Description

The invention relates to methods of registering the reception of money, values or marks, including the work of cash registers with the function of transmitting information to the tax authorities through the operator of fiscal data in the absence of a stable Internet communication channel in the cash register equipment.

In the prior art a method of controlling the revenue of electronic cash registers is known, based on recording information and its accumulation by means of a fiscal memory block with the exception of the possibility of changing it, transmitting information via a communication channel to a non-volatile portable storage device (see RU 2106015 C1).

This method does not provide continuous transfer of data on revenues to a non-volatile portable storage device and, all the more, the problem of transferring data on revenues during disconnection and restoration of communication is not solved.

The closest to the claimed invention is a method of operation of the cash register with the function of transmitting information to the server of the fiscal data operator and the server of the fiscal data operator when disconnecting and restoring communication (see RU 2563246 C1).

In this method, information is generated from data on cash payments and / or payments using payment cards and the number of each cash voucher and storing information in the memory of the cash register. When communication is restored via communication channels, the cash register sends sequentially to the server of the fiscal data operator data on cash payments, the number of each check and the identifier of the cash register. The server checks the identifier of the cash register with the subsequent decision to allow or deny access to the server. When allowing access to the server, it generates a unique code for each check by the server and saves the data on cash payments, the identifier of the cash register and the unique check code for each check in the operational database. After that, it transfers the unique code of each check from the server via communication channels to the cash register. When the connection is disconnected, they can beep and / or print text on the cash register screen.

According to the current legislation, the owner of cash registers (cash register or machine) is obliged to transfer information about cash settlements to the tax authorities at the time of settlement. Traditionally, the moment of settlement refers to a time of no more than 5 minutes from the transaction. However, the method described above does not reflect the exchange of data between the operator of fiscal data and the tax authority, and does not guarantee that the information transmitted by the cash register will be transferred to the tax authority without distortion and within the statutory period. That is, the owner of the cash register is not informed that the information from his cash register has reached the tax authority. The lack of timely data transfer to the tax authority threatens the user of cash registers with a fine. In addition, the server of the operator of fiscal data is forced to check all the identifiers coming to it, together with fiscal data, the size of which can reach tens of kilobytes, which dramatically reduces the server's performance. Mandatory verification by the operator of the entire amount of fiscal data coming from the cash register information technology can lead to a situation that can be exploited by attackers when creating a computer program aimed at continuously sending false information to the operator of fiscal data that is structurally similar to fiscal data, that is, organized DDoS-attack server operator fiscal data. Failure on the server side to filter on incoming false information can lead to the loss of the server's ability to quickly process information, which will cause the server to freeze. Thus, it turns out that with today's data transfer method on the server there is no protection against DDoS attacks. Some servers of operators of fiscal data for protection against DDoS-attacks set the intervals between calls from cash registers and periodically break the connection with cash registers. But in this case, users of cash registers will suffer, who have had interruptions in the work of the Internet, and who have accumulated a large number of checks to send, and according to today's requirements, the accumulated checks must be unloaded without breaking the connection continuously.

In addition, by giving only a sound signal and / or printing text on the screen of cash registers, it is not possible in all cases to convey information to the owner of the cash register, as the cashier-operator can be another person, not the owner himself, the sound signal conditions of the store may not be heard by the operator working on CCT, as well as service information that appears briefly on the screen may not be noticed by the cashier when working with cash registers.

Thus, the known level of technology, including the closest analogue, contains a sufficient number of the disadvantages listed above.

The objective of the claimed technical solution is to eliminate the disadvantages of the prior art.

