1. A method comprising:
- determining an operating or performance characteristic associated with an apparatus;
determining a numeric expression associated with the operating or performance characteristic;
steganographically hiding the numeric expression on or in the apparatus so that the presence of the numeric expression is not readily discernable to a human viewer of the apparatus, but the numeric expression can be obtained from the apparatus with visible light imaging, wherein the numeric expression is useable in determining whether the apparatus is operating or functioning as expected.
