Data Embedding and Extracting Using Pixel Pair Matching With Potential Masking

Rasiyath

Abstract :

This paper presents a new data–hiding method based on pixel pair matching (PPM). The basic idea of PPM is to use the values of pixel pair as a reference coordinate, and search a coordinate in the neighborhood set of this pixel pair according to a given message digit. The pixel pair is then replaced by the searched coordinate to conceal the digit.Here introduces a new term called potential masking. This is proposed to be done before the embedding process. Potential masking is done based on frequency of pixels in Wavelet domain. Exploiting modification direction (EMD) and diamond encoding (DE) are two data–hiding method proposed recently based on PPM.The proposed method offers lower distortion and allowing embedded digits in any notational system. The proposed method always has lower distortion for various payloads and the experimental results reveal that it is secure under the detection of some well–known steganalysis techniques.
