    Abstract: We propose an information hiding technique which based on pixels’ block. We used pixels contractive relation to hide the information that we want to embed. The characteristic of our method is that to use pixels contractive relation to assist lossy compression process in reducing the image size. There exists many hiding techniques, but most of the techniques cannot tolerate the destruction of lossy compression. Compression will speed up the transmission of the image with the hiding data.We achieve something others cannot do, to implement compression into the transmission of images in order to speed up the process. Besides, in our method it is easy to hide and extract the hiding data when implemented.We show that our method can extract the data efficiently and correctly, even with JPEG (Joint Picture Expert Group) compression. Our proposed technique tallies with the transmitted image on the Internet and it is a secure and efficient method.
