Abstract
Finally, we present a new approach to the watermarking problem that is based on traditional cryptographic arguments. Here, the attacker is assumed to have enough information about the algorithmic steps of information hiding schemes (except for the secret key). Within this scenario he has access to the decoder; his goal is to break the scheme with a finite number of trials by reliably finding or estimating the secret. We propose an image watermarking approach that is designed as a first step for such a situation. We also present a video watermarking technique that combines the proposed image hashing and watermarking techniques.
