In addition, the memory 211, 221 includes an operating system and at least one program code (for example, a code installed in the electronic device 110, a browser running on the electronic device 110, or an application installed in the electronic device 110 to provide a specific service). Can be stored. These software components may be loaded from a computer readable recording medium separate from the memories 211 and 221. Such separate 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 the memory 211, 221 through a communication module 213, 223 that is not a computer readable recording medium. For example, at least one program is a computer program that is installed by files provided by a file distribution system (for example, the server 160 described above) through the network 170 to distribute installation files of developers or applications. It may be loaded into the memories 211 and 221 based on (for example, the above-described application).

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

The online booking system may provide a platform for the sale of goods such as accommodations, tickets, movies, performances, restaurants, hospitals (medical care), and travel through reservations, where the reservation products are all goods or services available for sale through reservations. It can mean comprehensively.

Hereinafter, the accommodation is described as a representative example of the reservation product, but is not limited thereto.

While there are a lot of online channels selling accommodation recently, it is difficult for a property seller to choose a specific sales channel and to choose more than one sales channel due to administrative issues or the risk of double booking. There is also a difficult problem.

To solve these problems, there are brokerage firms that can help sell accommodation in multiple sales channels. However, a brokerage fee may be borne by the seller of the lodging facility, and a discussion and operation fee may be borne by the sales channel.

To improve this, you can create a common database of accommodations by federating between sales channels, which collectively manages inventory for each property to reduce the risk of double booking even if sellers of each property sell on multiple sales channels. Can be.

In particular, in order to prevent a specific company from becoming a focal point, blockchain technology can be used, and each sales channel can participate in a private blockchain network to manage a common inventory.

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 in which a plurality of sales channels 310 to 330 have a common authority with respect to the accommodation of the seller 301. In particular, the reservation system 300 may implement a private blockchain network for the reservation sale process of accommodation by sharing unique key values between the plurality of sales channels 310 to 330.

The seller 301 of the accommodation can connect to the private blockchain network on the reservation system 300 to create and manage inventory, and the sales channel 310-330 to which the seller 301 delegates the selling authority for his accommodation. This smart contract can be used to handle the pre-sale process of the property.

The reservation system 300 may generate a block for processing a transaction transaction related to the reservation of the accommodation with a unique key value of each sales channel 310 to 330 at regular intervals, and a plurality of blocks for each block in the blockchain. The transaction request related to the reservation received from the sales channels 310 to 330 may be managed and processed.

The reservation system 300 may process a reservation sale process of accommodation by implementing a private blockchain network of a central management method, and through this, a reservation communication process may be performed in a direct communication environment with the sales channels 310 to 330. It can save time.

Hereinafter, a specific embodiment of a method and a system for detecting an abusing sales channel in a distributed online reservation system will be described.

4 is a block diagram illustrating an example of components that may be included in a processor of a server according to an embodiment of the present invention, and FIG. 5 is an example of a method that may be performed by a server according to an embodiment of the present invention. It is a flowchart showing.

In the structure of the reservation system using a private blockchain network, all common databases have the same authority, so malicious sales participants can harm the network and data.

An example of a malicious sales participant (called 'Eve') is as follows.

(1) Participants who arbitrarily modify the inventory of accommodation in the database.

(2) A participant who created a fake reservation and prevented it from being made by another participant's channel when no actual reservation occurred.

(3) A participant who manipulates a transaction through another participant's channel to be slow.

A blockchain-based transaction request becomes valid only when the request is included in the block. Each sales channel alternately generates blocks according to a set of rules. However, at the turn of Eve, other participants' transactions may be excluded from the block in addition to the transactions created in Eve, which will delay processing of transactions not related to Eve.

In the case of (1), this can be solved as follows: There is a separation of the right to increase the number of reservations from the smart contract and the right to increase the total number of reservations. The rights to the number of reservations are in the contracted sales channel, but the rights to the total number of bookings are available to the seller of the property. Eve cannot increase the total number of bookings.

In case of (2), it can be solved as follows: Since all transaction records in the blockchain data remain, even if a fake reservation is made, the accommodation cost of the fake reservation must be communicated to the seller of the accommodation. Therefore, there is no reason to make a fake reservation. It can also confuse the network by repeating reservations and cancellations, but it can lead to cancellation of the contract because the property's seller can monitor it sufficiently.

