[0087] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

"And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple. In this application, the terms "first", "second", etc. are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. The association or associated storage of A and B means that B can be obtained based on A, or A can be obtained based on B.

[0089] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar contents will not be repeatedly described in different embodiments.

[0090] Figure 1 For the application scenario diagram provided by the embodiment of the present application, see Figure 1 When a visiting user makes an appointment for a visit, the application server 11 receives the basic information of the visiting user from the appointment terminal 12 and generates a first appointment code based on the basic information. The application server 11 sends the basic information and the first appointment code to the blockchain node in the blockchain system 13, and the blockchain node generates a first block based on the basic information and the first appointment code.

[0091] When a visiting user visits, the application server 11 receives the registration information of the visiting user from the registration terminal 14, and sends the registration information to the blockchain node in the blockchain system 13, and the blockchain node generates a second block according to the registration information; the application server 11 also receives the second appointment code of the visiting user from the code scanning terminal 15, and verifies whether the second appointment code is the same as the first appointment code.

[0092] The application server 11 also sends the basic information, the first appointment code and the registration information to the database server 16 for storage.

[0093] The above method ensures that the basic information of the visiting user, the first appointment code and the registration information are all stored in the blockchain node and will not be lost or tampered with.

[0094] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar contents will not be repeatedly described in different embodiments.

[0095] The information processing method of the present application involves the information processing method of the visiting user in the reservation stage and the information processing method in the visiting stage.

[0096] First, combine Figure 2 and Figure 3 The information processing method at the reservation stage in this embodiment will be described.

[0097] Figure 2 Signaling interaction of the information processing method provided in the embodiment of the present application Figure 1 , see Figure 2 , the method of this embodiment includes:

[0098] Step S201: The reservation terminal obtains basic information of the visiting user.

[0099] Specifically, the basic information includes at least one of the following: name, mobile phone number, ID card number, visit date, etc.

[0100] The visiting user informs the visited user of the basic information of the visiting user before the visit, and the visited user inputs the basic information of the visiting user through the user interface of the reservation terminal, and the reservation terminal obtains the basic information of the visiting user. Among them, the reservation terminal can be a terminal installed with reservation management software.

[0101] Step S202: The reservation terminal sends the basic information to an application server.

[0102] Specifically, after the reservation terminal obtains the basic information of the visiting user, it sends the basic information to the application server.

[0103] Step S203: The application server generates a first reservation code according to the basic information.

[0104] Specifically, the application server receives the basic information and generates a first reservation code according to the basic information; the method of generating a reservation code according to the basic information refers to the method in the prior art, which will not be repeated in this embodiment. The first reservation code can be in any of the following forms: a form of multiple characters, a barcode, a QR code, etc.

[0105] Step S204: The application server sends the basic information and the first reservation code to a blockchain node.

[0106] Specifically, in one embodiment, after the application server generates the first reservation code, it sends the basic information and the first reservation code to the blockchain node in the blockchain system.

[0107] In another embodiment, after receiving the basic information, the application server may send the basic information to the blockchain node in the blockchain system, and after generating the first reservation code, send the first reservation code to the blockchain node.

[0108] The blockchain system in this embodiment may be a private chain system, and the blockchain node is a node in the private chain system that can generate blocks. In a public chain system, each node can generate blocks, so in the public chain system, the blockchain node is the node that currently generates blocks the fastest.

[0109] It can be understood that the blockchain system includes multiple nodes. In addition to sending the basic information and the first reservation code to the blockchain node, the application server also sends them to other nodes in the multiple nodes of the blockchain system other than the blockchain node. The subsequent embodiments are the same and will not be repeated here.

[0110] Step S205: The application server sends the basic information and the first reservation code to a database server.

[0111] Specifically, the application server also sends the basic information and the first appointment code to the database server. After receiving the basic information and the first appointment code, the database server stores the basic information and the first appointment code in association.

[0112] Step S206: The blockchain node generates a first block according to the basic information and the first reservation code.

[0113] Specifically, the blockchain node generates a first block according to the basic information and the first reservation code, and broadcasts the block to other nodes.

[0114] Step S207: The blockchain node sends the first hash value of the first block to the application server.

[0115] Step S208: The application server sends the first hash value to the database server;

[0116] Specifically, after receiving the first hash value, the application server sends the first hash value to the database server. The first hash value is used to identify the first block, and other users can later obtain the information included in the first block through the first hash value.

[0117] Step S209: The database server stores the basic information, the first reservation code and the first hash value in association with each other.

