Description

The utility model relates to the garment industry, namely to a pocket device for improving information security.

A multi-section pocket is known (patent 195677, published on February 3, 2020, bull. No. 4), including three sections, two more sections are additionally made, while the first section is located between the garment and the main part of the folding pocket, made in the form of a longitudinally elongated rectangle, left part of which is fixed around the perimeter to the garment, leaving a horizontal entrance to the pocket from the top left, the second section is formed between the folding front side of the main part of the folding pocket and the inner side of the outer patch pocket part with a one-piece facing, with a transparent insert fixed in it, while forming the outer patch pocket with a vertical entry, the third section is formed between the right, folding inner part of the main part of the folding pocket and the inner sides of the upper and lower parts of the inner pocket, connected to each other by a one-piece zipper, thus forming an inner pocket with a vertical entrance, the fourth the first section is formed between the lower inner left part of the folding pocket and the detail of the mesh pocket, thus forming the inner mesh pocket with a vertical entrance, and the fifth section is formed by overlapping the left and right parts of the folding pocket connected to each other by means of the upper and lower zippers, parts of which are sewn along the right and left edges of a longitudinally elongated rectangle, with the beginning of the fastener from the vertical axis of symmetry, thus forming a folder pocket with a horizontal entrance.

There is a big problem - picking up acoustic information (conversations) using various devices. Moreover, such information can be removed secretly using, for example, a telephone belonging to a person. Often, for these purposes, various programs are secretly installed in this one, which produce such unauthorized recording (for example, such programs - https://4pda.ru/forum/index.php?showtopic=541212 https://bsr.ag38.ru/ ?lang=ru).

Various methods are used to counteract this negative impact - for example, the device is placed in a case or pocket shielded from electromagnetic waves (for example, the Hederson company produces jackets with such pockets - https://www.popmech.ru/gadgets/393982-seyf- v-karmane-kurtki-i-bumazhniki-henderson-s-zashchitoy-ot-vorovstva/).

The disadvantage of this method is that it does not protect, for example, from cases where the program records from the microphone at a certain time or constantly, and then saves or dumps it on certain servers (mail, cloud) when the Internet network appears.

A cover is known - an information exchange protection device when using a personal infocommunication device RU 185195 U1, 11/26/2018 (description p. 3 lines 2-4, p. 4 lines 3-42, p. 5 lines 13-30, p. 6 lines 12 -47, page 7 lines 4-8, formula, Fig. 1) is made in the form of a protective cover or case containing two parallel walls connected on three sides to form an internal pocket for placing an infocommunication device, the fourth side of the shell is made open to provide the possibility of convenient insertion or removal of the infocommunication device.

The disadvantage of this device is the inability to use it as a non-removable item of clothing.

A blocker for the operation of a mobile cell phone is known - the product "ASSISTANT" (www.aurix.ru/goods/goods9-7.html, 06/02/2020). As follows from the description of the product, the electronic unit for blocking the product "ASSISTENT" after switching on works almost continuously, blocking the operation of the microphone of the phone (several phones with their appropriate placement), if the microphone is near the acoustic noise emitter of the product. The electronic blocking unit of the "ASSISTENT" product consists of a radio receiver tuned to the frequency of the protected phone and an acoustic noise generator. All components of the electronic blocking assembly are located inside the cover (case, container) for storing a cell phone. In case of unauthorized turning on of the protected phone, the receiver of the "ASSISTENT" product registers the radio emission of the phone and turns on the noise blocker (acoustic noise generator), which completely makes the microphone of the protected cell phone noisy.

The disadvantages of the device include, in addition to the above, and the fact that there is a possibility of inoperability of the blocking device itself, for example, when its battery is discharged. The product has dimensions of 115-75-24 mm, and it must be worn simultaneously with a cell phone, which significantly increases the overall weight and size characteristics of the device. There is also an increase in acoustic interference in nearby third-party telephone communication channels.

In addition, there are a large number of hidden voice recorders camouflaged as ordinary household items (lipstick, pen - https://www.spycry.cora/promotest.html?step=6), which do not transmit "accumulated information" at all, and therefore, and the above methods against them will also be useless.

The closest analogue can be considered RU 185195 U1, 11/26/2018 Information exchange protection device when using personal infocommunication devices. According to this solution, the device is made in the form of a protective cover containing two parallel walls. The walls are connected from below and from the sides to form an internal pocket for placing an infocommunication device. The upper part of the shell is made open to enable insertion or removal of the infocommunication device and is provided with a flap valve. Each wall is made of four layers arranged from inside to outside: a layer of inner shielding material, a subsequent layer of shielding material, a layer of absorbing material and a layer of outer protective material. The layers of the shielding material and the absorbing material of each wall are interconnected by adhesive bonding, while at a distance of 2 mm of the outer edge, the layers are connected by stitching the layers around the perimeter with each other to ensure electrical contact between the layers. The disadvantages of the device include the inconvenience of using such a device. Thus, the user must either carry the device in a case in his hands, which is inconvenient, or the case must be placed in another product carried with him - for example, a bag (it is not a fact that the user will always have such a product (bag) with him). In addition, not all devices can be placed in such a case (dimensions may not match).

