A security vulnerability in the fitness app Strava allowed suspicious figures to identify and track security personnel working at secretive bases in Israel. Information about 100 individuals who exercised at six bases was viewable. In 2018, the company published a global “heatmap” that revealed the exercise routes of people at military bases around the world. Its app takes data, including GPS co-ordinates, from a person’s mobile phone or wearable fitness device to track their exercise activity. People are able to upload their running and cycling times and compare their performances with others who followed the same routes. Is technology being used to study and control humans ?
