1. A method of operating a first device in a system that includes two devices, one of said devices comprising a portable wireless device, the method of operating the first device comprising the acts:
- receiving media content data for rendering to a human, through a channel that includes a wireless link;
processing the received media content data to produce a signature code therefrom; and
using the signature code in the first device in connection with a cryptographic operation.
