A system includes a memory, a processor in communication with the memory, a unique identifier generator, a transmitter, at least one receiver, a display, and a viewing aid. The transmitter is configured to transmit information about a unique identifier generated from the unique identifier generator. The receiver is configured to receive the information from the transmitter. The display is configured to emit polarized light at a plurality of polarizations. Additionally, the plurality of polarizations includes a plurality of different noise polarizations and polarized light at a polarization factor based on the unique identifier. The viewing aid has a filter that is configured to pass light at the polarization factor and block light at the plurality of different noise polarizations.
