Embodiments of the present disclosure generally relate to systems and methods for providing privacy to downstream owners of electronically tagged goods. In one implementation, the system may include at least one processor that may be configured to store IDs for a plurality of tags including at least a first owner ID and a second owner ID for a particular tag; associate first information of the particular tag with the first owner ID at a time when the first owner of the particular tag is recorded as owning the tag; record a transaction transferring ownership of the particular tag from the first owner to a second owner; and after the transfer of ownership, associate second information of the particular tag with the second owner ID, and prevent the first owner from accessing the second information.

With the purpose of having RFID tags that are cheap to produce and that are environmentally friendly, it is disclosed a method and a system to manufacture chipless RFID tags. The method and system comprises printing a conductive track on a carbon-based substrate and selectively heating the substrate on the parts comprising the conductive track. The printing of the conductive track envisages using an ink comprising at least one of a metal carbide, a metal boride or a metal nitride.

The present invention provides a series of structures that provide a unique electromagnetic signature that can be used as a standalone device or as part of a larger security system. This structure's design method of manufacturing ensures that is resilient to commonly used techniques for reverse engineering electronic components and counterfeiting and is able to be applied to devices or any product before or after fabrication is completed.

Embodiments of the present disclosure generally relate to systems and methods for providing access to information associated with electronically tagged goods. In one implementation, the system may include at least one processor configured to store tag IDs of a plurality of tags; and receive a pairing between a particular tag ID and a product ID. The at least one processor may also be configured to receive a pairing between the particular tag ID and an authorized entity associated with the particular tag ID; and receive, from a requester, a query including an encrypted tag ID of the particular tag. The at least one processor may also be configured to decrypt the encrypted tag ID; determine if the requester is the authorized entity; fulfill the query, if the requester is the at least one authorized entity; and deny the query if the requester is not the at least one authorized entity.

Embodiments of the present disclosure generally relate to a wireless identification fraud avoidance system and methods for use thereof. In one implementation, the system may include at least one transmitter configured to transmit a first signal to a plurality of identification tags and to cause the identification tags to transmit a second signal. The system may also include a first, proximate receiver configured to receive the second signal from the identification tags. The system may also include a second, more distant receiver configured to receive a third signal from a tag outside a transmission range of the at least one transmitter. The system may also include at least one processor configured to generate a potential fraud alert when the second receiver receives the third signal.

Embodiments of the present disclosure generally relate to a wireless identification tag configured to harvest ambient energy and transmit an identification signal intermittently, and system and methods for use thereof. In one implementation, the tag may include an antenna configured to receive ambient energy. The tag may also include an energy storage component configured to aggregate and store the received ambient energy. The tag may also include a transmitter electrically connected to the energy storage component and configured to transmit the identification signal. The tag may also include a circuit connected to the transmitter and configured to implement an identification transmission rule, to cause the transmitter to delay sending the identification signal even when sufficient energy for transmission of the identification signal is aggregated and stored in the energy storage component.

Embodiments of the present disclosure generally relate to a wireless identification tag configured to collect and store ambient energy for use in delayed transmission, and system and methods for use thereof. In one implementation, the tag may include a receiver for receiving ambient energy; a first capacitor for storing the ambient energy; and a second capacitor for collecting and storing the ambient energy. The second capacitor may have lower capacitance than the first capacitor. The tag may also include an inductor interconnecting the first capacitor and the second capacitor. The tag may also include circuitry configured such that ambient energy received by the receiver is initially stored in the second capacitor and subsequently transferred to and stored in the first capacitor. The tag may also include a transmitter electrically connected to first capacitor, to enable the energy stored in the first capacitor to power the transmitter.
