Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application:

Fig. 1 schematically shows the flow of a blockchain-based APP message sharing method in an embodiment of the present application. As shown in Fig. 1, a blockchain-based APP message sharing method provided in this embodiment is applied to electronic devices such as computer systems/servers. The APP message sharing method includes the following steps:

Step S10, construct a blockchain network;

Step S20: Apply for a one-to-one corresponding area to each APP in the blockchain network, where each area forms a message chain for sharing messages of multiple APPs in the blockchain network;

In step S30, the messages of each APP are sent to the corresponding area, and the messages in each area are shared with each other in the message chain through the encryption technology of the blockchain.

In this application, multiple APPs may be multiple APPs belonging to business companies of different groups that need to share messages, but are not limited to this. It can also be the APP of multiple business departments under the same group, which forms a shared message chain within the group, which facilitates the query of various messages and improves the user experience. More preferably, the multiple APPs may be APPs of multiple business departments related to related or the same business under the same group, for example, APPs of multiple business departments related to financial business under the same group. In this application, the messages of each APP sent can include: user personal identity information, user transaction information, product marketing information and product change information, system updates and reminders and other announcement information. Among them, the construction of the blockchain network and the application of the message chain (that is, the application of each area that constitutes the message chain) are completed through node servers corresponding to multiple APPs for message sharing, and the node servers include those located in different APPs. Server and operating system.

This embodiment makes full use of the features of blockchain, such as decentralization, traceability of information, and shared ledger, to construct a blockchain network of APP messages. It is based on the advantages of blockchain technology such as encryption, non-tampering, equal rights, and co-construction. The block chain forms a shared message chain composed of multiple areas corresponding to the APP one-to-one, and then sends the messages generated in multiple APPs that require message sharing to the corresponding area to achieve multiple APPs. The comprehensive data sharing of messages, and the message content on the message chain link cannot be tampered with, which ensures the safety of data transmission, improves the reliability of message storage, and facilitates subsequent various APPs to query various messages. Stable and quick sharing of messages between two APPs.

In an optional embodiment, the step of uploading each APP message to the corresponding area in step S30, as shown in FIG. 3, specifically includes the following steps:

In step S31, before the message is sent, a unified security specification for the message sent by the APP is formulated. The security specification can be regulated from the dimensions of smart contracts, consensus mechanisms, encryption technology, authority management, etc., thereby enhancing the credibility of the blockchain and improving the reliability of message storage. Among them, the smart contract can formulate security specifications for messages sent by each APP. The bottom layer of the blockchain is cryptography. Cryptography is divided into symmetric encryption and asymmetric encryption. The encryption technology in this embodiment can use symmetric encryption or asymmetric encryption, so that APP is encrypted and sent to APP according to the encryption method used. At the same time, through the encryption technology of the blockchain, the messages sent to the region from each APP are shared in the message chain. The encryption technology is to encrypt and upload according to the requirements of the blockchain, and the decryption is also implemented in the internal algorithm of the blockchain.

Step S32, then, formulate a unified standard format for sending messages on the APP. Among them, the standard format refers to the order of uploading each element in each APP message, namely, user name, time, product number, product quantity, transaction amount, currency type (RMB/other), number of transactions, transaction type (investment /Consumption/Loan/Receipt/Debit/Expenditure/Others) and other elements are sorted in the specified order, and then sent. For example, the APP message sent in a standard format may be: User A has a loan of RMB 10000, and User B buys a piece of product No. 1, etc.

Step S33: Next, according to the unified security specifications and standard format formulated in the above steps, the messages of each APP are sent to the corresponding area. Among them, the messages of each APP are sent in real time, and the information in the message chain is automatically updated in synchronization to ensure that the information in subsequent queries is up to date, thereby improving user experience.

It should be understood that the size of the sequence numbers of step S31 and step S32 in the foregoing embodiment does 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 the implementation process of the embodiment of the application. Any restrictions.

For example, the apps of two business departments involved in financial services under the same group, namely the first APP and the second APP, respectively correspond to the first area and the second area in the message chain; the first APP assigns user C The generated message is encrypted and sent according to the standard format. The sequence of sending each element of the message in the standard format is: user name, transaction type, currency type and transaction amount. For example, the first APP sends "User C loan RMB 90,000 "To the first area, at this time, the sent message is shared in the message chain through the encryption technology of the blockchain to achieve mutual trust and sharing, and then the second APP can directly obtain the information of user C in the message chain, without having to contact the first Steps such as communication and risk assessment with an APP.

The blockchain-based APP message sharing method of this embodiment formulates a unified security specification for sending messages and a unified standard format for sending messages, so that each APP sends messages to each area in accordance with a unified security specification and standard format. In the shared message chain, mutual trust sharing is realized. Among them, all the message data sent is encrypted, and the data sharing process is also encrypted, thereby ensuring the security of data transmission and sharing; thus avoiding the existing In technology, messages between multiple apps are isolated and not interoperable. There is user identity verification. When sensitive information is transmitted, two-to-two transmission compliance communication is required. After layer-by-layer compliance assessment risk, the problem can be connected. Among them, Compliance means that business activities such as content transmission between multiple apps are consistent with laws, rules, and guidelines. That is to say, the APP message sharing method of this application is based on blockchain technology. Multiple APP sharing parties only need to comply with the security regulations once, and after the compliance is approved, they can send messages to the shared message chain of the blockchain. Moreover, the message content is mutually trusted and cannot be tampered with, which facilitates the subsequent inquiry of various messages and solves the problem of sensitive information landing (that is, if each APP message in the prior art needs to be shared, it needs to be transmitted to a physical platform for centralized management), and the transmission is insecure And other issues.

