The one time passwords (OTPs) are widely used in
the various application to protect the bot or autobot from
repeated access without human interaction to the online portals.
The OTPs are usually sent over the mobile phone numbers, from
where the user read, fill and submit the one time password, which
is later verified on the server side and the next step is taken
according to the requirement. These message based OTPs are
prone to the various autobot/bot based repeated access attacks
because it is easier to read the message automatically fromt the
phone. Also it can be easily submitted using automatic form
submission script. In this paper, we have proposed a new image
based OTP which can be sent to the user's phone using MMS or
various other social or chatting applications. The image based
OTP provides more harden protection from the bot/autobot. than
the ordinary text-based OTPs. The OTP is generated using the
elevation angle and azimuth angle followed by radius value
matrix, which provides a robust environment to generate the
unique OTP every time. The OTP is the converted into the image
using ASCII character identity based visual encoding which will
be forwarded to the user later. The new technique can be used on
various web portals require OTP on service.
