Abstract

Data defining several different information-carrying patterns can be stored on mass storage of a computer workstation and serve as a library of design elements for future designs. The same user-interface techniques that are employed to pick colors in image-editing software (e.g. Adobe Photoshop) and fill textures in presentation programs (e.g. Microsoft PowerPoint) can similarly be used to present a palette of information patterns to a security document designer. Clicking on a visual representation of the desired pattern makes the pattern available for inclusion in a security document being designed (e.g. filling a desired area). A great variety of other features and arrangements are also detailed.

Claims

1. A method comprising the acts:

presenting on a computer screen device a graphical user interface associated with a graphics editing program, the user interface including a palette;

receiving input from a user picking a selection from the palette;

adding an element to a graphical work displayed on the screen device in accordance with the picked selection;

wherein the palette presents at least one information-carrying pattern.

2. The method of claim 1 wherein the information-carrying pattern comprises a digital watermark pattern.

3. The method of claim 1 wherein the information-carrying pattern encodes a plural-bit payload.

4. The method of claim 3 wherein the payload comprises 128 bits.

5. The method of claim 1 wherein the adding comprises filling a region.

6. The method of claim 1 wherein the palette presents plural different information-carrying patterns.

7. The method of claim 1 wherein the information-carrying pattern comprises a visible pattern.

8. The method of claim 7 wherein the information-carrying pattern comprises a glyph pattern.

9. In a computer readable medium that stores software instructions for configuring a programmable computer system to serve as a graphics editing system, including instructions by which the system presents a palette of art elements from which a user can pick in composing or editing a graphical artwork, an improvement wherein the palette includes one or more patterns encoding machine-readable plural-bit information.

10. A digital artwork system comprising computer hardware configured in accordance with software instructions, which presents a palette of patterns from which a user chooses to select a desired pattern for incorporation into the artwork to encode artwork with plural-bit digital information.
