An Information Hiding Scheme Based on Pixel-Value-Ordering and Prediction-Error Expansion with Reversibility

Author 1: Ching Chiuan Lin Author 2: Shih-Chieh Chen Author 3: Kuo Feng Hwang

This paper proposes a data hiding scheme based on pixel-value-ordering and predication-error expansion. In a natural image, most neighboring pixels have similar pixel values, i.e. the difference between neighboring pixels is small. Based on the observation, we may predict a pixel’s value according its neighboring pixels. The proposed scheme divides… Read full abstract & cite →
