Abstract

A system and method of imaging a document wherein a watermark is created and applied to the image. The watermark includes identifying information and may include information to determine whether the image has been altered since its creation. In a system where a single document (such as a check) is used to create multiple images (in the case of a check, an image of the front and back may be created in different manners, such as with different resolution or different levels of grey-scale). The use of a single watermark for multiple images of the same check can be used to determine that the multiple images are in fact of a single document and not of different documents, either though mistake or deception. A digitized image of the document is stored and a watermark associated with the document is generated and overlaid on the image to create a watermark on the image of the document for later use and processing.

Claims

1. A system for processing a document including data, the system comprising:

a system for capturing multiple images of the same document;

a system for generating a watermark associated with the document;

a merging apparatus for combining the watermark with more than one of the multiple images, whereby the multiple images each include a watermark associated with the document; and

storage for storing the combined images of the document with the watermark associated with the document.

2. The system of claim 1 wherein the system further includes a system for reading some of the data associated with the document, with the watermark including some of the data read from the document.

3. The system for processing images of the type described in claim 1 wherein the system further includes a first image camera for receiving and digitizing the front of the document creating a first image and a second image camera for receiving and digitizing the back of the document creating a second image, wherein the same watermark is applied to the first and second images.

4. The system for processing images of the type described in claim 3 wherein at least one of the first and second image cameras captures more than one image of the same document and the system for applying the watermark applies the same watermark to the more than one image by the at least one of the first and second image cameras.

5. The system for processing images of the type described in claim 1 wherein the system for applying watermarks applies a first watermark portion which is visible and a second watermark portion which is not visible.

6. A set of images associated with a document which has passed by at least one image camera, the set of images including a first image and a second image both associated with the document, said first and second images each including an added watermark which is unique to the document, whereby an image associated with the document can be differentiated from an image which is associated with another document.

7. A set of images of the type described in claim 6 wherein each of the images includes a visible watermark and an invisible watermark.

8. A set of images of the type described in claim 6 wherein each of the images includes a first watermark portion which has a company identity and a second watermark portion which includes variable information for that document.

9. A set of images of the type described in claim 8 wherein the variable information includes the date on which the image was processed.

10. A set of images of the type described in claim 8 wherein the variable information includes a unique sequence number associated with the document.

11. A set of images of the type described in claim 8 wherein the company identity is the identity of the company processing the document.

12. A method of processing a document comprising the steps of:

generating a first image of the document;

creating a watermark for the document

combining the image of the document with the created watermark to create a composite image of the document with the watermark; and

generating a second image of the document and applying a watermark to the second image which indicates its association with the first image and its watermark, whereby the first and second images from the same document may be associated together by virtue of the watermark applied to the first and second images.

13. The method of claim 12 further including the step of creating a watermark with a visible portion and an invisible portion.

14. The method of claim 12 further including the step of creating a watermark with a first common portion and a second unique portion, with the common portion being applied to different documents and the unique portion being applied only to images associated with a single document.

15. The method of claim 14 wherein the step of creating a watermark with a unique portion includes the step of including the date of processing in the watermark.

16. The method of claim 14 wherein the step of creating a watermark with a unique portion includes the step of including a sequence number in the watermark.

17. A method of preparing a set of images related to a single document, the steps of the method comprising:

using a camera to create multiple images of the same document;

creating a unique watermark for the document;

applying the same unique watermark to each of the multiple images of the same document, whereby the multiple images of a single document will be apparent from the watermark and images associated with a different document will be distinguishable from the images associated with a single document in that the different images will have differing watermarks.

18. A method including the steps of claim 17 wherein the step of applying the same unique watermark to each of the multiple images includes the step of including a sequence number in the watermark.

19. A method including the steps of claim 17 wherein the step of applying the same unique watermark to each of the multiple images includes the step of including the date of processing in the unique watermark.

20. A method including the steps of claim 17 wherein the step of applying a watermark includes the step of applying a visible watermark and an invisible watermark.
