An Information-Theoretic Model for Steganography
An information-theoretic model for steganography with a passive adversary is proposed. The adversary’s task of distinguishing between an innocent cover message C and a modified message S containing hidden information is interpreted as a hypothesis testing problem. The security of a steganographic system is quantified in terms of the relative entropy (or discrimination) between the distributions...
متن کاملAn Information Theoretic Model for Database Alignment
As with many large organizations, the Government's data is split in many different ways and is collected at different times by different people. The resulting massive data heterogeneity means that government staff cannot effectively locate, share, or compare data across sources, let alone achieve computational data interoperability. The premise of our research is that it is possible to signific...
متن کاملAn Information-Theoretic Discussion of Convolutional Bottleneck Features for Robust Speech Recognition
Convolutional Neural Networks (CNNs) have been shown their performance in speech recognition systems for extracting features, and also acoustic modeling. In addition, CNNs have been used for robust speech recognition and competitive results have been reported. Convolutive Bottleneck Network (CBN) is a kind of CNNs which has a bottleneck layer among its fully connected layers. The bottleneck fea...
متن کاملDetection- and Information-theoretic Analysis of Steganography and Fingerprinting
The proliferation of multimedia and the advent of the Internet and other public networks have created many new applications of information hiding in multimedia security and forensics. This dissertation focuses on two of these application scenarios: steganography (and its counter problem, steganalysis), and fingerprinting. First, from a detection-theoretic perspective, we quantify the detectabil...
متن کاملAn Information-Theoretic Model of Voting Systems
This paper presents an information-theoretic model of a voting system, consisting of (a) definitions of the desirable qualities of integrity, privacy and verifiability, and (b) quantitative measures of how close a system is to being perfect with respect to each of the qualities. It describes the well-known trade-off between integrity and privacy in this model, and defines a concept of weak priv...
