Permanent mass storage devices such as may be included. Here, a permanent large-capacity recording device such as a ROM, SSD, flash memory, or disk drive may be included in the electronic device 110 or the server 150 as another permanent recording device separated from the memories 211 and 221. Good. The memories 211 and 221 include an operating system and at least one program code (for example, a browser installed and executed in the electronic device 110 and an application installed in the electronic device 110 for providing a specific service). Etc.) may be recorded. Such software components may be loaded from a computer-readable recording medium different from the memories 211 and 221. Such another computer-readable recording medium may include a computer-readable recording medium such as a floppy (registered trademark) drive, a disk, a tape, a DVD / CD-ROM drive, and a memory card. In other embodiments, the software components may be loaded into the memories 211 and 221 through the communication modules 213 and 223 that are not computer-readable recording media. For example, the at least one program is a computer program (for example, the above-described example) that is installed by a file provided by a file distribution system (for example, the above-described server 160) that distributes an installation file of a developer or an application via the network 170. May be loaded into the memories 211 and 221 based on the application.

  The processors 212, 222 may be configured to process computer program instructions by performing basic arithmetic, logic, and input / output operations. The instructions may be provided to the processors 212, 222 by the memories 211, 221 or the communication modules 213, 223. For example, the processors 212, 222 may be configured to execute instructions received in accordance with program codes recorded in a recording device such as the memories 211, 221.

  The communication modules 213 and 223 may provide a function for the electronic device 110 and the server 150 to communicate with each other via the network 170, and the electronic device 110 and / or the server 150 may be another electronic device (for example, , The electronic device 120) or another server (for example, the server 160) may be provided. As an example, a request generated by the processor 212 of the electronic device 110 according to a program code recorded in a recording device such as the memory 211 may be transmitted to the server 150 via the network 170 under the control of the communication module 213. On the contrary, a control signal, a command, a content, a file, or the like provided in accordance with the control of the processor 222 of the server 150 is received by the electronic device 110 through the communication module 223 and the network 170 through the communication module 213 of the electronic device 110. It's okay. For example, the control signal, command, content, file, etc. of the server 150 received through the communication module 213 may be transmitted to the processor 212 or the memory 211, and the content, file, etc. may be further included in the electronic device 110. It may be recorded on a medium (the permanent recording device described above).

  The input / output interface 214 may be a means for interfacing with the input / output device 215. For example, the input device may include devices such as a keyboard, a mouse, a microphone, and a camera, and the output device may include devices such as a display, a speaker, and a haptic feedback device.

  The online reservation system may provide a platform for selling products such as accommodation, air tickets, movies, performances, restaurants, hospitals (medical care), and travel through reservations. Here, the reserved product may mean all items and services that can be sold by reservation.

  In the following, an accommodation facility is described as a representative example of a reserved product, but the present invention is not limited to this.

  In recent years, there are a large number of online channels that sell accommodations. However, from the standpoint of the accommodation sellers, it is difficult to select a specific sales channel, and management issues and the risk of double booking It is extremely difficult to select more than one sales channel.

  In order to solve such a problem, there exists an intermediary company that supports the accommodation facility so that it can be sold through a number of sales channels. However, brokerage fees are borne by the accommodation facility seller, and discussions with the brokerage company and operational costs are borne by the sales channel.

  In order to improve this, the sales channels united with each other to build a common database for accommodations, and use this to collectively manage the inventory of each accommodation company, allowing multiple sellers of each accommodation facility to sell Even if you sell on the channel, you can reduce the risk of double booking.

  In particular, in order to prevent the sales from being concentrated only on a specific company, by using blockchain technology, each sales channel participates in a private blockchain network and shares are managed in common. You can also.

  FIG. 3 is an exemplary diagram for explaining a block chain-based reservation system according to an embodiment of the present invention.

  Referring to FIG. 3, the reservation system 300 may include a database having authority common to the plurality of sales channels 310 to 330 for the accommodation facility of the seller 301. In particular, the reservation system 300 may realize a private block chain network for the reservation sales process of accommodation facilities by sharing a unique key value among the plurality of sales channels 310 to 330.

