Effective Data Hiding Method Through Pixel Pair Matching
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 11
Abstract
This work proposes a new data-hiding method based on pixel pair matching , which is to use the values of pixel pair as a reference coordinate, and find a coordinate in the neighborhood set of this pixel pair based on the given message. Further the pixel pair is replaced by the searched coordinate to cover the digit. Two methods has been proposed to overcome this problem one is Exploiting modification direction (EMD) and another is diamond encoding (DE). The proposed methods offer lower distortion as compared to the existing methods by providing more compact neighborhood sets and allowing embedded digits in any notational system.
