A group called the Chaos Computer Club has posted a video in which they demonstrate what appears to be the ability to fool the fingerprint sensor in Apple’s new iPhone 5S. While the method is a bet convoluted, the fact is that it doesn’t involve any special technology. You just need a high-resolution picture of the fingerprint, a laser printer and some glue. Given that most of us leave our fingerprints around pretty much everywhere — including on the very phone a would-be hacker might be trying to break into — it seems like the very security the new technology is designed to provide isn’t so secure after all. But how much does that matter?
