Description

The invention relates to the field of storage and protection of information from unauthorized access, in particular to devices for the emergency destruction of electronic media by means of their physical destruction at the user's command.

Currently, storage devices are used everywhere. Along with public information, there is confidential information that requires special protection and, if necessary, immediate destruction. There are two ways to destroy information from a media: by means of software for erasing information and by disabling the media itself due to physical impact on it.

There are known methods for erasing information from computer memory using software erasure [1], but their disadvantage is low reliability, since it requires a large number of operations and leaves the possibility of information recovery (the memory chip is not physically destroyed).

A device for destroying information [2] is known, placed on a solid-state digital drive SSD (solid-state drive), where a mechanical method of destroying information is used by moving a shock plate with shock elements. The drive is clamped with brackets, and with the help of electrodynamic repulsive forces that arise between the coil and armatures, shock plates move, which penetrate into the storage medium and destroy the information on it. The disadvantage of this device is the relatively large size, which makes it difficult to use, as well as a large number of preparatory operations.

Known means of emergency destruction of storage media using high temperature [3], created by a cumulative jet in a closed volume. The method is carried out by melting the information carrier under the influence of a cumulative jet, followed by sintering under the action of a temperature released during the combustion of plates from a pyrotechnic composition.

The disadvantage of such a device is the low user safety due to strong heating and possible deformation of the device, large dimensions, as well as the fact that the tool itself is not an information carrier, which makes it difficult to quickly and autonomously destroy data.

The closest to the proposed solution in terms of technical essence and the achieved result is a device for destroying a memory chip crystal [4], which is a sealed housing in which a working charge is installed, an element for engaging the working charge and an initiating element containing current-carrying electrodes with a burnable incandescent bridge, and the working the charge and the activation element are made of pyrotechnic compositions, while the activation element is installed between the information carrier and the working charge.

The disadvantages of the device, adopted as a prototype, are the high complexity and time of putting it into action, the narrow focus of use (as part of an electronic unit), i.e. the device is an integral part of a larger object and cannot function autonomously as a standalone device.

The aim of the invention is to create a small-sized autonomous storage device for information on an integrated memory chip with the possibility of its reliable and trouble-free destruction at the user's command without the possibility of recovery if there is a danger of its leakage.

The device contains an integrated microcircuit of the USB-drive memory and is an information carrier that does not require additional actions to be installed in the destruction device, which allows the destruction to be completed in the shortest possible time, which makes it autonomous and convenient to use.

This goal is achieved by the fact that a small-sized electric detonator is used as a charge in a sealed case, the destructive effect of which is to combine the method of throwing its metal cup with the impact of a shock wave, installed in close proximity to the memory integrated circuit.

An information storage device with the possibility of its destruction (Fig. 1) consists of a sealed device case 1, an electric detonator (hereinafter referred to as ED) 2 with a metal throwable cup 3, a plastic frame 4, an integrated microcircuit of the memory of a USB drive 5, a fiberglass printed circuit board 6, a built-in power source 7, activation key ED 8, USB connector 9, cap 10, housing of the activation mechanism for the destruction of the memory integrated circuit 11, spring-loaded rod 12, conductive head 13, guide 14, spring 15, button 16, cover 17.

The hermetic case of the device 1 is a hollow elongated metal body of a cylindrical or cubic shape with wall thicknesses that provide reliable protection of surrounding objects from damage as a result of actuation of the EM 2. A plastic frame 4 with grooves is installed inside the case, which performs the function of fixing the USB memory integrated circuit at a given distance - drive 5 from fiberglass printed circuit board 6.

On one side of the plastic frame 4, a fiberglass printed circuit board 6 is attached with a built-in power source 7 installed on it, an activation key ED 8 and metalized pins on which the ED 2 is put on. On the other side of the plastic frame 4, an integrated microcircuit of the memory of the USB drive 5 is installed.

On the fiberglass printed circuit board 6 there is a metallized pattern that connects in series the built-in power source 7 installed on it, the activation key ED 8 and ED 2.

On one of the side bases of the case there is a slot for the output of the USB connector 9, which is closed with a cap 10 to protect the USB connector 9 from various external factors, such as high humidity, dust, etc. On the second side base of the sealed device case 1 a mechanism for activating the destruction of the memory integrated circuit is installed, which also performs the function of sealing the internal parts of the device.

The activation mechanism for the destruction of the memory integrated circuit is a housing for the activation mechanism for the destruction of the memory integrated circuit 11 with a through hole in which a spring-loaded rod 12 with a conductive head 13 is installed. in a predetermined position, as well as performing the function of a stop for the spring 15. On the outer side of the body of the activation mechanism for the destruction of the memory integrated circuit 11, there is a button 16 made of a sealing gasket in the form of a "hat". In order to protect the button 16 from accidental pressing, a cover 17 is attached to the body of the mechanism for activating the destruction of the memory integrated circuit 11, which has a warning marking applied to its surface.

The principle of operation of the device

If it becomes necessary to destroy the information, the user presses the button 16, as a result of which the spring-loaded rod 12 moves, and the conductive head 13 closes the activation key ED 8. The built-in power source 7 heats the incandescent bridge located in the ED 2, which ignites the initiating explosive (IVV ). IVV activates a high explosive (HBB), which, when detonating, throws a metal throwable cup 3 towards the memory chip of the USB drive 5 and creates a shock wave that destroys the memory chip of the USB drive 5. At the same time, the integrity of the hermetic case of the device 1 is not violated, thereby ensuring the safety of the user of the device.

If it is necessary to destroy the integrated memory chip of the USB drive 5 during use in a computer, when a command is given to close the activation key ED 8, only the integrated memory chip of the USB drive 5 is physically destroyed without causing damage to the workplace (computer).