The technical result of the proposed utility model is to increase the efficiency of blocking a phone placed in a pocket from recording, possible removal of acoustic information, and transferring it to certain servers (mail, cloud) when the Internet appears.

The outer side (opposite to the body side) of the garment pocket is provided with a sound-absorbing material, and also the garment pocket is permanently secured to the garment. In this case, the pocket may contain at least one layer of material that shields from electromagnetic waves.

The outer side of the pocket can be made entirely of a sound-absorbing layer or contain a layer(s) of such material. It is possible to make the pocket entirely from such sound-absorbing material (both outer and inner side). This method (making the entire pocket of sound-absorbing material) will reduce the likelihood of picking up acoustic information, but will increase the cost of the entire product (the cost of a meter of such fabric can be up to 15-20 thousand rubles). Experiments have shown (experimental results see below) that even if only the outer side of the pocket is made using such a material (with NRC from 0.4 to 0.9), the recording of a quiet voice on a device (cellular) placed inside such an article (pocket) phone "Samsung") will be almost illegible.

This technical result is achieved by the fact that if the device with a microphone is placed in the claimed pocket when trying to record ambient acoustics, the intelligibility of such a record will be significantly reduced or completely absent due to the presence of a layer of sound-absorbing material.

In addition, ease of use will be expressed in contrast, for example, from a cover in that:

the pocket is designed to be permanently attached to the garment (thus, unlike, for example, a case, the user can store devices in such a pocket - the device is in a case, the user must either carry it in his hands, which is inconvenient, or the case must be placed in another portable product, for example, a bag (not the fact that the user will have such a product (bag) with him all the time).

Given that electronic devices can be quite significant in weight, the possibility of permanent fastening to a garment is carried out in any possible way (seams, gluing, etc.) that can withstand the weight of an electronic device of at least 500 grams (the weight of the heaviest tablets, smartphones https: //www.devicespecifications.com/ru/model/fb0c547d#:~:text=%D0%A2%D0%B5%D1%85%D0%BD%D0%B8%D1%87%D0%B5%D1% 81%D0%BA%D0%B8%D0%B5%20%D1%85%D0%B0%D1%80%D0%B0%D0%BA%D1%82%D0%B5%D1%80%D0% B8%D1%81%D1%82%D0%B8%D0%BA%D0%B8%20Apple%20iPad%20(2020).,(%D0%9B%D0%B8%D1%82%D0%B8% D0%B9%2D%D0%BF%D0%BE%D0%BB%D0%B8%D0%BC%DQ%B5%Dl%80%D0%BD%Dl%8B%D0%B9)%2C%20O %D0%BF%D0%B5%D1%80%D0%B0%D1%86%D0%B8%D0%BE%D0%BD%D0%BD%D0%B0%D1%8F%20%D1%81 %D0%B8%D1%81%D1%82%D0%B5%D0%BC%D0%B0%3A%20iPadOS%2014https://www.ixbt.com/news/2020/04/15/do-300 -grammov-stolko-vesjat-sovremennye-5gsmartfony.html#:~:text=%D0%9A%D0%B5%Dl%80%D0%B0%D0%BC%D0%B8%D1%87%D0%B5 %D1%81%D0%BA%D0%B0%D1%8F%20%D0%B2%D0%B5%D1%80%D1%81%D0%B8%D1%8F%20%D1%82%D1 %8F%D0%B6%D0%B5%D0%BB%D0%B5%D0%B5%2C%20%D0%B5%D0%B5%20%D0%BC%D0%B0%D1%81%D1 %81%D0%B0,%D0%BC%D0%B0%D1%81%D1%81%D0%B0%20%D0%BA%D0%BE%D1%2%D0%BE%D1%80% D0%BE%D0%B3%D0%BE%20%D1%81%D0%BE%D1%81%D1%82%D0%B0%D0%B2%D0%BB%D1%8F%D0%B5% D1%82%20300%20%D0%B3%D1%80%D0%B0%D0%BC%D0%BC%D0%BE%D0%B2).

The material of the outer wall of the pocket is also chosen in such a way as to withstand the maximum weight of the pocket of at least 500 g. At the same time, the pocket is made in such a way that the smartphone (as the most frequently used device from which leakage is possible) can be completely immersed in it (to avoid the possibility of leaks - confirmed experimentally).

Based on the size table of the most popular models, the dimensions of such a pocket should not be less than 1280 by 720 mm. (https://yandex.ru/images/search?pos=2&img_url=https%3A%2F%2Fwww.pvsm.ru%2Fimages%2FAndroid%27v-iz-kitava-kakie-oni-21.png&text=%D1% 80%D0%B0%D0%B7%D0%BC%D0%B5%D1%80%D1%8B%2Q%D1%81%D0%BC%D0%B0%D1%80%D1%82%D1% 84%D0%BE%D0%BD%D0%BE%D0%B2%20%D0%B2%20%D1%81%D0%B0%D0%BD%D1%82%D0%B8%D0%BC% D0%B5%D1%82%D1%80%D0%B0%D1%85%20%D1%82%D0%B0%D0%B1%D0%BB%D0%B8%D1%86%D0%B0&1r= 213&rpt=simage&source=wiz).

