Claim 1
Independent Claim
53 words
A document validating system that includes a physical characteristic reader for automatically reading a physical characteristic of a person presenting said document and multiple hidden digital watermarks from different elements of said document, and a comparator for comparing the output of said physical characteristic reader with information stored in said hidden digital watermarks.
Claim 2
Dependent Claim
53 words
A document validating system that includes a physical characteristic reader for automatically reading a physical characteristic of a person presenting said document and multiple hidden digital watermarks from different elements of said document, and a comparator for comparing the output of said physical characteristic reader with information stored in said hidden digital watermarks.
Claim 3
Independent Claim
94 words
A system for validating a security document, said document containing hidden digital watermarks that carry watermark payload data, said system comprising: a first computer system coupled to a second computer system, the second computer system being remote from the first, the first computer system including an optical scanner producing scan data corresponding to said document, the first computer system further including a digital watermark decoder receiving said scan data and outputting said watermark payload data, said watermark payload data being encrypted, the first and second computer systems cooperating to decrypt the watermark payload data.
Claim 4
Independent Claim
94 words
A system for validating a security document, said document containing hidden digital watermarks that carry watermark payload data, said system comprising: a first computer system coupled to a second computer system, the second computer system being remote from the first, the first computer system including an optical scanner producing scan data corresponding to said document, the first computer system further including a digital watermark decoder receiving said scan data and outputting said watermark payload data, said watermark payload data being encrypted, the first and second computer systems cooperating to decrypt the watermark payload data.
Claim 5
Dependent Claim
36 words
The system of claim 2 in which said second computer has a memory storing decryption data, said data being transferred to the first computer for use at the first computer to decrypt the watermark payload data.
Claim 6
Dependent Claim
39 words
The system of claim 2 in which the second computer includes a decryption system having an input for receiving watermark payload data from the first computer, and an output for providing decrypted watermark payload data to the first computer.
Claim 7
Dependent Claim
26 words
The system of claim 2 in which the decryption proceeds in accordance with unencrypted payload data discerned by the first computer system from the scan data.
Claim 8
Dependent Claim
25 words
The system of claim 5 in which the unencrypted payload data comprises a document identifier printed on the document in OCR or bar code form.
Claim 9
Independent Claim
55 words
A method of verifying the identity of a person who presents and identification document comprising the steps of automatically reading a physical characteristic of said person presenting said identification document, reading a hidden digital watermark from said identification document, and comparing the output of the physical reader with information stored in the hidden digital watermark.
Claim 10
Independent Claim
55 words
A method of verifying the identity of a person who presents and identification document comprising the steps of automatically reading a physical characteristic of said person presenting said identification document, reading a hidden digital watermark from said identification document, and comparing the output of the physical reader with information stored in the hidden digital watermark.
Claim 11
Independent Claim
107 words
A system for validating a security document presented by a person, said security document containing a hidden digital watermark that contains watermark payload data, said system comprising: a first computer system coupled to a second computer system, the second computer system being remote from the first, said first computer system including (a) an optical scanner producing a digital image of said security document, (b) a digital watermark decoder for reading watermark payload data from said digital image, and (c) a data input device which detects a physical characteristic of said person, said first and second computer systems cooperating to determine if said security document identifies said person.
Claim 12
Independent Claim
107 words
A system for validating a security document presented by a person, said security document containing a hidden digital watermark that contains watermark payload data, said system comprising: a first computer system coupled to a second computer system, the second computer system being remote from the first, said first computer system including (a) an optical scanner producing a digital image of said security document, (b) a digital watermark decoder for reading watermark payload data from said digital image, and (c) a data input device which detects a physical characteristic of said person, said first and second computer systems cooperating to determine if said security document identifies said person.
