Surveillance with reanalysis of screening data

Abstract

A surveillance system may include at least one controller configured to receive information data from at least one information source and to control operation of at least one controllable subsequent information source based, at least in part, on the information data. A surveillance method may include analyzing screening data, obtaining information data, and reanalyzing the screening data based, at least in part, on the obtained information data.

1 . A surveillance method, comprising:
 screening by a surveillance system apparatus at least a portion of a subject-associated item associated with and not including a person being screened, and not including an item in the physical possession of the person during screening of the person;   generating by the surveillance system apparatus screening data based, at least in part, on the screening of at least a portion of the subject-associated item;   analyzing the screening data by a processor of the surveillance system apparatus;   obtaining by the surveillance system apparatus, after analyzing the screening data, information data derived from at least one of (a) the person and (b) one or more subject-associated items other than the screened subject-associated item; and   reanalyzing by the processor of the surveillance system apparatus the screening data based, at least in part, on the information data, and in a manner that is at least partially different from the analyzing of the screening data.   
     
     
         2 . The method of  claim 1 , in which screening at least a portion of a subject-associated item includes detecting object information about an object potentially in the screened subject-associated item, and generating screening data includes generating screening data that includes, at least in part, the object information. 
     
     
         3 . The method of  claim 2 , further comprising assigning one or more of a relative weight, value, attribute, and relative indicator to the object potentially in the screened subject-associated item based, at least in part, on the screening data. 
     
     
         4 . The method of  claim 3 , further comprising, after reanalyzing, reassigning one or more of a relative weight, value, attribute, and relative indicator to the object potentially in the screened subject-associated item based, at least in part, on the information data.

         7 . The method of  claim 1 , in which screening at least a portion of a subject-associated item includes detecting, in the subject-associated item, one or more of a metal substance, an explosive substance, a chemical substance, and a feature identifying the person associated with the subject-associated item.

         9 . The method of  claim 8 , in which screening at least a portion of the person includes imaging at least a portion of the person. 
     
     
         10 . The method of  claim 9 , in which imaging at least a portion of the person includes transmitting toward and receiving from the person in a subject position, electromagnetic radiation in a frequency range of about 100 MHz to about 2 THz, from positions spaced from the subject position. 
     
     
         11 . The method of  claim 8 , in which screening at least a portion of the person includes detecting, on the person, one or more of a metal substance, an explosive substance, a chemical substance, and a feature identifying the person. 
     
     
         12 . The method of  claim 1 , in which obtaining information data includes screening at least a portion of the one or more subject-associated items other than the screened subject-associated item, and generating subject-associated item screening data, at least as part of the information data, based on the screening at least a portion of the one or more subject-associated items other than the screened subject-associated item. 
     
     
         13 . The method of  claim 12 , in which screening at least a portion of the one or more subject-associated items other than the screened subject-associated item includes imaging at least a portion of the one or more subject-associated items other than the screened subject-associated item. 
     
     
         14 . The method of  claim 13 , in which imaging at least a portion of the one or more subject-associated items other than the screened subject-associated item includes transmitting, toward the one or more subject-associated items other than the screened subject-associated item, electromagnetic radiation in a frequency range of about 30 PHz to about 30,000 PHz.
