Abstract

The presently claimed invention relates generally to digital watermarking and data hiding. One claim recites a method including: receiving data representing video, the data comprising at least first digital watermarking embedded therein; decoding the first digital watermarking embedded in the data to obtain a first identifier; and then converting the data into low bandwidth Internet video; and embedding at least the first identifier with digital watermarking into converted low bandwidth Internet video, the identifier identifying at least the video. Another claim recites a method including obtaining data representing at least video; analyzing the data to determine whether a first digital watermark is present in the data; if the first digital watermark is present in the data, embedding a second digital watermark in the data, the second digital watermark is more robust to an anticipated transformation relative to the first digital watermark; and then transforming the data according to the anticipated transformation. Of course, other combinations are described, enabled and claimed as well.

8. The method of claim 7 wherein said act of embedding the second digital watermark in the data utilizes a transform domain transformation.

9. The method of claim 7 wherein the anticipated transformation comprises low-bit rate compression.

10. The method of claim 7 wherein the first digital watermark comprises a first plural-bit message, said method further comprising decoding the first digital watermark to obtain the first plural-bit message.

12. The method of claim 10 wherein the first plural-bit message is associated with a transaction.

13. The method of claim 10 wherein the first plural-bit message identifies a data conversion.

embedding second digital watermarking in the data, the second digital watermarking being less perceptible to a human observer of the audio or video relative to the first digital watermarking; and

transforming the data to a different format, the different format comprising a relatively higher quality relative to the data when obtained.

18. The method of claim 17 wherein the first digital watermarking comprises a first plural-bit message, said method further comprising decoding the first digital watermark to obtain the first plural-bit message.

19. The method of claim 18 wherein the second digital watermarking comprises a second plural-bit message, and said act of embedding second digital watermarking in the data utilizes at least some of the bits from the first plural-bit message.
