The invention relates to the information security engineering, more specifically to the security of information on the digital information tanks in case of its leakage risk. An electromechanical device for protecting information on a digital carrier against unauthorized access is composed of an inductor 1 connected to a charged capacitor storage and of a movable armature conductive disc 3, impact disc 5 and striker 6, those are installed coaxially. The inductor 1 and armature conductive disc 3 are installed inside coaxial ferrite core made in the form of a cup 7 covered with a cover the cover 8 of the core a number of axial guide holes 9 is made, inside which arranged are the guide rods 10 connected by one end 10a to the impact disc 5, and by the other end 10b – to flat bosses 11 interacting with the armature conductive disc 3. The pointed part 6b of the striker 6 is directed to the information digital tank 14. The digital tank 14 is fixed relative to inductor 1 by means of the lateral supports each of which is made in the form of two parts 16 and 17 turned to each other and made with teeth 18 and 19, being in engagement and inclined, this enables only mutual approach of digital tank 14 and inductor 1 prior to interaction of impact disc 5 with a rear side 6a of the striker 6 under action of tightening spring 20 connecting the parts 16 and 17 of a lateral support. The technical result consists in strengthening of magnetic fields in active zone between the inductor and the armature conductive disc, improvement of conditions for penetration of the striker to digital information tank at each following power pulse, due to this the efficiency of the device for protecting information increases with simultaneous reduction of its size, and reduction of external magnetic leakage fields. |
