Synthetic prints will form the basis of future security systems
A group of researchers from the University of Kyung-Hee in South Korea, led by Wook Park, developed a technology that could be the basis for future security systems. They invented patterns that were randomly generated and resembled fingerprints. The prints are unique and cannot be recreated, which is the key to security. Wook Park is confident that their development will be put to practical use in the future.
To obtain such imprints, the South Korean researchers cover the plastic particles with a thin layer of silica, and then soak them in ethanol and allow them to dry out. As a result, silicon dioxide is formed, which just creates unique patterns. It is interesting that, despite the accidental formation of such a print, specialists have learned to control this process in order to determine in which place the convexities should appear. To do this, they use ultraviolet emitters. In places where the beam touches the pattern, it breaks, bends or breaks.
Researchers argue that the ability to manage this process can be extremely useful for protecting the transmission of messages. Exposing a group of particles to the same light exposure, you will create an installed set with similar points. Each final print will be unique, but the set of locations of such points can be used to determine whether it belongs to a particular group.
Now scientists are busy developing a compact scanner to read the prints they created. Time will show whether this technology will gain wide application.
