Abstract

Methods and systems are provided for capturing written information from an information field of a document using a computer system. A document may be provided to the computer system. The document may include at least one information field. In one embodiment, a method includes assessing whether writing in an information field approximately matches a writing profile representation from at least one information field from at least one other document and associating the information field with the text representation corresponding to a matching writing profile representation.

Claims

1. A method, comprising:

providing a document to a computer system, wherein the document comprises a payee field;

assessing, using the computer system, whether writing in the payee field approximately matches a writing profile representation,

wherein the matching writing profile representation is associated with a corresponding text representation of a payee name in a computer processable format in memory on the computer system;

associating the payee field with the text representation corresponding to the matching writing profile representation;

assessing, using the computer system, at least one cross field relationship between two fields of the document; and

performing one or more fraud tests of the document based at least in part on information captured from the payee field of the document.

2. The method of claim 1, wherein providing the document to the computer system comprises providing images of the document to the computer system.

3. The method of claim 1, wherein at least one writing profile representation is obtained from a valid document.

4. The method of claim 1, wherein the document comprises a payment instrument, and wherein the writing is writing from at least one account owner of an account of the payment instrument.

5. The method of claim 1, wherein providing the document to the computer system comprises obtaining images of writing of at least one information field.

6. The method of claim 1, wherein the writing from the payee field comprises an image.

7. The method of claim 1, further comprising creating a mathematical representation of the writing in the payee field.

8. The method of claim 1, wherein the writing comprises at least one image.

9. The method of claim 1, wherein the writing comprises at least one type of handwritten information.

10. The method of claim 1, wherein the writing comprises at least one type of written information, and wherein at least one type of written information comprises a word type.

11. The method of claim 1, wherein the writing comprises at least one type of written information, and wherein at least one type of written information comprises a character type.

12. The method of claim 1, wherein the writing comprises at least one global feature of the writing.

13. The method of claim 1, wherein the writing comprises at least one local feature of the writing.

14. The method of claim 1, wherein the writing comprises at least one syntax pattern.

15. The method of claim 1, wherein the writing comprises at least one lexicon name for at least one information field.

16. The method of claim 1, wherein at least one writing profile representation comprises at least one mathematical representation.

17. The method of claim 1, wherein at least one writing profile representation comprises at least one image.

18. The method of claim 1, wherein at least one writing profile representation comprises at least one type of written information.

19. The method of claim 1, wherein at least one writing profile representation comprises at least one writing variant of an example of at least one type of written information.

20. The method of claim 1, wherein at least one writing profile representation comprises at least one writing variant of an example of at least one type of written information, and wherein at least one type of written information comprises a word type.

21. The method of claim 1, wherein at least one writing profile representation comprises at least one writing variant of an example of at least one type of written information, and wherein at least one type of written information comprises a character type.

22. The method of claim 1, wherein at least one writing profile representation comprises at least one writing variant of an example of at least one type of written information, and further comprising determining at least one of the variants with a cluster algorithm.

23. The method of claim 1, wherein at least one writing profile representation comprises at least one global characteristic of the writing.

24. The method of claim 1, wherein at least one writing profile representation comprises at least one local characteristic of the writing.

25. The method of claim 1, wherein at least one writing profile representation comprises at least one variant of a syntax pattern.

26. The method of claim 1, wherein at least one writing profile representation comprises at least one lexicon name for at least one information field.

27. The method of claim 1, wherein the writing profile representation is from at least one payee field from at least one other document.

28. The method of claim 1, further comprising assessing whether the payee in the payee field of the document matches one or more payees in a lexicon of payees.

29. The method of claim 1, wherein the at least one cross field relationship comprises a relationship between a payee field and at least one other field of the document.

30. The method of claim 1, wherein the at least one cross field relationship comprises a relationship between an account number and a payee name.

31. The method of claim 1, wherein the cross field relationship comprises a relationship between a payee name and a legal amount or between a payee name and a courtesy amount.

32. A system, comprising:

a CPU;

a data memory coupled to the CPU; and

a system memory coupled to the CPU, wherein the system memory is configured to store one or more computer programs executable by the CPU, and wherein the computer programs are executable to implement a method comprising;

providing a document to the computer system, wherein the document comprises a payee field;

assessing whether writing in the payee field approximately matches a writing profile representation,

wherein the matching writing profile representation is associated with a corresponding text representation of a payee name in a computer processable format in memory on the computer system;

associating the payee field with the text representation corresponding to the matching writing profile representation;

assessing at least one cross field relationship between two fields of the document; and

performing one or more fraud tests of the document based at least in part on information captured from the payee field of the document.

33. A computer readable storage medium comprising program instructions, wherein the program instructions are computer-executable to implement a method comprising:

providing a document to a computer system, wherein the document comprises a payee field;

assessing whether writing in the payee field approximately matches a writing profile representation,

wherein the matching writing profile representation is associated with a corresponding text representation of a payee name in a computer processable format in memory on the computer system; and

associating the payee field with the text representation corresponding to the matching writing profile representation;

assessing at least one cross field relationship between two fields of the document; and

performing one or more fraud tests of the document based at least in part on information captured from the payee field of the document.

34. A method, comprising:

providing a document to a computer system, wherein the document comprises a payee field;

assessing, using the computer system, whether writing in the payee field approximately matches a writing profile representation,

wherein the matching writing profile representation is associated with a corresponding text representation of a payee name in a computer processable format in memory on the computer system;

associating the payee field with the text representation corresponding to the matching writing profile representation;

assessing, using the computer system, whether the payee in the payee field of the document matches one or more entries in a list of suspicious payees; and

performing one or more fraud tests of the document based at least in part on information captured from the payee field of the document.

36. The method of claim 34, wherein the list of suspicious payees comprises one or more payee names frequently involved in transactions with fraud risk.

35. A method, comprising:

providing a document to a computer system, wherein the document comprises a payee field, wherein the document comprises a payment instrument, and wherein the writing is writing from at least one account owner of an account of the payment instrument;

assessing, using the computer system, whether writing in the payee field approximately matches a writing profile representation,

wherein the matching writing profile representation is associated with a corresponding text representation of a payee name in a computer processable format in memory on the computer system;
