CAAM: Blockchain for data exchange between cars

2021: Chinese automakers will use blockchain to transfer data between machines

In early May 2021, the Chinese Association of Automakers (CAAM) held a congress on the protection of connected car data. During the discussion, automakers agreed to use a new blockchain-based solution that can ensure traceability and security of data transfer between cars.

The Chinese Association of Automakers invited 32 companies related to the development of smart and connected cars to the congress. Among the international manufacturers were Tesla, Volkswagen, Daimler, BMW, Audi and Geely (owned by Volvo), as well as Bosch and the German Association of Automakers. Representatives of FAW, SAIC, Changa, Dongfen, BAIC, GAC, Great Wall, Chery, Weilai, Idea, Xiapeng, China Auto Chuangzhi, Shanghai Auto Inspection, NavInfo, Energy and Technology arrived from China.

In addition, a number of Chinese government departments were present, including the Ministry of Industry and Information Technology, the Ministry of Public Security, the Institute of Information and Communication Technologies and the National Platform for Monitoring and Driving Vehicles Using New Energy Sources.

Most of the congress was devoted to the problems of data security of connected cars. One of the problems impeding the development of the industry is the huge amount of data produced. The other is a data privacy issue. Among other things, the question arose whether the Chinese government would require access to data on cars produced by Western brands. If companies provide access to sensitive data, this could affect brand perceptions in the West. However, the Government and law enforcement agencies may need this information to investigate accidents or criminal cases.^[1]
