Tag Association Based Graphical Password Using Image Feature Matching
Description
Much work on graphical password has been proposed in order to realize easier and more secure authentication with use of images as a password rather than text based passwords. We have proposed a Tag Association Based graphical password called TAB. In TAB, a set of images which are presented to a user is determined among a large collection in image search or sharing web services using user pre-registered pass-terms, while the typical graphical password presents a user a set of images including one of the user pre-registered images. In our demo, we present the novel prototype system with an extension of TAB. The extended TAB is incorporated a well-known image recognition algorithm, such as SIFT (Scale Invariant Feature Transform) or SURF (Speeded Up Robust Feature) in order to increase both Shoulder Surfing Unsuccess and Authentication Success Ratios.
