Abstract
Unauthorized copying and distribution of digital data is a severe problem in protecting intellectual property rights. The embedding of digital watermarks into multimedia content has been proposed to tackle this problem, and many different schemes have been presented in the last years. However, almost all of them are symmetric, meaning the key used for watermark embedding must be available at the watermark detector. This leads to a security problem if the detectors are implemented in consumer devices that are spread all over the world. Therefore, the development of asymmetric schemes becomes important. In such a scheme the detector only needs to know a public key, which does not give enough information to make watermark removal possible. In this paper, we review recent proposals for asymmetric watermarking and analyze their performance.
