Study: Online Trackers Follow Health Site Visitors
June 24, 2020
Internet trackers are more likely to follow people who visit popular health sites, such as WebMD.com and mayoclinic.org, to other types of sites, a Cornell Tech study has found – suggesting that advertisers might be more likely to target people based on sensitive health information than previously understood.
The study was led by Helen Nissenbaum, an Einaudi faculty member, and Ido Sivan-Sevilla.
