AbstractThe process of data transfer via the Internet becomes an easy process as a result of the great advances in networking technologies, and now many people can communicate with each other easily and quickly through them.Because the online environment is general and open, the unauthorized one can control information were transmitted between any two parts and interception of getting access for it, because of that there is an emergency need for write covered, which is the science of hiding secret information in a digital cover such as an images, so it is impossible for the normal person and others unauthorized to detected or perceives. In this paper, the technology in the field of information hiding in the images is developed, where first, the cover (PNG, BMP) image is segmented using Chan-Vese algorithm, then the text will hide in the segmented image depending on the areas of clipping.The standards (PSNR, BER) are used to measure technical efficiency. In addition the algorithm of this technique is implemented in Matlab.
