A Novel Image Authentication Approach Using an Overlap-Based Shared Secret for Collaborative Wireless Sensors
Tao Ma, Michael Hempel, Dongming Peng, Hamid Sharif · 2010
In this paper we present a novel approach that leverages overlap regions of images from different wireless sensors for mutual authentication of the transmitted images. We present our theoretical analysis for this approach and derive the authenticity ratio for a binary symmetric channel. Our results show that by selecting appropriate authenticity constraints and appropriate numbers of overlap region packets, a significant improvement of the authentication success probability can be achieved compared to traditional image authentication approaches.
