| WSJ: Safari loophole lets Google track Apple users through web ads Feb 17th 2012, 11:04 | Stanford researcher Jonathan Mayer has discovered a curious Safari loophole that allows Google to track a user's browsing activity via cookie-laced web ads. As it turns out, Apple's browser normally accepts cookies from sites that a user visits, but automatically blocks them from third-party advertisers. As Mayer found out, though, advertisers can still circumvent this filter by enticing users to interact with ads in different ways. In the case of Google, the search giant embedded a "+1" button on ads produced with its DoubleClick technology, as part of an opt-in feature for Google+ users. If a user was logged in to Google+ and had agreed to see +1 ad displays, he or she would have a cookie planted on their device, thanks to a system that sent invisible forms from Apple computers or iPhones. This made it seem as if a user actually submitted the form intentionally, thereby convincing Safari to allow cookies. These cookies were only temporary, with shelf lives of up to 24 hours, but they could open the door for many more, since Safari allows sites to plant them after having received access to install at least one. After the Wall Street Journal notified Google of this loophole, the company promptly disabled it and duly apologized, adding that it didn't realize that its +1 system would plant tracking cookies on a user's device. "We didn't anticipate that this would happen, and we have now started removing these advertising cookies from Safari browsers," Google's Rachel Whetstone explained. "It's important to stress that, just as on other browsers, these advertising cookies do not collect personal information." An Apple spokesperson, meanwhile, issued the following statement: "We are aware that some third parties are circumventing Safari's privacy features and we are working to put a stop to it."

Permalink |  The Wall Street Journal | Email this | Comments | | NHTSA issues "distraction guidelines" proposal for in-vehicle electronics, MyFord Touch frets Feb 17th 2012, 10:20 | With companies like Tesla and Ford replacing tactile, in-dash systems with touchscreens and gizmos, the National Highway and Transportation Safety Administration wants to set "distraction guidelines" for how automakers implement factory-installed in-car electronics. Nearly a year after discussing the possibility of bringing restrictions to in-car information, US Transportation Secretary Ray LaHood unveiled phase one of a (potential) three-part, "first-ever federal proposal" loaded with suggestions for keeping driver's eyes and attention on the road. Notably, these voluntary guidelines take aim at "communications, entertainment, information gathering and navigation devices or functions that are not required to safely operate the vehicle." According to Reuters, though, the Alliance of Auto Manufacturers claims that "elements" of the guidelines have been in practice for nearly ten years.
The ideas range from ensuring that one hand is always left free for steering and restricting the entry of text, such as an address, unless the your car is in park, to limiting in-dash text prompts to "no more than 30 characters of text unrelated to the driving task" so that your eyes can't wander off of the road for too long. Vehicles under 10,000 pounds are said to be the primary focus, with the NHTSA noting that electronic warning systems will not be under the radar as they intend to help drivers, well, drive. Before the proposal spins into action, beginning in March it will be up for public comment for 60 days L.A., Washington D.C. and Chicago. Depending on how the phase one guidelines pan out, phase two will focus on devices brought into vehicles, like cellphones, while phase three would set its sights on voice controls. If you're curious about all of the specifics, you'll find more info in the press release after the break and the full proposal draft at the source link below.
