Abstract

In the field of content distribution a typical problem is the protection of Digital Rights information (DRM), which is appended to the content and written on a record carrier in the form of a corresponding written pattern, from tampering by malicious users. According to some known schemes, the protection is implemented by linking the DRM to some physical distinctive feature of the corresponding written pattern. From this distinctive feature fingerprint data can be extracted with some conventional method, and used for the authentication of the DRM. The invention proposes a method of writing data wherein the formed written pattern has a radial offset, which is formed during writing as result of a non- controllable substantially random process. A corresponding apparatus for writing data, a method and an apparatus for extracting fingerprint data and a record carrier are also described.
