Abstract
In this paper, we proposed a joint lossless index coding and data hiding technique for the palette images. The palette image is the compressed image of the color image quantization technique. The compressed codes of the palette image consist of the index table and the color palette. In the proposed technique, a three-category lossless index coding method is employed. The secret data is embedded into the encoded index table during the index coding process is executed. From the results, it is shown that good hiding capacity is obtained in the proposed technique while keeping a good bit rate.
