Partition clustering for GIS map data protection [PDF]
, 2014 One of the main research issues of digital data is defined by copyright protection, and digital watermarking is a potential solution to this issue. While there is an abundance of research on digital watermarking for image data, there is far less research

Information hiding through variance of the parametric orientation underlying a B-rep face [PDF]
, 2008 Watermarking technologies have been proposed for many different,types of digital media. However, to this date, no viable watermarking techniques have yet emerged for the high value B-rep (i.e.

Prikladnaya diskretnaya matematika, 2015 Summary: In order to protect both data confidentiality and legality, a concept of a watermarking cipher (also called a w-cipher) is defined. The main idea of this cjncept is as follows: the transformation of a plaintext \(x\) by the composition of encryption and decryption operations using some encryption and decryption keys yields a proper text \(x ...
