Claim 16:
17. A method for authenticating an object, comprising:
projecting, via a first illumination source, at least one illumination pattern comprising a plurality of illumination features onto a surface of an object;
projecting, via a second illumination source, an illuminating light beam onto the object;
capturing, via at least one optical sensor having at least one light-sensitive area, at least one first image comprising a plurality of reflection features generated by the surface of the object in response to projecting the at least one illumination pattern onto the surface of the object and at least one second image comprising two dimensional information associated with the surface of the object in response to projecting the illuminating light beam;
evaluating, via an evaluation device in communication with the image capture device, the first image and the second image;
identifying, via the evaluation device, at least one geometrical feature of the object based on the reflection features in the first image;
determining, via the evaluation device, at least one material property of the object based on the reflection features;
comparing, via the evaluation device, the two dimension information of the second image to data stored in a database; and
authenticating the object based on the comparison.
