Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The hotel reservation platform and hotel management in the prior art are accomplished in two separate systems. System or human errors often occur in the two independent systems, so that the client can successfully place and place an order on the booking platform, but the hotel system does not receive or generate errors, so that the client cannot check in after arriving at a store, and poor user experience is caused. Moreover, settlement of hotel subscribers and settlement of hotels are often not done in real time. Based on this, in the display scheme of the invention, all transaction participants are connected through a block chain network, so as to realize the real-time sharing of hotel reservation information and payment information.
Fig. 1 shows a flowchart of a hotel reservation settlement method based on a blockchain network according to one embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S10: and receiving a room reservation order pushed by the reservation platform.
The room booking order is generated when a user node books a room on a booking platform, the room booking order carries information and booking requirements of the user node, the booking requirements are requirements of the user node on the room to be booked, and the room booking order may include: date of stay, date of departure, type of house reservation, etc.
It should be noted that: in order to improve the authenticity and reliability of the hotel reservation and settlement system based on the blockchain network, when a user node performs reservation, the true identity of the user node is verified, or only a registered user is allowed to perform reservation operation, and when the user node requests to become the registered user, the user node performs identity authentication, in some embodiments, the verification process is as follows: receiving a professional certificate uploaded by a user by a hotel reservation and settlement platform node based on a block chain system; sending a verification request to a certificate authority, wherein the verification request carries the professional certificate; when receiving a verification response returned by the certificate authority after the professional certificate is verified, the hotel reservation and settlement platform node issues user nodes on the blockchain network, such as: when a user applies to become a registered user or a hotel is reserved, the user can download a user node on a management node, a pair of keys is generated by using a key generation interface, the public key is sent to a national legal CA (certificate Authority), after the CA verifies the identity of the user, the public key of the user is digitally signed and a digital certificate is issued, after the user receives the certificate, the user carries out identity confirmation transaction with the management node once, and the fact that the identity is obtained is recorded in the blockchain network, so that the broadcasting of the digital certificate in the blockchain network is completed.
Step S11: determining whether a room meeting the reservation requirement exists, and if so, executing step S12; if not, the order is cancelled, and a message of reservation failure is fed back.
The room required by the reservation refers to the hotel room type selected by the user node on the reservation platform. For example, a user node selects a standard double-person room on a booking platform, a hotel booking and settlement platform node based on a block chain network sends booking requirements to the hotel node, the hotel node confirms the booking requirements, when the hotel node confirms that the vacant standard double-person room exists, the hotel node determines that a room meeting the booking requirements exists, and returns information to the settlement platform, if the hotel node confirms that the vacant standard double-person room does not exist, the hotel booking and settlement platform node based on the block chain network confirms that the booking requirements do not meet, cancels the order, and feeds a message of booking failure back to the user node. By the mode, when the successful booking information returned by the booking platform is obtained, the block chain network realizes order confirmation on the hotel booking and settlement platform based on the block chain network through the consensus mechanism, so that the condition that a customer obtains the successful booking information on the hotel booking platform is avoided, the condition that the order is not synchronized in the hotel management system due to various conditions, and the user experience is improved.
Step S12: and locking the rooms meeting the booking requirements, and returning information of successful booking to the booking platform.
When a room meeting the reservation requirement is locked, the room can not be reserved or used for the third-party user. In addition, the hotel node also locks the rooms meeting the reservation requirement, so that the rooms reserved by the user node can be guaranteed to be possessed necessarily, the rooms meeting the reservation requirement are reserved for the user node well, and the information of successful reservation is returned to the reservation platform, so that the situation that when the hotel system is out of synchronization with the reservation system, the user node successfully reserves on the reservation system, but the hotel system does not reserve rooms for the user is avoided.
In some embodiments, when the booking platform pushes the room booking order, a time interval for receiving information of successful booking can be set, when the returned information is still not received after the time interval is exceeded, the booking failure can be identified, and when the booking failure occurs, the booking platform feeds back the information of the failed booking to the user node.
In some embodiments, after the reservation is successful, the user node may perform a manual operation to pay the cost of the room, for example, enter a bank account of the user node, and pay through the bank account of the user node. Still alternatively, offline payment, for example: and after checking the booking order of the hotel, the user of the user node deals with the hotel in the same place.
In some embodiments, after the hotel returns the booking success information, a payment intelligent contract of a hotel booking settlement platform based on a block chain network can be automatically triggered, the payment intelligent contract is used for executing room fee payment from the fund accounts of the user nodes to the fund account number of the hotel nodes, and the payment execution is triggered through the payment intelligent contract, so that manual operation payment of the user nodes is not needed, and the hotel booking success information is more convenient and quicker. Certainly, when payment is triggered through the payment intelligent contract, a fund account corresponding to the user node needs to be bound on the platform.
Fig. 2 shows a flow chart of a payment intelligent contract in a hotel reservation and settlement method based on a block chain network according to an embodiment of the invention. As shown in fig. 2, a payment intelligent contract includes the steps of:
step S121, the payment amount corresponding to the house fee is frozen on the fund account of the user node, and a payment message is generated.
Wherein, the payment message carries payment amount and room booking order.
In some embodiments, when the balance of the fund account of the user node is less than the payment amount, a prompt message may be further sent to prompt the user node that the balance of the fund account is insufficient.
And step S122, pushing a payment message to the hotel node.
