Abstract
Abstract A highly secure personal identification related document is achieved by having an area which contains machine readable information and also having a printed region having embedded data in the image printed thereon. The machine readable information as recorded has been encoded using a secure hash algorithm. For legitimate personal identification related documents, the machine readable data and the embedded data are identical information. The personal identification related document is used in conjunction with a reader system which includes a reader for the machine readable data, an optical scanner for scanning the image and data embedded therein, and a processor. The machine readable data is delivered to the processor which applies the secure hash algorithm thereto to generate a first data set. The digitized image data retrieved with the optical scanner is also delivered to the processor and the embedded data is retrieved therefrom to generate a second data set. The two data streams are then passed to a comparator to determine if there is an adequate match to verify authenticity of the document.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A personal identification related document reader system comprising: means for reading a machine readable area of a personal identification related document; an optical scanner for scanning a printed image area of the personal identification related document; means for extracting data embedded with an image in the printed image area; a hash algorithm for deriving information from the machine readable area; means for comparing the information derived from the machine readable area to the extracted data embedded within the printed image area; and an indicator device which informs a user if the information derived from the machine readable area and the extracted data embedded within the printed image area are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.
Claim 2
Dependent Claim
125 words
A personal identification related document reader system comprising: means for reading a machine readable area of a personal identification related document; an optical scanner for scanning a printed image area of the personal identification related document; means for extracting data embedded with an image in the printed image area; a hash algorithm for deriving information from the machine readable area; means for comparing the information derived from the machine readable area to the extracted data embedded within the printed image area; and an indicator device which informs a user if the information derived from the machine readable area and the extracted data embedded within the printed image area are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.
Claim 3
Dependent Claim
22 words
A personal identification related document reader system as recited in claim 1 wherein: the machine readable information is in a magnetic strip.
Claim 4
Dependent Claim
23 words
A personal identification related document reader system as recited in claim 1 wherein: the machine readable information is in a two-dimensional bar code.
Claim 5
Dependent Claim
22 words
A personal identification related document reader system as recited in claim 1 wherein: the machine readable information is in an integrated circuit.
Claim 6
Dependent Claim
22 words
A personal identification related document reader system as recited in claim 1 wherein: the machine readable information is in a data glyph.
Claim 7
Dependent Claim
30 words
A personal identification related document as recited in claim 1 wherein: the printed image information in the printed region is an image of the holder the personal identification related document.
Claim 8
Dependent Claim
21 words
A personal identification related document reader system as recited in claim 1 further comprising: a personal identification related document transport system.
Claim 9
Dependent Claim
22 words
A personal identification related document reader system as recited in claim 7 wherein: said personal identification related document is a transaction card.
Claim 10
Independent Claim
153 words
A method for verifying authenticity of a personal identification related document having a hash algorithm encoded first data set recorded on a machine readable area and a second data set derived from the first data set embedded in an image printed on a printed region, the method comprising the steps of: scanning the image in the printed region; extracting the second data set from the image in the printed region; reading the encoded first data set; decoding the hash algorithm encoded first data set; deriving the second data set from the first data set of said decoding step; comparing the second data set from said deriving step with the second data set from said extracting step; and determining whether the second data set from said deriving step and the first data set from said extracting step are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.
Claim 11
Independent Claim
153 words
A method for verifying authenticity of a personal identification related document having a hash algorithm encoded first data set recorded on a machine readable area and a second data set derived from the first data set embedded in an image printed on a printed region, the method comprising the steps of: scanning the image in the printed region; extracting the second data set from the image in the printed region; reading the encoded first data set; decoding the hash algorithm encoded first data set; deriving the second data set from the first data set of said decoding step; comparing the second data set from said deriving step with the second data set from said extracting step; and determining whether the second data set from said deriving step and the first data set from said extracting step are within a predetermined level of agreement, the predetermined level of agreement being less than 100 percent.
Claim 12
Dependent Claim
28 words
A method as recited in claim 9 wherein: the image to be printed onto the printed region is an image of the holder the personal identification related document.
