On September 29, 2022, the Sub-Committee for Intelligent and Connected Vehicles of the National Technical Committee of Auto Standardization (SAC/TC114/SC34) organized a verification test of personal information anonymization processing for the national standard Intelligent and connected vehicles (ICV) — General requirements for data (Hereinafter, referred to as the “Standard”).
The Standard is the first standard developed for vehicle data management in China. The voluntary standard puts forward the requirements for personal information and important data in its entire process of handling.
Data is one of the basic elements for ICV’s decision-making and autonomous driving, on the other hand, ICV has a huge demand for data, including vehicle data, map data, and driving environment data, etc. However, the fact that these sources of data come from diversified sources results in the problem of data being in different forms and unable to be integrated. This problem has impacted the development of the industry as well as the supervision of the government.
In this context, developing a standard to unify vehicle data is urgently needed. The standard project was therefore put forward in August 2021. It applies to Class M and N vehicles and will classify ICV data and specify the coding of each data unit so that each data element has a unique identification. The Standard, together with Intelligent and connected vehicles — General requirement of data — Part 2: Data Structure, will make up a standard series, supporting the data management of ICV.
The test first determined the speed range of the test, the position of the visual sensor mounted on the vehicle, and the method of transmitting collected data. During the test, the vehicle drove normally along the default route and enabled the functions of external information collection, recording and transmission. After the test, the vehicle data is read to calculate accuracy and false rate of the anonymization results through data frame extraction and data annotation as well as evaluate the unrecognizability and irrecoverability anonymization. The test verified the whole vehicle anonymization test solution, which was first proposed in this Standard, validating its operability and the indicators’ evaluability.
According to the standard development plan, the Standard is scheduled to be made public for comments in October and its review will be finished within 2022.
