Lest you think the recent high-profile info leak cases are unique, new research finds that many popular websites leak your information to third parties — often on purpose.
And, while each website might be leaking only a small portion of your information, the powerful tracking tools that receive it are able to patch all those small tidbits together into a pretty clear picture of who you are and what you are interested in. That’s the finding of a study of more than 100 popular websites used by tens of millions of people that found three-quarters directly leak either private information or users’ unique identifiers to third-party tracking sites, according to research co-author Craig Wills, professor of computer science at Worcester Polytechnic Institute (WPI).
