Partition clustering for GIS map data protection [PDF]
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]
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.

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 ...

Robust Backward Model Watermarking Method Based on Backdoor [PDF]
The training cost of deep learning model is high; however, the stealing cost is low. This model is easy to copy and spread. The copyright owner of a model can embed a watermark in the model using a backdoor or another method.

A contrast-sensitive reversible visible image watermarking technique [PDF]
A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

Reversible watermarking scheme with image-independent embedding capacity [PDF]
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,
