FIELD: information technologies.
SUBSTANCE: between capacitor coatings n plane inductance coils differing by thickness, wire length, number of turns, areas, direction of winding which are connected in series, in parallel or in mix are placed, and capacitors have different values of dielectric permeability and are connected to AC stabilised power source.
EFFECT: electronic key at the output generates its unique time chart, by similarity of a fingerprint of the person which is compared to the chart contained in the file with the protected information and at their coincidence the access, for example to personal information of a citizen, is permitted.
