Technologies of voice assistants or assistants are actively used in modern solutions. They are implemented on the basis of software that can perform tasks or provide services based on given voice commands by processing and interpreting human speech. Most communication tools are easy to use, but have typical and limited functionality for commercial use, in particular the implementation of security services. The paper proposes a model of a communication tool with a voice assistant and an increased level of security, which uses an advanced encryption method and a face recognition algorithm to provide security services. To build this model, the internal logic of performing functions and placing objects in systems with the functions of voice assistants or assistants was considered. The proposed solution uses a client-server architecture. As an additional direction of commercial use, the possibility of expanding the capabilities of the communication tool through the integration of auxiliary functionality in the form of a currency exchange module and decentralization of the system is being considered.
Modern information technologies provide
users with a wide range of services. Means of
communication are actively used for their stable
functioning. They can be in the form of a service,
application, etc. [
There is a significant number of similar tools on the market, some of them differ in their purpose, supported services and technological solutions. Developers of communication tools are trying to expand their capabilities in the direction of providing commercial services. However, existing implementations in this direction do not allow to meet the needs of users.
Users prefer means of communication with a
convenient, functional and understandable
interface, available visual effects, speed of
information exchange, reliability of stored
information, confidentiality, opportunities for
commercial use, etc. [
The relevance of the work lies in the high interest of users in the use of communication tools with a voice assistant, an inclusive interface, an increased level of security and opportunities for commercial use.
The novelty of the work is the improvement of existing approaches for recognizing named entities of the program text by taking into account contextual information, directions for increasing the level of security of the communication tool by improving the encryption method and the user's face recognition algorithm, as well as expanding the functional capabilities that are limited in most commercial products are proposed.
the Status of the Issue and the Statement of the Problem
Recent research in the fields of machine
learning and natural language processing has
made it possible to create impressive things that
seemed impossible before [
Voice control is an important emerging feature
that is changing the way people live. The voice
assistant is commonly used in smartphones and
laptops. AI-powered voice assistants are
operating systems that can recognize the human
voice and respond with integrated voices. In work
[
AI-powered voice assistants such as Alexa and
Siri are increasingly replacing search engines as
users actively use them to solve a variety of
everyday tasks. Technology providers, as well as
marketers, are increasingly working to attract
customers to use communication tools with voice
assistant functions. The work [
In [
In work [
Thanks to advances in voice recognition, users
can easily control any device in a smart home by
simply speaking a voice command. Based on this
idea, a new group of smart devices called voice
assistants has been developed and released.
However, voice itself is not secure and can be
attacked in many ways. To protect against voice
attacks, you can use the voice detection system
[
Currently, there are a significant number of means of communication, but not all of them are reliable and convenient. The proposed model of a means of communication with an increased level of security takes into account the shortcomings of existing solutions and provides an opportunity to realize the function of commercial use.
The proposed model of the means of
communication combines a number of solutions
that are not available from competitors, and this is
what guarantees commercial success [
A number of software communication tools
were able to gain success and take a confident
position in the market among users. Solutions
with a high level of success include the following
means of communication:
1. Viber: Viber Media company, Inc [
Exchange of messages; calls; creating your
own bots; convenient to use.
2. WhatsApp: Facebook company [
Exchange of messages, calls; convenient to use. 3. Messenger: Facebook company [16].
Exchange of messages; calls; convenient to use. 4. Telegram: Telegram FZ-LLC company [17].
Exchange of messages; calls; creating your own bots; convenient to use. 5. Instagram: Facebook company [18]. Exchange of messages; calls; display information about yourself, if the profile is not closed; information management; convenient to use. 2.4.
Many means of communication are easy to use. But most of them lack the ability to expand functionality. Not everyone can use their own means without the help of others. Thanks to such modifications as a voice assistant, an increased level of security, the presence of an inclusive interface and the provision of commercial services, the percentage of users of these tools may increase significantly.
