Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic diagram of a system architecture for information processing according to an embodiment of the present disclosure. The booking user checks hotel information on a booking application by using the booking terminal, after the booking user books a hotel room, the service server feeds back a booking result to the booking terminal, if the booking is successful, the service server stores the room booking information and the user information of the booking user, and sends the room booking information and the user information to a block link point in a block link point system, and the block link point links the room booking information and the user information. When a request user arrives at the hotel and requests to check in on the management equipment by using the request terminal, the management equipment sends a query request to the block chain, after the room reservation information and the user information fed back by the block chain are obtained, the management equipment judges whether the reservation user and the request user are the same user, then judges whether the request user can check in the hotel room based on the room reservation information, if so, a door lock of the corresponding room is opened, and if not, prompt information that the request user cannot check in is returned to the request terminal.
The reservation terminal, the request terminal, and the block link point may include a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), and the like. The service server is a background server of a subscription Application (APP) and provides hotel information for the user, and stores and transmits room subscription information and user information of the user. The block chain comprises a series of information of hotel rooms and user information, and provides query for the management equipment. The management device may include an on-door authentication device for a reserved room, an authentication device for a hotel front desk, or an authentication device in a hotel lobby.
Fig. 2 is a schematic flow chart of an information processing method according to an embodiment of the present application. As shown in fig. 2, the method may include:
step S101, a management device acquires a check-in request which is sent by a request terminal and carries a reserved check-in time, and acquires a target block from a block chain according to the check-in request; the target block is a block associated with the reservation check-in time and a target house number; the target house number is the house number requested by the check-in request.
Specifically, when the requesting user requests to check in after arriving at the hotel, the requesting user may use the requesting terminal to send a check-in request to the management device, for example, the requesting terminal displays a two-dimensional code to the management device, the management device may obtain room reservation information and user information of the requesting user by scanning the two-dimensional code, the room reservation information may include reservation check-in time, target room number, reservation check-out time, and the like, and the user information may include a terminal signature of the requesting terminal, an identity certificate of the requesting user, or detailed information of other certificates, and the like. The management equipment records a request receiving timestamp (namely the time of receiving the check-in request), a target house number and a terminal signature, and sends an inquiry request carrying the reserved check-in time and the target house number to the block link point according to the information carried by the check-in request; the block link point obtains a target block according to the reserved check-in time and the target house number. The mode of generating the check-in request is not limited, and can be that a request user uses a request terminal to scan a two-dimensional code on the management equipment, a request terminal page is converted into a page for filling in a hotel target room number and reserving check-in time, the request user writes the page and submits the page to the management equipment, and the management equipment sends a query request to the block link point according to information contained in the page; the mode of generating the check-in request may also be a string of serial numbers or face recognition, and the specific process is not described in detail here.
Step S102, obtaining the user public key and the user check-in reservation information in the target block.
Specifically, the user public key and the user check-in reservation information are generated by the subscriber and the subscriber terminal in fig. 1, the user check-in reservation information includes the room reservation information and the user information in fig. 1, the room reservation information may include a reservation check-in time, a target house number, a reservation check-out time, and the like, the user information may include a terminal signature of the subscriber terminal, an identity certificate or other certificate details of the subscriber, and a subscriber public key (i.e., a user public key), and the like, and is transmitted to the block link node by the service server in fig. 1, the block link node calculates the user check-in reservation information into a first hash value according to a preset hash algorithm, and generates a target block from the first hash value, the user check-in reservation information, and the user public key so as to be linked.
And step S103, checking the terminal signature carried in the check-in request according to the user public key.
Specifically, please refer to fig. 3, which is a flowchart illustrating another information processing method according to an embodiment of the present application. On one hand, the management equipment acquires a first hash value in the target block; on the other hand, the management device decrypts the terminal signature by using the user public key in the target block to obtain a second hash value, wherein the terminal signature is obtained by signing a second hash value (for distinguishing whether the terminal signature is legal) of the request terminal by using the private key of the request user, and the second hash value is calculated and generated based on the subscription information of the request terminal; comparing the first hash value with the second hash value, if the first hash value is the same as the second hash value, determining that the terminal signature is a legal signature, and also indicating that the subscription information of the request terminal is consistent with the subscription information of the subscription terminal for the user to check in, thereby determining that the request user is the subscription user, namely that the terminal signature belonging to the legal signature is obtained by encrypting the first hash value by the request terminal based on a user private key corresponding to the user public key; if the first hash value is different from the second hash value, the terminal signature can be determined to be an illegal signature, and then the requesting user and the subscribing user can be determined not to be the same person, because the subscribing information of the requesting user and the subscribing user is different, the generated signatures are different. Of course, when the terminal signature cannot be decrypted by using the user public key in the target block, it may be determined that the requesting user and the subscribing user are not the same person, because the private keys of the requesting user and the subscribing user are different, so that the terminal signature cannot be decrypted.
