Abstract

To alert parties to an alteration to a bar code (20) or a corresponding digital image (18), for example a digital photograph which the bar code (20) partially overlaps, the bar code (20) includes information about the digital image (18). The bar code (20) partially overlaps and is integrated into the image (18). The bar code (20) and the part thereof in the image (18) are compared for required identity. By providing such an alert, the present invention makes it very difficult to alter, for example, an identification card, an use it for unauthorized purposes.

Claims

1. A method for generating a representation of an object shown in a digital image, the method comprising:

generating said digital image, said digital image providing a visible identification of the object and containing image information, said image information regarding said digital image;

generating a bar code symbol that contains at least some of said image information, said bar code symbol having at least one of a bar and a space intersecting at least a portion of said digital image;

generating an underlying document including identifying information comprising at least said some information encoded in said bar code;

embedding said digital image and said bar code in said underlying document; and

determining color values of at least three picture elements in said digital image and determining corresponding coordinates of said at least three picture elements, and storing said color values and said coordinates in said bar code.

2. The method of claim 1, further comprising encrypting said information in said bar code.

3. The method of claim 1, wherein said digital image is a picture image comprised of picture elements.

4. A method for generating a representation of an object shown in a digital image, the method comprising:

generating said digital image, said digital image providing a visible identification of the object and containing image information, said image information regarding said digital image;

generating a bar code symbol that contains at least some of said image information, said bar code symbol having at least one of a bar and a space intersecting at least a portion of said digital image;

modifying color characteristics of picture elements in said portion of said digital image to integrate said bar code with said portion of said digital image;

generating an underlying document including identifying information comprising at least said some information encoded in said bar code; and

embedding said digital image and said bar code in said underlying document such that said portion of said digital image and said bar code are printed together.

5. The method of claim 4, wherein said step of modifying includes determining picture elements that intersect bars of said bar code and picture elements that intersect spaces of said bar code.

6. The method of claim 5, further comprising darkening said picture elements that intersect said bars of said bar code, and lightening said picture elements that intersect said spaces of said bar code.

7. The method of claim 6, wherein said step of lightening and said step of darkening provides at least 50% contrast between said bars and said spaces.

8. The method of claim 6, wherein said step of darkening comprises adding cyan and black from said picture elements, and said step of lightening comprises subtracting cyan and black from said picture elements.

9. An apparatus for generating a representation of an object shown in a digital image, the apparatus comprising:

a digital image generating module operable to generate a digital image providing a visible identification of said object and including image information regarding said digital image;

a bar code generating module operable to generate a bar code symbol having at least one of a bar and a space intersecting a portion of said digital image, and the bar code symbol containing at least some of said image information;

an underlying document generating module operable to generate an underlying document having at least some information encoded in said bar code printed thereon; and

a combining module operable to embed said digital image and said bar code in said underlying document such tat said bar code overlaps at least a portion of said digital image and said underlying document; and

a picture element gathering module operable to determine color values of at least three picture elements included in said digital image, operable to determine corresponding coordinates of said at least three picture elements, and to store said color values and said coordinates in said bar code.

10. The apparatus of claim 9, further comprising an encryption module operable to encrypt said information in said bar code.

11. The apparatus of claim 9, wherein said digital image is a picture image comprised of picture elements.

12. The apparatus of claim 9, wherein said bar code is at least one of a UCC/EAN 128, Codabar, Code 128, Code 39, Code93, UPC-A, UPC-E, JAN-13, ITF, ISSN, ITF and ISBN symbologies.

13. An apparatus for generating a representation of an object shown in a digital image, the apparatus comprising:

a digital image generating module operable to generate a digital image providing a visible identification of said object and including image information regarding said digital image;

a bar code generating module operable to generate a bar code symbol having at least one of a bar and a space intersecting a portion of said digital image, and the bar code symbol containing at least some of said image information;

a color modifying module operable to modify color characteristics of picture elements in said portion of said digital image to integrate said bar code with said portion of said digital image;

an underlying document generating module operable to generate an underlying document having at least some information encoded in said bar code printed thereon; and

a combining module operable to embed said digital image and said bar code in said underlying document such that said bar code overlaps at least a portion of said digital image and said underlying document such that said at least a portion of said digital image and said bar code are printed together.

14. The apparatus of claim 13, wherein said color modifying module further determines picture elements that intersect bars of said bar code and picture elements that intersect spaces of said bar code.

15. The apparatus of claim 13, wherein said color modifying module further darkens said picture elements that intersect said at least one bars of said bar code, and lightens said picture elements that intersect said spaces of said bar code.

16. The apparatus of claim 15, wherein said color modifying module provides at least 50% contrast between said bars and said spaces.

17. The apparatus of claim 15, wherein said color modifying module darkens said picture elements by adding cyan and black to said picture elements, and lightens said picture elements by subtracting cyan and black from said picture elements.
