Example

RAW DATA
The map below shows the received GPS positions of whale sharks in Australia. If these positions are publicly available in a timely manner, criminals can easily track and kill the animals. In our solution, sensitive raw data like these GPS positions stay in the secure environment of the data provider. Please select an animal on the map to display its positions.

AGGREGATED DATA
We propose to send only aggregated data to the data consumers. For instance, governments or researchers are interested in the habitat of whale sharks in Australia. The data provider receives their request, computes the habitat (convex hull of received GPS positions), and send the result to the data consumers. The sensitive GPS positions never leave the secure database of the data provider. The result is shown in the map below. Please select an animal on the map to display its habitat.