In an optional embodiment, in the blockchain-based APP message sharing method, after the step of mutual trust sharing in the message chain through the encryption technology of the blockchain, the messages in each area further include step S40, from In the message chain, message query is performed according to the query request and the obtained messages are summarized and displayed. The steps of performing message query from the message chain according to the query request and summarizing and displaying the obtained messages, as shown in Figure 4, specifically include the following steps:

Step S41, verify whether the query request satisfies the access authority; wherein, the access authority is also formulated when a unified APP message security specification is formulated, and the smart contract, as the manager of the shared message chain, is responsible for verifying the access authority of APP messages .

Step S42: If the access authority is not satisfied, the verification is not passed, and the query request is rejected.

In step S43, if the access authority is satisfied, the verification is passed, and the query request is responded to, the message to be queried is obtained from the message chain, and the obtained message is summarized and displayed. Preferably, the content displayed in summary may be one or more of the messages generated by the same user under multiple APPs, the messages generated by the same product under multiple APPs, and the announcement messages generated under multiple APPs. This makes it easy for each APP to accurately evaluate the comprehensive situation of the same customer or the same product.

The blockchain-based APP message sharing method of this embodiment can directly obtain various messages generated and sent from the APP of each business department from the shared message chain, for example, the first APP and the second APP involved in financial services under the same group , Corresponding to the first area and the second area, the first APP sent a piece of customer C’s transfer transaction information, and the second APP can query in real time on the unified shared message chain to obtain the customer C’s on the first APP This move message sent to the blockchain, and the content of the obtained message trusts each other. That is, the APP message sharing method in this embodiment facilitates the query of various messages of multiple APPs, and avoids the problem of users downloading multiple APPs to view one by one. With this application, users can download one APP to query their Messages generated in an APP (APP for message sharing) realize one-stop business service for APP users and improve the user experience of APP.

Preferably, the blockchain-based APP message sharing method includes step S44 while performing the summary display step in step S43, and recommends products according to the query request and the portrait of all the information in the message chain. Specifically:

(1) Collect user's basic data from the message chain, and conduct behavior modeling through technical means based on the user's basic data. The basic data is data summarized by all the information of the user in each APP, such as network behavior data, in-service behavior data, user content preference data, user transaction data, and so on. The technical means include text mining, natural language processing, machine learning, prediction algorithms, clustering algorithms, etc.

(2) Construct a portrait through behavior modeling, and output a series of user tags. Each user tag can form a set. The set of tags can express the characteristics of the user. For example, user tags can be basic attributes, purchasing power, Behavior characteristics, hobbies, psychological characteristics, social networks, etc.

(3) Determine recommended products based on user query requests and user tags. For example, if the user's query request is a loan information query, it is determined based on the user tag that the user has financial needs and short-term consumption intentions, and the user's hobby is a car, then when product recommendations, car mortgage loans and other products can be recommended for the user .

(4) After the recommended product is determined, the recommended product is recommended and displayed in the descending order of matching degree with the user's label. Wherein, the recommended product may be displayed as the content of the recommended product or a related link address, for example, as a link address of a car mortgage loan webpage.

The foregoing embodiment is based on the summary portrait of all the information of the customer in the APP of multiple business departments, combined with the personal user portrait for product information recommendation, so that the recommended product is more accurate, thereby further improving the user experience. For example, according to the customer's inquiry request for loan information and the portrait of all the information of the customer in the message chain, the recommendation of related products such as loans and/or loans is made.

In an optional embodiment, in the method for sharing APP messages based on the blockchain, after each APP sends a message to the corresponding area, different types of messages are classified and stored using different business templates. Among them, the different types of messages can be the user's personal identity, the user's transaction information, the product marketing information, and the system announcement information. Further, according to different message types and the business template storing the message, different display ports are allocated to perform a summary display of different types of messages. The display port is an entrance for displaying the results of the message query to the user, and different types of messages are displayed in different display ports. For example, the user can view the inquired credit card information from the first display port, and the user can display the information from the second display port. Check the debit card message inquired on the port. But not limited to this, the display port can be displayed according to specific rules. For example, two types of messages of credit card transaction messages and debit card messages are stored using business template A and business template B respectively, and subsequently passed Two different business templates, you can specify rules to display the message content corresponding to different business templates to customers in different display ports according to the business template. For example, according to the display port B1 not to display credit card transaction messages, display port A1 The specified rules for debit card transaction messages are not displayed. In this embodiment, the blockchain-based APP message sharing method uses different business templates to classify and store different types of messages, and displays different message contents in different display ports according to specified rules, ensuring the message chain The content of the message cannot be tampered with, which ensures the security of data transmission, improves the reliability of message storage, and facilitates subsequent message queries for each APP, thereby further improving the APP user experience.
