Protection of Device Screen Information from Shoulder Surfers

Abstract

People use their mobile devices anywhere and anytime to run various applications, and the information displayed on their device screens can be seen by nearby (unauthorized) parties. A shoulder surfer, who is close to the device user, can easily peek at the userÕs device screen. To defend against this threat, we propose to develop a novel system called HideScreen by utilizing the human vision characteristics and optical system properties to hide usersÕ on-screen information from the shoulder surfers. By injecting high frequency patterns into the original information, HideScreen will be able to prevent a shoulder surfer from Òreading/comprehendingÓ the texts/images displayed on the userÕs device screen from the outside of a designed viewing range while allowing the device owner/user to view them without any difficulty. Specifically, HideScreen will use grid patterns on the screen to neutralize the low frequency components so that the on-screen information will Òblend intoÓ the background when viewed from the outside of the designed range. The proposed research consists of (i) development of text/image protection schemes, (ii) development of a screen calibration mechanism, (iii) API implementation, (iv) testing the platform implementation, and (v) evaluation of the protection schemes to be developed.
