This paper designs a novel underpainting based camera shooting resilient (CSR) document
watermarking algorithm for dealing with the leak source tracking problem. By applying such …

In this paper, a new Quaternion Discrete Fourier Transform (QDFT)-based digital color
image watermarking method is presented. In addition, the Quaternion QR (QQR) …

Zero-watermarking algorithms provide the means of effective, lossless copyright protection,
but the existing ones can only resist a limited variety of geometric attacks. To overcome this …

We propose a new approach for optimization in digital audio watermarking using genetic
algorithm. The watermarks are embedded into the low frequency coefficients in discrete …

Although the protection of ownership and the prevention of unauthorized manipulation of
digital images becomes an important concern, there is also a big issue of image source …

The performance of watermark detection under Compressive Sensing (CS) attack is
analyzed in the paper. Watermark is created as a pseudorandom sequence and it is …

In the field of embedding digital information or private message into an audio signal, signal-
to-noise ratio (SNR) and bit error rate (BER) are commonly performance indexes in …

The paper introduces an invisible image watermarking approach using a binary image as a
watermark in combination with the Hermite transform. By using the secret key, the binary …

Neuronal excitation enables identifying the features of an electroencephalogram (EEG)
signal for motor imagery detection. We propose a novel feature extraction algorithm …

A new audio watermarking algorithm based on Discrete Cosine Transformation (DCT)
domain is presented. Watermark embedding procedure relies on probability density function …
