The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation on the present application. In the drawings:

[0041] In order to make the purpose, technical solutions and advantages of this specification more clear, the technical solutions of this application will be clearly and completely described below in combination with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in the specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0043] The embodiments of the present application provide a method and corresponding solution for preventing telecommunications fraud based on blockchain, which protects telecommunications users' information through blockchain encryption technology to prevent hacker attacks; and performs multiple backups of data based on the characteristics of blockchain distributed storage.

[0044] Figure 1 The method flow chart provided in the embodiment of this specification is as follows. As shown in the figure, the method includes:

[0045] S101 stores user information of multiple telecom operators in a blockchain, where the user information is information submitted by the user when applying for a phone number;

[0046] S102 receives the fraudulent number and stores it in the blockchain;

[0047] S103 receives query information from the first telecommunications operator and feeds it back to the first telecommunications operator, so that the first telecommunications operator determines whether to cut off the call of the fraudulent number, wherein the query information is information for querying the fraudulent number.

[0048] Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and a distributed ledger that is cryptographically guaranteed to be tamper-proof and unforgeable. Although the underlying technology of blockchain has been developed for many years, it cannot be effectively applied in specific scenarios.

[0049] According to a specific embodiment of the present invention, in step S101, a smart contract for managing user information and fraudulent numbers is set on the blockchain. The smart contract is an automated script deployed on the blockchain. Since it is set on the blockchain, it has the characteristics of openness and transparency. Users pre-set rules through smart contracts to write data into the blockchain and obtain data browsing permissions, which largely avoids the disclosure of private information. Of course, smart contracts are not the only implementation method of this application, and are set accordingly according to different blockchain platforms, such as Ethereum, Hyperledger, etc.

[0050] According to the specific embodiments of the present invention, the embodiments of the present application do not impose any special restrictions on the setting of the nodes of the blockchain. It can be a blockchain built by the telecom operator itself, or it can be a blockchain jointly built by the telecom operator and relevant regulatory agencies, such as the Ministry of Culture.

[0051] According to a specific embodiment of the present invention, the receiving of fraudulent numbers and storing them in the blockchain includes: receiving fraudulent numbers sent by telecom operators and storing them in the blockchain. In practical applications, there are generally multiple telecom operators in a region, but the information between them is opaque. By storing fraudulent numbers marked by multiple telecom operators in the blockchain, information intercommunication is achieved. Through the encryption technology of the blockchain, each telecom operator can only search through smart contracts, which protects both the business secrets of each operator and the personal privacy of users.

[0052] Correspondingly, in the process of the telecom operator actually providing services, the query information of the first telecom operator is received and fed back to the first telecom operator so that the first telecom operator determines whether to cut off the call of the fraudulent number, including: the smart contract on the blockchain determines whether the fraudulent number is sent by the second telecom operator; if so, it is fed back to the first telecom operator, and the first telecom operator is caused to cut off the call of the fraudulent number.

[0053] Generally speaking, the credibility of the phone number marked by the telecom operator is relatively high. Therefore, when a fraud number marked by the smart contract is detected, the communication operator can choose to directly block the call to prevent the victim from suffering losses and claiming compensation from the operator after suffering losses. Similarly, the highly credible marking information is not only provided by the telecom operator, but also by relevant government agencies or public security, procuratorial and judicial agencies, and the present invention does not impose any special restrictions on this.

[0054] According to a specific embodiment of the present invention, the method of the embodiment of the present invention also provides the following scheme, wherein the receiving of the fraudulent number and storing it in the blockchain includes: receiving the fraudulent number sent by the user or a third-party organization and storing it in the blockchain. The receiving of the query information of the first telecommunications operator and feeding back to the first telecommunications operator so that the first telecommunications operator determines whether to cut off the call of the fraudulent number includes: determining whether the fraudulent number is sent by the user or a third-party organization; if so, feeding back to the first telecommunications operator, and allowing the first telecommunications operator to notify the user of the credibility of the fraudulent number before the call of the fraudulent number.

[0055] Based on blockchain technology, the smart contract receives fraudulent numbers sent by users or third-party organizations, and then uses big data technology to retrieve relevant data of users or third-party organizations, analyze their credibility, and when their credibility reaches a certain target, write the marked fraudulent number into the blockchain. It can be understood that this method can be used not only for fraudulent numbers, but also for marking harassment numbers or numbers for certain daily services, such as express delivery, takeout, etc.

[0056] The smart contract returns the information found in the blockchain to the telecom operator, and the telecom operator displays the credibility of the fraudulent number to the user before the call. If it is a service phone number, it can be selectively marked, which will not be elaborated here.

[0057] According to a specific embodiment of the present invention, in order to improve the enthusiasm of telecom operators, a corresponding reward mechanism can also be designed based on blockchain. In the embodiment of the present application, the corresponding token is sent to the corresponding telecom operator based on the number of fraudulent numbers and the number of interceptions provided by the telecom operator.

[0058] Tokens are circulated encrypted digital certificates of value, which have three elements: equity, encryption, and circulation. The three elements of tokens are indispensable. Digital equity proof: Tokens must be equity certificates in digital form, which represent a right, an inherent and intrinsic value. Encryption: The authenticity, tamper-proofness, privacy protection and other capabilities of tokens are guaranteed by cryptography. Circulation: Tokens must be able to flow in a network so that they can be verified anytime and anywhere.

[0059] According to a specific embodiment of the present invention, in order to ensure that the user information owned by a telecom operator is not known by other telecom operators, thereby causing the leakage of commercial secrets, the user information of the telecom operator can be encrypted using the private key of the telecom operator through the encryption technology of the blockchain and then stored in the blockchain. After the data is written into the blockchain, each operator can receive the data, but without the relevant secret key, it cannot be decrypted and viewed.

[0060] Based on the same idea, some embodiments of the present application also provide devices and non-volatile computer storage media corresponding to the above methods.

[0066] Receive fraudulent numbers and store them in the blockchain;

[0067] Query information from a first telecommunications operator is received and fed back to the first telecommunications operator so that the first telecommunications operator determines whether to cut off the call of the fraudulent number, wherein the query information is information for querying the fraudulent number.
