摘要:
Aspects of the present invention describe a method of tracking an item, comprising. The items is associated with a tag and capable of responding to a query from a tag reader and tag combination. The tag reader and tag combination capable of identifying the item associated with the tag using a tag reader. In operation, a tag reader makes a request to at least one tag reader and tag combination for the identity of an item associated with a tag. The tag reader and tag combination identifies the item associated with the tag and provides the identity of the item and tag to the tag reader.

A seal for a package includes a circuit having electrical characteristics that change under mechanical deformation and an attaching material coupled to the circuit and for attaching the circuit to the package. The seal is attached to the package and processed prior to shipping to establish an untampered state for the seal. This includes identifying a circuit on the sealed package according to a seal type associated with the seal, recording one or more characteristics associated with the circuit from the seal and storing the seal type and one or more characteristics associated with the circuit from the seal for later comparison. To detect tampering to the package, the seal type and corresponding seal and circuit for the seal is identified, the characteristics associated with a circuit from the seal are determined and compared with the previous characteristics recorded when the seal was initially applied to the package. If the comparison indicates that a mechanical deformation of the seal occurred, it is possible the seal and package were tampered with during shipment or delivery.

A mobile telephone (10), an advertiser, broadcasts an advertisement over a wireless short range piconet link to another mobile telephone (12), a consumer. The advertisement is broadcast with a predetermined set of classification tags and the consumer phone (12) has a filter set to accept only certain adverts. When an advertisement of interest is received by the consumer phone (12) it requests further details automatically via the piconet link and the advertiser phone (10) provides then automatically via the piconet link. When the consumer wishes to reply to the advertisement they contact the advertiser phone (10), or an advertiser device, via a long range cellular link (16).

A power control circuit is used to control the power supplied to a circuit from a power source. The power control circuit is operable to connect and disconnect the power source from the circuit. The power control circuit connects the power source to the circuit in response to an externally applied magnetic field.

In one embodiment of the present invention, a source point of a supply chain secures shipment of an object by devising an encryption key and encrypting a message using the encryption key to produce an encrypted message. A portion or portions of the encryption key and the encrypted message are included or incorporated within the object to be shipped, packaging surrounding the object, and/or labels affixed to the object or packaging, prior to shipping the object to a destination point within the supply chain. Upon receipt of the object from the supply chain, the destination point can extract the portion or portions of the encryption key and the encrypted message from the object, packaging surrounding the object, and/or labels affixed to the object or packaging, obtain the remaining portion of the encryption key directly from the source point, reassemble the encryption key, and decrypt the encrypted message to produce a computed message. The destination point can then obtain the original message from the source point and compare the original message to the decrypted message in order to determine whether or not the shipment is authentic.

Methods and systems of the present invention employ perturbation techniques for configuring RFID-tag-reader networks in order to achieve increased overall efficiency of a network of RFID-tag readers. According to described embodiments of the present invention, individual RFID-tag readers within a multi-RFID-tag-reader network may be removed or shut down, or RFID-tag readers may be displaced relative to one another, in order to remove interferences between RFID-tag readers and to increase the interrogation efficiency of the multi-RFID-tag-reader network. A method embodiment of the present invention schedules a multi-RFID-tag-reader network as a cycle of power-on/power-off intervals.
摘要:
A package identifier for a package having at least one sub-package is generated. A package identifier generating function is performed on at least one sub-package identifier of the at least one sub-package to generate the package identifier. In addition, the generated package identifier is stored for use in authentication.
