Problems solved by technology

[0003] With the rapid development of the Internet of Vehicles, more and more vehicles are involved in collecting and uploading nearby traffic conditions, and the data capacity is getting larger and larger, which may generate more duplicate data, which will bring unnecessary communication overhead and waste unnecessary storage
In the current field of Internet of Vehicles, the deduplication technology of duplicate data is mainly based on the content comparison of data, so as to realize the deduplication of the same data content, which is inefficient to implement, and the deduplication results of duplicate data are low in efficiency and poor in accuracy. No effective solution has been proposed yet

Abstract

The invention discloses a traffic data de-duplication acquisition method. The method uses the Bloom filter and the property of convergent encryption to perform repetitive detection and query on the data uploaded by vehicles. The combination of the two technologies can effectively detect and delete traffic data duplication. , to easily realize data duplication detection, and at the same time ensure data privacy.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for deduplication and acquisition of traffic data. Background technique [0002] The Internet of Vehicles is the application of Internet of Things technology in the field of transportation systems, and it is also an important part of the next generation of mobile Internet. The Internet of Vehicles system includes three participants: the on-board unit OBU deployed on the vehicle, the roadside unit RSU fixed on both sides of the road, and the trusted agency TA. In the Internet of Vehicles, the highly intelligent OBU can link with the urban traffic information network, smart grid, and community information network according to its own conditions, and obtain instant information anytime and anywhere, thereby avoiding traffic accidents or road congestion, and improving driving efficiency and safety. . [0003] With the rapid development of the Internet of Vehi...
