Description

The utility model relates to the field of protection against access to the memory of unauthorized users, in particular, the destruction of data in the memory chips of portable storage media when there is a threat of their capture.

Destruction of information in memory chips of storage devices can be done using special programs that involve several cycles of rewriting data with a sequence of ones, zeros or random numbers. This requires a computer with appropriate software and a sufficiently long time to complete the task. In addition, there is a possibility of recovering destroyed data using special equipment.

It is possible to use special devices that affect memory chips with a powerful electric field. The disadvantage of such devices is the need for a sufficiently powerful power source to create a field, which is problematic in extreme conditions.

Guaranteed destruction of information is ensured by its destruction along with the media. In this case, the device can be destroyed by melting in a special furnace, using a micro-explosion, aggressive chemical components, etc. However, a micro-explosion and the use of aggressive chemical components may pose a certain danger to the user, and the oven will most likely not be used in an emergency.

In an extreme situation, the most preferable option is physical destruction of the data storage device or memory chip. A device for mechanical destruction of electronic storage media is known (US patent US 6189446, published 04/29/99). The device deforms the surface of the storage medium when passed between grooved rollers using a drive mechanism.

The disadvantage of this device is its structural separation from the storage medium, which requires a rather bulky design for use in extreme situations.

A portable information storage device with the possibility of its emergency destruction is known (utility model patent No. 208302, published 12/13/2021, Bulletin No. 35). The device ensures the destruction of the memory chip through the impact of a punch, held in its original state by restrictive brackets and a spring.

The disadvantage of this device is the impossibility of ensuring the tightness of the drive case, which can lead to dust and moisture penetrating inside and, as a result, its failure.

The closest technical solution to the claimed utility model is an information storage device with the possibility of its emergency destruction (utility model patent No. 150597, published 02/20/2015, Bulletin No. 5).

The device contains a housing on which a connector is installed, intended for electrical connections with a memory module located inside the housing. Such a connector can be, for example, a USB connector. A punch is placed above the memory module with the ability to perform rotational-translational movement in the housing and physically interact with the memory module, which is a memory chip installed on a printed circuit board in which there is a hole for the punch to exit.

The device ensures mechanical destruction of the memory chip, which guarantees the destruction of recorded information. At the same time, to destroy information, external devices and power sources built into the device are not required.

The disadvantage of the device is that the task of destroying the memory chip in an extreme situation depends on the state of the threaded connection and the hand strength of the user of the device. Contamination, misalignment and other factors can make it difficult for the punch to rotate and therefore move forward. The user's fingers may slip along the surface of the top of the punch and may not provide the required force to rotate it.

The purpose of the utility model is to increase the reliability of emergency destruction of stored information.

To achieve the purpose of the utility model in an information storage device with the possibility of its emergency destruction, containing a housing on which a connector is installed, designed for electrical connections with a memory module located inside the housing, above which a punch is placed with the ability to perform rotational-translational movement in the housing and interact with a memory module, which is a memory chip installed on a printed circuit board in which there is a hole for the punch to exit; on the side surface of the device there is a hole for installing a rod in it, limiting the movement of the punch relative to the body, additionally on the side of the upper part diametrically opposite to the place where the rod is secured The punch makes a slot with a width corresponding to the width of the rod. The rod itself is fixed on one side in the upper part of the punch on an axis, which allows it to turn into a horizontal plane and fit into the slot, extending 3-4 cm beyond the body to create a lever that increases torque.

New significant features: fastening the rod in the upper part of the punch on the axis of rotation and the presence of a slot in the upper part of the punch, which allows you to install the rod in it perpendicular to the axis of the punch to increase torque.

The proposed device differs from the known ones in design changes that provide increased reliability of destruction of the memory chip and, thereby, guaranteed emergency destruction of stored information.

Analysis of the level of technology did not reveal a means of the same purpose as the utility model, which has all the essential features given in the independent claim of the utility model formula, which indicates that the proposed technical solution meets the “novelty” criterion.

In fig. 1 - design of an information storage device with the possibility of its emergency destruction.

In fig. 2 - design of the device brought into position for emergency destruction of information.

On the housing 1 there is a connector 2 for electrical connections with the memory module 3, above which a punch 4 is placed with the possibility of performing a rotational-translational movement in the housing 1 through a threaded connection 5 and mechanical impact with its tip on the memory chip 6 installed on the printed circuit board 7, in which has a through hole 8 for the exit of the punch 4. The rod 9, which limits the movement of the punch 4 relative to the body 1, is fixed at one end in the upper part of the punch on an axis 10, which allows it to rotate 270° in a plane perpendicular to the axis of rotation of the punch, and the other end enters hole 11 in the body. On the side of the upper part of the punch diametrically opposite to the place where the rod is secured, a slot 12 wide is made, corresponding to the width of the rod, and with a depth that allows the rod to be completely “recessed” in the upper part of the punch.

The device works as follows.

In normal mode, through connector 7, information is written to and read from memory chip 6. The device provides data transfer from one computer to another. In an emergency situation, if it is necessary to urgently destroy information, the rod 9 is rotated to a position perpendicular to the axis of the punch and is recessed into the slot 12 in its upper part. The part of the rod protruding by 3-4 cm creates a lever that facilitates the rotation and, accordingly, the translational movement of the punch, which destroys the memory chip 6.
