Abstract
A method for authenticating a document comprises obtaining the contents of a document, obtaining biometric characteristics from an individual, forming a message based on the contents of the document and the biometric characteristics of the individual, generating a digital signature based on the message and a key, and writing the digital signature to an Radio Frequency Identification (RFID) tag affixed to the document.
Claims25
A method for authenticating a document, comprising:
- obtaining optical character recognition (OCR) characteristics of contents of the document, wherein the contents of the document comprise at least a portion of text from the document, wherein the at least a portion of text from the document is printed in an ink that is only visible when viewed with a lighting feature;
- obtaining, separate from the document, biometric characteristics from an individual authorized to access the document;
- forming a message based on the OCR characteristics of the at least a portion of the text from the document and the separately obtained biometric characteristics of the individual authorized to access the document by illuminating the document with the lighting feature;
- generating a digital signature based on the message and a key;
- writing the digital signature to a radio frequency identification (RFID) tag affixed to the document;
- in response to an attempt to copy the document, reading the digital signature from the RFID tag;
- verifying an individual attempting to copy the document based on one or more biometric characteristics collected from the individual attempting to access the document and at least a portion of the biometric characteristics of the individual authorized to access the document included in the message comprising the digital signature;
- and
- in response to successfully verifying the individual attempting to copy the document, granting the individual copy access to the document, wherein the individual is granted copy access to the document by activating the lighting feature in a copier that allows the copier to copy the at least a portion of the contents of the document printed in the ink that is only visible when viewed with the lighting feature.

A method for authenticating a document and for controlling access to the document, the method comprising:
- obtaining optical character recognition (OCR) characteristics of contents of the document, wherein the contents of the document comprise at least a portion of text from the document, wherein the at least a portion of text from the document is printed in an ink that is only visible when viewed with a lighting feature;
- obtaining, separate from the document, biometric characteristics from an individual authorized one or more levels of access to the document;
- forming a message based on the OCR characteristics of the at least a portion of text from the document and the separately obtained biometric characteristics of the individual authorized one or more levels of access to the document by illuminating the document with the lighting feature;
- generating a digital signature based on the message and a key;
- writing the digital signature to a radio frequency identification (RFID) tag affixed to the document;
- in response to an attempt to read the document, reading the digital signature from the RFID tag;
- verifying an individual attempting to read the document based on one or more biometric characteristics collected from the individual and at least a portion of the biometric characteristics of the individual having authorized access to the document included in the message comprising the digital signature;
- and
- in response to successfully verifying the individual attempting to read the document, granting the individual read access to the document, wherein the individual is granted read access to the document by activating the lighting feature to illuminate the at least a portion of the contents of the document printed in the ink that is only visible when viewed with the lighting feature.
