iPhone Takes Screenshots of Everything You Do

The_AV8R writes "Jonathan Zdziarski showed that every time you press the Home button on your iPhone, a screen capture is taken in order to produce a visual effect. This image is then cached and later deleted. Zdziarski says that there have been cases of law enforcement looking up sex offenders' old data and checking recovered screenshots." This revelation occurred in the midst of a webcast on iPhone forensics, demonstrating how to bypass the iPhone's password security (not trivial, but doable). Video from the talk is not online yet but is promised soon over at O'Reilly.

Errr, it's not phoning these screenshots home. You must have a problem with .bash_history too, right? Caching your keystrokes! OMG!

What's the problem

So it takes a screenshot for some effect? Is there even a way to do this without taking a screenshot? A way that is easy enough to be performed on a smartphone?

And what did you expect from Apple? That every bit of data that was discarded is overwritten ten times? Jeez, I enjoy bashing big companies as much as the other guy but now they're looking too far. Remember, it also saves your web history, every picture you took, every file you opened everything you did somewhere...
