This paper investigates the implementation of a vector-embedding scheme in video. The embedding procedure is conducted using an algorithm that is robust to standard video coding techniques such as MPEGI and II. The vector-based algorithm, using lattice codes and texture mapping for improved performance, allows large amounts of data to be stored into each frame of the video sequence. Furthermore...

In this paper, we propose a novel scheme for data hiding in the fingerprint minutiae template, which is the most popular in fingerprint recognition systems. Various strategies are proposed in data embedding in order to maintain the accuracy of fingerprint recognition as well as the undetectability of data hiding. In bits replacement based data embedding, we replace the last few bits of each ele...

Most recent papers about visual cryptography for halftone images are dedicated to get a higher contrast decoded image. However, the hidden visual pattern often blends into the background image and leads to a confused image. In this paper, we propose an improved method for halftone image hiding. By using the proposed method, the background image can be eliminated and the hidden visual pattern ca...

Digital watermarking technology has been actively studied and developed by a number of institutions and companies since mid ‘90s. This area draws more and more attention as one of the key technology elements for content management, copyright protection and copy control of digital contents. This article discusses several different types of digital watermark application, particularly the applicat...

Improved BEMD steganographic algorithm to hide secret text behind cover pixels of image to increase security of digital communication for exchanging private information worldwide using binary coefficient and modulus is proposed. From simulation results, Stego image quality better than 70dB which is higher than BEMD Kuo-Chang scheme thereby reducing mean square error difference between cover ima...

In any communication, security is the most important issue in today’s world. Lots of data security and data hiding algorithms have been developed in the last decade, which worked as motivation for the research. In the era of internet, in every communication images play a very important role. Images are used for secret communication also like for military purposes, hiding the serial number or co...

In this paper, a new methodology for the secure embedding of data in a video sequence is presented. To guarantee the imperceptibility of the embedded data, we propose a novel method for selecting the frame regions that may be considered perceptually non relevant. For each frame of the video, a saliency analysis is performed based on features that are thought to be relevant to the Human Vision S...

Medical image data hiding has strict constrains such as high imperceptibility, high capacity and high robustness. Achieving these three requirements simultaneously is highly cumbersome. Some works have been reported in the literature on data hiding, watermarking and stegnography which are suitable for telemedicine applications. None is reliable in all aspects. Electronic Patient Report (EPR) da...

An information–theoretic analysis of information hiding is presented in this paper, forming the theoretical basis for design of information–hiding systems. Information hiding is an emerging research area which encompasses applications such as copyright protection for digital media, watermarking, fingerprinting, and steganography. In these applications, information is hidden within a host data s...

An attempt is made for improvement of secret image invisibility in circulation images with dyadic wavelet based data hiding with run-length coded secret images of which location of codes are determined by random number. Through experiments, it is confirmed that secret images are almost invisible in circulation images. Also robustness of the proposed data hiding method against data compression o...
