Verification of an item

摘要

Mechanisms for verification of an item. A controller reads out signals from an antenna array comprising a plurality of individual antenna elements that is configured to overlay an item that generates radio frequency (RF) emissions. The signals quantify the RF emissions received by antenna elements from the item. The controller generates an ad hoc RF emission signature based on the signals. A predetermined RF emission signature associated with the item is accessed. The ad hoc RF emission signature and the predetermined RF emission signature are compared to determine a verification status, and the controller performs a verification action based on the verification status.

主权项

1. A method for verification of an item, comprising:
reading out, by a controller comprising a processor from an antenna array comprising a plurality of individual antenna elements that is configured to overlay an item that generates radio frequency (RF) emissions, signals that quantify the RF emissions received by antenna elements from the item; generating an ad hoc RF emission signature based on the signals; accessing a predetermined RF emission signature associated with the item; comparing the ad hoc RF emission signature and the predetermined RF emission signature to determine a verification status; and performing a verification action based on the verification status.