  The seller 301 of the accommodation facility can create and manage the inventory by connecting to the private block chain network on the reservation system 300, and the sales channels 310 to 330 to which the seller 301 delegates the sales authority for the accommodation facility are provided. The reservation sales process of the accommodation facility may be processed based on a smart contract.

  The reservation system 300 may generate a block for processing the transaction transaction related to the reservation of the accommodation facility according to a unique key value of each sales channel 310 to 330 at regular intervals, and for each block in such a block chain. , Transaction requests regarding reservations received from multiple sales channels 310-330 may be managed and processed.

  The reservation system 300 may implement a centrally managed private blockchain network to process the reservation sales process of accommodation facilities, thereby creating a direct communication environment with the sales channels 310-330. The time required for the reservation sales process can be shortened.

  In the following, a specific embodiment of a method and system for detecting an abuse sales channel in a distributed online reservation system will be described.

  FIG. 4 is a block diagram showing an example of components that can be included in the processor of the server in one embodiment of the present invention, and FIG. 5 is a diagram of what the server executes in one embodiment of the present invention. It is the flowchart which showed the example of the method which can be performed.

  In a reservation system structure using a private blockchain network, since all have the same authority in a common database, there is a risk that the network and data will be tampered with by a malicious sales participant.

  An example of a malicious sales participant (referred to as “Eve”) is as follows:

(1) A participant who arbitrarily modifies the inventory of accommodation facilities on the database.
(2) Participants who create a fake reservation even though no reservation has actually occurred, and prevent other participants from making reservations on the channel.
(3) Participants who operate so that transactions on other participants' channels are voted late.

  A blockchain-based transaction request becomes effective when the corresponding request is included in the block. Each sales channel generates blocks alternately according to a defined rule. However, when the order is Eve, other participants' transactions can be excluded from the corresponding block in addition to the transaction generated by Eve, and the transaction not related to Eve is slowed down.

  In the case of (1), it can be solved as follows: Within the smart contract, the authority that can increase the number of reservations and the authority that can increase the total number of reservations are separated. Although the authority for the number of reservations lies in the contracted sales channel, the authority for the total amount that can be reserved lies with the seller of the accommodation facility, so Eve cannot increase the total amount that can be reserved.

  In the case of (2), it can be solved as follows: Since all transaction records remain in the blockchain data, even if a fake reservation is generated, the accommodation cost of the fake reservation is sold to the corresponding accommodation facility. Must be communicated to the person. Therefore, there is no reason to make a fake reservation. Furthermore, repeated reservations and cancellations can confuse the network, but the seller of the accommodation facility can fully monitor this, resulting in cancellation of the contract.

  Blockchain technology alone cannot provide for (3). This is because the accuracy of the time stamp at the time of block generation and the time of transaction occurrence cannot be guaranteed.

  In the present invention, in order to prepare for the case of (3), the block generation time and the transaction occurrence time may be designed to be accurate within the error range, and the transaction completion time required for the transaction request included in the block is within a normal range. You may detect when it exceeds.

  As components for this purpose, the processor 222 of the server 150 may include a block generation unit 410, an abuse detection unit 420, and a sanctioning unit 430, as shown in FIG. Depending on the embodiment, components of processor 222 may optionally be included or excluded from processor 222. Also, in some embodiments, the components of processor 222 may be separated or merged to represent the function of processor 222.

  Such a processor 222 and components of the processor 222 may control the server 150 to execute steps 510 to 530 included in the abuse detection method of FIG. For example, the processor 222 and the components of the processor 222 may be implemented to execute instructions from operating system code and at least one program code included in the memory 221.

  Here, the constituent elements of the processor 222 may be representations of different functions (differential functions) of the processor 222 that are executed by the processor 222 in accordance with instructions provided by the program code recorded in the server 150. For example, the block generation unit 410 may be used as a functional representation of the processor 222 that controls the server 150 in accordance with the above-described instructions so that the server 150 generates a block for distributed processing of transaction transactions related to reservations.