The purpose of the research is to develop a model of an improved means of communication that provides an increased level of security and commercial opportunities. Consider the feasibility of integrating a voice assistant into similar tools inclusive. Currently, this technology is added to most commercial products. But this technology is absent in means of communication. Therefore, this modification is considered the newest among other software available on the market.
Adding to the means of communication the possibility of tracking the exchange rate and carrying out its exchange and transfer will expand the possibilities of using this tool. There are analogues of means of communication on the market with the possibility of exchanging one's own funds with other users, but the provision of material assistance is carried out by a minority. Not everyone has the opportunity to personally exchange / transfer their own funds to others. Therefore, a modification in the form of a voice assistant in the communication system will be useful.
The integration of the cryptographic data encryption module and the facial recognition function into the communication medium guarantees an increase in the level of security and reliability.
The set goal is achieved by solving the following tasks: 1. Conducting an analysis of the possibilities of the means of communication present on the market. 2. Development of a model of a means of communication. 3. Improvement of the method of encryption and face recognition. 4. Integration of the commercial capabilities module into a communication tool with support for voice assistant functions.
User interaction with the system is carried out using certain visual means. Thanks to these tools, you can work with the system and reveal its potential. Visual tools in such systems are called widgets [19].
In order for any user to be able to interact with the system, it is necessary to expand the functionality of the system: add authorization, registration, create a dialogue with other users, etc. All or most of these functions should be built into the voice assistant. In Fig. 1 is a use case diagram that demonstrates the main functionality of the system. 1. The original text, image or video is encrypted that automatically implements the performance of user functions. This feature will be added and will be available to all users of this system. 4.2.
To save data and maintain communication with other people through a means of communication, equipment is used, which makes it possible to store and display data in software (Fig. 2). Data is stored through a database [20].
Cryptographic encryption is the replacement of the data structure with symbols and the creation of a certain key to replace the symbols with the original structure [21]. Encryption is used for three purposes:
Thanks to cryptographic protection
methods, information can be made inaccessible to
persons trying to steal this information from the outside.
Immutability. Encrypted information cannot be tampered with during transmission or storage.
of the source.
Encrypted information has information about the sender.
Data transfer from one user to another occurs as follows: using an encryption algorithm, and the recipient has a special key to decrypt this data. 2. The encrypted message is sent to the recipient. 3. The recipient decrypts the message using a special key. 4.4.
In this work, the Pattern Reverse Subtraction (PRS) encryption method will be used. This method processes the input data by converting the binary value of the current symbol to decimal, where the key is then applied to form the encrypted data.
Encryption will occur as follows: 1. Creating a key. 2. Creating a reverse key. 3. Receiving bytes from input data. 4. Subtraction of the current byte until the condition 0 ≤ L is met, where L is the length of the key. 5. This number is taken as an index from the reverse. The output number is taken as the index of the value from the key reversal. 6. Adding a number after each operation on the byte, which will reflect the number of differences before obtaining a valid value. Decryption uses the following formula: =1 ∑ + , (1) where n is the number saved in the encrypted file;
Compression. To achieve a lower amount of equipment physical memory costs, the following approach to data storage will be used (Fig. 3) [22].
Data compression is divided into two types: 1. With losses. 2. Without losses.
With losses. Removing unnecessary bits of data where after decompressing the compressed file you can get the raw data.
Without losses. Compression of information without replacing the symbols of the input data, where after decompression the output data will be obtained.
When studying this encryption method, it was decided to use a type of losses compression for a large amount of data. The study showed that the use of this type of compression did not lead to the detection of errors and incorrectness of the original data.
One of the methods of maintaining confidentiality and preserving the reliability of the program is authentication using characteristic points on the face-face recognition (Fig. 4).
Face recognition is a means of recognizing characteristic points of a person’s face and its verification. Characteristic points are determined on the face, and make it possible to recognize the corresponding person [23].
This technology is needed to increase the level of data security of registered users. 4.6.
