In metadata, an identification scheme is used to identify unique records in a set. If a data element is used to identify a record within a data set, the data element uses the Identifier representation term.
Content Metadata Directory Services
ActiveUS20070156726A1Improve interoperabilityIncrease the number ofMultimedia data indexingDigital data processing detailsContent IdentifierSystems management
The content metadata directory system connects consumers of identified content to managed metadata databases and other digital resources. The system manages links between identifiers in content objects and metadata sources. It supports a variety of different type of content identifiers and allows for overlap among different content identification schemes. One method of associating a content object with metadata uses a combination of a content identifier and a bounding identifier to enable handling of disparate sets of content identifiers for content objects with potentially conflicting content identifiers. The method receives a content identifier for a content object from among a set of content identifiers and provides a unique bounding identifier for the set of content identifiers. This unique bounding identifier is used in combination with the content identifier to form a globally unique identifier for the content object. This globally unique identifier is associated with a metadata source, which enables routing of a user to the metadata source.

InactiveUS6237097B1Reduce in quantityConfidenceKey distribution for secure communicationPublic key for secure communicationParallel computingEngineering
The invention provides for robust efficient distributed generation of RSA keys. An efficient protocol is one which is independent of the primality test "circuit size", while a robust protocol allows correct completion even in the presence of a minority of arbitrarily misbehaving malicious parties. The disclosed protocol is secure against any minority of malicious parties (which is optimal). The disclosed method is useful in establishing sensitive distributed cryptographic function sharing services (certification authorities, signature schemes with distributed trust, and key escrow authorities), as well as other applications besides RSA (namely: composite ElGamal, identification schemes, simultaneous bit exchange, etc.). The disclosed method can be combined with proactive function sharing techniques to establish the first efficient, optimal-resilience, robust and proactively-secure RSA-based distributed trust services where the key is never entrusted to a single entity (i.e., distributed trust totally "from scratch"). The disclosed method involves new efficient "robustness assurance techniques" which guarantee "correct computations" by mutually distrusting parties with malicious minority.

A method for simultaneously reading a serial number and / or other information from multiple colliding RF signals from RF identification tags (1-5) requires minimal additional logic in the tag's processor and provides for a powerful and rapid sorting and identification scheme. This technique employs a primary communication channel and multiple secondary channels, A locator or reader unit (6) interrogates the tags (1-5), which respond with an RF signal. Upon receiving multiple signals, the locator or reader unit (6) commands the RFID tags (1-5) and requires them to transmit another response, which is transmitted in one of the secondary channels based on a portion of their unique serial identification number, thereby forcing the tags (1-5) to sort in the secondary channels. These secondary channels are assigned using a portion of the unique serial identification numbers for the tags. The reader (6) then detects an acknowledgment in the occupied secondary channels and commands a tag (1-5) in a particular channel to move to the primary channel. Once the signal is transmitted in the primary channel, the reader (6) reads the identification number. If there is further collision, the collided tags are returned to the secondary channel and sorted again using a different portion of their ID number. This process continues until all the tags (1-5) are sorted and identified. Once the tags (1-5) are all sorted, the tags (1-5) are assigned yet another channel distinct from the secondary channels that are used for sorting.
