Development of smartphone-based public vigilance systems

We present several implementations of public information collection systems. September 11th tragedy, acts of mass terrorism like DC sniper case, and suicide bombings in Europe force authorities to seek the most effective surveillance technique. It is common consensus that a common bystander does see the potentially dangerous events unwrap, and making it possible for him to notify the appropriate personal about his observations is vital to the public safety and the structural integrity of the municipal property. Cell phones are ubiquitous and most of them are equipped with a camera. The paper presents applications, both client-side and server-side, that handle the notification process. It makes it convenient and reliable.
