Abstract
Image compression techniques such as Vector Quantization(VQ), Block Truncation Coding(BTC) and their hybrid methods, are widely used in many applications. Hiding secret data in image compression codes becomes necessary and attractive. In this paper, a data hiding approach in block truncation coding is presented. The proposed method hides secret data in compressed images by modifying the bitmaps generated from BTC. Simulation results illustrate that the visual quality of the stego-images are relatively good. The distortion between the original BTC image and stego-image is insignificant.
