Method, computer program product and apparatus for dynamic spatial anonymization of vehicle data in cloud environment

A method, computer program product and apparatus for dynamic spatial anonymization of vehicle data in a cloud environment. The invention relates to a method for dynamic spatial anonymization of vehicle data in a cloud environment, said method comprising:-collecting vehicle data (D (t)),-spatially dividing said vehicle data (D (t)) into data subsets (DZ (t)), the data subsets (DZ (t)) are associated with different geographic areas (Z) having different sizes and comprise a maximum record quantity (N) within each data subset (DZ (t)),-spatially aggregating the vehicle data (D (t)) within the data subsets (DZ (t)), thereby providing a two-stage aggregation:-aggregating the vehicle data (Di (t)) from a single vehicle (10) into corresponding data points (Dimean), and-aggregating data points (Dimean) from a group (G) of vehicles (10) comprising a specific number (k) of vehicles (10) into a spatially aggregated data set (Djmean). 一种用于云环境中交通工具数据的动态空间匿名化的方法、计算机程序产品和装置。本发明涉及一种用于云环境中交通工具数据的动态空间匿名化的方法，所述方法包括：-收集交通工具数据(D(t