Functional completeness is performing the
main functions of effective management and
providing a convenient interface for the user [
The functional completeness is as follows: 1. Authorization. Inclusive authorization. 2. Registration. Inclusive registration. 3. Creating a chat for interviews with the possibility of using a voice assistant. 4. Creation of group chats for interviews with the possibility of using a voice assistant. 5. Exchange of messages with the possibility of using a voice assistant. 6. Sending photos and videos. 7. Viewing videos and photos using a voice assistant. 8. Sending voice messages. 9. Converting voice messages into text. 10.Changing profile settings.
Portability is a property that indicates how
easy it is to transfer / install the system to a certain
device. Currently, software development tools
have the ability to create an executable program
for various operating and mobile systems [
Reliability and fault tolerance. For example,
the system will have a number of functional
capabilities, where in the future it will be possible
to make corrections in the processing of data and
clients, so reliability and fault tolerance are at a
sufficient level [
Security. In any case, the data will be
transferred over the network between the server
devices. Therefore, the proposed PRS data
encryption method with E2E (end-to-end) data
transmission is used [
For authorization in the system, it will be possible to create additional authentication— facial recognition.
Extensions is the possibility of adding/modifying the software product. The following diagram (Fig. 5) shows the structure of the future software product.
Productivity. Thanks to well-written software,
you can achieve a high level of productivity. To
achieve high performance, you need to have
equipment that will ensure fast processing of input
and output data, in particular voice requests from
users [
of Communication by Adding
The expansion of the audience of users is
planned due to the addition of opportunities for
conducting financial transactions. This extension
will make the software product more successful.
Due to the minimal increase in the commission for
the transfer of currencies, there will be an
increased profit for the corresponding period of
time. Finance departments are interested in
cooperating with such tools, because their number
of users will be able to expand and increase the
level of profit. Cooperation will take place
through the API (Application Programming
Interface) of financial departments for the
interaction of their services with their own
developed software and system users [
An account will be created for the financial support of the relevant users, where funds will be received for the percentage of the transfer of funds from other users and sent to the relevant rehabilitation institutions. 5.2.
Decentralization is the process of distributing
people, rules, performing calculations, data stored
from a single location or central governing body
[
When applying the blockchain technology, it
is necessary to define and distribute rules between
users and computing devices, achieving
consensus, in particular, connecting other users
who must verify the authenticity of data due to
stored copies [
This improvement will be useful for people
who do not want to lose their personal information
and use the application without entering
information about themselves [
The implementation of points 5.1 and 5.2 will make it possible to raise the level of commercial attractiveness of the improved means of communication. Currency exchange in a closed system can be interesting for a large number of users.
The following formula can be used to obtain the probability of success of improving the means of communication: = × × , (2) where C is the probability that the changes will be successful; А is dissatisfaction with the existing situation; В is a clear formulation of the goal of the changes; D is specific first steps to achieve goals.
The paper examines the functioning scheme of means of communication called “messengers.” To build a model of an improved means of communication with a voice assistant, the internal logic of performing functions and placing objects in similar means was considered. The work proposed improved principles of increasing the level of security of products of this type by improving the encryption method and the face recognition algorithm, as well as expanding the functionality that is missing in most commercial products. The tool is built using a client-server architecture. This security model and method provide an opportunity to protect data at a sufficient level. To provide convenience to users, a decision was considered to add a voice assistant to the system. This modification will be useful for all users of the system. The work proposed the possibility of expanding the system with the help of auxiliary functionality in the form of a currency exchange module, which is intended for a certain category of users interested in this system.
The system is built on the basis of a micro service approach, which ensures scalability and low resource consumption when adding new functionality or replacing existing implementations. The created voice assistant for integrated development environments allows to increase the productivity of developers, and also provides an opportunity to support the standards of conventions of inclusive interfaces.
Based on the results of the research, the logic of the communication tools was determined. Thanks to this, you can design a software product that will be different from similar products on the market.
So, as the system operation scheme was considered in detail, these systems can be expanded not only externally, but also internally. Several examples have been given of how the functionality of the product can be extended.