The technical result, the achievement of which the claimed invention is directed, consists in more complete control by the user (owner) of the cash register equipment for passing information from the cash register equipment to the tax authorities through the fiscal data operator and back to the cash register equipment unstable internet communication. This result is achieved by informing the user of the cash register when printing periodically on the printer (after 5 minutes every 60 seconds), by issuing a sound signal with a programmed frequency (after 5 minutes every 60 seconds), continuously displayed on the screen the number of unsent checks. and the time of the last non-transmitted check (if any), obligatory sending the user a notification by e-mail and (or) via instant messengers (Viber, WhatsApp, Telegram, LINE and others) info Information about the number of unsent checks and the last time of the unsent. In addition, on the side of the fiscal data operator, preliminary registration of user data is entered through the user's personal account. The following information is entered in the user's personal account: taxpayer identification number (TIN), factory number of the cash register, registration number of the cash register, the address of the installation site, etc. After the user’s registration in the personal account of the fiscal data operator, these parameters are entered to the cash register equipment and a special registration report is generated, which is also accompanied by a special identifier confirming the correctness of the entered data, and sent to the fiscal data operator. After checking the registration data entered through the personal account with the data sent by the cash register in the registration report, the fiscal data operator receives the messages and further processing, but already with the user registered with the fiscal operator of the particular cash register. Verification of registration data, in contrast to verification of an identifier, takes much less time, does not load the server and can significantly reduce the risk of damage in case of a DDoS attack from third-party users. For cases when constantly registered information will be received from a registered user, the fiscal data operator enters blocking messages from this user, immediately notifying the user of the problem with the message “SERVER BURNED CONNECTION”, which is transmitted from the fiscal data operator server to the cash register and in the user's personal account. If the processing of information from the cash register at the operator of fiscal data passes without comment, the corresponding identifier of the fiscal data operator confirming that the tax authorities received the information transmitted by the cash register to the cash register.

The method of operation of cash registers with the function of transmitting information to the tax authorities through the fiscal data operator in the absence of a stable communication channel on the Internet and the threat of a DDoS attack, according to the claimed invention, consists in pre-registering the parameters of the cash register user with the fiscal data operator through personal account, generating a report on the registration of cash registers on the basis of the data that was entered by users through the personal account, in the direction The data from the cash register data on cash payments and the fiscal characteristic of a message to the server of the fiscal data operator via communication channels, a two-step check by the operator of fiscal data at the beginning of the registration parameters entered into the personal account. If this check is not successfully passed, the server breaks the connection with the cash register with the notification "SERVER BROKEN CONNECTION". If the check is successfully passed, the server checks the entire message and a special identifier (the fiscal indication of the message guaranteeing the authenticity of the message), then deciding whether to allow or prohibit the generation of the fiscal signature of the operator, save the information sent to the server of the fiscal data and transfer the data together with the fiscal sign of the operator to the tax authorities, the tax authorities check the fiscal sign of the operator, followed by By deciding whether to accept information from the tax authority or prohibit access, when authorizing acceptance of information from the fiscal data operator, the tax authority sends a message to the operator, which in turn generates a fiscal confirmation sign and sends it to the cash register, which records the fiscal confirmation sign and removes intermediate values from memory. When the Internet is disconnected, the cash register records electronically the information about cash payments in the cash register memory block and the fiscal drive with the formation of the fiscal message feature, produces a print of the cash voucher (strict reporting form) with the fiscal sign of the document. When the connection is restored, the cash register sends to the servers of the fiscal data operators the accumulated information on cash settlements, with the required parameters entered during registration in the personal account. After receiving the fiscal data on the operator's server, if the received information matches the information registered in the personal account, the entire message is checked for accuracy, which is performed using a special identifier - the fiscal indication of the message. In the case of the validity of the information sent, this information is signed by the fiscal sign of the operator and transferred from the operator of the fiscal data to the tax authority, which in turn is checked by the technical means of the tax authority by checking the fiscal sign of the operator. In case of reliability of the information sent, the tax authority sends a confirmation of acceptance of information to the operator of fiscal data, and the operator of fiscal data using the technical means of the operator of fiscal data generates a fiscal confirmation sign and sends a message to the cash register, the cash register receives the fiscal sign from the operator confirmation, sends to the fiscal drive, in which there is a check of the fiscal confirmation sign. If the verification confirms the validity of the fiscal indication of confirmation from the operator of fiscal data, the fiscal indication of the confirmation is recorded in the fiscal drive and the cash register a corresponding printed document is generated, which is printed to the printer, and the cash register sends information to the owner (user) cash register equipment that previously transferred from the cash register equipment fiscal data successfully adopted by the tax authority.

