两种车外视频图像脱敏效果评测方法的研究

《汽车传输视频及图像脱敏技术要求与方法》(T/CAAMTB 77–2022)和“网络安全标准实践指南——车外画面局部轮廓化处理效果验证”(征求意见稿)提出了两种不同的车外视频图像脱敏效果评测方法。本文通过对比分析了两种方法在实施过程和评测效果等方面的优缺点,提出了优化建议,希望能为相关标准的制定、进一步保证智能网联汽车车端数据回传的安全性和合规性提供参考。

Based on the two different evaluation methods of desensitization effect of video images outside the car proposed in the association standard"Technical Requirements and Methods of Desensitization of video and image in Vehicle Transmission"(T/CAAMTB 77-2022)and"Practice Guide of Network Security Standards-Verification of the effect of Local contour Processing of the exterior Picture"(draft for comment),the capability was built and the actual application test was carried out respectively.The paper compares and analyzes the advantages and disadvantages of the two methods in the implementation process and evaluation effect through specific cases and hopes to promote the exploration and research of the test methods,so as to further ensure the safety and compliance of data return at the end of intelligent connected vehicles.
