IoT security and data privacy protection system based on blockchain

Abstract

The invention discloses a block chain-based internet of things safety and data privacy protection system. The system comprises an internet of things safety engine corresponding to internet of things equipment, and a block chain network communicated with the internet of things safety engine. The establishment of an access session channel with the internet of things equipment of an accessed party isrealized through the block chain network by the application program or the internet of things equipment of an access initiator. Meanwhile, the paid acquisition of the data usage right and the node accounting are completed through the block chain network according to data stored by the internet of things safety engine and corresponding digital right requirements. The internet of things safety engine can automatically carry out the data encryption and decryption operation and the data transaction packaging operation. According to the invention, a block chain network-based internet of things equipment unified key distribution mechanism is realized, so that the authorized use of the internet of things equipment and the establishment of a trust mechanism are effectively realized. Meanwhile, based on the block chain network, the data privacy and the data rights are protected. Therefore, the privacy protection safety of the data of the internet of things equipment is greatly improved.

[0002] At present, the Internet of Things has become an important part of the Internet, and the number of global Internet of Things devices has maintained rapid growth. In the future Internet of Things, any individual, group, community, organization, object, product, data, service, process, and activity will They will be interconnected through the Internet of Things, and the privacy of personal data and commercial secrets in the Internet of Things have become an important shortcoming restricting the development of the Internet of Things. The current research and solutions on the security and privacy technologies of the Internet of Things have not played a good role in guaranteeing , Internet of Things security risks cause growing concern

[0003] Although there are various types of IoT security and data privacy solutions in the industry, none of these solutions can provide a good support for the unified key distribution mechanism, and the data abuse and privacy violations of IoT devices have failed. Find a more general solution
