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 microcircuits of portable storage media with the threat of their capture.

The destruction of information in memory chips of storage devices can be done using special programs that involve several cycles of data rewriting with a sequence of ones, zeros or random numbers. This requires a computer with appropriate software and a sufficiently long task execution time. In an emergency, as a rule, there is neither one nor the other. In addition, there is a possibility of recovering the destroyed data using special equipment.

It is possible to use special devices that affect the 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.

Guaranteed destruction of information is ensured by its destruction together with the carrier. In this case, the device can be destroyed by melting in a special furnace, using a microexplosion, aggressive chemical components, etc. However, microexplosion can pose a certain danger to the user, and the use of the oven in an emergency is problematic due to the bulkiness of the equipment, the required power supply and the long time to complete the task.

In an extreme situation, physical destruction of the data storage device or memory chip seems to be preferable. A device for mechanical destruction of electronic storage media is known (US patent US 6189446, published on April 29, 1999). The device deforms the surface of the information carrier when passing between the notched rollers using the drive mechanism.

The disadvantage of this device is its constructive separation from the information carrier, which requires a rather cumbersome structure for use in an extreme situation.

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, publ. 20.02.2015, bull. 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. Above the memory module, there is a punch with the ability to rotate and translate in the housing and interact with the memory module, which is a memory microcircuit installed on a printed circuit board, in which a hole is made for the punch exit.

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

The disadvantage of the device is the dependence of the performance of the task of destroying the memory microcircuit in an extreme situation on the state of the threaded connection. Contamination, misalignment, and other factors can stall rotation and therefore translational movement of the punch. The person may not have enough finger strength to scroll.

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

To achieve the goal 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, for example, a USB connector intended for electrical connections with a memory module located inside the housing, above which a punch is placed with the possibility of rotational-translational movement in the housing and interaction with the memory module, which is a memory microcircuit mounted on a printed circuit board, in which a hole for the punch exit is made, instead of the threaded connection of the body and the punch, a spring and two limiting brackets are installed between them.

New essential features: the presence of a spring between the body and the punch, the presence of two limiting brackets to prevent accidental activation of the percussion mechanism, the absence of a threaded connection.

The proposed device differs from the known design changes, providing an increase in the reliability of destruction of the memory microcircuit and, thereby, guaranteed emergency destruction of stored information.

The analysis of the state of the art 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, which indicates that the proposed technical solution meets the "novelty" criterion.

FIG. 1 shows the design of a portable data storage device with the possibility of its emergency destruction:

1 - case, 2 - memory microcircuit, 3 - printed circuit board with a hole for the memory microcircuit, 4 - punch, 5 - spring, 6 - restraining brackets, 7 - USB connector.

In the housing 1 there is a memory microcircuit 2, installed on a printed circuit board 3, in which a through hole is made for the output of the punch 4. The punch is directed with a point on the memory microcircuit and in the initial position is held by two limiting brackets 5, and a spring 6. Electrical connection of the memory microcircuit with the means computing technology is provided by USB-connector 7.

The device works as follows. In normal mode, information is written into and read from memory microcircuit 2 through the universal USB connector 7. The device provides data transfer from one computer equipment to another. In an emergency, if it is necessary to urgently destroy information, the restrictive brackets 5 are removed and a blow is made on the punch 4 with a hand or some object. Spring 6 will be compressed, and the punch will forcefully hit the memory chip, destroying it. Due to the placement of the hole in the printed circuit board under the microcircuit, less effort is required to move the punch, the microcircuit is destroyed into more fragments, which has a positive effect on the quality of destruction.

After the impact has ceased due to the action of the spring, the punch will return to its original position. It can be hit several more times, which is guaranteed to destroy the microcircuit and destroy the stored data.

In a threatened period, to reduce the time required to complete the task, the restraining brackets can be previously removed, while the punch will be held in its original state by the force of the spring.
