Smart home privacy protection system and privacy protection method based on block chain

Abstract

The invention discloses a smart home privacy protection system and a privacy protection method based on a block chain. The smart home privacy protection system comprises smart home equipment, nodes and a management node, wherein the node comprises an interface module, a storage module, a processor, a program storage module and a communication module; a privacy protection device is installed in theprogram storage module and comprises a secret key management module, an encryption service module and an authority management module. The smart home privacy protection method comprises the followingsteps of: establishing a block chain system by taking a node as a unit, verifying the data access permission of the smart home equipment, and authenticating the remote control authority of the smart home equipment. The smart home privacy protection system and method based on the block chain have the characteristics of low system space occupancy rate and huge attack initiation cost, and can safelyand reliably protect the privacy security of smart home equipment.

Description

technical field [0001] The present application relates to the computer field, in particular to a blockchain-based smart home privacy protection system and privacy protection method. Background technique [0002] With the development of network and communication technology, the intelligence of household facilities and equipment has become inevitable, and will soon spread to every household. However, all devices are exposed to the public network, and most of them are connected to the public network through wireless networks. Such physical characteristics lead to great challenges in privacy protection. Existing smart homes rely entirely on standardized encryption and centralized cloud management. , In the face of targeted attacks, there are congenital technical defects, and it is only a matter of time before privacy and data leakage. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a blockchain-based smart home privacy p...
