Ideas to make code for Robust Image Watermarking


I need to make following Project on Image Watermarking, need suggestions of maximum people how to start this.
1.) My project shall include a Host file of size(M*M), which will hide a watermark of size(N*N) (may be a grayscale, text or true color image).
2.) Need to encrypt watermark( Suggestions are needed whether use selective encryption, ciphering), where to get maximum help and how to implement this.
3.) Which algorithm I should prefer to encrypt watermark and why?????
4.) Ideas to make Key for Encryption.
5.) Idea to embedd the watermark in host image( Either to use DWT,SVD,DCT,Fibonacci Haar Wavelet) and in which band???????????
6.) What will I loose or gain on embedding in lower frequency bands and higher frequency subbands.
7) How I can make watermark Robust to Rotation, Scaling, Croping, Resizing. Ideas to generate such code.
8.) What performance parameters will decide my robustness.
9.) How to Extract watermark and will they be extracted after attacking the watermarked image.
I will be grateful, if you give your valuable suggestions.

Read LQ Rules, specifically the twelfth bullet.

Read how to ask an effective question.

And further understand that the way this forum works is not like ordering fast food where you give all your requirements and then people offer up answers, you need to work on your tasks and assignments on your own and if/when you get stuck you illustrate what you've tried, what you've thought of, and ask if anyone has suggestions at that point.

Note this is a cross post, the other question at least has more detail, but still poorly worded http://www.linuxquestions.org/questi...44#post5358144
