Abstract
An electronic device is provided with an integral transducer used to update a random data pool without connection to an external source of new random data. In one embodiment, there is provided a method for providing random data on an electronic device, the method comprising: storing random data in a random data pool in a memory; sensing motion of the electronic device using a transducer integrally carried as part of the electronic device, wherein the transducer is configured to generate an output in response to sensed motion; generating new random data in accordance with the output of a transducer when sensed motion exceeds a threshold; and storing the new random data in the random data pool in the memory.
