Abstract : This paper focuses on the design of a novel Reversible Data Hiding Scheme using Enhanced Difference Pair Mapping which aims at higher embedding performance. Difference Pair Mapping is developed on the difference of pixel pair values in an image. Each pixel value is modeled in a context based approach using Gradient Edge Detection Predictor. The proposed approach uses run length coding to compress and decompress the location map of the specified image which indicates location for data embedding. The lossless address generation and address recovery scheme is accomplished using run length coding. The experimental evaluation of the proposed method is simulated in Matlab 2013a. The results indicate improvement in embedding capacity with better image quality as compared to current existing techniques. © Research India Publications.
