Steganographie - Verschlüsseln und Entschlüsseln einer Nachricht in einem Bild mit MATLAB

Hiding/Encrypting a secret message behind an image using simple image processing technique,
The core idea is to extract 8 binary bit planes from a greyscale image and change one of them to our message binary image and then merge all that 8 planes to get a greyscale image back.

Try out yourself with some different Base images and on different bit positions, you can share your queries in the comment section.

Commands used:

1. bitget : extracts the desired bit from all the values of a given matrix

2. bitset : sets the bit in the given matrix at a given position.

Note: It is essential to store an encrypted image in ".bmp" format as it is the only format which doesn't compress image because if you save the image in any other format, it gets compressed and the message may be lost!!!

We also solve problems on-demand, Stuck in Matlab/python during your project? Need help? mail the problem at pnplaboratory@gmail.com, we will try to give a solution as soon as possible.
