Abstract
System and method for optically verified sample authentication are described herein. An example system includes a detection device to authenticate a sample and to return a positive authentication result if the sample is authentic and return a negative authentication result if the sample is not authentic, the detection device containing an optical emitter to emit a series of pulses of light in a first sequential pattern, a smartphone in close proximity to and facing the detection device and the sample, the smartphone containing a camera to detect the first sequential pattern of light, and a database to store data from the smartphone, wherein the optical emitter emits the first sequential pattern of light before the detection device authenticates the sample, the smartphone captures a first image of the detection device after the smartphone detects the first sequential pattern of light emitted by the optical emitter, and the smartphone transmits first data to the database after the detection device authenticates the sample.
