Abstract:
The invention described herein uses a multi-touch manager for authorizing multi-touch devices by first providing a multi-touch test to a multi-touch device. In turn, the multi-touch manager receives a multi-touch response from the multi-touch device. The multi-touch manager then compares the multi-touch response with a multi-touch answer and authorizes the device based upon the comparison.
