In this paper we discuss about stream integrity problem and specifically we propose a method to protect a live video stream against forgery. In particular we propose to use cryptographic techniques to provide integrity and source identity embedding in the source stream a hash chain built on the top of each frame as produced by the source. We first present a real life scenario in which stream integrity could be considered an enabler, then we describe our method to perform real time integrity check. In last section an implementation is sketched to show main implementation parameter.

Abstract
In this paper we discuss about stream integrity problem and specifically we propose a method to protect a live video stream against forgery. In particular we propose to use cryptographic techniques to provide integrity and source identity embedding in the source stream a hash chain built on the top of each frame as produced by the source. We first present a real life scenario in which stream integrity could be considered an enabler, then we describe our method to perform real time integrity check. In last section an implementation is sketched to show main implementation parameter.File in questo prodotto:
