Abstract
The present disclosure relates generally to encoding and decoding signals from media signals. One claim recites an apparatus comprising: electronic memory for storing blocks of a media signal; an electronic processor programmed for: determining a detection metric for the blocks, the detection metric comprising a measure of coincidence of detection parameters of different blocks; and performing detection operations based on the measure of coincidence of the detection parameters. Of course, other claims and combinations are provided as well.

8. A method comprising:
-
receiving information for embedding in a media signal; using an electronic processor programmed as an encryption unit, encrypting the information to form an encrypted signal, the encrypted signal comprising elements that correspond to attributes of the media signal; and using an electronic processor programmed as an encoding unit, encoding the encrypted signal in the media signal, in which said act of encoding includes quantizing attributes of the media signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method comprising:
-
using a programmed electronic processor programmed, generating first and second decoding signals using first and second encryption keys, respectively, the first and second decoding signal are for extracting an encoded message from a digital watermark encoded in a media signal; using a programmed electronic processor, extracting estimates of the encoded message using the first and second decoding signals; and determining whether the estimates are valid using error detection. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
