新华网10月31日电 据美国科技博客Gizmodo报道，虽然大家都听说Facebook要升级系统，但是谁也不想要添加更多监控软件。但根据《华尔街日报》的报道，这正是Facebook在做的事情。

Facebook的分析主管Ken Rudin近日对《华尔街日报》解释了这家社交网站打算如何跟踪用户的使用习惯。简单地说，Facebook打算紧密地追踪用户使用情况。目前，该公司正在测试软件来记录用户的各种习惯，包括Newsfeed何时出现在用户的屏幕上，以及用户在页面的每一部分停留多长时间，等等等等。

也就是说，Facebook希望知道你的鼠标是怎么移动的，每一次移动都会记录。

Facebook应该不是第一个这么做的公司，但可能是最大的公司。图片网站Shutterstock就记录用户的点击，包括点击的照片，以及他们很想点击的照片。几年前，微软开发了一种方法来简化对鼠标的追踪，只需要一个很小的JS代码就可以实现。由于Facebook跟微软关系密切，Facebook的软件很可能受到了这个影响。

不过，虽然Facebook正在测试这种功能，也不意味着就一定会投入使用。“（开发）没设定结束的那一天”，Rudin说这款软件。“我不能承诺它什么时候能推出，但几个月之后也许就能知道了。”事情已经这样了，我们估计用户知道自己的隐私在这个经常侵犯隐私的网站上越来越少的时候，肯定会非常不爽。

Facebook Is Testing Software That Tracks Your Cursor's Every Move

When most people hear that Facebook upgrades are on the way, they're probably not hoping for more tracking software. But according to a new Wall Street Journal report, that's exactly what they're going to get.

Facebook's analytics chief Ken Rudin recently opened up to The Journal about how the social network plans to track user behavior. Long story short, Facebook plans to track it very closely. At the moment, the company is testing software that would record everything from when a user's Newsfeed is visible on the screen to how long a user hovers over a certain part of the page.

That's right. Facebook wants to know exactly where you're moving your mouse. At all times.

Facebook is hardly the first company to try something like this, although it might be the biggest. Stock photo site Shutterstock, for one, tracks users' every move, from the photos they click on to the photos they think about clicking on. A couple of years ago, Microsoft developed a method that made it easy to track mouse movement with a single, lightweight chunk of Javascript. Given Facebook's close relationship with Microsoft, this might have even influenced the social network's own software.

Just because Facebook is testing these kinds of capabilities doesn't mean that it's going to use them, however. "It is a never-ending phase," Rudin said of the mouse-tracking software. "I can't promise that it will roll out. We probably will know in a couple of months." Now that the cat's out of the bag, though, you can bet users are going to revolt over having even less privacy on the website known for stomping all over privacy rights. [WSJ]
