INTEGRATED UNIT FOR READING IDENTIFICATION INFORMATION BASE ON INHERENT DISORDER

摘要

The invention provides an authentication unit for reading identification and/or authentication information from a tag or object. The authentication unit includes a near-field reader configured to read a first identification feature based on inherent disorder, and a far-field reader configured to read a second identification feature, such as a bar code, optical characters, or an RFID tag. The near-field and far-field readers may be combined in a single integrated scanning module, which also includes circuitry for receiving signals from the readers, and an interface for communicating with a host device.

主权项

1. An authentication unit for identifying a tag or an other object adapted to be identified, wherein the authentication unit is adapted to read a first signal from a first set of identification features and a second signal from a second set of identification features, wherein the sets of identification features are housed on, in, or near the tag or object to be identified, and wherein the first set of identification features comprises a disordered material, and the first signal read from the first set of identification features is dependent on the intrinsic disorder of the material.
