Deriving multiple identifiers from multimedia content
First Claim
1. A method comprising:
- obtaining multimedia content including two or more media types, the multimedia content including first steganographic information in a first media type, the first steganographic information including first data identifying at least the multimedia content, the first steganographic information being embedded at a first encoding location; and
using a configured multi-purpose electronic processor, embedding second steganographic information in a second media type, the second steganographic information including data identifying a user or user apparatus, wherein the second steganographic information is embedded at a second encoding location that is remote from the first embedding location.

Abstract
The presently claimed invention relates generally to content identification, such as deriving identifiers from content itself. One claim recites a method including: using a processor, deriving first information from audio elements of an audio signal; using a processor, deriving second information from data representing picture elements of a video signal that is associated with the audio signal; and utilizing the first information or the second information in a content filtering process, said process utilizes a recognition unit or device to sample content being distributed on a network, and controls further distribution of the content in the network based at least in part on the first information or the second information. Of course, other combinations and claims are provided as well.
