News Analysis: Google's new cookie expiration policy will do little to fortify user privacy.Google this week launched a new cookie program, aimed at appeasing privacy advocates. The search giant changed the cookies expiration date from 2038 to two years after the consumers last visit to Google. At first glance, it sounded like an accommodating change. In reality, its far from clear whether it truly gives privacy groups anything. First, giving up the 2038 date was easy, given that its highly likely the Google cookie of today (or of a few years ago) will be entirely irrelevant to the Web user of 2038. Much more importantly, though, is the practical impact today. That two-year clock doesnt start ticking until the individuals last visit to Google. If they search for anything or follow a link from anywhere that happens to land on Google, the clock starts up again. The user doesnt have to visit Google once a week or once a month. If they visit just once within two years, theyre back to square one.
