Ingemar J Cox, Joseph J Kilian, Talal G Shamoon: Secure spread spectrum watermarking for multimedia data. NEC Research Institute, Philip J Feig, July 27, 1999: US05930369 (526 worldwide citation)

Digital watermarking of audio, image, video or multimedia data is achieved by inserting the watermark into the perceptually significant components of a decomposition of the data in a manner so as to be visually imperceptible. In a preferred method, a frequency spectral image of the data, preferably ...

Ingemar J Cox: Spread spectrum watermark for embedded signalling. NEC Research Institute, Philip J Feig, December 8, 1998: US05848155 (357 worldwide citation)

A watermark is embedded into audio/video/image/multimedia data using spread spectrum methodology. The watermark is extracted from watermarked data without the use of an original or unwatermarked version of the data by using spatial or temporal local averaging of the frequency coefficients of the wat ...

Ingemar J Cox: Watermarking of image data using MPEG/JPEG coefficients. NEC Research Institute, Philip J Feig, Jeffery J Brosemer, May 30, 2000: US06069914 (213 worldwide citation)

A watermark is embedded into video/image/multimedia data using spread spectrum methodology. The watermark is extracted from watermarked data without the use of an original or unwatermarked version of the data by using MPEG/JPEG coefficients. The image to be watermarked is divided into subimages. Eac ...

Ingemar J Cox, Matthew L Miller, Ryoma Oami: Robust digital watermarking. NEC Research Institute, NEC Corporation, Philip J Feig, November 28, 2000: US06154571 (211 worldwide citation)

A watermarking procedure that is applicable to images, audio, video and multimedia data to be watermarked divides the data to be watermarked into a set of n.times.n blocks, such as the 8.times.8 blocks of MPEG. The same watermark signal can be distributed throughout the set of blocks in a large vari ...
