The tag consists of micro- or nanoparticles randomly embedded into a thin layer of transparent polymer mass or randomly attached to various types of surfaces (metal, plastic, glass). As a result, the micro- and nanostructures, which exhibit bright luminescence in the visible range when excited by ultraviolet or contrasting light, create a unique pattern of bright points with random positions. Optical reading of this pattern using a smartphone and processing through application software will verify the authenticity of the tag. The physical non-clonability of the tag lies in the impossibility of replicating it, as its creation algorithm involves a series of non-deterministic, stochastic processes: as a result, each newly produced tag has a unique pattern of micro-particles and serves as a unique identifier for the specific product unit it is attached to.
CHARACTERISTICS
The algorithm for creating the security tag includes a non-deterministic process.
The security tag can be applied to solid (glass, metal) and flexible (plastic, textile) surfaces
The tag has an arbitrary shape, with an area of up to 9 cm² and a thickness ranging from 1 to 5 mm
The tag consists of micro-particles ranging from 30 to 500 micrometers in diameter, randomly mixed in a transparent protective shell made from epoxy resin derivatives with high adhesion to glass, plastic, metal, and paper
The security tag is resistant to water contact for up to 30 minutes, stable under sunlight exposure, and withstands temperatures from -20°C to 80°C
The tag is read in the optical range of 400-700 nm using a smartphone with a camera of at least 30 MP and digital zoom of no more than 5x through photographing (scanning), with authenticity verification conducted via developed software that processes the reading result and compares it with a database; the database size ranges from 1 GB to 4 TB
The software is written in Python, JavaScript/Kotlin and developed for Android / iOS smartphone operating systems
