Summary
The first level is the image ordering which
simply means the selection of previously set images in the same order. From a
sequence of images, the user can select few images at random. The images
provided are commonly used, user friendly and easy to remember images. The
maximum limit of image selection will be set to three images. During
authentication phase, the sequence of images will be given in a shuffled order,
from which the user selects the same set of images chosen during registration
phase in the same order. In case of any invalid selection of images, the system
will be locked automatically after few trials based on the count given. After
image ordering, the second level is the selection of color pixels. The user can
select a single color pixel from the different blocks of colors provided. The
maximum limit of color pixel selection will be set to one. During
authentication phase, the previously set images should be chosen in the first
level and then the user will be redirected to the second level i.e. the color
pixel selection, where the user selects the same colour pixel chosen in the
registration phase. In case of any invalid selection of images or colour pixel
the system will be locked automatically after few trials based on the count
given. In the Third level, one time password (OTP) technique is used that is a
password which is valid for a single session. OTP will securely be generated
and verify using Smartphone. The major advantage of the system is that,
different OTP is generated each time the user tries to login.
