Google and other advertising companies have been found to be deliberately evading the privacy controls of Apple’s Safari browser. The evasion was revealed in a report in the Wall Street Journal and was based on work by Stanford researcher Jonathan Mayer. He found that the “+1” button code added to DoubleClick advertisements also allowed a Google DoubleClick tracking code to be installed on desktop Safari on 22 of the top 100 web sites. The same happened with 23 of those 100 sites when using Safari on the iPhone.

Google says the Wall Street Journal “mischaracterizes what happened and why”. According to the WSJ though, Google disabled the code after being contacted by them. While other companies found to be using the evasion technique such as Vibrant Media called it a “workaround” to make Safari “work like all the other browsers”.
