摘要：Here we proposed a new data-hiding method based on pixel pair matching (PPM). in this paper The basicidea of PPM is to use the values of pixel pair as a reference coordinate, and coordinate search in the neighborhood used toset of this pixel pair according to a given message digit. The pixel pair is then replaced by the searched coordinate toconceal the digit.(EMD)exploitedmodificationdirection(EMD) and diamond encoding (DE) are two data-hiding methodsproposed recently based on PPM. then The maximum capacity of EMD is 1.161 bpp and DE extends the payload of EMDby embedding digits in a larger notational system.this is the proposed method offers lower distortion than DE by havinghigh compact neighborhood sets and it will also accepting embedded digits in any representative system. then it will beCompared with the (OPAP)optimal pixel adjustment process method, then this method always has lower distortion forvarious payloads. Experimental results reveal that the proposed method does not only provides performance better thanthose of OPAP and DE, but also is secure under the detection of some well-known steganalysis techniques
