A Method, a Computer Program Product and a Device for Dynamic Spatial Anonymization of Vehicle Data in a Cloud Environment

A method for dynamic spatial anonymization of vehicle data in a cloud environment, the method comprising:

• collecting vehicle data;
• spatial partitioning of the vehicle data into data subsets, associated with different geographical areas of various sizes and comprising a maximal amount of records within each data subset;
• spatial aggregation of the vehicle data within the data subsets, providing two level aggregation:
• aggregation of vehicle data, coming from a single vehicle, to a corresponding data point;
• and
• aggregation of data points, coming from a group of vehicles comprising a particular number of vehicles, to a spatial aggregated data set.

A non-transitory storage medium comprising instructions which, when the instructions are executed by a computer, cause the computer to conduct:

• collecting vehicle data;
• spatial partitioning the vehicle data into data subsets, associated with different geographical areas of various sizes and comprising a maximal amount of records within each data subset;
• and
• spatial aggregation of the vehicle data within the data subsets, providing two level aggregation:
• aggregation of vehicle data, coming from a single vehicle, to a corresponding data point;
• and
• aggregation of data points, coming from a group of vehicles comprising a particular number of vehicles, to a spatial aggregated data set.

A device, comprising:

• memory in which program code is stored, and
• a processor configured to execute the program code, wherein executing the program code causes the processor to conduct:
• collecting vehicle data;
• spatial partitioning the vehicle data into data subsets, associated with different geographical areas of various sizes and comprising a maximal amount of records within each data subset;
• and
• spatial aggregation of the vehicle data within the data subsets, providing two level aggregation:
• aggregation of vehicle data, coming from a single vehicle, to a corresponding data point;
• and
• aggregation of data points, coming from a group of vehicles comprising a particular number of vehicles, to a spatial aggregated data set.