Under the condition that the terminal signature is an illegal signature, on one hand, the management equipment refuses the check-in request of the user and returns failure prompt information to the request terminal; on the other hand, the request receiving timestamp, the failure prompt message, the terminal signature carried in the check-in request and the target house number corresponding to the check-in request are sent to a block chain node, so that the block chain node performs uplink processing, and a later service server or management equipment is convenient to inquire.
In the case where the terminal signature is a valid signature, the subsequent processing refers to step S104.
And step S104, if the signature of the terminal is verified to be a legal signature, determining the check-in authority of the request terminal aiming at the target house number according to the user check-in reservation information.
As shown in step S103, the requesting user is a subscribing user, in which case the management device needs to verify the check-in authority of the requesting user, so as to prevent the subscribing user from mistaking the subscription check-in time and checking in the target room of the current day subscribed by other subscribing users.
Specifically, please refer to fig. 4, which is a flowchart illustrating another information processing method according to an embodiment of the present application. After obtaining the user check-in reservation information in the target block, the management equipment confirms the check-in time and the check-out time of the requesting user, and determines the check-in time range of the requesting user according to the check-in time and the check-out time; if the requesting user requests to check in within the user check-in time range, namely the request receiving timestamp is within the user check-in time range, the requesting user is determined to have the check-in authority, the management device opens the target room door lock for the requesting user, and otherwise, the request of checking in of the requesting user is refused and the requesting user is prompted to be short of the check-in time.
Please refer to fig. 5, which is a timing diagram of an information processing method according to an embodiment of the present application. As shown in fig. 5, the method may include:
s201, receiving user check-in reservation information and a user public key.
Specifically, any block chain node receives user check-in reservation information and a user public key sent by a service server, the user check-in reservation information is generated by reservation user information and hotel room information reserved by the user, the user public key is generated by a user private key, the block chain node is open, all persons and a server can obtain the user public key, the user private key is generated by a user terminal and is a personal private of the user, other persons cannot steal the user private key, and the user public key cannot deduce the user private key.
S202, generating a target block.
Specifically, after receiving the user check-in reservation information and the user public key, the block link node checks the user check-in reservation information and the user public key, stores the user check-in reservation information and the user public key after the check, calculates the user check-in reservation information into a first hash value according to a preset hash algorithm, and generates a target block by using the first hash value, the user check-in reservation information and the user public key.
S203, adding the data into the block chain.
Specifically, the block link point sends the target block to other nodes on the block chain, the other nodes check the target block, and the target block is added to the block chain after the check is completed.
The above steps S201 to S203 can refer to fig. 6a together, which is a schematic diagram of a data uplink scenario provided in the embodiment of the present application. In fig. 6a, a subscriber uses a reservation terminal to view hotel information on a reservation application, and after the reservation of a hotel room by the subscriber is successful, a service server (which is a background server of the reservation application) stores the room reservation information and the user information of the subscriber and transmits the room reservation information and the user information to a block chain node, and the block chain node links the room reservation information and the user information. The data to be uplink, i.e., the room subscription information and the user information in fig. 6a, may include the user living subscription information, the user public key, the target house number and the first hash value corresponding to the user living subscription information described in the steps S201 to S202, and the data to be uplink is added to the target block 1004 in the block chain 100.
S204, a check-in request.
Specifically, the requesting user uses the requesting terminal to send a check-in request to the management device, and refers to step S101 in fig. 2 together with a manner of generating the check-in request, where the check-in request carries the reserved check-in time and the target house number.
And S205, inquiring the request.
Specifically, according to the check-in request, the management device sends a query request to be carried with the reserved check-in time and the target house number to the block link node.

Specifically, according to the reserved check-in time and the target house number carried by the query request, the management device acquires the target block on the block link point.
S207, obtaining the user check-in reservation information and the user public key.
Specifically, after the target block fed back by the block chain is obtained, the management device obtains the user check-in reservation information and the user public key from the target block.
S208, a first hash value and a second hash value are obtained.
Specifically, the management device obtains a first hash value from the target block, and verifies a terminal signature carried in a check-in request sent by the request terminal by using the user public key to obtain a second hash value.
S209, determine whether the terminal signature is legal.
Specifically, the management device determines whether the terminal signature is legal according to whether the first hash value is the same as the second hash value, and if the terminal signature is illegal, executes step S210-step S212; if the terminal signature is a valid signature, step S213 and the following steps are performed.
