Methods, Objects and Apparatus Employing Machine Readable Data
First Claim
Patent Images
1. A method comprising:
- determining an operating or performance characteristic associated with electronic circuitry;
determining information associated with the operating or performance characteristic;
utilizing a programmed electronic processor, hiding the information on or in a surface associated with the electronic circuitry so that the presence of the information is not readily apparent to a human observer of the surface, but the information can be obtained from the surface with visible light imaging, wherein the information is useable in determining whether the electronic circuitry is operating or functioning as expected.

Abstract
The present invention relates generally to steganography and data hiding. One claim recites an object including: electronic processing circuitry having an operating or performance metric associated therewith; and steganographic indicia carried by the object, the steganographic indicia is usable as an index to verify the operating or performance metric. Another claim recites an apparatus including: electronic memory; and machine-readable indicia usable as a registry index including data that provides an indication regarding an expected capacity of the electronic memory. Other combinations are described and claimed as well.
