There are lots of tracking protection, ad-blocking, third-party-content-filtering, and related tools for web browsers. Here's a simple way for a site to detect when a user isn't running one, and alert the user to install something:
http://ad.aloodo.com/ The general idea is: add an iframe on the page and try a tracking cookie within the iframe. If site-to-site tracking succeeds, send a message to the containing page. Any decent privacy tool should block the "tracking" here, whether it's a third-party tracking blocker such as Privacy Badger, a third-party JavaScript filter, or whatever. This version just puts up a notification, but a site might be able to use it for other things, such as * finding a logged-in company intranet user with missing tracking protection, and filing a ticket. * "reverse tracking wall": hide the content of a page, or redirect, if tracking has succeded. * add a tracking protection page to a list of recommended tips on a content site. The main point is to help ad-supported original content sites by making it harder to track their valuable audiences to less expensive sites.
