Description

Method and device for synchronizing telecommunication account number change

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for synchronizing a telecommunication account change with a third-party application.

Background

In the present society, a mobile phone number is not only an identifier of a user identity in a telecommunication operator system, but also an important component of an internet application account system. The internet application can perform operations such as account registration, user identity recognition, account information change and the like in a mode of inputting a mobile phone number by a user and verifying the mobile phone number by a short message. But when the original user sends a change to ownership of the mobile phone number, for example, the mobile phone number is cancelled. At this time, the operator can repeatedly allocate the mobile phone number to a new user for use, that is, the number is placed for the second time.

Fig. 1 is a schematic diagram of a secondary number allocation process, as shown in fig. 1, illustrating some problems existing after the secondary number allocation. In the operator system, user 1 first opens an account at the operator, who issues mobile phone number a to user 1. At this time, the user 1 has the right to use the number a. The user 1 then makes an account registration in the internet application using the mobile phone number a. When the user 1 gives up using the mobile phone number A, the user proposes a sales account to the operator and performs sales account processing. The operator withdraws the mobile phone number A and releases the use right of the user 1 to the mobile phone number A. At this time, when the user 2 opens an account with the operator, the operator can issue the mobile phone number a to the user 2, and the user 2 has the right of use for the mobile phone number a. When the user 2 also wants to register an account in the corresponding internet application, the user 2 cannot register the account again because the user 1 has already registered by using the mobile phone number before. The attribution of the mobile phone number is changed, but the binding relationship between the mobile phone number and the internet application account is not changed.

For a new user, when the new user registers an internet application account with the same mobile phone number, the new user cannot successfully register because the mobile phone number has been registered by the original holder, and even the new user may modify the password of the internet application account of the original user in a short message verification manner and harm the security of the internet application account information and property of the original user. The reason for the problem of secondary number allocation is that when ownership of the mobile phone number is changed in the telecommunication operator system, a channel for information sharing and a mechanism for data linkage updating are lacked between the telecommunication operator system and the internet application system.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Receiving customer sales information through a block chain link point corresponding to an operator management system in a block chain network, and storing the customer sales information into the block chain network; the internet application account management system can perform account unbinding processing according to the mobile phone number and the account cancelling time of the account cancelling in the account cancelling information in the blockchain network.

The application is applied to a block chain network system, and as shown in fig. 2, fig. 2 is a schematic view of an application scenario of a method for synchronizing a telecommunication account change according to an embodiment of the application.

As shown in fig. 2, this scenario illustrates multiple telecommunications carriers and internet applications building a blockchain network and holding corresponding blockchain link points.

Blockchain (blockchain) is a distributed book technology used to record and store data. The blockchain network is composed of a plurality of mutually independent distributed nodes, and the plurality of mutually independent distributed nodes jointly determine which data can be written into the blockchain. Visible blockchains do not require a centralized node to establish and maintain trust relationships in the network. After data is written into the block chain, all nodes in the network keep the same account book and maintain the validity of the account book together. The distributed, decentralized and distrust-removing characteristics of the block chain enable the block chain to store data certificates which are approved and known by multiple parties and form a reliable data sharing and synchronizing mechanism.

A typical method for storing records in a blockchain is as follows: when data to be processed needs to be written into a block chain, the data is transmitted to a block chain node in a network in a broadcast mode through a block chain network, and the node determines whether the data can be written into the block chain or not through a consensus algorithm. Successfully written data is stored as records in blocks (blocks), where a block may store one or more records and a particular hash value is generated based on the contents of the records in the block. The latter chunk includes not only the new record but also the hash value of the previous chunk chain. The hash value is a method for abstracting information, that is, a record occurring in the current time is stored in a subsequent block, and an abstract recorded in a previous block is also stored. The block chain ensures the reliability of data and is difficult to be tampered by the method that the recorded contents are connected in sequence. All nodes in the network can synchronously update the increase of the block record content, so that the effect of jointly storing the same record by the participants is achieved.

