In a story today by Julia Angwin and Jennifer Valentino-Devries, the WSJ
said:
[Google and others] used special computer code that tricks Apple's
Safari Web-browsing software into letting them monitor many users. Safari,
the most widely used browser on mobile devices, is designed to block such
tracking by default.
In a separate blog post, Valentino-Devries explains:
By default, Apple's Safari browser accepts cookies only from sites that
a user visits; these cookies can help the site retain logins or other
information. Safari generally blocks cookies that come from elsewhere –
such as advertising networks or other trackers. But there are exceptions to
this rule, including that if you interact with an advertisement or form in
certain ways, it's allowed to set a cookie even if you aren't technically
visiting the site.
Google's code, which was placed on certain ads that used the company's
DoubleClick ad technology and was uncovered by Stanford researcher Jonathan
Mayer, took advantage of this loophole, as did the code used by the other
companies.
Ryan Gavin, Microsoft's General Manager, Internet Explorer Business and
Marketing, couldn't resist getting in a dig of his own against Google for
the fiasco, as well as casting a less-than-subtle aspersion at Apple and its
browser:
This type of tracking by Google is not new. The novelty here is that
Google apparently circumvented the privacy protections built into Apple's
Safari browser in a deliberate, and ultimately, successful fashion.
If you find this type of behavior alarming and want to protect your
confidential information and privacy while you're online, there are
alternatives for you. Windows Internet Explorer is the browser that respects
your privacy.
Rachel Whetstone, Google's senior vice president for communications, offered
NPR this explanation, saying the Journal story "mischaracterises what
happened and why."
We used known Safari functionality to provide features that signed-in
Google users had enabled. It's important to stress that these advertising
cookies do not collect personal information.
Unlike other major browsers, Apple's Safari browser blocks third-party
cookies by default. However, Safari enables many web features for its users
that rely on third parties and third-party cookies, such as "Like" buttons.
Last year, we began using this functionality to enable features for signed-
in Google users on Safari who had opted to see personalized ads and other
content—such as the ability to "+1" things that interest them.
To enable these features, we created a temporary communication link
between Safari browsers and Google's servers, so that we could ascertain
whether Safari users were also signed into Google, and had opted for this
type of personalization. But we designed this so that the information
passing between the user's Safari browser and Google's servers was anonymous
—effectively creating a barrier between their personal information and the
web content they browse.
However, the Safari browser contained functionality that then enabled
other Google advertising cookies to be set on the browser. We didn't
anticipate that this would happen, and we have now started removing these
advertising cookies from Safari browsers.
