Problems solved by technology

[0002] At present, personal data information is stored in plain text on the blockchain. This situation obviously has the following disadvantages: the personal privacy data stored on the blockchain cannot be protected; because the data is not protected, the value of the data is also brought into play. Not coming out; there is no market platform for the free flow of data
[0003] Considering that the existing personal data cannot be protected and the value cannot be freely circulated, the present invention implements a blockchain personal data authorization method, which protects personal information by encrypting user data, and then solves the user's request for data through the authorization chain. Authorized decryption, finally allowing user data to flow freely on the authorized chain

Abstract

The invention discloses a personal data authorization method of a block chain. The method comprises: a user encrypts personal data and storing the encrypted personal data on a block chain main chain;a user registering on the authorization chain; when a data order is received on the authorization chain, the authorization chain informs a related user of the order; the user sending the authorizationinformation to an authorization chain, and simultaneously imports the decrypted key into the authorization chain; after receiving user authorization, the authorization chain decrypting the data through the imported secret key; and after the data is decrypted successfully, sending the decrypted data to the order application user. Personal information is protected by encrypting user data, then authorization and decryption of the user on the data are achieved through the authorization chain, and finally the user data can freely flow on the authorization chain.

Description

technical field [0001] The invention relates to block chain authorization, in particular to a block chain personal data authorization method. Background technique [0002] At present, personal data information is stored in plain text on the blockchain. This situation obviously has the following disadvantages: the personal privacy data stored on the blockchain cannot be protected; because the data is not protected, the value of the data is also brought into play. Not coming out; there is no market platform for the free flow of data. [0003] Considering that the existing personal data cannot be protected and the value cannot be freely transferred, the present invention implements a block chain personal data authorization method, which protects personal information by encrypting user data, and then solves the user's request for data through the authorization chain. Authorized decryption finally allows user data to flow freely on the authorized chain. Contents of the inventi...