The operator management system a, the operator management system B, the operator management system C as shown in fig. 2 represent different telecommunications operators. The operator management system A is connected with the block chain node 1 through a first type interface, the operator management system B is connected with the block chain link point 3 through a first type interface, and the operator management system C is connected with the block chain link point 5 through a first type interface. And the internet application account management system a, the internet application account management system B and the internet application account management system C represent different internet applications. The internet application account management system A is connected with the block chain link point 2 through a second type interface, the internet application account management system B is connected with the block chain link point 4 through a second type interface, and the internet application account management system C is connected with the block chain link point 6 through a second type interface.

In the scene, the operator management system writes the mobile phone number pin number record into the corresponding block chain node in the block chain, and the block chain node encrypts and signs the pin number information and broadcasts the pin number information to other block chain nodes in the block chain network. The block chain node shown in fig. 2 includes a block chain client and a peer node. And the block chain client and the peer node are connected through a third type interface. The block chain client is used for encrypting and signing information and sending the encrypted and signed information to the peer node. The peer nodes are used to broadcast and verify the validity of the encrypted and signed information. And for the block link points corresponding to the internet application management system, checking whether the internet application subscribes to the sales information notification service or not through an intelligent contract. To determine whether the block link point has the right to decrypt the encrypted and signed broadcast information. And for the block chain link points with the authority, the number information of the mobile phone number can be received in real time through the block chain network. And feeding back the information to the corresponding internet application account management system. The internet management system checks whether the mobile phone number of the sales number and the internet account number have a binding relationship, and performs corresponding operation. Meanwhile, the corresponding internet application account management system also writes the processing result into the block chain network as the correspondence of the information sent to the operator. For the block chain network, the number sale reminding of the operator for the mobile phone number and the response after the reminding is received by the internet application are saved, and the multi-party synchronous sharing of the mobile phone number use state change record and the corresponding processing record is realized.

Fig. 3 is a schematic diagram of a block link point structure provided in an embodiment of the present application.

In an example, the application scenario as described in fig. 2 may be implemented in a hyper ledger project (hyper Fabric, hereinafter referred to as Fabric) blockchain, where an operator management system a stores information I "mobile phone number a has been sold", and an internet application account management system B synchronizes the information I and sends out response information. It can be assumed that all participants have established a blockchain network as shown in figure 2 together and have all joined. And meanwhile, all participants generate own public and private key pairs. The public key is public to all participants in the blockchain network, while the private key holds itself. The operator management system communicates with the blockchain network through a first type of interface, and the internet application account management system communicates with the blockchain network through a second type of interface.

Fig. 3 is a schematic structural diagram of 6 blockchain nodes in fig. 2. The blockchain node in fig. 2 is merely a simplified example, and fig. 3 will describe the blockchain node in more detail.

The blockchain node comprises a blockchain authority management module (membership), a blockchain client (client), a peer node (peer) and a sequencing module (sender). The blockchain client may also be referred to as application, and the peer node may also be referred to as node. In one embodiment, the peer node further includes an endorsement module (endorser), a validation module (commit), an event module (event), a chain code (chaincode), and a shared book (legger). Wherein the chainode may also be referred to as a smart contract (smart contract).

First, before the blockchain client communicates with the peer, the identity authentication needs to be performed to the blockchain authority management module. The block chain authority management module issues a certificate to a block chain client, and meanwhile, the block chain authority management module also stores an asymmetric encrypted public and private key pair and a first key for encrypting information, and performs identity authentication, authorization and management on members who join a block chain network. After the identity of the blockchain client is proved to be valid, the blockchain client sends a transaction request to a request endorsement module to endorse. The endorsement module is used for carrying out validity check on the transaction submitted by the blockchain client and carrying out endorsement on the valid transaction. The endorsement module checks whether the transaction has a valid identity of the blockchain client and whether the transaction proposed by the blockchain client can have adverse effects on the blockchain network. And after the endorsement module passes the check, the transaction is endorsed and returned to the blockchain client. And submitting the transaction after the block chain client receives the information returned by the endorsement. For blockchain nodes that may contain multiple blockchain customer orders, then there may be many transactions submitted over a period of time, and then all submitted transactions are globally ordered by the ordering module. The verification module verifies the transactions sequenced by the sequencing module one by one. The verification module is used for executing the sequenced legal transactions, wherein whether the transactions are executed or not needs to be verified. For example, if the transaction is that a and B have traded 1 piece of money, the verification module needs to verify whether the 1 piece of money has really traded. For example, in a scenario of application of the present application, it may be verified whether a number in a transmitted transaction request is a mobile phone number, for example, a digit number of the number or other equivalent operations may be verified, and the present application is not limited in any way. And the transaction which is verified by the verification module is sent to the event module, and the event module generates an event and sends the event to the intelligent contract. And determining whether the condition for accessing the shared ledger is met by the intelligent contract. And when the condition is met, writing the event into the shared account book for storage. The intelligent contract is generally provided with a preset contract triggering condition, and when the triggering condition is met, the intelligent contract is automatically executed and a corresponding result is returned. When called, the intelligent contract is executed according to the trigger conditions and rules, and the content of the contract is written into the block chain account book.

