Privacy protection method of smart home privacy protection system based on blockchain

Abstract

The invention discloses a blockchain-based smart home privacy protection system and privacy protection method, including smart home equipment, nodes, and management nodes; wherein, the nodes include an interface module, a storage module, a processor, a program storage module, and a communication module ; wherein the program storage module is installed with a privacy protection device, including a secret key management module, an encryption service module, and a rights management module. The smart home privacy protection method of the present invention includes: establishing a block chain system with a node as a unit; verifying the data access authority of the smart home equipment; and authenticating the remote control authority of the smart home equipment. The blockchain-based smart home privacy protection system and method of the present invention has the characteristics of low system space occupation rate and huge attack cost, and can safely and reliably protect the privacy of smart home devices.

Description

technical field [0001] The present application relates to the computer field, in particular to a privacy protection method of a blockchain-based smart home privacy protection system. 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 provides a privacy protection method of a block...
