The Web Never Forgets.
The catch is that pressure from transparency has a larger impact on the big players or publishers which are more sensitive to negative press. “A tracker which is present on a large number of sites, or is present on sites which receive more traffic is more likely to be the focus of news articles or subject to lawsuits,” said Englehardt. Smaller sites are more apt to just carry on with their tracking.
But there is a clear risk in ignoring the issue. “Without constant monitoring and transparency, level of privacy violations can easily creep back to where they were. A single, well-connected tracker can re-introduce a tracking technique to a large number of first-parties,” he warned .
Canvas fingerprinting is just one of many ways your online activities can be tracked. Notice that Englehardt said “a tracking technique” and not “the”.
While pushing for legal action against illegal data collection is one option, another more simple option you have is to block trackers from collecting information about you in the first place. Canvas fingerprinting can be blocked by some ad blockers, the Tor Onion browser, by the PrivacyBadger extension from the Electronic Frontier Foundation, and by Avira’s own Scout Browser.
In addition to having PrivacyBadger baked inside, Scout includes Avira’s own ABS extension to shut out identified trackers and malicious websites. This gives you a double-barreled approach that looks at both tracker behavior and a growing whitelist of known trackers.
If you don’t want someone painting your portrait, kick them out of the room. The choice is yours.