Blockchain technology alone cannot prepare for case (3). This is because it is not possible to guarantee whether the timestamp of the block generation time and the transaction occurrence time is accurate.

In the present invention, it is possible to design a block generation time and a transaction occurrence time to be accurate within an error range in preparation for the case of (3), and detect a case where a transaction completion time in which a transaction request is included in a block exceeds a normal range. have.

As shown in FIG. 4, the processor 222 of the server 150 may include a block generator 410, an abusing detector 420, and a sanction unit 430. In some embodiments, the components of the processor 222 may be optionally included in or excluded from the processor 222. In addition, according to an embodiment, the components of the processor 222 may be separated or merged to represent the functions of the processor 222.

The processor 222 and the components of the processor 222 may control the server 150 to perform steps S510 to S530 included in the abusing detection method of FIG. 5. For example, the processor 222 and the components of the processor 222 may be implemented to execute instructions according to code of an operating system included in the memory 221 and code of at least one program.

Here, the components of the processor 222 may be representations of different functions of the processor 222 performed by the processor 222 according to an instruction provided by the program code stored in the server 150. . For example, the block generator 410 may be a functional representation of the processor 222 controlling the server 150 in accordance with the above-described command so that the server 150 generates a block for processing a transaction related to a reservation. Can be used.

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 command may include a command for controlling the processor 222 to execute steps S510 to S530 to be described later.

In step S510, the block generation unit 410 alternately applies the blockchain technology to the plurality of sales channels having the selling authority for the accommodation of the seller by each sales channel according to a predetermined rule. You can create a block with a unique hash value for the channel. The block generator 410 may generate a block for distributing a transaction transaction related to a reservation by each sales channel at predetermined intervals (for example, one second). At this time, one of the block generation rules should include all of the health check transactions that are periodically transmitted from other sales channels in the block generated by the sales channel. Each self-checking transaction contains a unique hash value for each sales channel. At this time, every block has a unique hash value of the sales channel that created the block, and this hash value can be replaced with a number. In addition, all sales channels, that is, the participants corresponding to each node constituting the private blockchain network, all have unique key values, which can also be replaced by numbers. The other of the block generation rules is generated by the sales channel with the unique key value closest to the hash value of the previous block when generating the next block. For example, if the hash value of the 256th block is 10 in the case where the A channel with the key value 2, the B channel with the 10, and the C channel with the 11 are participating, the 257th block is the previous block (256th block). Generated by the C channel with the nearest 11 hash value of. As described above, the block generation unit 410 may generate blocks by alternating sales channels, but generate 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 made by all sales channels and there are no rules about who should make a particular block. In this case, two or more channels can make a particular block of the same order, and one block is selected through competition. Such a competition process takes a certain time and there is a problem that the time of confirmation of the transaction is delayed. In the reservation system using the blockchain according to the present invention, in order to reduce the delay time of various factors, a private blockchain network in which all the sales channels know each other's key values is applied so as not to compete with the generation of blocks between the sales channels.

In operation S520, the abusing detection unit 420 may detect an abusing channel that manipulates the transaction of another sales channel to be slowly settled among a plurality of sales channels having the selling authority for the accommodation of the seller. The abusing detector 420 may determine whether the block is manipulated based on the existence of a self-check transaction received from all other sales channels in the block generated by each sales channel. Each self-check transaction cannot be manipulated because it contains a unique hash value for each sales channel. However, if there is no self-checking transaction of all sales channels in the block, it can be regarded as a manipulated block and can estimate the sales channel that generated the block as the abusing channel.

In particular, the timestamp recorded in the block should not differ by more than a certain time (for example, 2 seconds) from the time of reaching the server of each sales channel, and the abusing channel can be detected by using such a characteristic. Each sales channel may create a transaction transaction by recording a timestamp in the transaction request associated with the reservation by the user of the reservation service. In this case, the transaction request may include any action that affects the deduction of inventory of the accommodation facility according to the user's request, such as a reservation request or a cancellation request. A blockchain-based request is valid only when a transaction transaction according to the request is included in the block. The sales channel that generates the block adds a transaction (hereinafter referred to as a 'mark transaction') that marks a certain period of time (e.g., 2 seconds), that is, an old transaction transaction, among the valid transaction transactions included in the block. Can be generated as The old trading transaction may mean a transaction request that has passed a predetermined multiplier (eg, 2 times) or more than a period in which a block is generated. For example, if a block is generated periodically once per second, a transaction transaction created two seconds before the current block is called an old transaction transaction.

