A Region Boundaries Algorithm for Ear Authentication Based on Plots

Ear recognition methods in image processing become a key issue in ear identification and analysis for many geometric applications. Actually, the Captcha as graphical password methods like click text, click animal, and animal grid are used to provide authentication web applications. These methods results to security attacks. So, ear recognition methods are helpful when a RBA, converts the original image to inverted binary image to plot the boundaries of the ear. The obtained image, shows the plots like circles, Rectangular, and Squares. This paper hence proposed an RBA method, which provides more Authentication than CaRp method.
