An Embedded Covert Audio Surveillance Shoe Using Application Specific Integrated Circuit ASICs

Our society today is plagued with insecurity and terrorism. The impulse to listen in on other peoples conversations is becoming more powerful as the days go by. Surveillance has changed the way we interact with one another and protect ourselves. Audio surveillance recording technology is one of the closest descendants of human spying and eavesdropping. In this paper an innovative covert audio surveillance and file keeping device implanted in a shoe is described. The recorded conversation can be retrieved by plugging the covert device in the shoe to a PC and downloading the recorded file from it through a USB cable.
