Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a schematic diagram of a system architecture of information processing according to an embodiment of the present application. After booking the hotel room, the business server feeds back the booking result to the booking terminal, if booking is successful, the business server saves the room booking information and the user information of the booking user and sends the room booking information and the user information to a blockchain node in a blockchain link point system, and the blockchain node links the room booking information and the user information. When the request user arrives at the hotel, the management device sends a query request to the blockchain when the request terminal is used for requesting to check in on the management device, after the room reservation information and the user information fed back by the blockchain are obtained, the management device judges whether the reservation user and the request user are the same user or not, further judges whether the request user can check in the hotel room based on the room reservation information, if the request user can check in the hotel room, a corresponding room door lock is opened, and if the request user cannot check in the hotel room, a prompt message that the request terminal cannot check in is returned to the request terminal.
The subscription terminal, the request terminal, and the blockchain node may include a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID, mobile INTERNET DEVICE), and the like. The service server is a background server of a booking Application (APP), and provides hotel information for users, stores and transmits room booking information and user information of the users. The blockchain contains a series of information of hotel rooms and user information, and provides inquiry for management equipment. The management device may include an on-door authentication device for a reservation room, an authentication device for a hotel lobby, 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 application. As shown in fig. 2, the method may include:
Step S101, a management device acquires a check-in request carrying reservation check-in time sent by a request terminal, and acquires a target block from a block chain according to the check-in request; the target block is a block associated with the reserved check-in time and a target room number; the target room number is the room number requested by the check-in request.
Specifically, when the requesting user arrives at the hotel and requests to check in, 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 acquire 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, identity document or other document detailed information of the requesting user, and the like. The management equipment records a request receiving time stamp (namely the time of receiving the check-in request), a target room number and a terminal signature, and sends a query request carrying the reservation check-in time and the target room number to the blockchain node according to the information carried by the check-in request; the blockchain node obtains a target block based on the reserved time of stay and the target room number. The above-mentioned manner of generating the check-in request is not limited, and the request terminal may be used by the requesting user to scan the two-dimensional code on the management device, where the page of the requesting terminal is converted into a page for filling in the hotel target room number and booking the check-in time, and the request user fills in the page and submits the page to the management device, and the management device sends the query request to the blockchain node according to the information contained in the page; the manner of generating the check-in request may be a serial number or face recognition, and specific processes are not repeated here.
Step S102, the public key of the user and the user check-in reservation information in the target block are acquired.
Specifically, the user public key and the user check-in reservation information are generated by the reservation user and the reservation 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 the check-in time, the target room number, the check-out time, and the like, the user information may include a terminal signature of the reservation terminal, identity document or other certificate details of the reservation user, and the reservation user public key (i.e., the user public key), and the like, and are transmitted to the blockchain node by the service server in fig. 1, and the blockchain node calculates the user check-in reservation information into a first hash value according to a preset hash algorithm, and generates the target blockchain with the first hash value, the user check-in reservation information, and the user public key.
And step S103, checking the terminal signature carried in the check-in request according to the public key of the user.
Specifically, please refer to fig. 3, which is a flowchart illustrating another information processing method according to an embodiment of the present application. In one aspect, the management device obtains a first hash value in the target block; on the other hand, the management device decrypts the terminal signature by adopting the user public key in the target block to obtain a second hash value, wherein the terminal signature is obtained by signing the second hash value (for distinguishing whether the terminal signature is legal) of the request terminal by utilizing the private key of the request user, and the second hash value is calculated and generated based on the reservation 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 legal signature, and also indicating that the reservation information of the request terminal is consistent with the user check-in reservation information of the reservation terminal, so that the request user can be determined to be the reservation user, namely, the terminal signature belonging to 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 further it can be determined that the requesting user and the subscribing user are not the same person because the subscription information of the requesting user and the subscribing user is different, and the generated signature is different. Of course, when the public key of the user in the target block cannot decrypt the terminal signature, it may also be determined that the requesting user and the subscribing user are not the same person, and the terminal signature cannot be decrypted because the private keys of the requesting user and the subscribing user are different.
On the one hand, the management equipment refuses the check-in request of the requesting user and returns failure prompt information to the requesting terminal under the condition that the terminal signature is an illegal signature; and on the other hand, the request receiving time stamp, the failure prompt information, the terminal signature carried in the check-in request and the target room number corresponding to the check-in request are sent to a blockchain node so that the blockchain node performs uplink processing, and the later-stage service server or management equipment can conveniently inquire.
In the case that the terminal signature is a legal signature, the subsequent processing refers to step S104.
And step S104, if the terminal signature is verified to be a legal signature, determining the check-in authority of the request terminal for the target room number according to the user check-in reservation information.
As can be seen from step S103, the requesting user is a subscriber, in which case the management device needs to verify the living authority of the requesting user to prevent the subscriber from recording the wrong living time and entering the target room of the other subscribers on the same day.
Specifically, please refer to fig. 4, which is a flowchart illustrating another information processing method according to an embodiment of the present application. After acquiring 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 request 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 request user is determined to have check-in authority, the management equipment opens a target room door lock for the request user, otherwise, the check-in request of the request user is refused and the request user is prompted to not check in time.
Fig. 5 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:
