Compression Text by Coding and Hiding in Color Image

Abstract

Recently, serious and enormous security challenges have led to the creation of new and secure ways to transfer data and reduce the opportunity for hackers to use their methods to analyze confidential information between the two parties. Therefore, data security and protection is one of the most used technologies in the field of computer science, because of its great importance in all fields, whether political, economic, or military. The main goal of this paper is to develop and design a systematic, effective and secure method for transferring data, in addition to reducing the time and cost when sending data over the Internet. Therefore, an intelligent (hybrid) system was proposed in this paper that combines firstly compression of data by using coding method to reduce the amount of data sent and helps in fast transfer while using slow Internet or taking up small disk space. Secondly encryption compressed data based on XOR encryption technology with random key generated from text  and  finally hiding bits sets in cover RGB image using the LSB method to implant parts of the compressed text into the cover image. Good results were obtained for PSNR image measurements, and thus the proposed technique provided high-level concealment and security capabilities.
