[0051] In order to make the objectives, technical solutions and beneficial effects of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0052] Reference Figure 1 , which is a system architecture diagram applicable to an embodiment of the present application. The system architecture at least includes a terminal device 101, an information storage system 102, and a blockchain 103.

[0053] The terminal device 101 is installed with a target application for information storage. The application can be a pre-installed client, a web version application, a small program embedded in other applications, etc. The terminal device 101 can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto.

[0054] The information storage system 102 and the blockchain 103 are the back-end servers of the target application and provide services for the target application. The information storage system 102 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (CDN), and big data and artificial intelligence platforms.

[0055] The blockchain 103 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, Content Delivery Network (CDN), and big data and artificial intelligence platforms.

[0056] The terminal device 101 and the information storage system 102 can be directly or indirectly connected through wired or wireless communication methods, and the present application does not limit this here. The information storage system 102 and the blockchain ၁၀၃ can be directly or indirectly connected through wired or wireless communication methods, and the present application does not limit this here.

[0057] In response to the user's information storage operation, the terminal device 101 sends an information storage instruction to the information storage system 102. The information storage system 102 receives the information to be stored sent by the terminal device, preprocesses the information to be stored to obtain target information, and stores the target information in the database in the information storage system 102; sends the information to be stored to the blockchain 103 so that the blockchain 103 stores the information to be stored. Among them, before the information storage system 102 receives the storage success message returned by the blockchain 103, it responds to the query request for the information to be stored through the database; after the information storage system 102 receives the storage success message returned by the blockchain 103, it responds to the operation request for the information to be stored through the blockchain 103.

[0058] Based on Figure 1 the above system architecture diagram, an embodiment of the present application provides a process of an information storage method, as Figure 2 shown. This method is executed by Figure 1 the information storage system 102 shown as follows:

[0059] Step S201: Receive the information to be stored sent by the terminal device, preprocess the information to be stored to obtain target information, and store the target information in the database.

[0060] Specifically, the information storage system performs splitting processing on the information to be stored to obtain target information.

[0061] For example, the information to be stored is shown in Table 1, including two groups of information. The number in the first group of information is 01, the user name is Zhang San, and the affiliated department is Department 1. The number in the second group of information is 02, the user name is Li Si, and the affiliated department is Department 2.

[0062] Table 1.

[0063] Number Username Department 01 Zhang San Department 1 02 Li Si Department 2

[0064] The information storage system performs splitting processing on the information to be stored to obtain two groups of target information, as shown in Table 2 and Table 3 respectively.

[0065] Table 2.

[0066] Number Username Department 01 Zhang San Department 1

[0067] Table 3.

[0068] Number Username Department 02 Li Si Department 2

[0069] Step S202: Send the target information to the blockchain so that the blockchain stores the target information.

[0070] Specifically, the information storage system can send the target information to the database and the blockchain simultaneously; it can also send the target information to the database first and then to the blockchain; or it can send the target information to the blockchain first and then to the database.

[0071] Step S203: Determine whether a storage success message returned by the blockchain is received. If so, execute Step S205; otherwise, execute Step S204.

[0072] Step S204: Respond to the query request for the target information through the database.

[0073] Specifically, receive the query request for the target information sent by the terminal device, obtain the query information from the database, integrate the query information to obtain the target information, and send the target information to the terminal device.

[0074] For example, the query request is to query the target information corresponding to number 01. After the information storage system receives this query request, it obtains the query information corresponding to number 01 from the database, which are 01, Zhang San, and Department 1 respectively. Integrate the above query information to obtain the target information, that is, number: 01, user name: Zhang San, affiliated department: Department 1, and send this information to the terminal device.

[0075] Step S205: Respond to the operation request for the target information through the blockchain.

[0076] Specifically, after the information storage system receives the storage success message returned by the blockchain, it simultaneously deletes the target information saved in the database.

[0077] The operation request includes an addition request, a deletion request, a modification request, and a query request.

[0078] Receive the operation request for the target information sent by the terminal device, send the operation request to the blockchain so that the blockchain performs corresponding data operations on the target information to obtain a data operation result; receive the data operation result sent by the blockchain and send the data operation result to the terminal device.

[0079] For example, when the operation request is a deletion request, the information storage system receives the deletion request for the target information sent by the terminal device and sends this deletion request to the blockchain. After the blockchain performs the corresponding deletion operation on the target information, it obtains a data deletion result. The information storage system receives the data deletion result sent by the blockchain and sends this data deletion result to the terminal device.

