I need code for Encrypted reversible data hiding on compressed images

I am doing my project on encrypted reversible data hiding on compressed images and I have done till compression and used huffman code for compression.What could be efficint techniques for encryption and data hiding

Answer 1

[Image Analyst]

See this in my File Exchange to encode text into an image: http://www.mathworks.com/matlabcentral/fileexchange/54155-encoding-text-into-image-gray-levels

Also, see the attached watermarking demo using the LSB method to encode an image into a bitplane.

It's not really encrypting, it's more of encoding. We're not allowed to discuss or post encryption info and files on Mathworks servers.
