Data Hiding in Images

Generally you can not get any such readily usable code for such complex implementation from anywhere in the  world.   But you can develop such code from scratch.

Further, as far as I know, there is no Lossless Hiding in Images. Even in all kind of Steganographic techniques and Watermarking techniques, the host image will get distorted to some minimum level(at least).

Stepts to Achieve your Goal :

1. First of all try to simplify your goal as follows – I mean remove the complex things from it.

• Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
• Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
• Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography
• Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography

2. Finally you end up with a simple thing :

           Data Hiding in Images

3. You may find many freely available Data Hiding algorithm/code.

4. Start your project with a simple and suitable  code for “Data Hiding in Images.”

5 After successfully implementing a simple data hiding model, you may try to extend it.

6. Now you may improve it by adding “retrieval part” and do a  “Reversible Data Hiding in Images”

7. And then you may improve it as “Reversible Data Hiding in Images with Public Key Cryptography”

8. But I doubts that there is no way to do a “Lossless and Reversible Data Hiding in Encrypted Images with Public Key Cryptography”

Simple way to develop such Image processing based application is prototyping it with Matlab software.

Search Internet with keyword “steganography code in matlab” or “steganography code in C++” – you will find lot of such code – you may start your project by selecting one such simple and suitable code.
