A novel reversible digital watermarking technique for medical images to achieve high level
of secrecy, tamper detection, and blind recovery of the original image is proposed. The …

This article presents an information hiding algorithm for H. 264/AVC video stream. It utilizes
position of the last nonzero level of quantized discrete cosine transform block to embed …

In this study, a novel and high embedding capacity audio steganography scheme based on
Lifting Wavelet Transform (LWT) and adaptive embedding positions is proposed …

This work proposes a new and non-blind steganographic scheme for synthesized pitches.
Synthesized music is popularly used to demonstrate early versions of compositions …

In this paper, we present a novel motion vector based information hiding algorithm for H.
264/AVC against motion vector steganalysis. For resisting motion vector steganalysis, the …

The increasing rise of vulnerability of data-in-transit in the 21 st century has proven time and
again that significant emphasis must be given to improving and develo** sound …

Common application infrastructure services are shifting from back-end hosts to the network
edges. Cisco Systems application oriented networking (AON) initiative is an example of this …

In this paper, we propose a reversible watermarking scheme based on histogram shifting
(HS) to embed watermark bits into the H. 264/AVC standard videos by modifying the last …

This paper improves the speech recognition speed for the speech recognition chip
implemented on a FPGA-based embedded system by using Integer Fast Fourier Transform …

Abstract 1 This paper applies fuzzy vector quantization (FVQ) to the modeling of Discrete
Hidden Markov Model (DHMM) and then to improve the speech recognition rate for the …
