Detailed Description
For a better understanding of the technical aspects of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.
The method aims to solve the problem that communication card data of a changed number of a user is not updated in time, and a series of adverse effects are brought to the user. The disclosure provides a block chain-based card data updating method, system and provider platform. The following detailed description is made with reference to the accompanying drawings which respectively illustrate embodiments provided by the present disclosure.
A brief description will be given of a block chain-based card data update system provided in the embodiment of the present disclosure. As shown in fig. 3, the block chain-based card data update system includes a user equipment 1, an authentication center 2, and a provider platform 3.
The nodes in the blockchain include an authentication center and a provider platform. The user equipment may also access the blockchain through an application. The node in each block chain is provided with a pair of secret keys, a public key and a private key, the private key is stored by the node, and the public key is disclosed in the whole network. The nodes in the blockchain generate blockchain addresses through the public key so that other nodes verify the nodes in the blockchain. All nodes in the block chain can be used as accounting nodes in the block chain network, private key signature verification is carried out on all broadcast information in the block chain network, and the broadcast information is recorded into a block chain account book after the private key signature verification is passed.
In a preferred implementation manner, the system for updating card data based on a blockchain provided by the embodiment of the present disclosure further includes a blockchain platform. And the block chain platform authenticates and manages the nodes in the block chain, generates a private key and a public key for the nodes after the authentication is passed, and broadcasts the public key in the block chain.
In the initial stage, the user equipment is registered in the authentication center, and the user needs to authorize the provider platform according to the actual situation. For example, the user equipment sends a registration request to the authentication center, the authentication center sends an authorization contract page to the user equipment, the user selects according to options provided by the authorization contract page, and the provider platform is authorized, that is, a mapping relationship between a user identifier corresponding to the user equipment and the provider platform is established. The authentication center generates an authorization certificate according to the mapping relation between the user equipment and the provider platform and stores the authorization certificate locally.
Fig. 1 shows a flowchart of a block chain-based card data updating method provided by an embodiment of the present disclosure.
The block chain based card data updating method is applicable to a provider platform, namely, SP/CP. As shown in fig. 1, the block chain-based card data updating method provided in this embodiment includes the following steps.
Step S101, receiving number change information broadcast by the authentication center in the block chain.
Step S102, acquiring a first user identification, a changed number and change information in the number change message.
And step S103, updating the data of the communication card corresponding to the changed number according to the first user identification, the changed number and the change information.
The number change message is broadcast after the authentication center receives the number change message sent by the user equipment and the authentication of the user equipment is passed. When the user transacts the secondary card account opening service, the user applies for a new communication card, and the user equipment sends a number change message to the authentication center. The authentication center authenticates the user equipment according to the first user identifier in the number change message, namely, whether the authorization certificate of the user equipment is stored locally is verified, namely, whether the user equipment is authorized to have a provider platform is verified. If the authentication center inquires that the authorization certificate corresponding to the user equipment is stored, the fact that the user equipment authorizes the provider platform is indicated, and the user equipment is determined to pass the authentication. After the authentication center passes the authentication of the user equipment, the corresponding authorized provider platform can be determined according to the first user identification, and the authorization certificate is sent to the corresponding provider platform for storage. The communication card is a SIM (Subscriber Identity Module) card.
According to the card data updating method based on the block chain, the provider platform receives the number change message broadcast by the authentication center in the block chain, acquires the first user identification, the changed number and the change information in the number change message, and updates the data of the communication card corresponding to the changed number according to the first user identification, the changed number and the change information. The communication card data of the changed number for the user is updated in time, and the user experience is improved.
In some embodiments, the following scenarios are addressed: the changed number purchased by the user in the business hall often receives the short message or consumption prompt of the bank card of the owner and other information sent by the supplier platform and the like, and the user can receive the telephone of the relatives and friends of the owner, so that problems caused by secondary number allocation of the operator are likely to bring many adverse effects to the user. The updating the data of the communication card corresponding to the changed number according to the first user identifier, the changed number and the change information (i.e., step S103) includes: and in response to determining that the changed information is the original bound user information, locally inquiring a first binding relationship among the first user identification, the changed number and the ordering service and a second binding relationship between the changed number and the second user identification, removing the second binding relationship.
The intelligent contract is one of important technical features of the blockchain, and the intelligent contract based on the blockchain not only can exert the advantages of the intelligent contract in the aspect of cost efficiency, but also can avoid the interference of malicious behaviors on the normal execution of the intelligent contract. The intelligent contract is written into the block chain in a digital form, and the characteristics of the block chain ensure that the whole process of storage, reading and execution is transparent, traceable and not falsifiable. Meanwhile, a set of state machine system is constructed by the block chain self-contained consensus algorithm, so that the intelligent contract can run efficiently.
In the embodiment of the disclosure, in order to avoid that the binding relationship between the changed number of the user and the former owner is not released from adverse effects brought to the user, after the provider platform receives the number change message broadcasted by the authentication center, if the change information in the number change message is analyzed to be the original binding user release information, and the locally stored intelligent contract including the first binding relationship among the first user identifier, the changed number and the ordering service and the second binding relationship between the changed number and the second user identifier is inquired, the second binding relationship is released, that is, the second binding relationship between the changed number and the original binding user is released. The second user identification is the identification of the original binding user of the changed number, and the first user identification is the identification of the new binding user of the changed number.