[0080] When the operation request is a query request, the information storage system receives the query request for the target information sent by the terminal device, and sends the query request to the blockchain. After the blockchain performs the corresponding query operation on the target information, it obtains the data query result. The information storage system receives the data query result sent by the blockchain and sends the data query result to the terminal device.

[0081] In the embodiment of the present application, after the information storage system receives the information to be stored sent by the terminal device, it preprocesses the information to be stored to obtain the target information, and stores the target information in the database. The information storage system sends the target information to the blockchain so that the blockchain stores the target information. Before the information storage system receives the storage success message returned by the blockchain, it responds to the query request for the target information through the database. After receiving the storage success message returned by the blockchain, it responds to the operation request for the target information through the blockchain. In the present application, the target information is stored in the blockchain, which avoids the risk of being tampered with when the target information is stored in the database. At the same time, during the process of storing the target information in the blockchain, the database responds to the query request for the target information, which solves the problem that when the target information is stored, the target information in the blockchain cannot be accessed, thus affecting the business processing efficiency.

[0082] Optionally, since there may be a risk of tampering with the target information stored in the database, before step S205 above, the information storage system needs to determine whether the target information stored in the database is consistent with the target information stored in the blockchain. If they are consistent, step S205 is executed; otherwise, an alarm message is sent to the terminal device.

[0083] Optionally, in step S203 above, if the information storage system receives a storage failure message returned by the blockchain, it sends a storage failure message to the terminal device.

[0084] To better explain the embodiments of the present application, the following takes a specific embodiment scenario as an example to introduce the process of an information storage method provided by the embodiments of the present application, as Figure 3 shown:

[0085] Step S301, receive the information to be stored sent by the terminal device, preprocess the information to be stored to obtain the target information, and store the target information in the database.

[0086] Step S302, send the target information to the blockchain so that the blockchain stores the target information.

[0087] Step S303, determine whether a storage success message returned by the blockchain is received. If so, execute step S307; otherwise, execute step S304.

[0088] Step S304: Determine whether a storage failure message returned by the blockchain is received. If so, execute Step S305; otherwise, execute Step S306.

[0089] Step S305: Send a storage failure message to the terminal device.

[0090] Step S306: Receive a query request for the target information sent by the terminal device, obtain query information from the database, integrate the query information to obtain the target information, and send the target information to the terminal device.

[0091] Step S307: Determine whether the target information saved in the database is consistent with the target information saved in the blockchain. If so, execute Step S308; otherwise, execute Step S311.

[0092] Step S308: Delete the target information saved in the database.

[0093] Step S309: Receive an operation request for the target information sent by the terminal device, and send the operation request to the blockchain so that the blockchain performs corresponding data operations on the target information to obtain a data operation result.

[0094] Step S310: Receive the data operation result sent by the blockchain and send the data operation result to the terminal device.

[0095] Step S311: Send an alarm message to the terminal device.

[0096] In the embodiment of the present application, storing the target information in the blockchain avoids the risk of being tampered with when storing the target information in the database. At the same time, during the process of storing the target information in the blockchain, the database responds to the query request for the target information, solving the problem that when storing the target information, the target information in the blockchain cannot be accessed, thus affecting the business processing efficiency. At the same time, after the information storage system receives the storage success message returned by the blockchain, the information storage system deletes the target information saved in the database, effectively avoiding information leakage.

[0097] To better explain the embodiment of the present application, the following describes an information storage method provided by the embodiment of the present application in combination with a specific implementation scenario. This method is executed by Figure 1 the information storage system 102 therein. As Figure 4 shown, it includes a terminal device 101, an information storage system 102, and a blockchain 103. Among them, the system architecture of the information storage system 102 includes a service acquisition module 401, an access and storage service module 402, a monitoring and verification module 403, and a database 404.

[0098] The terminal device 101 sends the information to be stored to the service acquisition module 401. The service acquisition module 401 sends the information to be stored to the access service module 402. The access service module 402 preprocesses the information to be stored to obtain the target information, and stores the target information in the database 404. Meanwhile, the access service module 402 sends the target information to the blockchain 103, and the blockchain 103 stores the target information. The monitoring and verification module 403 monitors the blockchain. Before the monitoring and verification module 403 receives the storage success message returned by the blockchain 103, it responds to the query request for the target information through the database 404; after the monitoring and verification module 403 receives the storage success message returned by the blockchain 103, it responds to the operation request for the target information through the blockchain 103.
