Abstract
Information security, the practice to protect information from unauthorized use, attracts researchers attention. In this paper, we proposed a visual masking effect based perceptual information protection scheme for display devices, such as mobile device, personal computer and ATM machine. The private information is embedded into the misleading image with the proposed algorithm, resulting in a dramatic descent in perceptual saliency of the private information for peepers viewing with naked eyes, while maintaining accessibility for authorized viewers wearing color filter. Quantitative and qualitative experiments are conducted, and results show effectiveness of our algorithm.