[0118] Specifically, after receiving the basic information, the first appointment code and the first Hash value, the database server stores the basic information, the first appointment code and the first Hash value in association with each other.

[0119] Since the database service stores the basic information, the first reservation code and the first hash value in association, when other users want to view the basic information and the first reservation code of the visiting user stored in the blockchain node, the application server can obtain the first hash value through the identifier of the visiting user input by other users in the backtracking terminal (which can be the same terminal as the reservation terminal or the registration terminal, or a different terminal), because the basic information contains the identifier of the visiting user, and the first hash value is stored in association with the basic information in the database server. After obtaining the first hash value, the application server can send a viewing request carrying the first hash value to the blockchain node. After receiving the viewing request, the blockchain node sends the basic information and the first reservation code included in the first block indicated by the first hash value to the application server. The application server sends the basic information and the first reservation code included in the first block to the backtracking terminal for display, thereby achieving the purpose of viewing the basic information and the first reservation code of the visiting user stored in the blockchain node.

[0120] In addition, after the application server obtains the first hash value, it can send the first hash value to the backtracking terminal, and the backtracking terminal sends a viewing request carrying the first hash value to the blockchain node. After receiving the viewing request, the blockchain node sends the basic information included in the first block indicated by the first hash value and the first appointment code to the backtracking terminal for display.

[0121] In this embodiment, the basic information and reservation code of the visiting user are stored in the database server as well as in the blockchain node of the blockchain system. The basic information and reservation code stored in the blockchain system are generated into blocks and will not be lost. The first hash value of the generated block is associated with the basic information and reservation code of the visiting user in the database server and stored, so that other users can trace back the basic information and reservation code of the visiting user.

[0122] It should be understood that the sequence numbers of the above processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0123] In order to determine whether the basic information of the visiting user and the first reservation code generated based on the basic information have been tampered with during the process of being sent to the blockchain node, this embodiment is further improved on the basis of the previous embodiment. Figure 3 Signaling interaction of the information processing method provided in the embodiment of the present application Figure 2 , see Figure 3 The method of this embodiment includes:

[0124] Step S301: The reservation terminal obtains basic information of the visiting user.

[0125] The specific implementation refers to step S201 in the previous embodiment and will not be described again here.

[0126] Step S302: The reservation terminal sends the basic information to an application server.

[0127] The specific implementation refers to step S202 in the previous embodiment and will not be described in detail here.

[0128] Step S303: the application server generates a first reservation code according to the basic information;

[0129] The specific implementation refers to step S203 in the previous embodiment, which will not be described again here.

[0130] Step S304: the application server generates a second hash value according to the basic information and the first reservation code;

[0131] Specifically, the application server generates a second hash value according to the basic information and the first reservation code.

[0132] Step S305: The application server sends the basic information, the first reservation code and the second hash value to the blockchain node;

[0133] In addition to sending the basic information and the first reservation code to the blockchain node, the application server also sends the second hash value to the blockchain node.

[0134] The meaning of the blockchain node in this embodiment is the same as the meaning of the blockchain node in the previous embodiment.

[0135] Step S306: The application server sends the basic information and the first reservation code to a database server.

[0136] Specifically, the application server may send the second hash value to the database server in addition to sending the basic information and the first reservation code to the database server.

[0137] Step S307: the blockchain node generates a first block according to the basic information, the first reservation code and the second hash value;

[0138] If the first block includes the second hash value, a fifth hash value can be regenerated according to the basic information and the first reservation code after obtaining the basic information and the first reservation code in the first block. If the fifth hash value and the second hash value are the same, it means that the basic information, the first reservation code and the second hash value have not been tampered with in the process of sending them to the blockchain node; if the fifth hash value and the second hash value are different, it means that the basic information, the first reservation code and the second hash value have been tampered with in the process of sending them to the blockchain node, or the first reservation code has been tampered with, or the second hash value has been tampered with.

[0139] Step S308: The blockchain node sends the first hash value of the first block to the application server;

[0140] The specific implementation refers to step S307 in the previous embodiment, which will not be described in detail here.

[0141] Step S309: The application server sends the first hash value to the database server;

[0142] The specific implementation refers to step S308 in the previous embodiment, which will not be described again here.

[0143] Step S310: The database server stores the basic information, the first reservation code and the first hash value in association with each other.

[0144] If the application server also sends the second hash value to the database server, the database server stores the basic information, the first reservation code, the first hash value and the second hash value in association with each other.

