Privacy protection system with autonomously controllable distributed ledger and cluster architecture thereof

Abstract

The invention discloses a privacy protection system with an autonomously controllable distributed ledger and a cluster architecture thereof. The privacy protection system comprises a channel management module used for providing management channel services including channel creation and updating operations, wherein the participation of channels has authority control, so that a user cannot join a specified channel at will, and only the user meeting the specified channel condition can join the channel; a private data set management module used for providing private data set management services including operations of creating, updating, sharing and clearing a private data set, so that the service data of a user is autonomously controlled by the user, a data sharing object is specified, and a data clearing mechanism is specified; and an identity confusion management module used for providing identity confusion management services including verifiable certificate release, verifiable statement generation and verifiable statement verification operation, so that the user can autonomously control the display of his / her own identity information and can complete related authority verification on the premise of not displaying original information.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular, to an autonomous and controllable distributed ledger privacy protection system and its cluster architecture. Background technique [0002] In the existing blockchain technology, distributed ledger technology is an emerging technology in which several computer devices jointly participate in "bookkeeping" and jointly maintain a complete distributed database. Due to the characteristics of blockchain technology such as decentralization, openness and transparency, each computer device can participate in database records, and data synchronization between computer devices can be quickly performed, distributed ledger technology has a wide range of applications in many fields. application. [0003] The general characteristics of distributed ledger technology are information transparency, sharing, traceability and extensive participation, including: [0004] (1) Transparency: ...

AI Technical Summary

Problems solved by technology

[0006] (3) Traceability: refers to the fact that the storage of data may be permanent, which prolongs the storage time and makes it difficult for information to be forgotten;

[0017] ①Current technology cannot make private information be forgotten;

[0018] ②The current technology uses complex cryptography technology, and the calculation task is heavy, which may become a performance short board and drag down efficiency;

[0019] ③Current technology cannot make private data private and controllable;

[0020] ④Under the current technology, user identity information cannot be displayed in a controllable manner;

[0021] ⑤Under the current technology, user privacy information cannot control the scope of exposure
