1. A method, comprising:
receiving, at a processor, a signal representing an image of a serialization code and an identifier of a label including a set of flecks having a random distribution;
detecting, via the processor, the serialization code;
identifying, via the processor and within the image, the set of flecks;
identifying, via the processor, metrics associated with each fleck from the set of flecks;
comparing, via the processor, the identified metrics with metrics associated with a unique signature; and
causing display, via a user interface, of a message indicating an authenticity of the label based on the comparison.