  The processor 222 may read necessary instructions from the memory 221 loaded with instructions related to the control of the server 150. In this case, the read instructions may include instructions for controlling the processor 222 to perform steps 510-530 described below.

  In step 510, the block generation unit 410 applies the block chain technology to a plurality of sales channels having the sales authority for the accommodation facility of the seller, and alternates with each sales channel according to a predetermined rule. A block including a unique hash value of the corresponding sales channel can be generated. The block generation unit 410 may generate a block for distributed processing of a transaction related to a reservation for each sales channel at regular intervals (for example, 1 second). At this time, one of the block generation rules is that all the health check transactions periodically transmitted from other sales channels must be included in the block generated by the sales channel. Each health check transaction includes a unique hash value for each sales channel. At this time, all the blocks include the unique hash value of the sales channel that generated the block. Such hash values can be replaced with numbers. In addition, all sales channels, that is, all participants corresponding to each node constituting the private block chain network have a unique key value, which can also be replaced with a number. Another one of the block generation rules is to generate the next block with a sales channel that includes the unique key value closest to the hash value of the previous block when generating the next block. For example, in a situation in which the A channel with a key value of 2, the B channel with 10, the C channel with 11, and the C channel with 11 participate, if the hash value of the 256th block is 10, the 257th block is the key The value is generated by the C channel whose value is 11 closest to the hash value 10 of the previous block (256th block). As described above, the block generation unit 410 alternately generates a block for each sales channel, but generates a next block using a sales channel having a key value closest to the hash value of the previous block. In other blockchains, blocks are generated by all sales channels, and there are no rules on who should generate a particular block. In such a case, more than one channel can generate a particular block in the same order, and one block is selected by competition. Since such a competition process requires a certain amount of time, there is a problem in that the transaction confirmation time is delayed. In the reservation system using the block chain according to the present invention, in order to reduce the delay time caused by various factors, all the sales channels recognize each other's key values so that the sales channels do not compete for block generation. Apply a private blockchain network.

  In step 520, the abuse detection unit 420 detects an abuse channel that is operated so that a transaction in another sales channel is delayed after a plurality of sales channels having sales authority for the seller's accommodation. Can do. The abuse detector 420 can determine whether the corresponding block is operated based on whether there is a health check transaction received from all other sales channels in the block generated by each sales channel. . Each health check transaction cannot be manipulated because it contains a unique hash value for each sales channel. If there is no health check transaction for all sales channels in the block, the block is regarded as an operated block, and the sales channel that generated the block can be estimated as an abuse channel.

  In particular, the time stamp recorded in the block should not be more than a certain time (for example, 2 seconds) from the point of arrival at the server of each sales channel. Detect. Each sales channel may generate a transaction transaction by recording a time stamp in a transaction request related to a reservation by a user of the reservation service. At this time, the transaction request may include all acts that affect the inventory of the accommodation facility as requested by the user, such as a reservation request or a cancellation request. A request for a blockchain infrastructure becomes effective when a transaction transaction according to the request is included in the block. A sales channel that generates a block is a transaction in which a certain period of time (for example, 2 seconds) of valid transaction transactions included in the block has elapsed, that is, a transaction that marks an old transaction transaction (hereinafter, “mark transaction”). May be additionally generated. An old transaction transaction may mean a transaction request in which a time equal to or greater than a predetermined magnification (for example, two times) has passed from a cycle in which blocks are generated. For example, when a block is generated periodically once every second, a transaction transaction generated two seconds before the current block is generated becomes an old transaction transaction.

  Referring to FIG. 6, each sales channel compares the time when the block 601 is generated with the time when the transaction transaction 602 is generated, and the transaction transaction 602 in which the generation time equal to or greater than a certain factor has passed than the block generation cycle. A mark transaction 603 may be added to. For example, in a block chain in which a block 601 is generated every second, a transaction transaction 602 that has passed twice (2 seconds) or more than the block generation cycle (1 second) may be targeted. Since the transaction transaction 602 generated at “2018-08-01 T09: 0: 02” two seconds ago exists in the block 601 generated at “01 T09: 00: 00”, the mark transaction 603 is added. become. In FIG. 6, the mark transaction 603 is shown on the same line as the specific transaction transaction 602 whose generation time is old. However, this is for convenience of explanation, and the mark transaction 603 is generated separately from the transaction transaction 602. It is.

