"All war is deception", this according to Sun Tzu's The Art of War. An inventor from Indiana, Anthony Dewayne Johnson, recently published a patent application that takes this teaching to heart, US20190033781A1 Special holographic security systems and similar holographic defense systems. Saving lives and improving the effectiveness of home, commercial and military security systems is the primary goal of Johnson's 2019 application.
The home and commercial applications are designed to augment existing security systems. In addition to monitoring an area and communicating with law enforcement, the holographic security system provides visual and audio warnings. Pre-programmed images and sounds can be presented to frighten intruders, such as the resident, a security guard or a barking dog. In addition, the representations can be linked to remote devices, like a smartphone, and provide real-time communication with the threat, i.e., "I've called the police" or "Do you feel lucky? Well, do you, punk?"
