Abstract

The invention provides a leakage-prevention method of cloud data of Internet of Vehicles. The leakage-prevention method comprises the following steps: initializing a system: acquiring vehicle data of a vehicle by a vehicle-mounted terminal and uploading the vehicle data to a cloud server; calculating an optimal setting strategy of a Bloom filter: setting a position of the Bloom filter and needed quantity of bits and hash functions; setting the Bloom filter: carrying out network gene extraction on the vehicle data in the cloud server and setting network genes of the vehicle data in the Bloom filter; carrying out real-time detection on the vehicle data: carrying out CRC (Cyclic Redundancy Check) processing on the input vehicle data and matching a numerical value of a corresponding position of the vehicle data with the set filter; if the numerical value is matched with the set filter, immediately stopping the transmission of a data stream; and otherwise, further transmitting the data stream. According to the leakage-prevention method provided by the invention, a predicated detection result is guaranteed and memory expenditure of a whole system is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a method for preventing leakage of cloud data of the Internet of Vehicles. Background technique [0002] In the prior art, there are many network-based models to solve the data leakage problem, including: [0003] (1) Prevent the illegal theft of data inside the network by detecting whether a given keyword and data pattern appear. [0004] (2) Set up an information blacklist, use a classifier based on content similarity to detect whether the data to be accessed is consistent with the content of the blacklist, and if they are consistent, stop the data access operation. [0005] (3) On the basis of analyzing the problem that users are prone to data leakage when using cloud computing, a new anti-leakage technology is proposed. This technology mainly detects HTTP messages and can detect data diffusion between users and cloud services. , intercept and record file tr...
