Tons Of Sites, Including WhiteHouse.gov, In Unwitting AddThis Experiment With Tracking Technology That Is Difficult To Block
from the our-post-cookie-era dept
The report does note that others who have tried canvas fingerprinting have found that it's not necessarily accurate enough yet, but the technology appears to keep getting better. Still, AddThis says it's likely to drop it anyway, because it's not good enough yet:
AddThis said it rolled out the feature to a small portion of the 13 million websites on which its technology appears, but is considering ending its test soon. “It’s not uniquely identifying enough,” Harris said.The company also insisted it wasn't doing anything bad with the tracking, but even if you believe that's true, how long will it be until others make use of similar fingerprinting for more questionable behavior.
AddThis did not notify the websites on which the code was placed because “we conduct R&D projects in live environments to get the best results from testing,” according to a spokeswoman.
Given the attention this is getting, hopefully browsers will at least role out features that allow users more notification and control over such practices. Cookies are hardly a perfect solution, but at least users have control over them.
