Abstract: A method includes receiving distributed sensing information on one or more characteristics associated with a subject from distributed sensors distributed between a starting location spaced from a resolution location and the resolution location. If the subject is sensed by the plurality of distributed sensors, in combination without any break in chain of custody (“COC”), the method does not adjust a reliability of the distributed sensing information caused by any break in COC. If there are one or more time gaps in the COC, the method determines one or more COC factors based on the time gaps and adjusts the reliability of the distributed sensing information based on the one or more COC factors. The method determines a trust score of the subject to assess security concern of the subject based on the distributed sensing information and the reliability thereof, and resolves the security concern based on the trust score.

Abstract: A method includes receiving distributed sensing information on one or more characteristics associated with a subject from sensors distributed between a starting location spaced from a resolution location and the resolution location, the resolution location including a targeted screening area, the characteristics being obtained from the sensors observing a plurality of candidate subjects including the subject; determining, based on the information on the characteristics, which category of a plurality of categories is to be associated with the subject for a targeted screening process to be performed in which respective categories correspond to different thresholds applied in the targeted screening process; and electronically communicating information for the category associated with the subject to an electronic device, to direct the subject to a location of the targeted screening area which corresponds to the category, for performing the targeted screening process of the subject corresponding to a threshold ass

Abstract: An example method to characterize an anomaly includes obtaining information about an item using a first mode scan and detecting whether the item contains an anomaly based on the information. The method further includes determining, responsive to detecting the anomaly, an area of interest of the item corresponding to a location of the anomaly, and determining a strategy including a procedure to obtain other information of the area of interest. The method refines a characterization of the anomaly based on the other information, and compares the characterization of the anomaly to a predetermined criterion. The method iteratively revises the strategy to perform additional available procedures, to further refine the characterization of the anomaly. When the characterization of the anomaly meets the predetermined criterion corresponding to a prohibited item, the method identifies the anomaly as prohibited.
