Security-based excitation method with privacy protection and real-time map updating system

Abstract

The invention belongs to the technical field of vehicle map updating in the Internet of Vehicles, and discloses a safe excitation method with privacy protection and a real-time map updating system, which realize pseudonym authentication, pseudonym certificate issuing, identity tracking and reputation updating by utilizing an RSA partial blind signature technology. Reverse auction of the two parties is realized by applying a mathematical model of reverse auction and an RA algorithm; a payment system based on a blockchain technology is used to ensure secure distribution of rewards. The real-timemap updating system comprises a pseudonym management module, a reverse auction module and a reward payment module. According to the invention, the problems of payment control of a map service platform and completion quality of vehicle users are solved by applying a reverse auction algorithm; based on the RSA partial blind signature technology, the security of the excitation method is ensured, andthe privacy security problem of the user is solved; based on the blockchain technology, the problem of updating the reputation account of the user is solved, the safe distribution of rewards is ensured, and the effectiveness of the incentive method is realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle map update in the Internet of Vehicles, in particular to a security-based and privacy-protected incentive method and a real-time map update system. Background technique [0002] Currently, the closest existing technology: In recent years, with the rapid development of artificial intelligence technology, the combination of traditional automobile industry and information technology has made great progress in the research of autonomous vehicles. Self-driving cars have the potential to reduce crashes, ease traffic congestion, fundamentally change transportation systems, and provide mobility for the elderly and those with disabilities. Without a human driver, autonomous vehicles must access vast amounts of data from vehicle maps to make real-time control decisions for safety and efficiency. In the context of the rapid development of autonomous vehicles, car maps, as a supplement to existing sensors fo...

AI Technical Summary

Problems solved by technology

[0007] (1) Existing different incentive models have different incentive effects on different participant groups in different scenarios, which makes the selection and design of incentive methods complicated and difficult

[0008] (2) Existing payment control, completion quality and privacy issues are all issues that need to be addressed in the incentive method

However, the above work does not take into account the limited platform budget and limited user capabilities, so this is what we need to consider

In addition, a large amount of user data is printed on the Internet, which makes users worry about privacy being leaked, so it is necessary to achieve user's conditional privacy
