A pest control and/or detection system generally includes an electrically conductive bait matrix including at least one carrier material that is at least one of palatable, a phagostimulant and/or consumable and/or displaceable by pests, and a plurality of electrically conductive particles. The electrically conductive particles are substantially randomly interspersed throughout the at least one carrier material. The at least one carrier material includes a thermoplastic material and/or a resin.

A method for creating an authentication tag includes receiving, at an authentication server, tagging device data and item data from a tagging device, authenticating, by the authentication server, the tagging device using the tagging device data, generating an authentication tag, and sending, by the authentication server, the authentication tag to the electronic device. The tagging device is affixed to an item, and the authentication tag comprises a digital signature provided by the authentication server.

Authenticating and managing item ownership and authenticity

A pest control and detection system generally includes an electrically conductive bait matrix including at least one carrier material that is at least one of palatable, a phagostimulant, consumable, and displaceable by pests, and a plurality of electrically conductive particles. The electrically conductive particles are substantially randomly interspersed throughout the at least one carrier material. The at least one carrier material includes at least one of a thermoplastic material and a resin.

A system for authenticating and managing the ownership of an item comprises a tagging device affixed to the item, wherein the tagging device comprises tagging device data, an item information system receiving the tagging device data and associated item data and storing the tagging device data and the item data, an owner registration and transfer system receiving owner registration data and ownership change requests and storing the ownership history, and an authentication system receiving authentication requests and generating a response based upon the information stored in the system or a connected system.

An efficient implementation of a cryptographic processor that dynamically updates the encryption state is described. The cryptographic processor can be implemented with a minimal number of gates, yet still perform cryptographic operations quickly. The cryptographic processor has an interface, a memory, a pseudorandom permutation block and control logic. The interface receives input data blocks and returns cryptographically processed data blocks. The memory is used to store an encryption state of the cryptographic processor. The pseudorandom permutation block transforms a portion of the encryption state that is modified for each input data block by at least the input data block and a previously transformed data block. The control logic routes data in the cryptographic processor to return cryptographically processed data blocks at the interface and update dynamically the encryption state stored in memory using the transformed data blocks from the pseudorandom permutation block.

Cryptographic processor with dynamic update of encryption state

An encryption and authentication technique that achieves enhanced integrity verification through assured error-propagation using a multistage sequence of pseudorandom permutations. The method generates intermediate data-dependent cryptographic variables at each stage, which are systematically combined into feedback loops. The encryption technique also generates an authentication tag with minimal post processing that is the size of the state.

Hybrid mode cryptographic method and system with message authentication

A single antenna single reader (SASR) system and method for locating a tag. The reader connects to a single antenna that is in motion. The reader transmits an interrogation signal to the tag. The reader receives a response signal from the tag. The reader determines the range of the tag from the reader, the received signal strength (RSS) of the response signal at the reader from the tag, and the maximum correlation of the response signal at the reader from the tag. The reader determines the location of the tag using range of the tag from the reader, received signal strength and maximum correlation of the response signal.

An object name system (ONS) for locating one or more servers associated with an Electronic Product Code (EPC) is described. The system utilizes translation format strings to translate an EPC to an EPC domain prefix. The ONS server matches the EPC number to the address of a second server which has extensive information about the product. The second server recognizes the incoming EPC's as belonging to a particular object or service.

A control system for routing data in an automatic identification system includes an event management system (EMS), a real-time in-memory data structure (RIED) and a task management system (TMS). The control system can be provided in a distributed hierarchical arrangement. The EMS of each control system can include filters which limit the amount of information provided to the next level in the hierarchy. In this manner the hierarchical control system network acts as a high volume data collector and processor. In some embodiments a level of the hierarchy can be removed spatially and/or temporally from an adjacent level in the hierarchy.
