If you think watching pornography in the “incognito” mode will not let anyone know, you are mistaken. Google, Facebook and even Oracle cloud are secretly tracking the porn you watch even when you switch on the “incognito” mode on your laptop or smartphone, NDTV reported.
A new joint study from Microsoft, Carnegie Mellon University and University of Pennsylvania that investigated 22,484 porn websites using a tool called “webXray” revealed that 93 per cent of pages track and leak users’ data to third-party organisations.
“Tracking on these sites is highly concentrated by a handful of major companies,” said the researchers, who identified 230 different companies and services tracking users in their sample.
Among non-pornography-specific services, Google tracks 74 per cent of pornographic sites, Oracle 24 per cent, and Facebook 10 per cent.
Porn-specific trackers in the top 10 are exoClick (40 per cent), JuicyAds (11 per cent), and EroAdvertising (9 per cent).
“The majority of non-pornography companies in the top 10 are based in the US, while the majority of pornography-specific companies are based in Europe,” said the study.
The researchers—Elena Maris, Microsoft Research; Timothy Libert, Carnegie Mellon University; and Jennifer Henrichsen, University of Pennsylvania—said they successfully extracted privacy policies for 3,856 sites, 17 per cent of the total.
“The policies were written such that one might need a two-year college education to understand them. The content analysis indicated 44.97 per cent of them expose or suggest a specific gender/sexual identity or interest likely to be linked to the user,” said the study to be published in the journal New Media & Society.
