ABSTRACT:
An electronic security device has a light-receiving interface that receives a modulated light signal emitted by the screen of a computer making use of the data medium, an output interface adapted to emit output information as a function of the received input information, and an electronic central unit connected to the receive and emit interfaces and adapted to determine the output information as a function of the input information and to cause said output information to be emitted.
