Getting fingerprinted online

With this week’s focus on browsers, it seemed fitting to share Online Trackers Follow our Digital Shadow By ‘Fingerprinting’ Browsers, Devices, from NPR’s All Tech Considered.

In the interview, two Princeton researchers explain that modern-day tracking is sophisticated enough to track the “fingerprints” left by our computers and mobile phones when we go online.