[0145] In this embodiment, the application server also generates a second hash value of the basic information of the visiting user and the first appointment code. When other users obtain the basic information of the visiting user and the first appointment code in the first block, it can determine whether the basic information of the visiting user, the first appointment code and the second hash value have been tampered with in the process of sending them to the blockchain node, thereby ensuring that other users can trace the correct basic information of the visiting user and the first appointment code.

[0146] It should be understood that the sequence numbers of the above processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0147] Secondly, based on the above embodiments, combined with Figure 4 and Figure 5 The information processing method in the visit phase in this embodiment is described.

[0148] Figure 4 Signaling interaction of the information processing method provided in the embodiment of the present application Figure 3 , see Figure 4 , the method of this embodiment includes:

[0149] Step S401: The scanning terminal obtains the second appointment code of the visiting user.

[0150] Specifically, when the visiting user arrives, he / she presents his / her second appointment code. It is understandable that if the visiting user is a user who has made an appointment in the previous embodiment, and the visiting user presents the first appointment code obtained during the appointment stage, the second appointment code is the same as the first appointment code.

[0151] The code scanning terminal scans the second appointment code to obtain the second appointment code.

[0152] Step S402: The code scanning terminal sends the second reservation code to the application server.

[0153] Specifically, after the code scanning terminal obtains the second reservation code, it sends the second reservation code to the application server.

[0154] Step S403: The application server verifies the second reservation code.

[0155] Specifically, if the visiting user has made an appointment, the database server stores a first appointment code obtained by the visiting user during the appointment stage, and the application server obtains the first appointment code from the database server. If the second appointment code is the same as the first appointment code, it is determined that the second appointment code has been verified. If they are not the same or the database server does not store the first appointment code obtained by the visiting user during the appointment stage, it is determined that the second appointment code has failed to be verified.

[0156] After the application server determines that the second reservation code has been verified, it may send a message indicating successful verification to the code scanning terminal.

[0157] Step S404: The registration terminal obtains the registration information of the visiting user.

[0158] Specifically, after the reservation code presented by the visiting user is successfully verified, the visiting user's registration information can be input through the user interface of the registration terminal, and the registration terminal obtains the registration information.

[0159] The registration information may include at least one of the following: name, personal identity, relationship with the visitee, reason for visit, date of visit, etc.

[0160] Step S405: The registration terminal sends the registration information to the application server.

[0161] Specifically, after the registration terminal obtains the registration information, it sends the registration information to the application server.

[0162] Step S406: The application server verifies the registration information.

[0163] Specifically, the specific method for the application server to verify the registration information may be as follows:

[0164] The application server sends a first request to the database server, where the first request is used to instruct the database server to obtain basic information corresponding to a first identifier. The first request includes the first identifier, which is the identifier of the visiting user included in the registration information, such as the user's name.

[0165] The database server inquires whether basic information including the identifier is stored, and sends a first response to the application server, which receives the first response; if basic information including the first identifier is stored in the database server, the first response includes the basic information, and the application server compares the registration information with the basic information. If the registration information and the basic information have the same content, the application server determines that the registration information has been verified; if basic information including the first identifier is not stored in the database server, the first response does not include the basic information, and at this time, the application server determines that the registration information has failed to be verified.

[0166] Among them, the contents of the items that are the same as the registration information and the basic information are the same, which means that if the registration information includes the "item" - ID card number, the basic information also includes the "item" - ID card number, the content of the ID card number item in the registration information is 1234567890, and the content of the ID card number item in the basic information is also 1234567890.

[0167] After the application server determines that the registration information has been verified, it may send a message indicating successful verification to the registration terminal.

[0168] Step S407: If the second reservation code and the registration information are verified, the application server sends the registration information to the blockchain node.

[0169] Specifically, after the second appointment code and the registration information are verified, the application server sends the registration information to the blockchain node.

[0170] The meaning of the blockchain node in this embodiment is the same as the meaning of the blockchain node in the above embodiments.

[0171] Step S408: If the second reservation code and the registration information are verified, the registration information is sent to the database server.

[0172] Specifically, after the second appointment code and the registration information are verified, the application server also sends the registration information to the blockchain node.

[0173] Step S409: the blockchain node generates a second block according to the registration information;

[0174] Specifically, the blockchain node generates a second block according to the registration information, and broadcasts the second block to other nodes.

[0175] Step S410: The blockchain node sends the third hash value of the second block to the application server.

[0176] Specifically, the third hash value is used to identify the second block, and other users can later obtain the information included in the second block through the third hash value.

[0177] Step S411: The application server sends the third hash value to the database server.

[0178] Specifically, after receiving the third Hash value, the application server sends the third Hash value to the database server.

