Abstract

In one approach, a method includes: capturing an image of a document using a camera of a mobile device; performing optical character recognition (OCR) on the image of the document; extracting data of interest from the image based at least in part on the OCR; and validating the extracted data of interest against reference information stored on the mobile device. In another embodiment, a method includes: capturing an image of a document using a camera of a mobile device; performing optical character recognition (OCR) on the image of the document; extracting data of interest from the image based at least in part on the OCR; and validating authenticity of the document based on comparing some or all of the extracted data of interest to reference information stored on the mobile device.

Claims

1. A computer-implemented method, comprising:

receiving an image of a document at a mobile device;

performing optical character recognition (OCR) on the image of the document;

extracting data of interest from the image based at least in part on the OCR; and

validating the extracted data of interest against reference information stored on the mobile device;

wherein the validation comprises device-based validation;

wherein the device-based validation comprises normalizing the extracted data of interest to match a predetermined format; and

wherein the reference information comprises an immutable or substantially immutable identifier of the mobile device.

2. The method as recited in claim 1, further comprising determining at least some of the data of interest were imperfectly extracted from the image;

and

validating the imperfectly extracted data of interest against reference information stored on the mobile device.

3. The method as recited in claim 2, wherein validating the imperfectly extracted data of interest further comprises at least one of:

correcting OCR errors in the imperfectly extracted data of interest based in whole or in part on at least one of the reference information and predefined business rules, and

normalizing data from the document based at least in part on at least one of the reference information and the predefined business rules.

4. The method as recited in claim 1, wherein the validation comprises expectation-based validation.

5. The method as recited in claim 1, wherein the predetermined format is a workflow-specific format.

6. The method as recited in claim 1, wherein the reference information comprises an immutable or substantially immutable identifier of the mobile device.

7. The method as recited in claim 6, wherein the immutable or substantially immutable identifier comprises one or more of:

a mobile device name, a telephone number associated with the mobile device, a mobile device MAC address, a mobile subscription identification number (MSIN), a mobile equipment identifier (MEID), and an international mobile equipment identity (IMEI); and

wherein the validating comprises comparing the extracted data of interest to the immutable or substantially immutable identifier.

8. The method as recited in claim 1, wherein the reference information comprises contact information stored on the mobile device;

and

wherein the reference information further comprises an immutable or substantially immutable identifier of the mobile device, and wherein the contact information is stored on the mobile device in association with the immutable or substantially immutable identifier.

9. The method as recited in claim 1, wherein the validation comprises device-based identity validation;

and wherein the device-based identity validation includes determining whether an individual conducting a transaction involving the extracted data of interest is an owner of a mobile device used to capture the image of the document.

10. The method as recited in claim 1, further comprising validating authenticity of the document based on determining an immutable identifier associated with a mobile device used to capture the image of the document matches an immutable identifier of the mobile device that received the image.

11. The method as recited in claim 1, further comprising:

determining the data of interest were imperfectly extracted from the image; and

correcting the imperfectly extracted data of interest using the reference information stored on the mobile device.

12. A computer-implemented method, comprising,

receiving an image of a document at a mobile device;

performing optical character recognition (OCR) on the image of the document

extracting data of interest from the image based at least in part on the OCR; and

validating the extracted data of interest against reference information stored on the mobile device; and

validating authenticity of the document based on determining an immutable identifier associated with a mobile device used to capture the image of the document matches an immutable identifier of the mobile device that received the image, wherein the validating the authenticity of the document further comprises;

generating at least one hypothesis mapping the document to reference information stored on the mobile device, wherein generating the at least one hypothesis is based at least in part on one or more of;

textual information from the document;

the reference information; and

predefined business rules;

determining a validity of the document based on the at least one hypothesis; and

outputting an indication of the determined validity.

13. A computer-implemented method, comprising:

receiving an image of a document at a mobile device;

performing optical character recognition (OCR) on the image of the document;

extracting data of interest from the image based at least in part on the OCR; and

validating the extracted data of interest against reference information stored on the mobile device; and

validating the document from which the data of interest were extracted, wherein validating the extracted data of interest and validating the document from which the data of interest were extracted comprise independent validation processes;

wherein determining the validity of the document comprises expectation-based validation and device-based validation; and

wherein the reference information comprises an immutable or substantially immutable identifier of the mobile device.

14. A method, comprising:

capturing an image of a document using a camera of a mobile device;

performing optical character recognition (OCR) on the image of the document;

extracting data of interest from the image based at least in part on the OCR; and

validating authenticity of the document based on comparing some or all of the extracted data of interest to reference information stored on the mobile device;

wherein the reference information comprises one or more immutable or substantially immutable device identifiers selected from a group consisting of;

a mobile device name, a telephone number associated with the mobile device, a mobile device MAC address, a mobile subscription identification number (MSIN), a mobile equipment identifier (MEID), and an international mobile equipment identity (IMEI); and

wherein the validating further comprises;

generating at least one hypothesis mapping the document to reference information stored on the mobile device;

determining a validity of the document based on the at least one hypothesis; and

outputting an indication of the determined validity; and

wherein generating the at least one hypothesis is based at least in part on one or more of;

textual information from the document

the reference information; and

predefined business rules.

15. The method as recited in claim 14, further comprising:

determining the data of interest were imperfectly extracted from the image; and

correcting the imperfectly extracted data of interest using the reference information stored on the mobile device.

16. The method as recited in claim 14, further comprising normalizing the extracted data of interest based at least in part on the reference information and one or more predefined business rules.

17. A method, comprising:

receiving a request to perform an operation using a mobile device, the operation requiring authentication;

in response to receiving the request, capturing an image of a document using the mobile device, the document depicting identifying information corresponding to a person;

extracting the identifying information corresponding to the person from the image of the document using the mobile device;

validating the identifying information extracted from the image of the document and corresponding to the person against identifying information stored on the mobile device, the identifying information stored on the mobile device corresponding to an owner of the mobile device;

determining an immutable identifier associated with the mobile device used to capture the image of the document;

validating the immutable identifier associated with the mobile device used to capture the image of the document with an immutable identifier associated with the identifying information stored on the mobile device and corresponding to the owner of the mobile device; and
