A blockchain-based digital identity management system and method for Internet of Things devices

Abstract

The invention discloses a blockchain-based digital identity management system for Internet of Things devices and a method thereof. The system includes: Internet of Things devices, a digital identity management block chain, a device network client, a manufacturer of Internet of Things devices, Query verifiers and distributed databases; the method mainly includes steps: digital identity registration of IoT devices, digital identity storage of IoT devices, digital identity query and verification of IoT devices. The present invention can realize the uniqueness of the digital identity of the Internet of Things device, and the non-tampering and traceability of the digital identity record, and provide more secure and credible digital identity registration, storage, verification and other services for the Internet of Things device.

Description

technical field [0001] The invention relates to the field of digital identity management technology and information security, in particular to a block chain-based digital identity management system for Internet of Things devices and a method thereof. Background technique [0002] Through the perception of the physical world, the Internet of Things realizes the dynamic acquisition, intelligent processing, seamless interaction and collaborative sharing of information in the physical world, and builds the interconnection of things and things, things and people. The identity of the IoT device is used to uniquely identify the physical and logical entities in the IoT within a certain range, so that the network or application can control and manage the target object based on this, and obtain, process, transmit and exchange related information. [0003] Compared with the Internet, the identity of the Internet of Things identifies computers and communication devices mainly including ...

AI Technical Summary

Problems solved by technology

Identity information hosting institutions need to spend a lot of resources for system security protection, but for hackers, a centralized system that stores a large amount of identity information is a very obvious target, and it is inevitable that hackers destroy the system and defense is difficult high

[0007] 2. Tampering of identity marks

The identity information of the owner will be recorded in detail in the custody system managed by the organization. Administrators with super authority or hackers who successfully break through the system may modify and delete the information of the identity identification, which is not easy to detect.

[0008] 3. The identity owner has low control over their identity information

After the identity information is submitted to the custodian agency, it will basically be out of the control of the owner. The owner no longer has sufficient authority over where the submitted information is used, whether it is illegally sold, or whether it is tampered with on the platform. Informed of the complete situation and powerless to make any decisions
