SECRET MESSAGE ENCODED BY EBCDIC IN MULTIPLE DCT FOR TWO COVERS

Author

Abstract
This paper suggest a proposed algorithm to hide message encoded using "EBCDIC" in multiform DCT's coefficients for two images. The DCT has the property that, for a typical image, most of the visually significant information about the image is concentrated in just a few coefficients of the DCT. Notice that most of the energy is in the upper left corner. Hiding message can be obtained without use original image with high quality. The experiments for embedding and extracting was successfully simulated by MATLAB.