  In this way, there is a high probability that the old transaction transaction is not included in the block in the previous block. The abuse detector 420 can detect the abuse channel by using the difference between the block generation time and the transaction transaction generation time included in the block. Since a mark transaction may be added to some transaction transactions due to a network transmission problem etc., it is difficult to say that everything with a mark transaction added is an abuse channel, but this phenomenon is repeated Can be estimated as an abuse channel. As an example, the abuse detection unit 420 obtains a numerical value based on the number of mark transactions per a predetermined number of blocks (mark per block value), and detects a sales channel having a standard deviation and a certain value or more as an abuse channel. You can do it. At this time, if the standard deviation based on the number of mark transactions is equal to or greater than a certain value for the same sales channel, the abuse detector 420 finally becomes an abuse channel when it is repeated a certain number of times (for example, three times). It may be determined.

  The difference between the sights channel and the general channel can be explained as follows.

  When sales channels A, B, C, D, and E who have sales rights to the merchant's accommodation use the same algorithm and average on a weekly basis, an average of 9 transactions per 100 blocks Assume that it is marked. At this time, it is assumed that the sales channel E is an abuse channel among the sales channels A, B, C, D, and E.

  In the case of the normal channel A, the number of marks of the transaction related to the other sales channel and the transaction related to the principal channel are similar. For example, when the number of marks existing per 100 blocks for each sales channel is A-7, B-9, C-10, D-9, E-10, the average is 9, and the standard deviation is 1.1. It becomes. Although the number of trade marks associated with sales channel A appears to be small, there is no significant difference from other companies.

  In the case of the abuse channel E, there is a very large difference between the number of marks of the transaction related to the other sales channel and the transaction related to the principal channel. For example, when the number of marks existing in 100 blocks for each sales channel is A-3, B-9, C-10, D-13, E-10, the average is 9, and the standard deviation is 3.2. Become. At this time, it is assumed that the abuse channel E is hostile to the sales channel D.

  Referring back to FIG. 5, in step 530, the sanctions unit 430 sets a penalty for sales authority as a sanctions for a sales channel detected as an abuse channel among a plurality of sales channels having the sales authority for the seller's accommodation. Can be applied. As an example, the sanctioning unit 430 may sanction a transaction related to a sales channel detected as an abuse channel so that the transaction is not included in the block for a certain period (eg, two days). Also, the sanction unit 430 may provide information on the transaction transaction in which the mark transaction has been generated by the management tool of the seller of the accommodation facility, and also provide information on the sales channel that has generated the previous block of the corresponding block. Good. The marked transaction transaction may be considered as an abuse channel because of the high probability that it was not included in the previous block. The merchant management tool may include the ability to selectively notify a suspected sales channel as an abuse channel. At this time, the sanctions unit 430 may deprive the sales authority of a specific sales channel based on the notice of the seller and may be expelled from the online reservation system network as an abuse channel. The sanctioning unit 430 may add a penalty for the sales authority of the accommodation facility to the abuse channel found by the notification of the seller and the detection of the sales channel participating in the reservation sale of the accommodation facility of the seller. The appropriate standard deviation guidelines and the specific penalties to be added if they are not followed can be determined directly by discussion between the participants participating in the reservation sale of the seller's accommodation, and the guidelines established by participation And the penalty may be reflected in the sanctions unit 430.

  Thus, according to the embodiment of the present invention, an online reservation system using blockchain technology can detect an abuse channel that harms the network and data, and can sanction the sales authority of the corresponding channel.

  The apparatus described above may be realized by hardware components, software components, and / or a combination of hardware and software components. For example, the apparatus and components described in the embodiments include a processor, a controller, an ALU (arithmetic logic unit), a digital signal processor, a microcomputer, an FPGA (field programmable gate array), a PLU (programmable logic unit), a microprocessor, Or it may be implemented using one or more general purpose or special purpose computers, such as various devices capable of executing and responding to instructions.