In case of failure of the fiscal data operator to receive the received information, the connection is broken and a message is sent to the cash register and to the personal account of the message “SERVER Crashed CONNECTION”. As a result, fiscal documents by the operator of fiscal data from cash registers are no longer accepted.

In case of violation of the connection of the cash register with the tax authorities or the absence of receipt of fiscal documents from the server side of the fiscal data operator, the user of the cash register shall be informed in the following ways:

- print the relevant information on the printer, and after 5 minutes - print a message at intervals of 1 minute

- obligatory sending to the user a notification by e-mail and (or) via instant messengers (Viber, WhatsApp, Telegram, LINE and others) information on the number of unsent checks and the time of the last of the unsent,

The claimed invention is illustrated by drawings, in which:

Figure 1 shows the structure of cash registers.

FIG. 2 shows a functional diagram of the claimed method.

Cash register equipment 1 contains an internal power supply 2, to which battery 5 is connected. To charge battery 5, an external power supply 14 is used. In the case of the absence of a battery 5, cash register equipment 1 can operate from an external power supply 14, and in the absence of external power supply 14 - from the battery 5. In the internal power supply 2, the external voltage is converted and stabilized, which comes from the external power supply 14. After the voltage stabilizes, the power from the internal power supply unit 2 is transferred to the accumulator 5, which is then fed to the central processor with the real-time clock 3, memory block 7, printing device 10, display unit 11, fiscal drive 4, communication modules 6, input-output device 13. To the central processor with clock real-time 3 connected fiscal drive 4, memory block 7, backup battery 8 (in case of complete shutdown of the external power supply 14 and battery 5), keyboard 9, printer 10, display unit 11, communication modules (GSM / GPRS / 3G / 4G / LTE, Wi-Fi, Bluetooth, etc.) 6, device about IO (RS, USB, Ethernet, etc). 13. The memory unit 7 includes various memory chips that may be non-volatile, and removable. Backup battery 8 provides emergency power to the CPU with a real-time clock 3. Communication modules 6 are connected to antennas 12. External devices 16, which are external keyboards, scanners, can be connected to I / O device 13, as well as to communication modules 6. printers, payment terminals, displays and other devices operating both independently and under the control of cash registers, through which the cash registers transmit and (or) receive information. In addition, computer devices 18 are connected to the I / O device 13 and the communication modules 7, which in addition to exchanging information with the servers of fiscal data operators 15 can control the operation of cash register equipment 1. Communication modules 6 (via antennas 12), the input device - output 13 (independently or through computer devices 18) have communication channels for exchanging information with the servers of fiscal data operators 15. The 15 fiscal data operators servers 15 (OFD servers) include the operator’s technical facilities data sources, as well as communication channels for exchanging with tax service servers 17, which also use technical means of tax authorities to work with servers of fiscal data operators.

