PPT-Secure Communication for Signals

Paul Cuff Electrical Engineering Princeton University Secrecy Source Channel Information Theory Secrecy Source Coding Channel Coding Main Idea Secrecy for signals in distributed systems Want low distortion for the receiver and high distortion for the eavesdropper. Stochastic processes Probability theory random processes power spectral dens ity Gaussian process Modulation and encoding Basic modulation techniques and binary data transmission AM FM Pulse Modulation PCM DPCM Delta Modulation Information theory In  . Choice of secure communication protocols, leveraging SSL for remote authentication and using HTTPS for web traffic  . The rapid growth of the mobile devices as both individual and business communication devices has created a growing demand for security and privacy in this electronic communication channel. . Introduction. All creatures are capable of communicating with other members of their species. However, only the human creature has the capacity for speech. We will concentrate on the properties which differentiate human language from all other forms of signaling and which make it a unique type of communication system.. There are a lot of stories about creatures that can talk. We usually assume that they are fantasy (vision) or fiction (invented story) or that they involve birds or animals simply imitating something they have heard humans say. Rupak Kharel.

The framework is not at all restricted to medical images though and this is illustrated by applying it to multimedia sequences as well. In Chapter 4 the main results from the developments in plastic UIs and mul- modal UIs are brought together using a theoretic and conceptual perspective as a unifying approach. It is aimed at defining models useful to support UI plasticity by relying on multimodality at introducing and discussing basic principles that can drive the development of such UIs and at describing some techniques as proof-of-concept of the aforementioned models and principles. In Chapter 4 the authors introduce running examples that serve as illustration throughout the d- cussion of the use of multimodality to support plasticity.
