(Background Noise) Google Will Be Able to Know Where You Are?
Google has just patented a system that can determine where you are by the background noise your cell phone provides.
You’re attending a baseball game and call Google’s 411 service for information about a nearby restaurant. The cheers of the crowd and the sounds of the announcer are picked up by your phone. Google’s system analyzes the background noise, takes into account your location, determines that you’re at a ballgame and delivers related ads or links to your phone with sports scores and news.
What if you are at a concert hall? Google provides appropriate ads.
If you have requested information, that is not a threat to your privacy. But the very fact that Google can do this tells us that others can do it, too. Technology spreads.