At the same time, in the cash register equipment used as part of the automatic device for payments, the printing device may be located outside the case of the cash register equipment within the case of the automatic device for payments, and when making payments using electronic payment methods on the Internet, the printer may be absent or be outside the cash register housing within the automatic settlement device housing. The cash register described above checks the registration data, including checking the check number of the registration cash register number, which ensures that the user has entered the registration number into the cash register; provides at the time of calculation the receipt of information about the amount of calculation from an external device; transfers the fiscal data to the fiscal drive; ensures the formation of fiscal documents in electronic form; eliminates the possibility of the formation (printing) of a cash voucher (a strict reporting form), a correction cash receipt (a strict accounting reporting form) containing information on more than one calculation attribute; provides the ability to transfer fiscal documents generated using the fiscal drive, to the operator of fiscal data immediately after writing fiscal data to the fiscal drive, including the possibility of such transfer in encrypted form, as well as the possibility of retransmitting unsent fiscal documents (for which no confirmation of the operator has been received) ); provides printing of fiscal documents; provides the ability to print on a cash receipt (strict reporting form) of a two-dimensional bar code containing, in a coded form, the details of checking a cash receipt or a strict reporting form (the date and time of the calculation, the number of the fiscal document, the sign of the calculation, the amount of the calculation, the number of the fiscal accumulator, the fiscal the sign of the document) in a separate selected area of the cash voucher or a form of strict reporting; receives from the operator’s technical means of the fiscal data the operator’s confirmation, including in encrypted form; informs the user about the absence of confirmation of the operator of the transmitted fiscal document to the tax authorities in electronic form through the operator of fiscal data, as well as about malfunctions in the operation of cash registers; provides the tax authority with the possibility of printing the fiscal document “report on the current stable communication channel of the state of settlements” at any time provides the ability to search for any fiscal document recorded in the fiscal drive by its number and its printing on paper and (or) transfer in electronic form; executes data exchange protocols. In addition, in the case of a customer (customer) providing the user to the user, the cash register equipment, before calculating the subscriber number or e-mail address, sends a cash voucher or a strict reporting form in electronic form to the customer (customer) to the provided subscriber number or e-mail address. During the operation of cash registers, disconnection of Internet communication channels may occur, and, consequently, disconnection from the servers of fiscal data operators, which may lead to temporary blocking of cash registers and (or) inspections by tax authorities. Therefore, it is necessary to track whether the confirmation is received from the operator or not, that is, whether the Internet is available or not. It also requires protection from DDoS attacks, and the server’s recognition of the fiscal data operator, whether information comes from a registered user or not.

The fiscal drive provides counteraction to information security threats (fiscal data); has the ability to encrypt fiscal documents transmitted to the operator of fiscal data in electronic form, and decrypt received from the operator of fiscal data confirmation of the operator; provides the formation of the fiscal characteristic of documents using the key of the fiscal indication of documents (hereinafter referred to as the document key), as well as the generation of the fiscal indication of messages and verification of the fiscal indication of confirmation using the fiscal indication of messages (hereinafter –the message key); provides authentication and validation of operator confirmations, protected by a fiscal confirmation feature; provides a one-time entry in its memory of the registration number of the cash register and the tax identification number of the user; provides multiple recording in its memory of information about the operators of fiscal data and other information entered into the cash register when generating the registration report; generates a fiscal characteristic for each fiscal document; eliminates the possibility of forming a fiscal indication for fiscal documents with a shift of more than 24 hours, with the exception of the report on the closing of the shift; provides an uncorrectable entry in its memory of the established list of fiscal data and non-volatile storage of this fiscal data; encrypted form for subsequent transfer to any operator of fiscal data; provides the ability to receive fiscal data and fiscal documents, including confirmation of the operator received from the operator of fiscal data, including in encrypted form, their decryption, validation of the fiscal characteristic, as well as transfer to the central processor of fiscal data and fiscal documents; has a non-volatile timer to exclude simultaneous designation of an array of fiscal documents "back" number; fixes in the counter of fiscal documents the number of fiscal documents and in the shift counter of the number of shift opening reports for which the fiscal accumulator generated a fiscal indication; generates summary information about the amounts of calculations indicated in cash vouchers (strict reporting forms) and cash vouchers for correction (vigorous reporting forms for the correction) for generated shift closure reports, fiscal drive closure reports and reports on the current status of settlements; begins the formation of the fiscal characteristic of each fiscal document with an increase in the reading of the counter of fiscal documents by one unit; excludes the possibility of forming a fiscal characteristic for a cash voucher or a strict reporting form if the time interval between the formation of a fiscal characteristic for a report on opening a shift and the first cash voucher or the first form of strict reporting in this change or the time interval between the formation of a fiscal characteristic for two cash checks or two forms of strict reporting in a row, determined on the basis of information about the moments of formation of these fiscal documents, transferred to the cash register It differs by more than five minutes from this period of time determined by the timer of the fiscal drive (this solution eliminates the possibility of a large array of information being formed by the attackers to quickly load the fiscal drive in real time) ); eliminates the possibility of generating a fiscal characteristic for fiscal documents after the expiration of the key of the fiscal indication and if after a fixed number of days from the formation of the fiscal indication for the fiscal document will not receive confirmation of the operator for this fiscal document; in case of the impossibility of forming a fiscal sign and (or) of its verification, it sends information to the central processor about the impossibility of forming a fiscal sign and (or) of its verification; has a document key and a message key with a length of at least 256 bits; provides the ability to read fiscal data recorded in its memory.

