This paper reviews the state of the art in visual privacy protection techniques, with particular
attention paid to techniques applicable to the field of Active and Assisted Living (AAL). A …

We consider the problem of embedding one signal (eg, a digital watermark), within another"
host" signal to form a third," composite" signal. The embedding is designed to achieve …

In this paper, we propose a self-synchronization algorithm for audio watermarking to
facilitate assured audio data transmission. The synchronization codes are embedded into …

This paper presents two vector watermarking schemes that are based on the use of complex
and quaternion Fourier transforms and demonstrates, for the first time, how to embed …

This paper deals with data hiding in compressed video. Unlike data hiding in images and
raw video which operates on the images themselves in the spatial or transformed domain …

Digital image watermarking has justified its suitability for copyright protection and copy
control of digital images. In the past years, various watermarking schemes were proposed to …

Linking network flows is an important problem in intrusion detection as well as anonymity.
Passive traffic analysis can link flows but requires long periods of observation to reduce …

In this paper a new adaptive audio watermarking algorithm based on Empirical Mode
Decomposition (EMD) is introduced. The audio signal is divided into frames and each one is …

Deterministic perception of the surrounding environment is both crucial and a challenging
task for autonomous vehicles. A wide range of sensors, including LiDAR, RADAR, cameras …

Traditional quantization index modulation (QIM) methods are based on a fixed quantization
step size, which may lead to poor fidelity in some areas of the content. A more serious …
