This paper introduces a new encrypted data hiding method based on Adaptive Pixel Pair Matching and RSA encryption algorithm. The basic idea of Pixel Pair Matching is to use the values of pixel pair as a reference coordinate, and search a coordinate in the neighbourhood 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. The text data to be hidden undergoes a pre-processing step which encrypts the data using RSA encryption before it is embedded into the cover image.
