SUMMARY:
In this article, we strive to present a general introduction of steganography, or concealment, as sometimes just is not known. Then we turn to data hiding in images. In considering these data hiding techniques, we have in mind, Bender's technical characteristics, such as data loss, the cover should be minimized and hidden data should be made as immune as possible attack data manipulation cover. Steganography in images really come of age with the invention of fast, powerful computers. The software is easily available from the Internet a ....etc

matlab code for copy move forgery detection using dct

%L = imread('images/lena3.jpg');
L = imread('images/Toronto2_F.png');
L=rgb2gray(L);
figure(1);
imshow(L);

b=256; % block size used to look for duplicates
b1=sqrt(b);
Nn = 5; % how many close rows to check
Nd = 15; %Threashold
Nc=26; % Truncate PCA at this length
Nt=26;

% calculate the total size of the image
n = numel(L);

b2 = sqrt(n)-sqrt(b)+1;
% calculate Nb
Nb= power((sqrt(n)-sqrt(b)+1),2);

% the matix of Nc plus the position
M=zeros(Nb, Nc);
% temp index array
Mi = zeros(Nb, 2); ....etc
