The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of controlling access to a resource (140), comprising embedding an authorization code in a signal (120) by means of a watermark and transmitting the watermarked signal (120) to a verifying device (130), and in the verifying device (130), extracting the authorization code from the watermarked signal (120) and authorizing an operation to be performed on the resource (140) in dependence on the extracted authorization code.
2. The method of claim 1, in which the resource (140) comprises a computer program and the authorization code causes the verifying device (130) to grant permission for executing the program.
3. The method of claim 1, in which the resource (140) comprises a computer program and the authorization code causes the verifying device (130) to grant permission for activating a module of the computer program.
4. The method of claim 1, in which the resource (140) comprises an electronic game and the authorization code causes the verifying device (130) to grant permission for activating a cheat function in the electronic game.
5. The method of claim 1, in which the resource (140) comprises a multimedia object and the authorization code causes the verifying device (130) to grant permission for at least one of: a rendering of the multimedia object and the making of a copy of the multimedia object.
6. The method of claim 2, in which the permission is limited in time.
7. The method of claim 1, in which the resource (140) comprises a computer program and the authorization code causes the verifying device (130) to revoke a previously granted permission for executing the program.
8. The method of claim 7, in which the authorization code further causes the verifying device (130) to authorize a further operation to be performed on the resource.
