Good. In addition, the memories 211 and 221 contain an operating system and at least one program code (for example, a browser installed and executed in the electronic device 110 or an application installed in the electronic device 110 to provide a specific service. Code for etc.) may be recorded. Such software components may be loaded from a computer-readable recording medium separate from the memories 211 and 221. Such other computer-readable recording media may include computer-readable recording media such as floppy® drives, disks, tapes, DVD / CD-ROM drives, memory cards, and the like. In other embodiments, software components may be loaded into memory 211 and 221 through communication modules 213 and 223 that are not computer readable recording media. For example, at least one program is a computer program installed by a file provided via network 170 by a file distribution system (eg, server 160 described above) that distributes developer or application installation files (eg, described above). It may be loaded into the memory 211 or 221 based on the application.

Processors 212 and 222 may be configured to process instructions in a computer program by performing basic arithmetic, logic, and input / output operations.

An online booking system may provide a platform for selling products such as accommodation, airline tickets, movies, performances, restaurants, hospitals (medical care), travel, etc. through booking. Here, the reserved product may mean a product that includes all the goods and services that can be sold by reservation.

The following describes accommodation facilities as a typical example of reserved products, but the present invention is not limited to this.

In recent years, there are a large number of online channels that sell accommodations, but from the standpoint of accommodation sellers, it is difficult to select a specific sales channel, due to management problems and the danger of double booking. Choosing more than one sales channel is also extremely difficult.

To solve these problems, there are intermediaries that help accommodations to be sold through multiple sales channels. However, from the standpoint of the seller of the accommodation facility, the brokerage fee will be borne, and from the standpoint of the sales channel, the discussion with the brokerage company and the operating cost will be borne.

In order to improve this, sales channels are united to build a common database for accommodation facilities, and by using this to collectively manage the inventory of each accommodation company, multiple sales of each accommodation facility seller You can reduce the risk of double booking by selling on the channel.

In particular, in order to prevent sales from being biased toward a specific company, each sales channel participates in a private blockchain network (private blockchain network) and manages inventory in common by using blockchain technology. You can also do it.

FIG. 3 is an exemplary diagram for explaining a blockchain-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 a plurality of sales channels 310-330 for the accommodation facility of the seller 301. In particular, the reservation system 300 may realize a private blockchain network for the reservation sales process of the accommodation facility by sharing unique key values among the plurality of sales channels 310 to 330.

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

The reservation system 300 may generate blocks for processing transaction transactions related to accommodation reservations by a unique key value of each sales channel 310-330 at regular intervals, and for each block in such a blockchain. , You may manage and process transaction requests for reservations received from multiple sales channels 310-330.

The reservation system 300 may realize a centrally managed private blockchain network to process the reservation sales process of the accommodation facility, which creates a direct communication environment with the sales channels 310 to 330. The time required for the reservation sales process can be shortened.

Hereinafter, a method of detecting an Abuse sales channel in a distributed online reservation system and a specific embodiment of the 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 block diagram of what the server executes in one embodiment of the present invention. It is a flowchart which showed the example of the possible method.

In a reservation system structure using a private blockchain network, there is a risk that the network and data will be tampered with by malicious sales participants because they all have equal authority over a common database.

An example of a malicious sales participant (referred to as "Eve") is as follows.

(1) Participants who arbitrarily modify the inventory of accommodation facilities on the database.
(2) A participant who creates a fake reservation even though no reservation has actually occurred and interferes with making a reservation on another participant's channel.
(3) Participants who operate so that transactions on other participants' channels are delayed.

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

In the case of (1), it can be solved as follows: In the smart contract, the authority to increase the number of reservations and the authority to increase the total number of reservations are separated. Eve cannot increase the total number of reservations, as the authority over the number of reservations lies with the contracted sales channel, but the seller of the accommodation has authority over the total number of reservations.

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 due to the fake reservation will be sold at the corresponding accommodation facility. Must be communicated to the person. Therefore, there is no reason to make a fake reservation. In addition, repeated bookings and cancellations can disrupt the network, which can result in contract cancellations as accommodation sellers can adequately monitor this.

Blockchain technology alone cannot prepare for case (3). This is because the accuracy of the time stamp (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 (3), the block generation time and the transaction occurrence time may be designed to be accurate within an error range, and the transaction completion time required for the transaction request to be included in the block may be within the normal range. You may detect cases that exceed.

As a component for this purpose, the processor 222 of the server 150 may include a block generation unit 410, an abus detection unit 420, and a sanction unit 430, as shown in FIG. In some embodiments, the components of processor 222 may be selectively included or excluded from processor 222. Also, depending on the embodiment, the components of processor 222 may be separated or merged to represent the functionality of processor 222.

Such processor 222 and the components of processor 222 may control the server 150 to perform 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 an instruction by the code of the operating system included in the memory 221 and the code of at least one program.

Here, the components of the processor 222 may be representations of different functions of the processor 222 that are executed by the processor 222 according to the instructions provided by the program code recorded in the server 150. For example, the block generator 410 may be used as a functional representation of the processor 222 that controls the server 150 according to the instructions described above so that the server 150 generates blocks for distributed processing of transaction transactions related to reservations.

