A HIGH CAPACITIVE EMD TECHNIQUE FOR WET IMAGE
Journal Title: Scientific Bulletin, Series: Electronics and Computer Science - Year 2014, Vol 14, Issue 1
Abstract
Exploiting Modification Direction (EMD) is a technique to hide secret data into digital images whereas wet paper coding is a technique for hiding data into specific pixels called dry pixels. In our scheme, we combined both the techniques. Before embedding, we classify image pixels into wet and dry pixels using location mapper that is shared between sender and receiver and then we embed secret data on each dry pixel using EMD technique. The experimental results show that our scheme provides high embedding capacity as compared to the earlier techniques.
