Claims23
A method comprising:
- obtaining captured image data or video data associated with a physical object, the physical object comprising a plurality of features, the plurality features comprising a plurality of lines, the plurality of lines comprising modulations forming a pattern used for authenticating the physical object, the modulations carried by line modulations or angle modulations;
- evaluating the captured image data or video data to obtain actual characteristics of the plurality of features, the actual characteristics of comprising spatial positioning information for the pattern used for authenticating the physical object;
- obtaining expected characteristics of pattern used for authenticating the physical object;
- based at least on the expected characteristics and the actual characteristics, controlling display of user feedback on a display carried by a mobile device, the user feedback facilitating a determination of authenticity of the physical object.

A method comprising:
- obtaining captured image data or video data associated with a physical object, the physical object comprising a plurality of 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;
- evaluating the captured image data or video data to obtain actual characteristics of the features, the actual characteristics of the features comprising spatial positioning information for the features on the physical object;
- decoding the captured image data or video data to obtain the expected characteristics of the features;
- based at least on the expected characteristics and the actual characteristics of the features, controlling display of user feedback on a display carried by a mobile device, the user feedback corresponding to an expected spatial positioning of the features relative to the physical object.
