This research presents a new technique for hiding any image of a large size in pictures and studying that fit the size of the image to be hidden with the pictures to be hidden in it and this was not found in the previously studied methods, where the image to be transferred was cut into several pieces and then stored each part in an image Where multiple photos are chosen for the match, the added information for the image to be portrayed represents the image, its suffix, and its size, as well as the number of each piece. Here some inquiries appear: do we want to encode the part to be tuned for, that is why the RES algorithm has been implemented for coding, and do we want to compress the part that needs to be tuned for that the Huffman Algorithm has been applied to compression. Depending on the confidentiality of the information to be encoded, encryption can be selected or not, and according to the size of the data of the part to be transcribed, compsess can be selected or not. Datas were cut into Blokes, and to make sure the data was not changed, the digital signature was used. Then, I applied the LSB (Significant Bit Least) binary cell algorithm. To obtain better results, the whale algorithm was used to determine the optimal position for escaping in any form.
The effectiveness of the proposed algorithm comes from obtaining the optimal value of PSNR (Peak Signal to Noise Ratio) by determining the best location for the match, as well as the value of the mean square error MSE (Mean Square Error). Comparing the results between the LSB algorithm and the proposed algorithm.
The results that we obtained indicate the efficiency and strength of the proposed algorithm, as it is characterized by its durability because of its resistance to many attacks carried out on the images that were hidden in the image to be hidden and hidden.
It was adopted on the Visual Studio 2016 environment because it contains highly efficient functions that deal with the proposed algorithm.
