The present invention relates to a method, a device and a system for preventing unauthorized introduction of content items in a network containing compliant devices and enabling users in the network to be anonymous. A basic idea of the present invention is to provide a CA ( 206 ) with a fingerprint of a content item to be introduced in a network at which the CA is arranged. Further, the CA is provided with an identifier of a content introducer ( 201 ), which introduces the particular content item in the network. The CA compares the fingerprint to a predetermined set of fingerprints, and content item intro<img id="CUSTOM-CHARACTER-00001" he="3.13mm" wi="3.13mm" file="US20080152146A1-20080626-P00001.TIF" img-content="character" img-format="tif"/> duction is allowed if the content itemfingerprint cannot be found among the fingerprints comprised in the set. On introduction of the content item, the CA generates a pseudonym for the content introducer and creates a signed content ID certificate comprising at least said fingerprint and a unique content identifier for the content item and the pseudonym of the content introducer.
