Abstract

Secure Progressively Updatable Traffic Emergency Response System (SPUTERS) is a framework for collecting traffic-surveillance data in crash-prone areas of roadways. SPUTERS receives as input video, audio, and text-based data from an integrated collection of distributed cameras and sensors, both vehicle-borne and those embedded in the roadway infrastructure. Under nominal roadway operating conditions, the multimedia data are used to develop incident countermeasures. During degraded modes of roadway operation, SPUTERS generates progressive updates to create a shared situational awareness among the people who orchestrate responses to traffic incidents and emergencies. In addition to addressing performance-oriented quality-of-service requirements for interactive display of data on Itandheld devices, SPUTERS relies on role-based access control to safeguard the privacy of roadway users under surveillance, preventing privileged information collected and managed by the system from being leaked to unauthorized persons. In order to enhance security, SPUTERS uses symmetric key encryption to guard against the unauthorized alteration of the surveillance data.
