Imagine being able to complete a purchase at your local grocery store simply by swiping your phone past the point-of-sale terminal without any fear that the credit card information sent from your phone to the terminal is being snooped or hacked.

Based upon our patented high-value distance-measuring technology, we have invented an algorithm for generating a sequence of identical secret key bits at two electronic devices simultaneously that can be used to encrypt digital communications between the devices.  To initiate the key generation process, the user simply swipes the handset across the front face of the POS terminal, during which time both the terminal and the handset measure the distance between the devices independently, accurately, and in real time.  At the end of the swipe both devices have independently computed identical keys which are then used to encrypt and decrypt the credit card information sent from the handset to the terminal.  Just as no two snowflakes are alike, no two swipes are alike, and the unique swipe profile yields a unique and measurably random sequence of 128 bits.  Importantly, no key data of any kind has been sent or received to/from either device.

The encryption technology is also suitable for applications other than purchases as well.  Other uses include:
Keyless entry (homes, cars, secure facilities, etc.)
Alarm enabling or disabling
Accessing secure data (wireless USB, medical tags, ID tags)

A paper that describes an optical implementation of this technology is available here, and is described in greater detail in our US patent application, 20090052663, Methods for creating secret keys based upon one or more shared characteristics and systems thereof.

A second patent application has been filed that covers a Bluetooth embodiment.  Please contact us directly for a copy of a paper that describes this implementation.

We are currently seeking a qualified partner that can accelerate the development process and aggressively commercialize the technology.
