Secret Image Hiding technique(Steganography) using matlab

Hi All.I am Pravat Satpathy from Bhubaneswar. Here is the matlab Code for Process of Image Hiding using LSB Technique (Steganography) .It's a nice Project for begineers and matlab lovers.Pl also go through my channel https://www.youtube.com/channel/UCT7mmGA4BmM6MILdYv14THQ for hardware Projects covername = input('Enter image file name with extension: ', 's'); messagename = input('Enter message image file name with extension: ', 's'); cover = imread(covername); %cover = imread('Cover_image.bmp') message = imread(messagename); %message = imread('secret_image.bmp') figure(1), imshow(cover); title('Original Image (Cover Image)'); figure(2), imshow(message);title('Image to Hide (Message Image)'); cover=double(cover); message=double(message); imbed= input('no. of bits to be made as secret bits='); %imbed= 2 %or 4 or 8 %shift the message image over (8-imbed) bits to right messageshift=bitshift(message,-(8-imbed)); %show the message image with only embed bits on screen %must shift from LSBs to MSBs showmess=uint8(messageshift); showmess=bitshift(showmess,8-imbed); figure(3),imshow(showmess);title('embed Image to Hide '); %now zero out imbed bits in cover image coverzero = cover; for i=1:imbed coverzero=bitset(coverzero,i,0); end %now add message image and cover image coverzero1=imresize(coverzero,[250,250]); coverzero1=double(coverzero1); stego = uint8(cover-messageshift); figure(4),imshow(stego);title('Stego image'); %save files if need to %4 bit file that was embedded = same as file extracted imwrite(showmess,'showmess4.bmp'); %use bmp to preserve lower bits %jpg will get rid of them %stego file imwrite(stego,'stego_op.bmp');
