Conclusion

The project dealt with the techniques for steganography and watermarking as related to image science

A number of techniques spanning a wide area was investigated and implemented wherever possible. It is clear that this is a fascinating inter-disciplinary field which is extremely relevant especially in the current internetworked age where information transfer is at an all-time high and copyright enforcement, piracy, digital rights management are the buzzwords of the day.

It is also my belief that this project reiterated the fundamentals that were thought in the course about the limits of our human visual system and also how important part the statistical properties of an image are. Also the amount of data for images and video are so large that these are ideal mediums for data hiding. All these points were explored in this project

Specifically speaking, the spread-spectrum method of watermarking provide quite an effective against transformations. The simple LSB technique was also surprising effective.

The amount of literature on this subject is huge and staggering, especially being cross-disciplinary to mathematicians, cryptographers, vision scientists, network engineers.

Thanks, very much, for the course and for the project.