Referring to FIG. 6, each sales channel compares the time at which the block 601 is generated with the time at which the transaction transaction 602 is generated, and marks for the transaction transaction 602 whose creation time is more than a certain magnification over the block generation period. Transaction 603 may be added. For example, in a blockchain where block 601 is generated every second, it may target a transaction transaction 602 that is more than twice (two seconds) more than the block generation period (one second), and "2018- In the block 601 created at 08-01 T09: 00: 04 ", there is a transaction transaction 602 created at" 2018-08-01 T09: 00: 02 "two seconds ago, so the mark transaction 603 is added. Can be. In FIG. 6, the mark transaction 603 is shown on the same line as the specific transaction transaction 602 having a long generation time, but this is for convenience of description only, and the mark transaction 603 is generated separately from the transaction transaction 602. will be.

This old transaction transaction is likely not included in the block from the previous block. The abusing detector 420 may detect the abusing channel by using a difference between a block generation time and a generation time of a transaction transaction included in the block. Since the mark transaction may be added to some transaction transactions due to network transmission problems, the addition of the mark transaction is not all the abusing channel. However, when this phenomenon is repeated, the abusing channel can be estimated. For example, the abusing detector 420 may obtain a numerical value by using a predetermined number of mark transactions per block, and detect a selling channel that opens at a predetermined value or more in a standard deviation as an abusing channel. At this time, the abusing detection unit 420 may finally determine the abusing channel when the standard deviation according to the number of mark transactions is equal to or greater than a predetermined value for the same sales channel.

The difference between the abusing channel and the normal channel in numerical terms is as follows.

Suppose sales channels A, B, C, D, and E, which have the seller's authority to sell accommodations, are averaged on a weekly basis using the same algorithm, and on average, nine transactions per 100 blocks are marked. In this case, it is assumed that the sales channel E among the sales channels A, B, C, D, and E is an abusing channel.

In the case of normal channel A, transactions related to other sales channels have a similar number of marks related to their own channels. For example, when the number of marks existing per 100 blocks for each sales channel is A-7, B-9, C-10, D-9, and E-10, the average is 9 and the standard deviation is 1.1. The number of marks in a transaction related to sales channel A may be small, but that is not much different from other companies.

In the case of Abusing Channel E, the number of marks in a deal related to another sales channel and a deal related to one's own channel is quite different. For example, when the number of marks existing per 100 blocks for each sales channel is A-3, B-9, C-10, D-13, and E-10, the average is 9 and the standard deviation is 3.2. In this case, it is assumed that the abusing channel E is hostile to the sales channel D.

Referring back to FIG. 5, in step S530, the sanction unit 430 penalties the selling authority as a sanction for the selling channel detected as the abusing channel among a plurality of selling channels having selling authority for the accommodation of the seller. Can be applied. For example, the sanction unit 430 may sanction so that transactions related to the sales channel detected as the abusing channel are not included in the block for a predetermined period (eg, 2 days). In addition, the sanction unit 430 may provide information on the transaction transaction in which the mark transaction is generated through the management tool of the seller of the accommodation facility and may also provide information on the sales channel that generated the block before the block. . The marked transaction transaction can be considered in the abusing channel determination because of the high probability that it has not been included in the block in the previous block. The merchant's management tool may include the ability to selectively report sales channels suspected of abusing channels. In this case, the sanction unit 430 may deprive the sales authority of the specific sales channel by the seller's report and deport it from the network of the online reservation system as an abusing channel. The sanction unit 430 may apply a penalty for the selling authority of the accommodation to the abusing channel found through the seller's report and detection of the sales channel participating in the seller's reservation sale. Through discussions with participants participating in the seller's reservation sale of accommodation, the appropriate standard deviation guidelines and specific penalties for violations can be set directly, and the guidelines and penalties determined by the participants are subject to sanctions 430. Can be reflected in.

As described above, according to embodiments of the present invention, in an online reservation system using a blockchain technology, an abusing channel may be detected that harms the network and data, and a right to sell the channel may be sanctioned.
