LibeTech Uses QR Codes as Door Keys: Convenient or Dangerous?

Mobile phones are making a lot of things obsolete – payphones, maps, privacy – because of cheap and easy to use apps. A new open source technology might add keys – and keychains, and locksmiths – to the cellphone hit list. Called LibeTech, the system enables QR codes to be used as door keys.

LibeTech was developed by Jeremy Blum and 3 other students from Cornell during their senior year. The system is very simple to use. Say you have a hotel reservation. All you have to do is go to a website, log in and the hotel will send you a QR code.

When you get to your room, just show the QR code to the webcam at the door and you’re in. You don’t even need to own the latest smartphone to do this; any phone or gadget that can store and show the image of the code will suffice.

Of course, the convenience is a double-edged sword: someone could easily take a copy of your code. Imagine keys to entire hotels being shared on torrent sites. After much thought and consultation with fellow nerds, Blum and his colleagues have decided to make their technology open source instead of building a commercial product based around it. If you want to modernize your doors, head to Blum’s website for more details and links to the necessary code.