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

In stage 510, the block generator 410 applies blockchain technology to a plurality of sales channels that have sales authority over the seller's accommodation, thereby alternating by each sales channel in accordance with predetermined rules. It is possible to generate a block containing a unique hash value of the corresponding sales channel. The block generation unit 410 may generate blocks for distributed processing of transaction transactions related to reservations at regular intervals (for example, 1 second) by each sales channel. At this time, one of the block generation rules is that the block generated by the sales channel must include all health check transactions periodically transmitted from the other sales channels. Each health check transaction contains 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, and such a hash value can be replaced with a number. In addition, all sales channels, that is, all participants corresponding to each node constituting the private blockchain network, have a unique key value, which can also be replaced with a number. The other one of the block generation rules is that when the next block is generated, the next block is generated by the sales channel containing the hash value of the previous block and the closest unique key value. For example, in a situation where channel A having a key value of 2 and channel B having a key value of 10 and channel C having a key value of 11 are participating, if the hash value of the 256th block is 10, the 257th block is the key. The value will be generated by the C channel, which is the closest 11 to the hash value 10 of the previous block (256th block). As described above, the block generation unit 410 alternately generates blocks for each sales channel, but generates the next block by the sales channel having the 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 as to who should generate a particular block. In such a case, two or more channels can generate specific blocks of the same order, and one block is selected by competition. Since a certain amount of time is required for such a competitive process, there is a problem that the time when the transaction is finalized is delayed. In the reservation system using the blockchain 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 your private blockchain network.

In stage 520, the Abuse detection unit 420 detects the Abuse channel that operates so that the transaction on the other sales channel is delayed among the plurality of sales channels that have the sales authority for the seller's accommodation. Can be done. The Abuse detection unit 420 can determine whether or not the block is being manipulated by whether or not there are health check transactions received from all other sales channels in the block generated by each sales channel. .. Each health check transaction contains a unique hash value for each sales channel and cannot be manipulated. If there are no health check transactions for all sales channels in the block, it can be regarded as an manipulated block, and the sales channel that generated the block can be estimated as the Abuse channel.

In particular, the time stamp recorded on the block must not differ by more than a certain time (for example, 2 seconds) from the time when it reached the server of each sales channel, and by utilizing such characteristics, the Abuse channel To detect. Each sales channel may generate a transaction transaction by recording a time stamp on a transaction request regarding a reservation made by a user of the reservation service. At this time, the transaction request may include all actions such as a reservation request and a cancellation request that affect the inventory of the accommodation facility at the request of the user. The blockchain-based request becomes effective when the transaction transaction according to the request is included in the block. The sales channel that generates the block is a transaction that marks (marks) an old transaction transaction after a certain period of time (for example, 2 seconds) has passed among the valid transaction transactions contained in the block (hereinafter, "mark transaction"). ") May be additionally generated. An old transaction transaction may mean a transaction request for which a predetermined multiple (for example, 2 times) or more time has elapsed from the cycle in which the block is generated. For example, when a block is periodically generated once per second, a transaction transaction generated 2 seconds before the time when 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 higher than the block generation cycle elapses. Mark transaction 603 may be added to. For example, in a blockchain in which a block 601 is generated every second, a transaction transaction 602 in which a time equal to or more than twice (2 seconds) longer than the block generation cycle (1 second) may be targeted, and "2018-08-" Since the transaction transaction 602 generated at "2018-08-01 T09: 00: 02" two seconds ago exists in the block 601 generated at "01 T09: 00: 04", the mark transaction 603 will be added. become. In FIG. 6, the mark transaction 603 is shown on the same line as the specific transaction transaction 602 with the old generation time, but this is for convenience of explanation, and the mark transaction 603 is generated separately from the transaction transaction 602. Is.

In this way, old transaction transactions are likely not included in the block in the previous block. The Abuse detection unit 420 can detect the Abuse channel by using the difference between the block generation time point and the transaction transaction generation time point included in the block. Since mark transactions may be added to some transaction transactions due to network transmission problems, it is difficult to say that everything with added mark transactions is an Abuse channel, but if such a 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 block (mark per block value), and detects a sales channel having a difference of a certain value or more from the standard deviation as an Abuse channel. You can do it. At this time, the Abuse detection unit 420 finally becomes the Abuse channel when the standard deviation due to the number of mark transactions is repeated a certain number of times (for example, three times) for the same sales channel. You may determine.

The difference between the Abuse channel and the general channel in terms of numerical values can be explained as follows.

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

In the case of normal channel A, the number of marks of transactions related to other sales channels and transactions related to the principal's 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. The number of marks for transactions related to sales channel A seems to be small, but it is not much different from other companies.

In the case of Abuse Channel E, there is an extremely large difference in the number of marks of transactions related to other sales channels and transactions related to the principal's 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 responds hostilely to the sales channel D.

Again, in FIG. 5, at stage 530, the sanctions department 430 penalizes the sales authority as a sanction for the sales channel detected as the Abuse channel among the multiple sales channels that have the sales authority for the seller's accommodation. Can be applied. As an example, Sanctions Department 430 may sanction transactions associated with a sales channel detected as an Abuse channel so that they are not included in the block for a period of time (eg, two days). In addition, the sanctions department 430 may provide information on the transaction transaction in which the mark transaction was generated by the management tool of the seller of the accommodation facility, and also provide information on the sales channel that generated the previous block of the corresponding block. Good. The marked transaction transaction may be considered as an Abuse channel because it is likely that it was not included in the block in the previous block. The seller's management tool may include the ability to selectively notify the suspected sales channel as an Abuse channel. At this time, the sanctions department 430 may deprive the sales authority of a specific sales channel notified by the seller and expel it from the network of the online reservation system as an abuse channel. The Sanctions Department 430 may impose a penalty on the sales authority of the accommodation for the Abuse Channel found by the seller's notification and the detection of the sales channel that participated in the seller's reservation sale of the accommodation. Through discussions between participants participating in the seller's accommodation reservation sale, appropriate standard deviation guidelines and specific penalties incurred if they are not followed may be directly set, and the guidelines set by participation. And the penalty may be reflected in the sanctions department 430.

As described above, according to the embodiment of the present invention, the online reservation system using the blockchain technology can detect the Abuse channel that harms the network and data, and can sanction the sales authority of the channel.