The internet application account management system can adopt a subscription mode to ensure the right of obtaining the information I, and the internet application account management system which is not subscribed or is not in the subscription validity period can not obtain the information I. In order to realize the function, the key distribution rule is set by the intelligent contract of the block chain node corresponding to the internet application account management system, namely, whether the internet application account management system is in the subscription validity period is checked, and if the internet application account management system is not in the subscription validity period, the key cannot be acquired. Meanwhile, a symmetric key distribution service, namely a first key, is added in the blockchain authority management module. The service provides the same key for the operator management system to encrypt the information I and the internet application account management system to decrypt the information I.

Fig. 4 is a flowchart of a method for synchronizing telecommunication account change according to an embodiment of the present disclosure.

As shown in fig. 4, a method for synchronizing telecommunication account change is provided, where the method is executed by a block chain node corresponding to the operator management system shown in fig. 2, and a structure of the block chain node is shown in fig. 3, which is not described herein again. In a block chain network applied by the method, a block chain link point corresponding to an operator management system is a first node, and a block chain link point corresponding to an internet application account management system is a second node, and the method comprises the following steps:

s401, the first node receives the account cancellation information.

In one embodiment, the subscriber information includes a cell phone number of the subscriber. In another example, the sales information may also include sales time.

In one example, the first node receives the subscriber information sent by the operator management system; wherein the sales information is determined by the operator management system according to the sales request.

Firstly, when the user of the mobile phone number does not use the number any more, a user cancellation request is made to the telecom operator. And the operator management system of the telecom operator performs subscriber cancellation processing on the mobile phone number. And after the operator management system performs account cancellation processing on the mobile phone number, sending information such as the mobile phone number of the account cancellation, account cancellation time and the like to the block chain node corresponding to the operator management system. In one example, a blockchain client in a blockchain node receives subscriber information sent by an operator management system.

After the first node receives the account-cancelling information, the account-cancelling information is stored in the block chain network, so that an internet application account management system corresponding to the second node can perform account unbinding processing according to the mobile phone number of the account-cancelling.

Wherein, storing the subscriber information into the block chain network is a conventional operation of the block chain technology. In one embodiment, this may be performed by,

s402, the sales information is encrypted through the first secret key to obtain the encrypted sales information.

In one example, the encrypted sales information may be signed, and the encrypted sales information is signed by using asymmetric encryption to obtain encrypted and signed sales information. In the block chain technique, the information is usually signed for verification by other nodes, but it should be noted by those skilled in the art that any equivalent method may be used instead, and the present application is not limited thereto.

After receiving the account cancelling information, a blockchain client in the blockchain node applies a symmetric key, namely a first key, for encrypting the information to a blockchain authority management module. The subscriber information is then encrypted by the first key. And then, signing the encrypted account information by using a private key held in the asymmetric key to obtain the encrypted and signed account information.

Asymmetric encryption consists of two types of keys: a public key and a private key. The public key and the private key appear in pairs. For the assumed participant a, the public key of a is public to all, and the private key belongs to a only. A public-private key pair may be used to sign and verify messages. Participant a signs the message using the private key and the other participants verify whether the signature was originated by a using a's public key, thus providing a way to verify the authenticity of the origin of the message. Therefore, the asymmetric encryption consisting of the public and private key pairs allows public key to be circulated in a public way, and is suitable for information encryption transmission in an untrusted environment.

And S403, sending the encrypted and signed account cancellation information to the blockchain network.

In one example, the blockchain client sends encrypted and signed customer information into the blockchain network. At this time, the block link point does not write the encrypted and signed account information into the shared account at once, and the block link point needs to wait for the other block link points to verify the encrypted and signed account information.

