Wireless methods using signature codes
First Claim
Patent Images
1. A method comprising:
- receiving media content data at a device, 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 device in connection with a cryptographic operation by seeding a pseudo random number generator to identify an offset address in a noise key.

Abstract
Data representing media content, such as audio data, is processed to produce a signature code therefrom. This code can be used by wireless and other devices for a variety of purposes. Some relate to cryptographic operations. Others relate to determining whether operations involving the media content are legitimate.
