15. The computer readable medium of claim 4, wherein analyzing the data representing audio elements or image picture elements to extract identifying information therefrom comprises decoding steganographically hidden information.

16. The computer readable medium of claim 4, wherein the control information comprises copy control information.

17. The computer readable medium of claim 4, wherein the data represents audio elements and the sensor comprises a microphone.

18. The computer readable medium of claim 4, wherein the data represents image picture elements and the sensor comprises a camera.

8. An apparatus comprising:

a memory configured to buffer data representing audio elements or image picture elements, wherein the audio elements or image picture elements are captured with a sensor;

a processor configured to;

analyze the buffered data representing audio elements or image picture elements to extract identifying information therefrom;

control communication of extracted identifying information to a database;

control receipt of control information from the database; and

initiate an action based at least in part on the control information.

9. The apparatus of claim 8, wherein the image picture elements comprise video.

10. The apparatus of claim 8, wherein analyzing the data representing audio elements or image picture elements to extract identifying information therefrom comprises decoding steganographically hidden information.

11. The apparatus of claim 8, wherein the control information comprises copy control information.
