An effective locking scheme of smart multimedia devices with convenience and enhanced security

Abstract

The touch screen, the fruit of recent IT development, is incorporated into many applications through a variety of touch screen smart multimedia devices (e.g., digital cameras, TVs, door-lock systems, smart phones, tablet PCs and so on). For smart multimedia devices, it provides convenient use of time and space for many people by replacing many desktop PC functions. Although this convenience has gained popularity among the public, the security is usually neglected. In addition, the miniaturization of smart devices provides easy portability, but it also leads to more chances of being lost or stolen. Inherent features are generalized, but the features also increase risk of exposing personal information. As a result, smart multimedia devices provide a variety of locking features to protect personal information. The features include simple hiding of the screen, password buttons, and pattern locks. Although password and pattern lock features exhibit some degree of security, they are vulnerable to shoulder surfing or smudging. In this paper, vulnerable security points of smart multimedia devices are complemented and the locking system for enhanced security (LSES), in which intuitive user interface provides convenience, is proposed. LSES reduces exposure risk factors with various input methods for the lock pattern.
