چکیده
The project proposes the data hiding technique using adaptive pixel pair matching (PPM) and LSB Replacement for secret data communication. The basic idea in LSB is the direct replacement of LSBs of pixel bits of the cover image with the secret message bits. 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 proposed method always has lower distortion for various payloads Compared with the LSB and optimal pixel adjustment process (OPAP) method. Finally project prove that the proposed method provides better performance than those of LSB and OPAP.This method is more secure and it yields the better signal to noise ratio for preserving the image qualityI.
