An Android developer recently discovered a clandestine application called Carrier IQ built into most smartphones that doesn't just track your location; it secretly records your keystrokes, and there's nothing you can do about it. Is it time to put on a tinfoil hat? That depends on how you feel about privacy.

The reason for this invasive Android app seems reasonable enough at face value. Even though it's on most Android, BlackBerry and Nokia devices, most users would never know that Carrier IQ is running in the background, and that's sort of the point. Described on the company's website as software to gain "unprecedented insight into their customers' mobile experience," Carrier IQ is ostensibly supposed to help mobile carriers and device manufacturers gather data in order to improve their products.
Tons of applications do this, and you're probably used to those boxes that pops up on your screen and ask if you want to help the company by sending your data back to them. If you're concerned about your privacy, you just tap no and go about your merry computing way. As security-conscious Android developer Trevor Eckhart realized, however, Carrier IQ does not give you this option, and unless you were code-savvy and looking for it, you'd never know it was there. And based on how aggressive the company has been in trying to keep Eckhart quiet about his discovery, it seems like Carrier IQ doesn't want you to know it's there either.