The fiscal drive provides storage of the following fiscal documents in an unchangeable form of the requisites:

- registration report;

- report on the change of registration parameters;

- report on the opening of the shift;

- cash voucher (form of strict reporting);

- cash voucher correction (form of strict reporting of correction);

- report on the closing of the shift;

- report on the closure of the fiscal drive;

- report on the current status of calculations;

- confirmation of the operator.

Operator confirmation contains the following details:

- the name of the fiscal document (when stored in the memory of the fiscal drive and when the operator sends the fiscal data in electronic form, instead of the name of the fiscal document, the form of the fiscal document is indicated),

- taxpayer identification number of the operator of fiscal data,

- fiscal sign of the operator,

- the factory number of the fiscal accumulator of the cash register, for which the operator’s confirmation is generated,

- the number of the fiscal document to which the statement of the operator relates,

- date and time when the operator receives the fiscal data of the fiscal document to which the statement of the operator relates,

- fiscal evidence of confirmation.

Before the start of the settlement, the cash register forms a report on the opening of the shift, and at the end of the settlement, a report on the closing of the shift. At the same time, a cash voucher (a strict reporting form) is not formed later than 24 hours from the time of the report on the opening of the shift.

The fiscal document immediately after its formation in the cash register is sent by the cash register equipment to the technical means of the fiscal data operator, and if the results of the verification of user registration data are positive in the personal account of the fiscal data, the fiscal indication of the message that protects this fiscal document is checked held immediately after its receipt, the technical means of the fiscal data operator form the confirmation of the operator iskalnyh data, protect it a sign of fiscal confirmation and immediately send it to the check-out equipment. If the confirmation of the operator of the fiscal data is not received, the cash register resubmits to the technical means of the operator of the fiscal data a fiscal document for which no confirmation of the operator of the fiscal data has been received. If the registration data in the sent message do not match, the server breaks the connection, with the error "SERVER BROKEN CONNECTION". This message is transmitted to the cash register, and indicates the emergence of a technical reason for receiving and processing fiscal data on the side of the fiscal data operator. Cash registers on the previously described algorithm informs the user about the problems with the connection of cash registers with the tax authorities.

When making corrections to calculations that were made earlier, a cash receipt of the correction is formed (a strict reporting form of the correction) after the formation of the report on the opening of the shift, but no later than the generation of the report on the closing of the shift.

The formation of a fiscal sign and verification of its reliability, as well as encryption of a fiscal document and its decryption is carried out using an identical (symmetric) key of a fiscal sign and a cryptographic conversion algorithm using such a key of a fiscal sign (symmetric cryptographic algorithm). The document key and message key used in the fiscal drive are unique for each instance of the fiscal drive. Validation of fiscal data protected by the fiscal characteristic of a document is carried out using the fiscal indication checker of the document containing a copy of the master key that was used in the manufacture of the document key contained in the fiscal drive (hereinafter referred to as the document master key).

