Abstract:
Early information distribution in crisis events constitutes an important life-saving and social security characteristic. Modern information technologies can provide the possibility of developing systems which can timely send warning messages to citizens within a specific area in order to protect them from a crisis event that occurs in a close region. The current paper attempts to design a new system model aimed to be utilized for warning citizens outside a building about criminal activity in the inner part, within a target area, and prevent them from entering inside. Basic parts of the proposed early-warning system are the RADIO-HELP system enriched by an algorithmic message encryption/decryption process. Combination of these methodologies forms the proposed contribution. People inside the building shall receive by the Police Operational Center encrypted message so that no panic situation will occur and no escape effort will be made by criminals; on the other hand citizens outside the building shall receive clear decrypted message. The message type (encrypted or decrypted) is dependent on the geographic definition of the target area.
