specific Embodiment approach
[0121] In detail, the specific implementation of each module of the block chain-based smart contract business card device 100 is as follows:
[0122] Step 1. Obtain the user's basic information and the user's blockchain account, and activate the user's blockchain account.
[0123] In the embodiment of the present invention, the basic user information may be the basic information of multiple employees in a certain company, such as employee names, positions, email addresses, employee ID numbers, and contact information. Basic user information can be obtained from a third-party database, wherein the third-party database is a database that stores a large amount of user-related information, and realizes centralized control and management of data.
[0124] Specifically, the activation processing of the user blockchain account includes:
[0125] Query the corresponding user according to the user block chain account number, and obtain the corresponding public key of the user;

The invention relates to a block chain technology, and discloses an intelligent contract business card method based on a block chain, which comprises the following steps: after a user block chain account is activated, indexing mechanism information of a mechanism to which the user block chain account belongs, respectively writing the user block chain account, the user identifier in the user basic information and the organization block chain account in the organization information into a plurality of account fields of the initial business card, generating an encryption key and a decryption key corresponding to the encryption key, encrypting personal information in the user basic information by using the encryption key to obtain encrypted information, and sending the encrypted information to the user block chain account. And calculating a hash value of the personal information, writing the hash value, the encryption key and the encryption information into a content field in the initial business card, encrypting the decryption key by using the public key of the institution account and the public key of the employee account, and writing the encrypted decryption key into the field to obtain the user business card. The invention further provides an intelligent contract business card device based on the block chain, electronic equipment and a storage medium. The problem that the safety of business card generation is not high enough can be solved.
Description
technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain-based smart contract business card method, device, electronic equipment and computer-readable storage medium. Background technique [0002] In the work and social life of all walks of life, business cards have always played an indispensable role. It is indispensable to hand over your own business cards when facing customers. However, with the changes in consumption patterns and the popularity of the Internet, face-to-face marketing It is no longer the only way, and many users are gradually using the Internet to provide another consumption mode, and electronic business cards are also produced in response to the consumption mode of the Internet. [0003] The existing electronic business card generation method is usually to obtain user-related data from the merchant's database, and combine the existing business card template to generate electronic business...
