical OTP will be sent to users end using email, MMS or chatting aps. The proposed system is adaptable to the small-sized to mid-sized online portals requiring the OTP service.
