Semiautomatic multifunction device-based validation of secure documents
A document validation system receives a scan of a certified document. The system identifies a security template for the document, prompts a user to enter a validation document into the scanning device, receives the validation document, uses the security template identify the location of one or more security elements on the certified document, and analyzes the validation document to identify expected content that should appear on the certified document at the security element locations. The system determines whether the expected content matches actual content of the scan at the security element locations and generates a report of the result.
1. A document validation system, comprising:
a processor; and
a non-transitory, computer-readable memory containing programming instructions that are configured to cause the processor to:
receive a scan image of a certified document,

prompt a user to provide a validation document,
receive the validation document in response to the prompt, wherein the validation document comprises content that should appear at one or more of the security element locations,
use the identified security template to identify the location of one or more security elements on the certified document that correspond to one or more of the security element locations of the identified security template,
apply the validation document to the identified security template to identify expected content that should appear on the certified document at the identified one or more security element locations on the certified document,
analyze the scan image to identify actual content that appears on the certified document at the identified one or more security element locations on the certified document,
determine whether the expected content matches the actual content, and output a report of the result to the user.

analyze the scan image of the certified document to identify one or more characteristics of the certified document in the scan image; and
use the identified characteristics to identify the security template.
4. The system of claim 1 , wherein the instructions to identify the security template comprise instructions to:
identify document content comprising one or more words, phrases, text formats, or data structures in the scan image;
and
apply a template matching technique to select, from the repository, a security template that corresponds to the identified document content.
5. The system of claim 1 , wherein the instructions to identify the security template comprise instructions to:
identify a barcode in the scan image;
and
select, from the repository, a security template that corresponds to the identified barcode.
6. The system of claim 1 , wherein the instructions to identify the security template comprise instructions to:
identify document content comprising fixed data in the scan image;
and
apply a template matching technique to select, from the repository, a security template that corresponds to the identified document content without reference to any variable data in the scan.
7. The system of claim 1 , wherein the instructions to apply the validation document to the identified security template to identify expected content that should appear on the certified document at the one or more security element locations on the certified document comprise instructions to extract descriptive material that includes each of the security element locations on the certified document and content elements that should appear at each of the security element locations on the certified document.
8. A method of validating a document, comprising:
by a processor, implementing programming instructions that are configured to cause the processor to implement a document validation process that comprises:
receiving a scan image of a certified document,
accessing a repository of security templates and identifying and retrieving, from the repository, a security template for the document, wherein the identified security template comprises one or more security element locations,
prompting a user to provide a validation document,
receiving the validation document in response to the prompt, wherein the validation document comprises content that should appear at one or more of the security element locations,
using the identified security template to identify the location of one or more security elements on the certified document that correspond to one or more of the security element locations of the identified security template,
applying the validation document to the identified security template to identify expected content that should appear on the certified document at the identified one or more security element locations on the certified document,
analyzing the scan image to identify actual content that appears on the certified document at the identified one or more security element locations on the certified document;
determining whether the expected content matches the actual content; and
outputting a report of the result to the user.
9. The method of claim 8 , wherein:
prompting the user to provide the validation document comprises prompting the user to enter the validation document in a scanning device; and
receiving the validation document comprises receiving the validation document via the scanning device.
10. The method of claim 8 , wherein identifying the security template comprises:
analyzing the scan image of the certified document to identify one or more characteristics of the certified document in the scan image; and
using the identified characteristics to identify the security template.
11. The method of claim 8 , wherein identifying the security template comprises:
identifying document content comprising one or more words, phrases, text formats, or data structures in the scan image;
and
applying a template matching technique to select, from the repository, a security template that corresponds to the identified document content.
12. The method of claim 8 , wherein identifying the security template comprises:
identifying a barcode in the scan image;
and
selecting, from the repository, a security template that corresponds to the identified barcode.
13. The method of claim 8 , wherein identifying the security template comprises:
identifying document content comprising fixed data in the scan image;
and
applying a template matching technique to select, from the repository, a security template that corresponds to the identified document content without reference to any variable data in the scan.
14. The method of claim 8 , wherein applying the validation document to the identified security template to identify expected content that should appear on the certified document at the security element locations comprises extracting descriptive material that includes each of the security element locations and content elements that should appear at each of the locations.
15. A document validation system, comprising:
a processor;
a scanning device configured to receive a certified document and generate a scan image of the certified document; and
a non-transitory, computer-readable memory containing programming instructions that are configured to cause the processor to:
receive the scan image of the certified document,
analyze the scan image to identify one or more characteristics of, or document content in, the certified document
access a repository of security templates and use the identified characteristics or document content to identify and retrieve, from the repository, a security template for the document, wherein the identified security template comprises one or more security element locations,
receive a validation document via the scanning device, wherein the validation document comprises content that should appear at one or more of the security element locations,
use the identified security template to identify the location of one or more security elements on the certified document that correspond to one or more of the security locations of the identified security template,
apply the validation document to the identified security template to identify expected content that should appear on the certified document at the identified one or more security element locations on the certified document,
analyze the scan image to identify actual content that appears on the certified document at the identified one or more security element locations on the certified document,
determine whether the expected content matches the actual content, and
output a report of the result.
16. The system of claim 15 , wherein the instructions to identify the security template comprise instructions to:
identify document content comprising one or more words, phrases, text formats, or data structures in the scan image; and
apply a template matching technique to select, from the repository, a security template that corresponds to the identified document content.
