It has been discussed a lot in the media recently whether the government should be using mobile data to monitor social distancing. Many people are concerned that such an invasion of civil liberties might not be un-done once the crisis was over. This type of video analysis provides an alternative, which is non-invasive from a privacy perspective and offers a much higher resolution on the social distancing measurement. By using edge processing, no personal data is ever generated by the system – no videos are transmitted or stored, and the AI never knows who it saw. Instead we are able simply to acquire the data that is needed to help the Government make decisions on how its lockdown policy should adapt next.
The social distancing analysis showed that by 24 March, less than 48 hours after the Prime Minister announced a lockdown, peak daily pedestrian interactions had dropped by 70%, and the morning rush our peak was no longer disenable.