Step S123, the hotel node determines whether the payment amount is correct according to the room reservation order, if so, step S124 is executed, and if not, the order is cancelled;
the payment amount of the payment is frozen before the actual payment, then whether the payment amount is correct or not is confirmed with the hotel node, and when the payment amount is correct, the payment is executed, so that the situations of over-payment and under-payment are reduced. Of course, in some embodiments, when the hotel node detects that there is a multi-payment, low-payment condition, the hotel node may return relevant prompt information prompting the user node to modify the payment amount for the payment and to re-pay.
And step S124, releasing the frozen payment amount on the user node fund account, and transferring the amount from the user node fund account to the hotel node fund account.
In some embodiments, in order to improve security of the payment packet in the transmission process, when the payment packet is transmitted, the booking platform may further encrypt the payment packet, and the hotel node decrypts the payment packet when receiving the payment packet, specifically, on the booking platform, the payment packet is encrypted by using a preset second encryption algorithm to obtain a payment digital fingerprint, the payment packet and the payment digital fingerprint are encrypted by using a public key of the hotel node, and then signed by using a private key of the user node, and pushed to the hotel node. When the hotel node receives the encrypted payment message and the encrypted payment digital fingerprint, the public key of the user node is used for decryption, then the private key of the hotel node is used for decryption, the payment message and the payment digital fingerprint are obtained, the preset second encryption algorithm is used for encrypting the payment message, the second digital fingerprint to be identified is obtained, and when the second digital fingerprint to be identified is the same as the payment digital fingerprint, whether the payment amount is correct or not is determined according to the room booking order, wherein the preset second encryption algorithm can adopt a hash algorithm.
It can be understood that: the encryption and decryption of the payment message are not limited to the above-described manner, and other manners may be adopted, which are not described in detail herein.
Step S13: payment of a house fee for the locked room is received, triggering a split into intelligent contracts.
The intelligent contract division is automatically executed when a preset execution condition is met, manual operation is not needed, and the preset execution condition is that payment is paid for a user node.
Fig. 3 shows a flow chart of intelligent contract division in a block chain network-based hotel reservation and settlement method according to an embodiment of the present invention. As shown in fig. 3, dividing into smart contracts includes the steps of:
step S131, freezing the share amount corresponding to the house fee on the fund account of the hotel node, and generating a share message.
Wherein the dividing message carries a dividing fund and a room reservation order.
Step S132, pushing the divided messages to the nodes of the preset platform.
Step S133, the reservation platform determines whether the share amount is correct according to the room reservation order, if so, the step S134 is executed, and if not, the share is cancelled;
and S134, removing the amount of the frozen house fee on the hotel fund account, and dividing the amount between the booking platform and the hotel nodes according to a preset dividing proportion.
The payment amount paid is frozen before the actual division, then the reservation platform confirms whether the divided amount is correct or not, and when the divided amount is correct, the division is executed, so that the situations of more points and less points are reduced. In addition, when the user node pays, the intelligent contract division is immediately triggered, and the money paid by the user node is firstly frozen in the intelligent contract division and then divided, so that the situation that the money paid by the user node is stolen for the payee is favorably avoided.
In some embodiments, in order to improve the security of the split message in the transmission process, when the split message is transmitted, the hotel may further encrypt the split message, specifically, the split message is encrypted by using a preset first encryption algorithm to obtain a split digital fingerprint, the split message and the split digital fingerprint are encrypted by using a public key of the booking platform, and then signed by using a private key of the hotel node, and pushed to the booking platform node. When receiving the encrypted divided message and the encrypted divided digital fingerprint, the booking platform decrypts the message according to the public key of the hotel node, decrypts the message by using the private key of the booking platform to obtain the divided message and the divided digital fingerprint, encrypts the divided message by using the preset first encryption algorithm to obtain the first digital fingerprint to be identified, and determines whether the divided fund is correct or not according to the room booking order when the first digital fingerprint to be identified is the same as the divided digital fingerprint, wherein the preset first encryption algorithm can be a hash algorithm, and the preset first encryption algorithm is not limited in the embodiment.
It is worth mentioning that: the interactive information between the user node and the booking platform and the interactive information between the booking platform and the hotel node are recorded in the blockchain network, the data of the blockchain network has the characteristic of unchangeability, the situation that the data is artificially modified can be reduced, and the intelligent split contract and the intelligent payment contract are distributed on the blockchain network. The user node, the reservation platform and the hotel node are all used as nodes of a block chain network, respective stacks are established on the respective nodes, functional layers related to respective accounts are arranged in the stacks, specifically, the functional layers comprise a payment application module layer, a transmission layer and an account layer, wherein the payment application module layer is used for managing the payment purpose, the payee, the address, the payment condition and the payment protocol of an order; the transmission layer is used for managing payment protocol formats, payment message transmission and encryption and decryption of the payment messages; the account layer is used for managing fund accounts, such as freezing and unfreezing of funds.
In the embodiment of the invention, after the user node successfully reserves the room on the reservation platform and pays, the hotel node and the reservation platform are divided by dividing into the intelligent contracts, so that the real-time division is realized, and the accounts receivable of the reservation platform or the hotel node is reduced. In addition, all parties can complete the transaction according to the agreed business consensus and record the transaction record into the chain deposit certificate through the block chain network, so that the manual tampering is avoided.
