As reported “MK” the scientist Andrei Nikolaev, the idea to create such database “passports” came to him when he began to closely study how in Russia there is a wood. It turned out that the paper on felling and transportation of wood can be used for several years, it is difficult to calculate where deforestation has occurred in the right or wrong place.

The basis for his new method of Nikolaev took the uniqueness of the images of tree rings, each of which is unique, like fingerprints in humans. The scientist offers to take photos cut down a tree (a suitable cut one branch) and put them in a common database, where each sample will indicate the area where it grows. And in order to detect poachers, would be enough to take a picture of the transported slices of the wood when testing, place the image in a program to search for matches among the photo collection database. And thus to know to which place it had been cut. In addition, Nikolaev offers by the carriers of wood to photograph the sections (it is possible to draw General picture of the saw cut) and place on the base site as a further proof of his honesty.
