Data must not only be anonymized and aggregated, but also secured with techniques like on-device encryption and tamper-proof hardware security keys.
For these reasons, we limit ourselves here to the following proof-of-concept: We show results of the application of our method in which we aggregate events to the level of the country, we aggregate over motives for the protest, and we aggregate events to the weekly scale, i.e. the timestep in our method is one week.
