Patent ID: 8098137

Claim:
A media passport system, comprising: a plurality of radio frequency identification (RFID) transponders attached to a plurality of removable mediums; a plurality of RFID readers installed in rooms, wherein each RFID reader has a unique identification (ID); and a security server connected to the plurality of RFID readers via a network, wherein the security server hosts a zone-table comprising: a unique ID information of the plurality of radio frequency identification (RFID) transponders; a zone information determined as a subset of the unique IDs of the plurality of RFID readers; and a unique ID information of the plurality of RFID readers, wherein the unique ID information of the plurality of RFID transponders is mapped to the zone information and the unique ID information of the plurality of RFID readers such that the unique ID information of a particular one of said plurality of RFID transponders is included in a same row of the zone-table as a security zone to which the removable medium corresponding to the particular one of said plurality of RFID transponders is allowed access and the unique ID information of a particular one of the plurality of RFID readers located in the security zone to which the removable medium corresponding to the particular one of said plurality of RFID transponders is allowed access, wherein each RFID transponder transmits its unique ID to an RFID reader in the plurality of RFID readers when the RFID transponder passes by the RFID reader, wherein the RFID reader transmits the unique ID of the RFID transponder and the unique ID of the RFID reader to the security server, wherein the security server determines the RFID reader that receives the unique ID of the RFID transponder, wherein the security server determines a zone where the RFID reader is located, wherein the security server checks the zone-table to determine whether the unique ID of the RFID transponder is allowed in the zone where the RFID reader is located, wherein the unique ID of the RFID transponder is allowed in the zone where the RFID reader is located, only if the unique ID information of the RFID transponder, and the zone information where the RFID reader that received the unique ID of the RFID transponder is located are on a same row of the zone-table wherein the unique ID of the RFID transponder is not allowed in the zone, if the unique ID information of the RFID transponder and the zone information wherein the RFID reader that received the unique ID of the RFID transponder is not located on the same row of the zone table, and wherein the security server sounds an alarm if the unique ID of the RFID transponder is not allowed in the zone where the RFID reader is located.
