ABSTRACTThis paper proposes a new data-hidingmethod based on pixel pair matching (PPM).The basic idea of PPM is to use the values ofpixel pair as a reference coordinate, andsearch a coordinate in the neighborhood set ofthis pixel pair according to a given messagedigit.
The pixel pair is then replaced by the searchedcoordinate to conceal the digit. Exploiting modification direction (EMD) anddiamond encoding (DE) are two data-hidingmethods proposed recently based on PPM. The maximum capacity of EMD is 1.161 bppand DE extends the payload of EMD byembedding digits in a larger notational system.
The proposed method offers lower distortion than DE byproviding more compact neighborhood sets and allowingembedded digits in any notational system. Compared with the optimal pixel adjustment process(OPAP) method, the proposed method always has lowerdistortion for various payloads.Experimental results reveal that the proposed method notonly provides better performance than those of OPAP andDE, but also is secure under the detection of some well-known steganalysis techniques.
OBJECTIVE This project is a data hiding method based on PPM.. Exploiting modification direction (EMD) and diamond encoding (DE) are two data- hiding methods proposed based on PPM.

EXISTING SYSTEM: Least significant bit substitution method. This method is easy to implement with low CPU cost.
DISADVANTAGES OF EXISTING SYSTEM: Imbalanced embedding distortion emerges and is vulnerable to steganalysis. The existing technique can be easily cracked.
