1. An apparatus comprising:
- an optical imager for capturing image or video data associated with a physical object, the physical object comprising a plurality of randomly or pseudo-randomly occurring features, the physical object further comprising indicia provided thereon, the indicia conveying expected characteristics of the features including expected spatial positioning information relative to the physical object;
a display;
means for analyzing image or video data captured by the optical imager to obtain actual characteristics of the features, the actual characteristics of the features comprising spatial positioning information for the features on the physical object;
means for analyzing the image or video data to obtain the expected characteristics of the features;
means for, based at least on the expected characteristics and the actual characteristics of the features, providing user feedback via the display corresponding to an expected spatial positioning of the features relative to the physical object, the user feedback also corresponding to an actual spatial positioning of the features.

Abstract
The present disclosure relates generally to physical object authentication. In some embodiments, methods and apparatus relate to physical object authentication through comparison of randomly or pseudo-randomly occurring features with expected features. In some cases digital watermark or other indicia is used to convey the expected features. Of course, other combinations, embodiments and features are disclosed.
