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.

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.

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. - View Dependent Claims (5, 6, 7, 8)

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. - View Dependent Claims (10, 11, 12)