[0179] Step S412: The database server associates and stores the registration information with the third Hash value.

[0180] Specifically, after receiving the registration information and the third Hash value, the database server stores the registration information and the third Hash value in association with each other.

[0181] Since the database service associates and stores the registration information with the third hash value, when other users subsequently want to view the registration information of the visiting user stored in the blockchain node, the application server can obtain the third hash value through the identifier of the visiting user entered by other users in the backtracking terminal (which can be the same terminal as the reservation terminal or the registration terminal, or a different terminal), because the registration information contains the identifier of the visiting user, and the third hash value is associated and stored with the registration information in the database server. After obtaining the third hash value, the application server can send a viewing request carrying the third hash value to the blockchain node. After receiving the viewing request, the blockchain node sends the registration information included in the second block indicated by the third hash value to the application server. The application server sends the registration information included in the second block to the backtracking terminal for display, thereby achieving the purpose of viewing the registration information of the visiting user stored in the blockchain node.

[0182] In addition, after the application server obtains the third hash value, it can send the third hash value to the backtracking terminal, and the backtracking terminal sends a viewing request carrying the third hash value to the blockchain node. After receiving the viewing request, the blockchain node sends the registration information included in the second block indicated by the third hash value to the backtracking terminal for display.

[0183] In this embodiment, the registration information of visiting users is stored not only in the database server, but also in each node of the blockchain system. The registration information stored in the blockchain system is generated into blocks and will not be lost, so that other users can trace the user's registration information.

[0184] It should be understood that the sequence numbers of the above processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0185] In order to determine whether the registration information of the visiting user has been tampered with during the process of being sent to the blockchain node, this embodiment is further improved on the basis of the previous embodiment. Figure 5 Signaling interaction of the information processing method provided in the embodiment of the present application Figure 4 , see Figure 5 , the method of this embodiment includes:

[0186] Step S501: The scanning terminal obtains the second appointment code of the visiting user.

[0187] Step S502: The code scanning terminal sends the second reservation code to the application server.

[0188] Step S503: the application server verifies the second reservation code;

[0189] Step S504: The registration terminal obtains the registration information of the visiting user.

[0190] Step S505: The registration terminal sends the registration information to an application server.

[0191] Step S506: The application server verifies the registration information.

[0192] The specific implementation of steps S501 to S506 refers to the description of steps S401 to S406 in the previous embodiment, which will not be repeated here.

[0193] Step S507: The application server generates a fourth Hash value according to the registration information.

[0194] Specifically, the application server generates a fourth hash value according to the registration information.

[0195] If the second block includes the fourth hash value, a sixth hash value can be regenerated according to the registration information after obtaining the registration information in the second block. If the sixth hash value is the same as the fourth hash value, it means that neither the registration information nor the fourth hash value has been tampered with in the process of sending the registration information and the fourth hash value to the blockchain system; if the sixth hash value is different from the fourth hash value, it means that the registration information has been tampered with or the fourth hash value has been tampered with in the process of sending the registration information and the fourth hash value to the blockchain node.

[0196] Step S508: If the second reservation code and the registration information are verified, the application server sends the registration information and the fourth hash value to the blockchain node.

[0197] The meaning of the blockchain node in this embodiment is the same as the meaning of the blockchain node in the above embodiments.

[0198] Step S509: If the second reservation code and the registration information are verified, the application server also sends the registration information to the database server.

[0199] Specifically, the application server may also send the fourth Hash value to the database server.

[0200] Step S510: The blockchain node generates a second block according to the registration information and the fourth hash value.

[0201] Specifically, the blockchain node generates a second block according to the registration information and the fourth hash value, and broadcasts the second block to other nodes.

[0202] Step S511: The blockchain node sends the third hash value of the second block to the application server;

[0203] Step S512: The application server sends the third hash value to the database server.

[0204] Step S513: The database server associates and stores the registration information with the third Hash value.

[0205] The specific implementation of steps S511 to S513 refers to the description of steps S410 to S412 in the previous embodiment, which will not be repeated here.

[0206] If the application server also sends the fourth Hash value to the database server, the database server stores the registration information, the third Hash value, and the fourth Hash value in association with each other.

[0207] In this embodiment, the application server also generates a fourth hash value of the visiting user's registration information. When other users obtain the visiting user's registration information included in the second block, it can determine whether the visiting user's registration information and the fourth hash value have been tampered with in the process of sending the visiting user's registration information to the blockchain node, thereby ensuring that other users can trace the correct registration information of the visiting user.

[0208] It should be understood that the sequence numbers of the above processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
