Abstract

Digital watermarking is a copyright protection technique that has been developed in response to the rapid growth of networking and internet technology. Possessing also validation capabilities, it is superior to most forms of traditional network safety methods based on encryption and so has attracted widespread attention in recent years. At present, two common forms of watermarking techniques are in use: robust watermarking and fragile watermarking. While the former technique is highly robust, it sorely lacks the capability to recognize forged signals. The latter technique, on the contrary, though being highly sensitive to signal authenticity is overly vulnerable to normal signal processing. This paper introduces a digital watermarking technique (algorithm) that is based on wavelet packages. By embedding the watermarks in the middle-frequency segment of the wavelet package, this new technique possesses all the desirable properties of the previous algorithms, as indicate by experimental results.
