Embodiment 1

[0068] This embodiment provides a blockchain-based method for adding a secondary card for a multi-card service of one number, which is applied to the terminal where the card to be added is located, and the method steps are executed by the terminal node where the card to be added is located. Specifically, as figure 1 As shown, the method includes:

[0069] Step S10, sending a first broadcast message for applying to become a secondary card to the blockchain network, and adding a first private key signature to the first broadcast message.

[0070] In this step, when the card to be added wants to become a secondary card of the main card, the terminal node where the card to be added is located sends a broadcast message to the blockchain network registered as a node, the broadcast message is called the first broadcast message, and the first broadcast message The content of a broadcast message is sent after being signed by the private key of the terminal node where the card to be ad...

Embodiment 2

[0080] This embodiment provides a blockchain-based method for adding a secondary card for a multi-card service of one number, which is applied to the terminal where the main card is located, such as figure 2 As shown, the method includes:

[0081] Step S20: Receive the first broadcast message sent by the terminal node where the card to be added is located, verify the first private key signature of the first broadcast message, and if the verification passes, send a second broadcast message to the blockchain network to inquire about the card to be added information, and a second private key signature is added to the second broadcast message.

[0082] In this step, since the first broadcast information sent by the terminal node where the card to be added is located includes the public key of the terminal node where the card to be added is located, the terminal node where the main card is located can obtain the public key of the terminal node where the card to be added is located...

Embodiment 3

[0095] This embodiment provides a blockchain-based method for adding a secondary card for a multi-card service of one number, which is applied to the home subscriber server, such as image 3 As shown, the method includes:

[0096] Step S30: Receive the fourth broadcast message sent by the terminal node where the main card is located, verify the fourth private key signature of the fourth broadcast message, and if the verification is passed, write the information of the card to be added in the fourth broadcast message into the home contract In the relationship list stored in the user server.

[0097] In this step, the fourth broadcast message includes: the second encrypted information of the card to be added, the blockchain identifier of the terminal node where the main card is located, the public key of the terminal node where the main card is located, and the blockchain identifier of the terminal node where the card to be added is located , the public key of the terminal node...

Abstract

The present invention provides a block chain-based method for adding a secondary card for multi-card business, which relates to the field of communication technology, including: sending a first broadcast message to apply for becoming a secondary card to the block chain network, and adding the first broadcast message to the block chain network The first private key signature; receive the second broadcast message sent by the terminal node where the main card is located, and verify the second private key signature of the second broadcast message, if the verification is passed, send the second broadcast message including the card to be added to the blockchain network An encrypted message, and adding a third private key signature to the third broadcast message. In this method, during the process of adding the card to be added as the secondary card of the main card, the main card and the terminal where the card to be added are located perform information interaction based on the blockchain network, so that the user can know the information of the main card owned by him. The number of secondary cards prevents hackers from secretly adding black cards to users through illegal means, thereby enabling users to manage personal privacy information more securely.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method, a terminal and a system for adding a secondary card for a multi-card business of one number based on a blockchain. Background technique [0002] With the development of society, the number of user terminals held by users is also increasing. In order to meet user needs, operators provide one-number multi-card services, that is, users have multiple calling cards, of which only one is the primary card. , and the rest are secondary cards. The operator only assigns an identification number to individual users. This identification number can be bound with the main card and many secondary cards, so that the main card and many secondary cards use this identification number as the calling number for display. . [0003] In the prior art, when an operator adds a secondary card to a user's one-number multi-card service, the operator generally modifies the user's one-numbe...
