Abstract

In order to prevent intruders from looking into sensitive data in smartphones users will have their own security measures, but those security measures are traditionally available measures one among them is finger based pattern doodling which became quite popular among users, also studies show that it is easy to remember and use than alphanumeric text based passwords. But these patterns are static in nature which can be stolen using shoulder-surfing attack. Shoulder-surfing refers to attack which is made based on observation of attacker either directly, or indirectly using applications to record such as camera or key logger. In this paper we have introduced a concept of dynamic patterns which when user records his input for the first time the positions will remain same but the next time the positions of each pattern is changed dynamically, also there is one more concept called image falsification is used. Image Falsification means deceiving the attacker to the false image pattern instead of exposing the true image pattern and the true pattern remains known only to the user. C. Asvin Parthasarathy | R.
