System and method for production and authentication of original documents
First Claim
1. A system for authentication of a counterfeit-resistant document, comprising:
- (a) means for receiving an apparently non-deterministic characteristic of a recording medium of the document;
(b) means for receiving a document content of the document;
(c) means for storing the apparently non-deterministic characteristic and document content in association with each other; and
(d) means for comparing the stored description of the apparently non-deterministic characteristic and document content with an observed apparently non-deterministic characteristic and document characteristic.

Abstract
A system and method for authenticating documents and content thereof. A counterfeit resistant document recording medium is provided, having thereon a predefined unique document identifier and at least one security feature. The recording medium is thereafter imprinted with document content, which typically varies between documents. The document content is stored in a database, indexed by an associated document identifier. The document may then be authenticated by checking the security feature and comparing the stored document content with a perceived document content. The system provides a number of opportunities for commercial exploitation, including sales of identified recording media, recording of information in a database, on-line authentication transactions, differential accounting for document validations and counterfeit identifications, imprinting devices, authentication devices, and the like. The system prevents counterfeiting of valuable documents through casual means by providing both physical and logical security.

50. A method for authentication of a counterfeit resistant document, comprising the steps of:
-
(a) automatically describing an apparently non-deterministic characteristic of a recording medium of the document;
(b) receiving a document content of the counterfeit resistant document;
(c) storing the description of the apparently non-deterministic characteristic and document content in association with each other; and

59. A method for providing document security, comprising the steps of:
-
(a) providing a document to be authenticated, having predefined document content;
(b) providing a serialized piece of paper currency;
(c) physically associating the document and the paper currency; and
(d) storing document content in association with the serial number of the paper currency. - View Dependent Claims (60)

61. An authentication system comprising:
-
(a) a plurality of media, each having a plurality of counterfeit-resistant non-deterministic elements;
(b) a detector, detecting said elements;
(c) a storage system for storing a description of said detected elements;
(d) a recording system for recording a content on said medium;
(e) means for storing said content; and
(f) means for comparing a set of detected elements and stored content with a set of observed elements of the media and content to authenticate the media and content. - View Dependent Claims (62, 63, 64, 65, 66, 67, 68)

69. An authentication system comprising:
-
(a) an authentication certificate having a counterfeit resistant element and a document content;
(b) a secure code associated with the authentication certificate defining an apparently non-deterministic characteristic of the counterfeit resistant element and a digital signature of the document content;
(c) a device for reading the apparently non-deterministic characteristic; and
(d) a processor for comparing the read apparently non-deterministic characteristic of the authentication certificate and content thereof with the associated secure code to determine an authenticity of the authentication certificate, the authenticity being associated with a reliability thereof, based on;
stochastic variations in the apparently non-deterministic characteristic, and stochastic variations in the received input used for generation of the associated secure code. - View Dependent Claims (70, 71)
