Abstract

The invention provides a system and a method for privacy protection in an Internet of Things data security sharing process, and the method comprises an Internet-of-Things data sharing mode, a user uses decentralized attribute-based encryption security sharing encrypted data on a block chain-based platform, and the attribute permission of the user is hidden at the same time. User identities are prevented from being distinguished according to attributes, the privacy of the user is protected, and meanwhile, data encryption sharing and responsibility traceability after privacy leakage are ensured; and the method further comprises a user authority authentication mode based on zero-knowledge proof of attributes, and the real attribute authority of the data user can be safely and reliably verified. The method is suitable for solving the problems of data security sharing and privacy protection of the Internet of Things, and can verify the identity of the user and share the privacy data of the user under the condition of zero knowledge.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, in particular to a system and method for privacy protection in the process of data security sharing of the Internet of Things. Background technique [0002] In real life, IoT devices will become an integral part of our society and human body (such as medical and implantable IoT devices). Data collected from a wide range of IoT devices in an IoT system can be collectively used to form intelligent operations in business, healthcare, and several other applications. For example, a basic healthcare setup includes data owners, data consumers, and various other stakeholders. Data owners can send their collective data to data consumers through some cloud services. Data users can then use these shared data to perform a series of operations. Since such data is personal data and may be sensitive, it is important to ensure the confidentiality of the data and to avoid disclosure duri...