S404, receiving the broadcast verification information of other nodes except the first node, and writing the encrypted and signed account information into a shared account book for storage according to a consensus algorithm. So that the Internet application account management system can perform account unbinding processing according to the mobile phone number of the seller and the seller time.

In one example, the first node receives a verification message broadcast by other tile chain nodes than itself. The verification message is a verification message after verifying the encrypted and signed sales information. And then writing the encrypted and signed account information into a shared account book for storage according to a preset consensus algorithm. The Internet application account management system can conveniently perform account unbinding processing according to the mobile phone number and the account cancelling time of the account to be cancelled, which are stored in the shared account book.

Fig. 5 is a flowchart of another method for synchronizing a telecommunication account change according to an embodiment of the present disclosure.

After step S403 in fig. 4, the other block nodes receive the encrypted and signed account information and need to verify the encrypted and signed account information, and synchronize the encrypted and signed account information, which includes the specific steps shown in fig. 5.

As shown in fig. 5, the blockchain network further includes a third node, where an operator management system corresponding to the third node is different from an operator management system corresponding to the first node, and the method further includes the following steps:

s501, encrypted and signed account information sent by a third node is received.

In an example, when the first node corresponding to the operator management system is not the block chain node that sends the encrypted and signed customer information, the block chain node corresponding to the operator management system may further receive the encrypted and signed customer information sent by the third node. The third node is a block link point which is used for sending encrypted and signed account information except for the node of the third node.

And S502, verifying the encrypted and signed account information sent by the third node.

In one example, the encrypted and signed account information sent by the third node is subjected to signature verification through asymmetric encryption.

In another example, the authenticity of the encrypted and signed customer information sent by the third node is verified.

In one example, since the operator management system corresponding to the block link point is endorsed, it can be assumed that the information sent by the operator management system corresponding to the block link point is real and reliable. At this time, it is only necessary to verify whether the information is really sent by the third node, and it is not necessary to verify whether the content of the information is real and reliable again.

In one embodiment, a verification module in the blockchain node verifies the encrypted and signed customer information sent by the third node. And the verification module verifies the encrypted and signed account information through a corresponding public key of a third node in the asymmetric encryption, and verifies whether the information is really sent by the third node. And S503, broadcasting the verification result message.

And broadcasting the verified verification result message to the blockchain network so that other blockchain nodes can receive the verification result message and perform subsequent operation.

And S504, receiving the broadcast verification result information of other nodes, and writing the encrypted and signed account information sent by the third node into the shared account book for storage according to the consensus algorithm.

For the encrypted and signed account information sent by the third node, the node also needs to receive the verification result information broadcast by other nodes. And then writing the encrypted and signed account information sent by the third node into the shared account book for storage according to the consensus algorithm. In an example, for example, if the consensus algorithm determines that all blockchain nodes need to be verified, the node needs to receive verification result messages of all blockchain nodes, and after all the verification results pass, the encrypted and signed account information sent by the third node may be written into the shared account book for storage. In another example, for example, if the consensus algorithm determines that more than half of all the blockchain nodes need to be verified, the node needs to receive the verification result messages of other nodes, and when more than half of the verification result messages are verified, the encrypted and signed account information sent by the third node may be written into the shared ledger for storage. Therefore, the synchronization of the information of the chain nodes of different blocks in the block chain network is realized.

Fig. 6 is a flowchart of another method for changing a synchronous telecommunications account according to an embodiment of the present application.

As shown in fig. 6, another method for synchronizing telecommunication account number change is provided, where the method is executed by block chain nodes corresponding to the internet application account management system shown in fig. 2, and the structure of the block chain nodes is shown in fig. 3, which is not described herein again. In a block chain network applied by the method, a block chain link point corresponding to an internet application account management system is a first node, and a block chain link point corresponding to an operator management system is a second node, and the method comprises the following steps:

s601, the first node receives account cancellation information; the information of the seller comprises the mobile phone number of the seller.

In one example, the customer information may be formed by encrypting with the first key. The block chain node receives the encrypted and signed account information sent in the step shown in fig. 4.

In another example, the sales information further includes a sales time.

