Abstract

The invention discloses a personal information authorization method based on blockchain, which includes: a first user uploads personal information to a first consortium chain; the first user uploads a personal information authorization agreement to a second consortium chain; The user downloads the personal information authorization agreement through the second alliance chain, and verifies the second user's request according to the personal information authorization agreement; the first user sends a time-limited and / or limited-time first alliance link entry to the second user according to the verification result. Authorization; the second user accesses the first consortium chain and obtains the personal information of the first user. The invention also discloses a block chain-based personal information authorization system. In the present invention, a block chain-based personal information authorization method and system realizes personal information storage and authorization on the chain by configuring the information interaction relationship between two alliance chains and public chains, and reduces the risk of personal information leakage, while seeking It has reached the balance between efficiency and security in personal information authorization.
