Quantum effects in information technologies of identification and authentication

A new photochemical technology for the formation of hidden markers — protective identifiers for various polymer products and other materials — has been developed. This technology allows you to code the identifiers of both individual products and batches of products of various types. Developed markers can be nanostructured and do not disrupt the appearance of products. The possibility of formation in various materials of hidden stable identifiers, which can be performed with a thin periodic structure, including on the basis of nanotechnology, is shown. The use of such markers implements the possibility of developing new design elements for products with multi-level encoding. The proposed technology combined with the development of methods for reading hidden and multilevel information can serve as a basis for the development of a new method of identification and protection against falsification of products, documents, media, valuable items.