S602, decrypting the encrypted and signed account information to obtain account information. And when the time of the account to be unbound is later than the registration time of the account to be unbound, the account to be unbound and the mobile phone number of the account to be unbound are unbound.

In one embodiment, the encrypted and signed customer information is decrypted through the first key to obtain the customer information.

In one example, an intelligent contract in a blockchain node detects whether the internet corresponding to the node is subscribed to a sales information notification service by a management system. And when the subscription validity period is detected to be within the subscription validity period, requesting the block chain authority management module to acquire a symmetric encrypted key, namely the first key. And then the peer node in the block chain node decrypts the encrypted and signed account cancelling information according to the first key to obtain account cancelling information, namely the mobile phone number and account cancelling time of the account cancelling.

And after the first node receives the account cancelling information, sending the account cancelling information to an internet application account management system corresponding to the first node for unbinding operation. When processing result information sent by an internet application account management system corresponding to the first node is received, storing the processing result information into the block chain network; and the processing result information shows that the account number to be unbound and the mobile phone number of the seller are unbound.

The storage of the processing result information into the blockchain network is a conventional operation of the blockchain technology. In one embodiment, this may be performed by,

and S603, sending the information of the account of.

In one example, the blockchain client sends the account information obtained after decryption to a corresponding internet application account management system. And then the Internet application account management system checks whether the mobile phone number has a binding relationship with the Internet account or not according to the mobile phone number and the account-cancelling time of the user in the user-cancelling information. If the binding relationship exists, whether the registration time of the internet account is before the account selling time is checked. And if the registration time of the internet account is earlier than the time of the account cancellation, indicating that the internet account is registered before the account cancellation, and performing corresponding unbinding operation on the internet account and the mobile phone number of the account cancellation.

S604, receiving processing result information sent by the application management system; the processing result information shows that the account number and the mobile phone number of the seller are unbound;

in one example, the internet application account management system generates processing result information, i.e., response receipt information, as a response to the information of the account holder in S401 shown in fig. 4 according to the result of the unbinding operation, and sends the processing result information, i.e., the response receipt information, to the corresponding block link point of the internet application account management system.

And S605, signing the processing result information to obtain the signed processing result information.

In an embodiment, the processing result may also be signed by asymmetric encryption, so as to obtain signed processing result information. In the block chain technique, the information is usually signed for verification by other nodes, but it should be noted by those skilled in the art that any equivalent method may be used instead, and the present application is not limited thereto.

In one example, a block chain client in a block chain node signs received processing result information by using a private key held by the block chain client in an asymmetric key, so as to obtain signed processing result information.

And S606, sending the signed processing result information to the block chain network.

In one example, the blockchain client sends the signed processing result information to the blockchain network. At this time, the block link point does not write the signed processing result information into the shared book immediately, and the block link point needs to wait for the verification of the signed processing result information by other block link points.

And S607, receiving the broadcast verification messages of other nodes except the first node, and writing the signed processing result information into the shared account book for storage according to the consensus algorithm.

In one example, the first node receives a verification message broadcast by other tile chain nodes than itself. The verification message is a verification message obtained by verifying the signed processing result information. And then writing the signed processing result information into a shared account book for storage according to a preset consensus algorithm. The history record is provided for the change of the state of the mobile phone number and the change of the binding state, and the dispute is favorably acquired and chased after disputes occur.

Fig. 7 is a flowchart of another method for changing a synchronous telecommunications account according to an embodiment of the present application.

After step S606 in fig. 6, the processing result information after the other block nodes receive the signature needs to be verified and synchronized, and the specific steps are as shown in fig. 7.

As shown in fig. 7, the blockchain network further includes a third node, where an internet application account management system corresponding to the third node is different from an internet application account management system corresponding to the first node, and the method further includes the following steps:

s701, receiving the signed processing result information sent by the third node.

In an example, when the first node corresponding to the internet application account management system is not the block link point that transmits the signed processing result information, the block link point corresponding to the internet application account management system may further receive the signed processing result information transmitted by the third node. The third node is a block link node which transmits the signed processing result information except the node itself.

And S701, verifying the signed processing result information sent by the third node.

In one example, the signed processing result information sent by the third node is subjected to signature verification through asymmetric encryption.

