Abstract:
1. Authenticating sealing tape, comprising a flexible thin elongated substrate, having an adhesive backing adapted to adhere the substrate to an object, a seal tamper indicator adapted to alert a user to an attempted release of the adhesive backing from the object, a set of optically machine readable elements having an irreproducible characteristic disposed along the surface of the substrate, wherein the set of optically machine readable elements and the optically readable pattern of digitally encoded information are each adapted to be read by a common optical machine reader, and a plurality of respectively unique machine readable identification portions comprising an optically readable pattern of digitally cryptographically encoded information, periodically disposed along a surface of the substrate, a respective one of the plurality of unique machine readable identification portions digitally encoding a unique identifier of the respective machine readable identification portion, and at least a portion of the irreproducible characteristic of set of optically machine readable elements within a region of the substrate proximate to the respective one of the plurality of machine readable identification portions, whereby the flexible thin elongated substrate and adhesive backing form a sealing tape adapted to seal the object, the seal tamper indicator reveals an unsealing of the sealing tape on the object, and the digitally cryptographically encoded information of the plurality of identification portions permit detection of a replacement of the sealing tape with a different sealing tape.
