Abstract: A surveillance detection apparatus for detecting an intruder to a restricted space includes a short range radio transceiver and a processor. The short range radio transceiver, which has a predefined limited range, causes the surveillance detection apparatus to send an intrusion signal to the processor in response to the short range radio transceiver receiving a short range radio signal from a communication device that is in the possession of an intruder, who is not pre-authorized by the processor to be within the predefined limited range of the short range radio transceiver, and thus the restricted space. In response to determining that the communication device is not pre-authorized to be within the predefined limited range of the short range radio transceiver, the processor generates an intruder alert.

Abstract: A method, computer program product, and computer system for identifying a first set of query results generated from a first query executed at a first time. A second set of query results generated from the first query executed at a second time is identified. One or more changes between the first set of query results and the second set of query results is determined. A second query is generated based upon, at least in part, the one or more changes.
