Embodiment 1

[0063] Embodiment 1: A method for issuing business cards based on blockchain, such as figure 1 shown, including the following steps:

[0064] S100. Obtain the business card information and secret key data input by the owner, wherein the secret key data includes an administrator public key and an administrator private key, generate a first random number based on the business card information, and perform a process on the business card information through the first random number Encrypt to obtain the first business card information, encrypt the first random number with the administrator's public key, and obtain the encrypted first random number;

[0065] S200. Combine the first business card information, the encrypted first random number, and the administrator's public key to form a first data packet, and store the first data packet in a blockchain node;

[0066] S300. Receive the audit instruction, obtain the first data packet from the block chain node, and perform decryption ...

Embodiment 2

[0101] Embodiment 2, a kind of business card issuing system realized based on block chain, such as figure 2 As shown, it includes generating an encrypted business card module 100, an on-chain module 200, a signature business card module 300 and a distribution business card module 400;

[0102] The module 100 for generating encrypted business cards includes an acquisition module 110 and an encryption module 120. The acquisition module 110 is used to acquire business card information and key data input by the owner, wherein the key data includes administrator public keys and management key data. The member's private key; the encryption module 120 is used to generate a first random number based on the business card information, encrypt the business card information by the first random number to obtain the first business card information, and encrypt the first random number by the administrator's public key, Obtain the encrypted first random number;

[0103] The on-chain module ...

Abstract

The invention discloses a business card issuing method and system based on a block chain, and the method comprises the following steps: obtaining business card information and secret key data inputtedby an owner, generating first secret key data and a first random number, obtaining the first business card information, and obtaining an encrypted first random number; combining the first business card information, the encrypted first random number and an administrator public key to form a first data packet, and storing the first data packet to a block chain node; receiving an auditing instruction, obtaining the first data packet, and auditing the first data packet to generate a second data packet; and receiving a distribution instruction, obtaining the second data packet from the block chainnode, performing a series of processing to obtain third business card information, and sending the third business card information to a business card receiver. The method and the system provided by the invention are established based on the block chain, perfectly combine the signing and issuing of a block chain and business cards, and can ensure that the data cannot be tampered and is durable andeffective; and the security of employee identity anti-counterfeiting and company identity data is ensured by adopting a centralized architecture.

Description

technical field [0001] The present invention relates to the application technical field of block chains, in particular to a method and system for issuing business cards based on block chains. Background technique [0002] In the prior art, in order to improve security, it is often necessary for multiple people to authorize at the same time to operate a certain business. In the existing technology, multiple people use different signing devices to generate multiple complete digital signatures respectively, and then perform digital signature verification in turn, and confirm that the business can be carried out after all the multiple complete digital signatures are verified. operate. In order to generate a complete digital signature, the signature device used in the prior art stores a complete private key, which is easily obtained by others through illegal means, reducing the security of the private key. Of course, using a digital signature client implemented in the form of s...
