Abstract

The present invention relates to a method and a unit for securely providing watermarking data for watermarking a content. Watermarking data consists of cipher texts that are generated based on the content, a watermark and a number of encryption parameters. The invention also provides a method and a unit for securely watermarking a content at an untrusted location, such as at the location of a content consumer. The watermarking unit receives a number of cipher texts provided for instance by a watermarking data unit in accordance with the invention, and calculates the watermarked signal based on the cipher texts.