In the upper part of the pocket, for convenience (avoiding falling out), fixing the pocket (for example, with Velcro, lace, etc.) can be provided.

The author conducted a series of experiments. The Bauman acoustic cloth was used for the experiments (https://fabricmoscow.ru/catalog/akustika/). These fabrics pass the test of ISO/EN 354, ISO 11654 and DIN EN 29053 and are of unsurpassed quality in every sound range. Acoustic fabrics allow you to control and optimize the influence of extraneous noise, providing not only pleasant acoustics, but also attractive design solutions.

In this case, several types of fabric were used with a single NRC value from 0.4 to 0.9 (https://www.creationbaumann.com/en/Acoustic-fabrics-fbr-acoustics-and-aesthetics-in-harmony-18707.html ).

A single NRC value was calculated as the arithmetic mean of the sound absorption coefficient at acoustic frequencies of 250 Hz, 500 Hz, 1000 Hz, 2000 Hz (see https://stroy-master.com/consult/konsmat1.php).

This coefficient was chosen because it is calculated for sound absorption in the acoustic range from 250 to 2000 Hz, which approximately corresponds to human speech (which must be attenuated as much as possible to solve the technical problem).

For the experiment, we used a pocket sewn to a T-shirt (the material of the T-shirt is cotton). The pocket has been modified with a sound-absorbing element (according to the description and formula). The fabric used was different with an NRC coefficient from 0.4 to 0.9.

During the experiment, a Samsung Galaxy A12 device was placed in such a product (https: //www.citilink.ru/product/smartfon-samsung-galaxy-a12-sm-a 125f-sinii-1452260/?mrkt=msk_cl&utm_medium=cpc&utm_campaign= % 25D0% 25A1% 25D0% 25BC% 25D0% 25B0% 25D1% 2580% 25D1% 2582% 25D1% 2584% 25D0% 25BE% 25D0% 25BD% 25Dl% 258B & utm_source = xml_ymarket_msk & utm_content = 214_SAMSUNG_SM-A125FZBUSER & utm_term = 1452260 & ymclid = 16318527684755743711100002) and the taped acoustics. The source of acoustics is human speech at a distance of 0.5-0.8 m. The device was completely immersed in a pocket.

As a result of the experiment, it was found that even when using a material with an NRC of 0.4, significant results are noticeable. So, recorded by a device in a modified pocket with noise insulation, whispered and quiet speech was almost unintelligible. Whereas the same speech, recorded by a device in a pocket without noise insulation, was legible enough to understand the meaning of the transmitted information.

Thus, the experiment showed that the use of sound-absorbing material with NRC 0.4 already significantly reduces the likelihood of listening with the help of such devices placed in its inner space (pocket).

At the same time, it is known that there are numerous methods of covert access to confidential information using, in particular, mobile communication devices in case of unauthorized remote activation of the microphone (over the radio channel), as well as from leakage through the speech channel in case of unauthorized activation of the “voice recorder” function. For this purpose, special software can be used, secretly installed on a phone or smartphone (The secret way to listen to the surroundings using a smartphone. [Electronic resource]. URL: https://hi-tech.mail.ru/news/54039-sekretnyy- sposob-ustanovit-proslushku-s-pomoschyu-svoego-smartfona/; date of access: 21.07.2021).

To prevent the removal of any information from devices that have a radio channel (in addition to acoustic information, information about the location, etc., can be removed via the radio channel), in addition to sound-absorbing material, it is proposed to use one or more layers of material that blocks the passage of radio waves. Such material will block the passage of radio waves and, due to this, prevent the remote covert activation of microphones, cameras and other information transmitted over the air from mobile communication devices and other similar devices (where radio transmission is possible).

It is possible to use Aaronia-Shield fabric as such material.

This material has the following characteristics: Shielded frequency range 108 dB at 1 kHz, 100 dB at 1 MHz, 60 dB at 100 MHz, 44 dB at 1 GHz, 30 dB at 10 GHz.

99.9999% to 99.99999% static shielding efficiency (grounded only).

Against weak electric fields: 99.9999% to 99.99999% (grounded only).

Material Stainless steel.

Color Stainless steel.

Temperature limit 1200°C.

Obviously, the use of such a material will not give a 100% chance of blocking any radio signal in the range from 900 MHz to 3 GHz inside such products (all major digital standards work in this range - Wi-Fi, GSM, Bluetooth, etc.), but will significantly reduce the likelihood of removing such information (depending on the location of the radio signal transmitter).

The declared pocket can be placed in a bag or item of clothing.

In this case, the pocket can be made in any of the possible types, this is not the subject of the application.

For example, according to the processing method, there are four main types of pockets:

overhead (with an entrance from above and from the side), set-in slotted (with valves and one facing, with valves and two facings, in a frame, with a zipper, with leaves), non-cut, made from the main parts of the product (as a rule, they are located in seams, reliefs or folds: with flaps, without flaps, with leaves, with a zipper).
