Certification of Secure Encounter History Among Low Power Mobile Sensors

In this paper, we propose a technique for certifying encounter information with acquaintances in wireless sensor networks. In our technique, we assume that each user holds a small low power sensor with a short range wireless communication device such as ZigBee, and that multiple sensors called landmarks, which provide accurate location and time, are sparsely distributed in the target area. Each...

A Support Vector Machine (SVM ) is a powerful classifier method, already used in many problems, which can be viewed as a learning problem bringing to a convex optimization. In recent years, a considerable attention has been given on semisupervised learning, differing from traditional supervised learning by making use of unlabeled data. In fact, in many applications, labeling examples may cost l...
