Digital image manipulation software is now readily available on personal computers. It is
therefore very simple to tamper with any image and make it available to others. Insuring …

Many image watermarks have been proposed to protect intellectual property in an age
where digital images may be easily modified and perfectly reproduced. In a fragile marking …

In this paper, we present two new methods for authentication of digital images using
invertible watermarking. While virtually all watermarking schemes introduce some small …

In this paper, we present an efficient and effective digital watermarking method for image
tamper detection and recovery. Our method is efficient as it only uses simple operations …

In this paper, we introduce two techniques for self-embedding an image in itself as a means
for protecting the image content. After self-embedding, it is possible to recover portions of the …

Within the wide range of issues related to 4G wireless networks, due to the scope of the
ISSTA conference, in this presentation we highlight some segments of wireless networks …

Digital watermarking research has generally focused upon two classes of watermarks,
fragile and robust. Robust watermarks are designed to be detected even after attempts are …

This paper shows that an image can be approximately reconstructed based on the output of
a blackbox local description software such as those classically used for image indexing. Our …

Digital watermarking consists of hiding subliminal information into digital media content, also
called host data. It can be the basis of many applications, including security and media asset …

In this paper, we study the security of fragile image authentication watermarks that can
localize tampered areas. We start by comparing the goals, capabilities, and advantages of …
