Abstract: With the continuous expansion of the application fields of autonomous driving maps,the business models and management mechanisms for their data collection,transmission,update,and distribution are facing new transformations and challenges.On the premise of ensuring the security of geographic information,how to achieve efficient collaboration between crowdsourced collection and online update of autonomous driving map data has become a key problem that needs to be urgently solved in this field under the new situation.This paper analyzes the security and compliance requirements of crowdsourced collection and online update of map data,as well as the current state of research in this area.It proposes a safety and compliance technology for online update of autonomous driving maps that integrates the confidential processing of geographic information and commercial cryptographic protection.Through the exploration and practice of national-level scientific research project,it is verified that this technology can meet the performance requirements of related businesses of crowdsourced collection and online update,and effectively improve the security protection ability of autonomous driving maps and related geographic information data.
