SECURITY POLYMER THREAT DETECTION DISTRIBUTION SYSTEM
First Claim
1. A method of determining exposure of a media to an item of interest, the method comprising:
- providing the media at a first location, wherein the media has a unique identifier;
determining the unique identifier of the media at a second location;
creating a first image of the media;
applying, to the media, detection material sensitive to the item of interest, wherein;
the item of interest is one of a chemical, a biologic compound, or an explosive; and
the applying occurs at the second location;
creating, at the second location, a second image of the media;
analyzing the first image and the second image to determine if the detection material has sensed the item of interest, wherein the analyzing includes determining an optical change between the first image and the second image; and
indicating a result based, at least in part, on the analyzing.

Abstract
Embodiments disclosed enable the detection of the presence of chemical, biological, and/or explosive (CBE) substance or other items of interest on individuals handling tickets, fobs, passes, smartcards, or other media. Embodiments generally contemplate issuing media at a first location and analyzing the media at a second location. Material sensitive to CBE substance can be applied to the media at the first and/or second location. An adhesive also may be used to attract and/or retain particles to the media for analysis and/or adhere the detection material to the media. Such embodiments can be utilized in airports, transit stations, and other applications where security against threats posed by CBE substance may be a concern.

13. A device for determining exposure of a media to an item of interest, the device comprising:
-
a media imager configured to create at least one image of the media; a detection material applicator configured to apply, to the media, detection material sensitive to the item of interest, wherein the item of interest is one of a chemical, a biologic compound, or an explosive; a processing unit configured to analyze the at least one image of the media to determine if the detection material has sensed the item of interest based, at least in part, on an optical characteristic of the detection material in the at least one image; and an analysis indicator configured to indicate a result based, at least in part, on an analysis of the at least one image of the media. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A non-transitory machine-readable storage medium comprising instructions embodied thereon that, when executed by at least one machine, cause the at least one machine to:
-
determine a unique identifier of the media; create a first image of the media; apply, to the media, detection material sensitive to the item of interest, wherein the item of interest is one of a chemical, a biologic compound, or an explosive; create a second image of the media; analyze the first image and the second image to determine if the detection material has sensed the item of interest, wherein the analyzing includes determining an optical change between the first image and the second image; and indicate a result based, at least in part, on the analyzing. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
