Claim 0:
1. An authentication system, comprising:
a lighting device configured to emit light through a physical authentication device (PAD);
a light sensor configured to sense the light emitted through the PAD;
a user interface;
a processor; and
a non-transitory memory having stored thereon instruction executable by the processor to cause the authentication system to perform operations comprising:
receiving a code via the user interface;
emitting light of a color that is associated with the received code via the lighting device and through a specific PAD corresponding to a particular user, wherein the specific PAD includes particular physical distortions differentiating the specific PAD from other PADs that are configured for use with the authentication system, the other PADs corresponding to other users;
detecting, at the light sensor, light data for the emitted light, where the light data includes distortion data caused by the emitted light passing through the particular physical distortions differentiating the specific PAD from the other PADs;
performing an analysis of the light data including the distortion data; and
based on a result of the analysis of the light data including the distortion data, determining whether the particular user is authorized to perform an action.
