color images Steganography via text message compression

In this paper, an image Steganography algorithm based on text message concealment compression is presented. In this proposed method, at the same time, the level of security and capacity in Steganography color images has been increased. The structure of the proposed method consists of two parts: transmitter (lathe) and receiver (lathe). In Steganography, the number of bits of the message is first reduced and compressed as much as possible by converting the text message into binary information and using appropriate coding to increase the capacity of the information to be embedded in the host image. In order to improve the capacity to insert a hidden message, the host signal uses a binary tree search algorithm to compress and expand the text message before inserting and extracting it into the image, and at the same time generates cryptographic keys. In order to evaluate the performance of the proposed design, criteria such as Peak signal-to-noise ratio (PSNR), hiding ratio (HR)bit error rate (BER), similarity level of hidden and extracted messages (SIM) as well as algorithm execution speed, Used. By comparing the performance of the proposed algorithm with other proposed algorithms, it shows the optimal performance of the proposed design.
