Abstract
Abstract An identification system includes means for scanning an identity pattern in a predetermined manner and correlating previously-obtained recognition data with information derived therefrom to determine a positive identification. In obtaining recognition data, the identity pattern is scanned and digitized in a predetermined manner, and then analyzed and sorted to provide prominent information most likely to be recognized in subsequent identity verifications with the original recognition pattern. In this manner, unique recognition data for each identity pattern is stored and is available for rapid retrieval and correlation when the original identity pattern is presented.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A method of providing identification of a person by the characteristics of his palm, comprising the steps of: scanning by opto-electronic means the palm of said person and producing an analog signal proportional to levels of light of said palm; converting said analog signal to digital picture data representative of a substantially complete picture of said palm; storing said digital picture data in a picture storage device; electronically analyzing said picture data and selecting therefrom recognition data corresponding to prominent characteristics of said recognition pattern, said recognition data including point location, line quality, and line direction of pattern lines of said palm; and storing said recognition data to provide said identification.
Claim 2
Independent Claim
111 words
A method of providing identification of a person by the characteristics of his palm, comprising the steps of: scanning by opto-electronic means the palm of said person and producing an analog signal proportional to levels of light of said palm; converting said analog signal to digital picture data representative of a substantially complete picture of said palm; storing said digital picture data in a picture storage device; electronically analyzing said picture data and selecting therefrom recognition data corresponding to prominent characteristics of said recognition pattern, said recognition data including point location, line quality, and line direction of pattern lines of said palm; and storing said recognition data to provide said identification.
Claim 3
Dependent Claim
27 words
A method in accordance with claim 1 further including the step of passing said analog signal through a differentiating network to enhance details of said recognition data.
Claim 4
Dependent Claim
39 words
A method in accordance with claim 1 wherein said step of analyzing said picture data further includes ranking said recognition data in order from highest quality to lowest quality in accordance with the prominence of characteristics of said palm.
Claim 5
Dependent Claim
39 words
A method in accordance with claim 1 further including the steps of testing said stored recognition data with new picture data to determine a correlation therebetween, counting correlation mismatch errors, and providing a decision signal to a utilization device.
Claim 6
Independent Claim
126 words
An apparatus for identification of a recognition pattern, comprising: means for scanning an object having a recognition pattern thereon and producing an analog signal proportional to levels of light of the scanned object; means for converting said analog signal to digital picture data representative of a substantially complete picture of said recognition pattern; first storage means for storing said digital picture data in storage locations representative of graphic point locations of said picture; analyzer means coupled to said first storage means for analyzing said picture data and selecting therefrom recognition data corresponding to prominent characteristics of said recognition pattern, said recognition data including point location, line quality, and line direction of pattern lines; and second storage means for storing said recognition data to provide said identification.
Claim 7
Independent Claim
126 words
An apparatus for identification of a recognition pattern, comprising: means for scanning an object having a recognition pattern thereon and producing an analog signal proportional to levels of light of the scanned object; means for converting said analog signal to digital picture data representative of a substantially complete picture of said recognition pattern; first storage means for storing said digital picture data in storage locations representative of graphic point locations of said picture; analyzer means coupled to said first storage means for analyzing said picture data and selecting therefrom recognition data corresponding to prominent characteristics of said recognition pattern, said recognition data including point location, line quality, and line direction of pattern lines; and second storage means for storing said recognition data to provide said identification.
Claim 8
Dependent Claim
28 words
An apparatus in accordance with claim 5 further including an enhance circuit interposed between said scanning means and said converting means, said enhance circuit comprising a differentiating network.
Claim 9
Dependent Claim
66 words
An apparatus in accordance with claim 5 wherein said first storage means comprises a picture storage array having picture elements corresponding to said graphic point locations of said picture; and said analyzer means includes means for sequentially inspecting said picture elements to determine starting points for developing pattern lines, and further includes means for evaluating a plurality of contiguous picture elements to develop said pattern lines.
Claim 10
Dependent Claim
31 words
An apparatus in accordance with claim 7 wherein said analyzer means further includes means for ranking said recognition data in order of prominence of details from highest quality to lowest quality.
Claim 11
Dependent Claim
26 words

Claim 12
Dependent Claim
46 words
An apparatus in accordance with claim 5 further including test means for testing said recognition data stored in said second storage means with new picture data to determine a correlation therebetween, and utilization means responsive to said correlation for indicating verification or rejection of said identification.
Claim 13
Dependent Claim
58 words
An apparatus in accordance with claim 10 wherein said test means comprises a plurality of read-only memories containing program steps for determining the correlation between said recognition and said picture data and for counting correlation mismatch errors, said test means further comprising decision circuit means responsive to said correlation and said mismatch errors for making an identification decision.
