Abstract

Apparatus and a method are disclosed for reading documents, such as identity documents, including passports, and documents of value, to obtain and verify information recorded thereon, and to read and/or detect security information thereon to determine if such documents are counterfeit or have been altered.

Claims

1. Apparatus for verifying documents to determine if they are genuine, counterfeit, or if they have been altered, each document having a number of attributes, said apparatus including a plurality of different light sources that are sequentially energized to create multiple, different images of a document being verified, and said multiple, different images contain the attributes of a document being verified, and said apparatus comprising:

means for checking a first one of said multiple images of a document for a first type of information therein;

means responsive to said first type of information for determining the type of document that is being verified;

a first list of attributes for each of a plurality of different types of documents that may be verified using said apparatus;

means for analyzing said multiple, different images for said attributes

means for comparing the attributes in said first list for the type of document that is being verified with attributes actually on said first document as contained in said multiple images to determine if said first document is genuine, counterfeit, or if it has been altered; and

means for providing a first indication that said first document is genuine, counterfeit, or has been altered.

2. The apparatus in accordance with claim 1 wherein said means for analyzing comprises:

a first list of attributes for each of a plurality of different types of documents that may be verified using said apparatus; and

means for comparing the attributes in said first list for the type of document that is being verified with attributes actually on said first document as contained in said multiple images.

3. The apparatus in accordance with claim 2 wherein said means for generating multiple, different images of a first document comprises means for sequentially energizing said plurality of different light sources.

4. The apparatus in accordance with claim 2 further comprising a second list of security features for each of said plurality of different types of documents that may be verified by said apparatus, said security features being used to determine if said first document is genuine, counterfeit or has been altered.

5. The apparatus in accordance with claim 4 further comprising means for comparing the security features in said second list for the type of document that is being verified with security features actually on said first document as contained in said multiple images.

6. The apparatus in accordance with claim 5 further comprising means for providing a second indication to an operator of said apparatus that said first document is counterfeit or has been altered.

7. The apparatus in accordance with claim 6 further comprising:

a third list of named parties who must be detained or investigated further; and

means for comparing the named parties on said third list with the name on said first document.

8. The apparatus in accordance with claim 7 further comprising means for providing an indication to an operator of said apparatus that the party who carries said first document is on said third list.

9. The apparatus in accordance with claim 2 wherein said means for generating multiple, different images of said first document comprises a camera for creating an electronic image of said document when each of said plurality of different light sources is energized.

10. The apparatus in accordance with claim 9 wherein said means for generating multiple, different images of said first document further comprises means for digitizing said electronic image of said document output from said camera.

11. The apparatus in accordance with claim 2 comprising optical means located in a first path between said means for generating multiple, different images and said first document, said optical means reflecting light from said plurality of different light sources along said first path and onto said first document, and light reflected from said first document travels along said first path and through said optical to said means for generating multiple, different images of said first document.

12. The invention in accordance with claim 11 wherein ones of said plurality of different light sources generate light that is visible, and others ones of said plurality of different light sources generate light that is invisible.

13. The invention in accordance with claim 2 wherein ones of said plurality of different light sources generate light that is visible, and others ones of said plurality of different light sources generate light that is invisible.

14. The apparatus in accordance with claim 2 further comprising a second list of security features for each of said plurality of different types of documents that may be verified by said apparatus, said security features being used to determine if said first document is genuine, counterfeit or has been altered.

15. The apparatus in accordance with claim 14 further comprising means for comparing the security features in said second list for the type of document that is being verified with security features actually on said first document as contained in said multiple images.

16. The apparatus in accordance with claim 15 further comprising means for providing a second indication to an operator of said apparatus that said first document is genuine, counterfeit or has been altered.

17. The apparatus in accordance with claim 16 further comprising:

a third list of named parties who must be detained or investigated further; and

means for comparing the named parties on said third list with the name on said first document.

18. The apparatus in accordance with claim 17 further comprising means for providing an indication to an operator of said apparatus that the party who carries said first document is on said third list.

19. A method for verifying documents to determine if they are genuine, counterfeit, or if they have been altered, each document having a number of attributes, and a plurality of different light sources are sequentially energized to create multiple, different images of a document being verified, and said multiple, different images contain the attributes of a document being verified, said method comprising the steps of:

checking a first one of said multiple images of a document that is being verified to determine what type of document it is;

comparing attributes stored in a first list of attributes for each of a plurality of different types of documents that may be verified with attributes actually on said first document as contained in said multiple images to determine if said first document is genuine, counterfeit, or if it has been altered; and

providing a first indication that said first document is genuine, counterfeit, or has been altered.

20. The method in accordance with claim 19 wherein said step of analyzing said multiple images for said attributes to verify a document comprises the step of comparing attributes stored in a first list for the type of document that is being verified with attributes actually on said first document as contained in said multiple images.

21. The method in accordance with claim 20 wherein said step of analyzing said multiple images to verify a document further comprises the steps of:

comparing security features stored in a second list for the type of document that is being verified with security features actually on said first document as contained in said multiple images, said security features being used to determine if said first document is genuine, counterfeit or has been altered; and

providing a second indication that said first document is genuine, counterfeit or has been altered.

22. The method in accordance with claim 21 further comprising the steps of:

comparing the persons name on said first document with names stored in a third list of named parties who must be detained or investigated further; and

providing an indication to an operator of said verifier apparatus that the party who carries said document is on said third list.

23. The method in accordance with claim 22 wherein said step of generating multiple, different images of said first document comprises the step of illuminating said first document with certain ones of said different light sources along an optical path that is identical to the optical path that light travels when reflected from said first document.
