Abstract
Devices and methods are provided for managing the identity of media content data. A server node processes metadata associated with a plurality of media content data files to generate a corresponding master identifier for each of the media content data files. A client node then provides the server node a first set of metadata corresponding to a media content data file that has no associated master identifier. In turn, the server node processes the first set of metadata to identify a corresponding master identifier and a second set of associated metadata, which it provides to the client node. The client node processes the second set of metadata to identify a matching set of metadata stored in its database of identification data and metadata. If found, the client node associates the master identifier with a second media content data file corresponding to the matching set of metadata.
