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. |

... given that the exact form of a copyright notice holds such legal significance, a copyright notice in a watermark probably would not suffice as an alternative to including the standard “cс” notice. However, the system does make it easier ...
... given copy. The owner, of course, should still have an unwatermarked version of the Work and can thus provide it to the detector along with the illegal copy. This often substantially improves detector performance, in that the original ...