In another example, the authenticity of the signed process result information sent by the third node is verified.

In one example, since the internet application account management system corresponding to the block link point is endorsed, it can be assumed that the information sent by the internet application account management system corresponding to the block link point is real and reliable. At this time, it is only necessary to verify whether the information is really sent by the third node, and it is not necessary to verify whether the content of the information is real and reliable again.

In one embodiment, a verification module in the blockchain node verifies the signed processing result information sent by the third node. And the verification module verifies the signed processing result information through a corresponding public key of a third node in the asymmetric encryption and verifies whether the information is really sent by the third node.

And S703, broadcasting the verification result message.

And S704, receiving the verification messages broadcasted by other nodes, and writing the signed processing result information sent by the third node into the shared account book for storage according to the consensus algorithm.

For the signed processing result information sent by the third node, the node also needs to receive the verification result information broadcast by other nodes except the third node. And then writing the signed processing result information sent by the third node into the shared account book for storage according to the consensus algorithm. In an example, for example, if the consensus algorithm determines that all the blockchain nodes need to be verified, the node needs to receive verification result messages of all the blockchain nodes, and after all the verification results pass, the signed processing result information sent by the third node may be written into the shared ledger for storage. In another example, for example, if the consensus algorithm determines that more than half of all the blockchain nodes need to be verified, the node needs to receive the verification result messages of other nodes, and when more than half of the verification result messages are verified, the signed processing result information sent by the third node may be written into the shared ledger for storage. Therefore, the synchronization of the information of the chain nodes of different blocks in the block chain network is realized.

Through the methods shown in fig. 4 to fig. 7, it is realized that a plurality of telecommunications operators encrypt and sign subscriber information of a mobile phone number through corresponding block link nodes in a block chain network, and then broadcast the subscriber information to other block chain nodes in the block chain network. And simultaneously, decrypting the encrypted and signed account information by the plurality of internet applications through the corresponding block chain link points in the block chain network, and transmitting the decrypted account information to the corresponding internet application system for account unbinding operation. And the plurality of internet application corresponding block chain nodes sign the operation result and broadcast the operation result in the block chain network.

For other schemes, such as a telecommunication operator opening a secondary number allocation inquiry authentication interface, the internet application can send the mobile phone number to be inquired and the time for registering the application account number by the mobile phone number to the authentication interface. Then the telecom operator acquires the number registration time and compares the number registration time with the network access time of the number in the operator management system, and if the registration time is earlier than the network access time, the number registration time is judged to be a secondary number allocation user of the Internet application; and if the registration time is later than the network access time, judging the user to be a new user of the Internet application. And then, returning the judgment result to the Internet application through the authentication interface by the operator. But this solution may have the inability to do cross-operator queries and lack of an active notification mechanism. For different operators, only the mobile phone number use state capable of inquiring the operation of the operator is provided independently, but for the mobile phone number bound to the internet account, the source of the mobile phone number may be different from that of multiple operators, and the internet application needs to identify the operator attribution of the number first and then inquire the number one by one.

Meanwhile, in other schemes, the internet application can set mobile phone number login protection, that is, when the user logs in the application through the mobile phone number and the short message verification code, other information is needed for joint verification. Such as contact relationships, avatars, identification numbers, historical usage records, and the like. Thereby judging that the current login person really holds the account of the internet application. However, the login protection is only applicable to the application with the foreground interface, and the user can operate the login protection manually. For internet applications or services without foreground interfaces, such as incoming call blacklisting. If the phone number is marked as a blacklist number, such as a fraud phone, etc., the user of the phone number cannot touch the blacklist number by manual operation after the phone number is placed for the second time, and the provider of the marking service cannot know the current use condition of the phone number.

Compared with other schemes, the method provides an active notification mechanism of number change between the operator and the internet application: the internet application can process the binding relationship between the mobile phone number and the application almost in real time and accurately so as to reduce the problems that data privacy is leaked and a new user cannot register the application. Meanwhile, a historical record is provided for the change of the mobile phone number state and the change of the binding state of the Internet application between the operator and the Internet application, and the evidence taking and the responsibility tracing and the right confirming are convenient to carry out in the future.

Fig. 8 is a flowchart of a method for synchronizing a telecommunication account change according to an embodiment of the present disclosure.