It should be noted that, after the provider platform releases the second binding relationship, a message that the second binding relationship with the original bound user is released is sent to the user equipment. The first binding relationship may also be a first binding relationship between the first Subscriber Identity, the IMSI (International Mobile Subscriber Identity) of the changed number, and the subscription service. The second binding relationship may also be a second binding relationship between the IMSI of the changed number and the second subscriber identity.
In some embodiments, before the updating the data of the communication card corresponding to the changed number according to the first user identifier, the changed number and the change information (i.e., step S103), the method further includes: and receiving and storing the changed number, the first user identifier and the first binding relationship of the subscription service sent by the user equipment.
In the embodiment of the present disclosure, after the user equipment is registered in the authentication center, the user equipment may send the changed number, the first user identifier, and the first binding relationship of the subscription service to the provider platform authorized by the user equipment, and store the first binding relationship in the intelligent contract of the provider platform. And meanwhile, a second binding relationship between the changed number and the second user identifier is also stored in the intelligent contract of the provider platform. Only data that is validated by the user device can be synchronized to the provider platform. Through the safety mechanism of the block chain network, the data of the user can be guaranteed to be issued to the block chain network after being confirmed by the user, and meanwhile, the monitoring and tracing of the authorization voucher can be realized.
In a preferred embodiment, the block chain based card data updating system further comprises a data sharing platform. After the user equipment is registered in the authentication center, the user equipment synchronizes the data which can be shared to the data sharing platform, and after the supplier platform receives the number change message of the user equipment, the first binding relationship and the second binding relationship are obtained through the data sharing platform.
In some embodiments, the following scenarios are addressed: when a user installs an application program on user equipment and binds with a changed number, the user is not in the control range of an operator, so that when the number is changed or cancelled, a third party platform cannot be informed to unbind in time. The updating the data of the communication card corresponding to the changed number according to the first user identifier, the changed number and the change information (i.e., step S103) includes: and responding to the fact that the change information is determined to be the switching service ordering relation information, acquiring a number before change corresponding to the first user identification, and transferring the authorized service ordering relation of the communication card corresponding to the number before change to the communication card corresponding to the number after change.
In the embodiment of the disclosure, in order to avoid adverse effects on the user caused by the fact that the subscription service corresponding to the number before the change of the user is not timely unbound from the third-party platform, if the supplier platform determines that the change information in the number change message is the switching service subscription relationship information, the number before the change corresponding to the first user identifier is acquired from the local or blockchain network, and the authorized service subscription relationship corresponding to the number before the change is transferred to the communication card corresponding to the number after the change. The supplier platform updates the information of the communication card corresponding to the number before the change is transferred to the authorized service ordering relation corresponding to the number after the change in the intelligent contract stored locally, and simultaneously sends a number change indication message to the third party platform corresponding to the authorized service corresponding to the number after the change, so that the third party platform switches the corresponding authorized service from the original bound number before the change to the number after the change. And then, the provider platform sends a message that the service subscription relationship information is switched to the user equipment.
In some embodiments, updating the data of the communication card corresponding to the changed number according to the first subscriber identity, the changed number and the change information (i.e., step S103) includes: and in response to determining that the provider platform is authorized by the user equipment corresponding to the first user identifier, updating the data of the communication card corresponding to the changed number according to the first user identifier, the changed number and the change information.
With the development of various services, the application of blockchains is more and more common in real life, many problems related to data security can be solved by using the blockchains, authorization opening and sharing of user private data can be realized by using the blockchains based on a telecommunication system, and generation, storage, validation and the like of authorization certificates can be realized by combining the authorization flow of the data with a blockchain network and an intelligent contract.
In this step, the provider platform is a platform authorized by the user, and after the authentication center authenticates the user device, the authentication center sends an authorization credential to the provider platform authorized by the user device. And the provider platform with the service subscription binding relationship can continuously execute the step of updating the data of the communication card corresponding to the changed number if the provider platform is determined to be the platform authorized by the user equipment according to the stored authorization certificate.
The following illustrates a block chain-based card data updating method provided by an embodiment of the present disclosure. Suppose that the current new communication card is card 1, the user corresponding to the card 1 during the initial number allocation is A, the user corresponding to the card 1 during the secondary number allocation is B, and the user B has another card 2. And the user B initiates a number change message to the authentication center after applying for opening the card 1, wherein the number change message carries a first user identifier, a changed number and change information, the change information is divided into two types, and the original bound user information or switching service ordering relation information is removed. And the original binding user information is removed to remove the binding relationship between the user A and the card 1, and the service ordering relationship switching information is the authorized service ordering relationship corresponding to the card 2 of the user B transferred to the card 1. After the authentication center passes the authentication of the user B, the block chain broadcasts the number change message, and after the provider platform authorized by the user B receives the number change message of the user, the corresponding service process is carried out, so that the binding relationship between the user A and the card 1 is released or the authorized service ordering relationship corresponding to the card 2 of the user B is transferred to the card 1.
