Digital watermarking is becoming more and more important with the emergence of the World Wide Web.

Given then inherent nature of the data to be watermarked, it is difficult to come up with a good algorithm satisfying all the 'goodness criteria'.

Of all the algorithms, suggested, the NEC algorithms is the most robust, but it has a heavy overhead associated with it.

Stirmark is able to remove watermarks embedded using current algorithms.

Future work will be to find out the class of information hiding functions that obey the constraints imposed and use them to develop more robust algorithms for the future.
