Embodiment Construction

[0068] In this embodiment, the process of an anonymous security forensics system for the Internet of Vehicles based on blockchain technology is as follows: figure 1 As shown, it is divided into authorization application, investigation initialization, data request, data retrieval, data analysis, result report, end of evidence collection and completion status;

[0069] Taking the vehicle digital forensics in a car networking service as an example, the data upload module is the witness who discovers an accident or crime and uploads relevant information, the data use module is the police in charge of investigation, and the authorization module is the police station and court and other authoritative departments , The blockchain module is a data storage service provided by a distributed data storage module for third parties running on a blockchain network with the authorization module as the node;

[0070] The data upload module and the data usage module are implemented on the Andro...

Abstract

The invention discloses an Internet of Vehicles anonymous security evidence obtaining method and system based on a blockchain technology. The Internet of Vehicles anonymous security evidence obtaining method and system are applied to a network environment composed of a plurality of data uploading modules, a plurality of data using modules, a plurality of authorization modules, a blockchain module and a distributed data storage module. The data uploading module preprocesses and encrypts the data, uploads the data to the distributed data storage module, and sends a corresponding transaction to the blockchain module; the data use module sets required data attributes, generates a range proof and sends the range proof to the blockchain module; the authorization module is responsible for initialization of the whole evidence obtaining system, tracing of evidence obtaining data and authorization approval operation, and participates in maintenance of blockchain nodes; the blockchain module is composed of a plurality of nodes, so that the whole system can supervise the transparency and legality of evidence obtaining; and the distributed data storage module is used for storing the encrypted evidence obtaining data and generating a downloading link. According to the invention, the confidentiality and traceability of evidence obtaining data can be protected.

Description

technical field [0001] The invention relates to a method and system for obtaining anonymous security evidence for the Internet of Vehicles based on blockchain technology, and belongs to the technical fields of Internet of Vehicles, digital evidence collection, privacy protection, and blockchain technology. Background technique [0002] In today's era, the network communication equipment, sensing equipment and other equipment equipped with intelligent vehicles have been greatly improved compared with such equipment equipped with traditional vehicles, which has made the Internet of Vehicles develop rapidly. But today, the global road traffic accidents and vehicle-related crimes have a large base. Therefore, the development of Internet of Vehicles forensics technology is of great significance to curb such accidents and crimes. [0003] However, there are potential adversaries in an Internet of Vehicles forensics system. Adversaries may illegally obtain the identities of data p...
