#1372: ScreenKnocker

Knocking on a door in a unique temporal pattern may be used to tell the building occupants that someone they trust wants to come in.

This is hardly the security of our cyber-era -or is it?

Today’s invention is a related alternative to the conventional secure login methods for a touchscreen-enabled device.

A user touches the screen anywhere in a certain temporal sequence. The machine can detect this and decide whether to log him in or issue a refusal. Either way, the touching can be done silently and in such a way as to be very hard to shoulder surf.

One Comment:

  1. I actually think this is another Apple-type patent that they missed. You could tap in a tune involving lots of beats and do so with fingertips behind your other hand…hard to film and really very secure.
