Assassin is designed to be the ultimate copilot for driving in the digital world. At a basic level, Assassin operates like an extension of your dashboard, showing information like your speed, position, altitude, and other relevant information. However, it goes far beyond a typical information display. Assassin is a highly customizable platform for building the ultimate digital defense system. As you drive, Assassin interfaces with different sensors and devices to constantly attempt to detect and mitigate a plethora of modern threats to safety, security, and privacy. Assassin is capable of traffic camera alerting, and can notify the driver when approaching speed cameras, license plate cameras, red light cameras, and other traffic monitoring devices. It also supports Bluetooth tracker detection, and can alert when a Bluetooth beacon follows for a suspiciously long distance. By interfacing with an affordable ADS-B receiver, Assassin can detect aircraft, and alert to possible aerial speed enforcement. Similarly, Assassin can use a standard wireless adapter, like those found in nearly all laptops and mobile devices, to detect data transmissions from consumer drones. When paired with a graphical front-end, like V0LT Marksman, Assassin can be installed in a vehicle, then connected to from practically any device with a web browser.