As shown in fig. 8, first, a user makes a sales request to a Customer Relationship Management (CRM) system of an operator. And then the CRM system of the operator performs subscriber cancellation operation according to the received subscriber cancellation request. After the sales are completed, the operator CRM system packages the mobile phone number of the sales and the sales time into sales information I, and the sales information I is transmitted to the client in the block link point corresponding to the operator CRM system through the first type of interface. And the client of the blockchain node encrypts the information I by using a first key distributed by the system and then signs by using a private key of the operator. And generating encrypted and signed customer cancellation information T, sending the customer cancellation information T to a corresponding node, and broadcasting the information T to other blockchain nodes in the blockchain network by the node. After receiving the information T, the other nodes in the blockchain network verify that the information T is indeed sent by the other nodes using the public key of the operator, and write the information T into the blockchain after reaching the consensus and confirming that the information T is valid.

For a block chain node corresponding to the Internet application, whether the Internet application subscribes to a sales information notification service is checked through an intelligent contract. If the subscription is carried out or the subscription period is not in the validity period, the information T cannot be decrypted by the block chain link points corresponding to the Internet application. If the network application is subscribed and within the subscription validity period, the system allocates a key corresponding to the corresponding block link node point, namely a first key, to the internet application. For decrypting the information T. And decrypting the corresponding block link point of the Internet application to obtain the account information I, and sending the account information I to the corresponding Internet application account management system through the second type of interface by the corresponding client. The internet application account management system can check whether an application account is associated with the application account according to the mobile phone number of the account comprised in the account-cancelling information I, and then make a corresponding processing result according to the account-cancelling time. And after the processing is finished, sending the receipt information Ir as a response to the client of the corresponding block link point of the Internet application. The receipt information Ir may include processing time and processing conditions, for example, the mobile phone number has been unbound from the account. And the client of the block chain link point corresponding to the Internet application signs the receipt information Ir and the private key of the Internet application to form information Tr, sends the information Tr to any node in the block chain network, and broadcasts the information Tr to other block chain nodes in the block chain network by the node. And other block chain link points in the block chain network receive the information Tr, verify that the information is sent by the corresponding block chain node by using a public key applied to the Internet, and write the information Tr into the block chain after the consensus is achieved and the information Tr is confirmed to be valid.

Fig. 9 is a flowchart of another method for synchronizing a telecommunication account change according to an embodiment of the present disclosure.

As shown in fig. 9, a sales account event occurs at the mobile phone number a to which the carrier a belongs, and the CRM system of the carrier a records sales account information of the mobile phone number a. Then, the operator A extracts the related information such as the customer sales time (logout time) and the mobile phone number (logout number) of the customer sales from the CRM system of the operator A, packages the information into customer sales information I, and then transmits the customer of the block chain link point 1 corresponding to the CRM system of the operator A through the first type of interface. The client of the block chain node 1 requests to acquire an encryption key Pm through a symmetric key distribution service E in a membership module of the Fabric, and encrypts the seller information I to form I'. The client then signs the information I' with the private key Pa and packages it into the information T. Wherein, the public key corresponding to Pa is Pa'. The client of the blockchain node 1 sends the information T to the node of the node 1, and the node broadcasts the information T in the blockchain network. And verifying the information T by other block chain link points in the block chain network through the public key Pa', and writing the information T into a shared account book of the block chain after the information T is confirmed according to a consensus algorithm.

After the node of the block chain node 2 acquires the information T, the information T is obtained by signing the information I ', and thus the information T is signed information I'. And then, decrypting the signed information I' by using the Pm to obtain the sales information I comprising the sales time and the mobile phone number of the sales. And the blockchain node 2 transmits the account cancellation information I to the account management system of the corresponding Internet application B through the second type of interface. And the account management system of the Internet application B checks whether the number of the seller is registered in the Internet application account or not through the mobile phone number of the seller in the seller information I, and if the number of the seller is detected to be registered, corresponding unbinding processing is carried out on the application account number corresponding to the mobile phone number of the seller according to the seller time. The account management system of the internet application B packages information such as processing time (response time), processing state (response status), and the like into receipt information Ir, and transmits the receipt information Ir as a response to the received information T to the client of the block link point 2 corresponding to the internet application B through the second type of interface.
