Digital WatermarkingElsevier, 2001. gada 17. okt. - 542 lappuses Digital watermarking is a key ingredient to copyright protection. It provides a solution to illegal copying of digital material and has many other useful applications such as broadcast monitoring and the recording of electronic transactions. Now, for the first time, there is a book that focuses exclusively on this exciting technology. Digital Watermarking covers the crucial research findings in the field: it explains the principles underlying digital watermarking technologies, describes the requirements that have given rise to them, and discusses the diverse ends to which these technologies are being applied. As a result, additional groundwork is laid for future developments in this field, helping the reader understand and anticipate new approaches and applications. |

... quantization step size. Each quantized coefficient encodes either a 0, if it is quantized to an even multiple, or a 1, if quantized to an odd multiple. The pattern of 1s and 0s embedded depends on a key that is shared with the detector ...
... quantization usually does not affect the relative magnitudes of different values, most bits of this signature should be unaffected by JPEG (which quantizes images in the block DCT domain). The signature is embedded in the highfrequency ...
... quantization applied by most lossy compression algorithms can leave telltale statistical changes in a watermark that might be recognizable. The call for proposals for Phase II of SDMI required this functionality in an audio watermark ...