The document's fiscal feature checker allows you to create a document key using the document master key, which is identical (symmetrical) to the document key contained in the fiscal drive, using which the fiscal document feature was generated and checked by this fiscal document checker. Validation of fiscal data protected by the fiscal message feature generated by the fiscal drive is performed using the fiscal message feature checker containing a copy of the master key that was used in the manufacture of the message key contained in the fiscal drive (hereinafter referred to as the message master key). The fiscal message feature checker allows using the message master key to generate a message key identical (symmetrical) to the message key contained in the fiscal drive, using which the fiscal message feature was generated, which is checked by this fiscal message checker.

The formation of the fiscal sign of the operator means the formation of the fiscal sign of the operator using the key of the fiscal sign of the operator (hereinafter - the key of the operator), which is formed by this means of forming the fiscal sign using a copy of the master key of the fiscal sign of the operator (hereinafter referred to as the master key of the operator) contained in This tool for the formation of the fiscal trait.

Validation of fiscal data in the confirmation of the operator of fiscal data protected by the fiscal sign of the operator is carried out in the cash register using the operator's fiscal sign check tool containing the operator's master key, which allows to form the key of the operator using which the fiscal sign of the operator was formed.

The formation of a fiscal sign of confirmation by means of forming a fiscal sign of confirmation is carried out using the message key, which in turn is formed by this means of forming a fiscal sign using a copy of the master key of the message contained in this means of forming a fiscal sign. Validation of fiscal data in the operator's confirmation, protected by the fiscal confirmation feature, is performed using the fiscal drive and message key.

The user of the cash register through the personal account of the operator of fiscal data (CRF) makes a preliminary registration of the main parameters of the cash register equipment. The cash register generates a registration report in which the previously programmed parameters appear through the personal account. The registration report is protected from change by means of a fiscal drive, which generates a fiscal document with the fiscal indication of the message, and the cash register sends this report to the operator of fiscal data. The operator of the fiscal data after checking the programmed parameters checks the validity of the fiscal characteristic of the message. If the fiscal sign is valid, then the fiscal data operator writes the fiscal document in the memory, generates the fiscal sign of confirmation and sends it to the cash register. The cash register receives a fiscal confirmation mark from the operator of fiscal data, checks it and if the fiscal mark of confirmation is valid, it writes it to the fiscal drive. The operator of the fiscal data forms the fiscal sign of the operator and sends it along with the fiscal document received from the cash registers to the tax authority. The tax authority checks the fiscal attribute of the operator and, if it is valid, writes the fiscal document to memory, and sends confirmation to the fiscal data operator. In the absence of the Internet, the cash register accumulates in its memory and in the memory of the fiscal drive all non-transferred fiscal documents, informs the consumer (owner) of the cash register on the number of non-transmitted fiscal documents, as well as the number of not received confirmations of transferred cash checks (forms of strict reporting) and other fiscal documents from the operator of fiscal data, working time without the Internet. Informing is performed by sending a periodic audio signal (after 5 minutes), outputting a permanent message to the display unit indicating the number of uncommitted checks and the time of the last unsent transfer, printing the relevant information on the printer, and also sending it through the communication modules or through the input / output unit to the user in the form of SMS and / or messages via instant messengers and / or e-mail and / or through other messages about the problems encountered with the transfer of fiscal data to tax authorities s to the owner of cash registers had plenty of time to localize the problem. Since the short message service does not depend on the presence / absence of a communication channel via the Internet, and communication with instant messengers or the postal service can be carried out through a communication module without using the Internet directly on the CCP (via Bluetooth, for example), this means that the cash register The technician can notify the user regardless of the presence / absence of the Internet in the cash register itself.

The proposed method of operation of cash registers will create conditions for raising the awareness of consumers using cash registers, will increase the reliability and security of work on communication channels in the event of their unstable operation (random switching on and off at an unpredictable time and for an indefinite period), will allow to increase protection against DDoS-attacks, to create a modern automated control system for the use of cash registers by the tax authorities, which paradise will be able to carry out in an automated mode, along with the collection of information, an analysis of the completeness of the accounting of revenue in order to identify areas of risk of committing offenses and the subsequent point-based implementation of checks.
