1. A method of verifying a user presence comprising:
receiving a first signal from a sensor; determining that a user is present based on the received first signal; receiving a second signal from the sensor; determining if the user is still present based on the received second signal; determining, via a co-processor, an assertion based on a proximity vector that comprises an aggregated received first signal and received second signal; and signing the assertion to create a signed assertion, via the co-processor, the signed assertion comprising a machine specific code associated with the co-processor combined with a time stamp, the time stamp associated with a refresh rate of the sensor.
