An international governmental mailing system : a requirement to prevent web-enhanced terrorism

Abstract

E-mail systems are essential, but they also provide terrorists with an opportunity to impersonate public officials and, with the legitimacy and authority of the alleged sender, obtain collaborations or spread misinformation in critical situations, where the urgent need to responses relegates identity confirmations to a lower priority. This paper presents an e-mail system architecture that uses Public Key Infrastructures and behavioural biometrics to guarantee that only their legitimate users use governmental domains, automatically confirm their identity and encript/decript messages exchanged between public officers. The biometric components of the system can also contribute to a distributed database destined to identify anonymous e-mail senders.
