Description

The claimed solution relates to the field of technology - mobile communications, and more specifically to the hardware and software of radio communications used in conjunction with mobile (cellular) phones (headset), while ensuring the protection of information, both received and sent using the phone.

Nokia WH-500 stereo headset (accessories / headsets / wired-headsets / wh-500) is known from the prior art. It consists of two speakers, a microphone, a button for answering an incoming call, connected to each other and with a cell phone by cord connection.

A disadvantage of the known device is the inconvenience of wearing and operational use of the telephone headset. A wired connection to a cell phone limits the amount of storage space for the cell phone in standby mode due to the limited cord length and the need to constantly connect the headset to the phone you are using. As a result of this, this headset is used mainly for listening to music, with the ability to answer in the event of a call to a cell phone.

A headset is known from the prior art consisting of an input plug, a two-wire cable, the upper part of which is branched and equipped with headphones at its ends, characterized in that the surface of the insulation coating in the wire headset from the input plug to the branch of the main part of the headset cable the main part of the wire cable is made in such a way that exciting components are created from a pair of snake-clasps that make up the insulation of the main part of the wire cable, it’s a whole, and these gripping components are made so that they perceive each wire of the branched part of the wire cable as an interacting, complementary element of each gripping component of this pair of snake fasteners (RU No. 2433565, IPC Η04R 1/00, 11/10/2011 )

A device is also known from the prior art - a headset for a cell phone, characterized in that it consists of two parts, one of which is attached to the wrist mainly in the form of a bracelet, and the second - on the finger of the same hand, made in the form of a ring connected to the cell the phone through Bluetooth wireless technology, the first part is equipped with a microphone, and the second part, made in the form of a ring, has a speaker (RU 95201, Η04В 1/38, 06/10/2010).

Also known is a headset for mobile communication devices and Internet telephony (hereinafter - UMSIT), which is an auxiliary electronic device whose speaker is attached to the headset user’s ear or inserted into the UMSIT user’s ear, which interacts with UMSIT wirelessly by radio or wire, characterized in that the headset is in operable condition both when it is connected firmly to the UMCIT and when the headset is disconnected from the UMCIT (RU 2009133019, Η04Μ 1/725, 02.20.2010).

At the same time, a telephone-microphone headset (TMG) is known that contains headphones with telephones, a laryngophone type microphone and connecting cables with a connector for connecting to a portable radio station, mobile radiotelephone or other transceiver system, characterized in that, in order to increase the reliability of communication, ergonomic qualities and secrecy of the operator’s work, the design is waterproof, headphones with phones are placed in the pockets of the headband, and two microphones are located in the temporal areas of the head The operator’s output, the output of each microphone is connected to the input of the microphone amplifier built into its body, and the output of each microphone amplifier through the connecting wire is connected to the input of the compensation amplifier built into the body of each headphone, the outputs of both compensation amplifiers are connected in parallel, like the inputs of the headphones, and connected via a connecting cable with a connector to a portable radio station, mobile phone or other transceiver system (RU 99105692, Η04Μ 1/05, 08.27.2001) (the closest analogue).

A common drawback of these devices is the lack of the ability to protect information received and sent using a mobile (cellular) telephone when using its (telephone) headset.

The objective of this solution is to eliminate the above drawback.

The technical result is to increase the level of security of the process of receiving and transmitting information using a mobile device.

This problem is solved by creating a headset for mobile devices with a communication encryption function containing a telephone connection module, microphone, speaker, and autonomous power supply elements made in a single housing. The headset is also equipped with an encoder and microcontroller, providing encryption and decryption of information transmitted through open channels.

Additionally, the headset may contain a microphone amplifier, as well as a volume control.

Using various encryption tools, with a given long key, the headset skips the received information, and then encrypts it on the encoder (information encryption block).

Thus, through the encoder, the headset performs the functions of encrypting the outgoing and decrypting the incoming call.

In general, the device is a headset with a built-in encryption algorithm to provide secure communication. The solution is a complex of a headset hardware device, and a software application for the operating system.

Below is a description of the graphic materials explaining the essence of the solution.

In FIG. 1 is a functional diagram of a device. It is important to note that the subscriber’s phone does not have access to the original open information and acts only as a transmitter of encrypted data. This implementation of the call system involves the transfer of data via any communication channel available to the subscriber with the Internet: GPRS, EDGE, 3G, Wi-Fi.

In FIG. 2 is a diagram of the interaction of subscribers with the server.

Figure 3 - appearance of the headset "Tectus".

The claimed utility model contains, shown in FIG. 1, a speaker / microphone (audio in / out) of a data source / reader operating in full duplex mode. From source / reader data

come to the audio codec which performs the function of an ADC / DAC (electronic device that converts voltage to binary digital code). DSP acts as a microcontroller, encoding and decoding a digital code. DSP is connected to mini usb to exchange contacts and charge the device. DSP is connected to the LCD and Joystick, which in turn are display and with control buttons that are responsible for receiving a call, volume control. Data transfer between a communication cryptographic device and a telephone / other mobile device via a bluetooth module.

The claimed device operates as follows.

A call to the subscriber is initiated by the application for the operating system. The headset, through the encoder, processes the input audio stream coming from the microphone, encodes and encrypts it, then sends encrypted data, for example, via Bluetooth to the phone, which, in turn, transmits data through the server.

After receiving data from the server, the application sends them to the headset also via Bluetooth. The headset receives data, decrypts it using an encoder and reproduces sound in the output audio stream.

At the same time, a communication cryptographic device (headset) establishes a gateway between two subscribers.

The data transfer between the multifunction interface and the source / reader is encrypted. Since it passes through the encryption block (encoder).

The operation of transferring data between two devices is as follows.

The subscriber transmits his voice message through a microphone to the data source / reader unit, passing through the encoder, then the encrypted information goes to the transmission unit and communicates with the phone or other mobile device that is connected to the phone / mobile device of the second subscriber, which in turn is connected to a second utility model of a communication cryptographic device. Inside the second communication cryptographic device, the received information is decrypted on the encoder, after which the decrypted information goes to the speaker.

Data transfer between a communication cryptographic device and a telephone / other mobile device via a Bluetooth module.

It is allowed to use a multifunctional interface connected to the display and control buttons responsible for receiving a call, volume control.

The headset provides hearing protection from extraneous noise, allows you to perceive information and at the same time makes it possible to quickly exchange information with the interlocutor.

When implementing the solution, an increase in the level of security of the process of receiving and transmitting information using a mobile device is achieved.
