New Kind of Door Lock
There's a new kind of door lock from the Israeli company E-Lock. It responds to sound. Instead of carrying a key, you carry a small device that makes a series of quick knocking sounds. Just touching it to the door causes the door to open; there's no keyhole. The device, called a "KnocKey," has a keypad and can be programmed to require a PIN before operation -- for even greater security.
Clever idea, but there's the usual security hyperbole:
Since there is no keyhole or contact point on the door, this unique mechanism offers a significantly higher level of security than existing technology.
More accurate would be to say that the security vulnerabilities are different than existing technology. We know a lot about the vulnerabilities of conventional locks, but we know very little about the security of this system. But don't confuse this lack of knowledge with increased security.
