<p>The non-linear system for digital information transmission is built on the basis of provoked signals from human electroencephalogram (EEG) and is used in the secret communication systems finding application in computer networks for the transmission and reception of digital information of high degree of security and protection. The system comprises 2N identical modules, and provisionally the first N-modules (A1, A2,... An) serve for information transmission, and the second N-modules (B1, B2,... Bn) - for its reception. The connection between each of the modules is two-way, and at every time moment each module can perform the function both of a transmitter and receiver of information. Module (A1) consists of an EEG signal, connected across analogue memory to an analogue-digital converter, the outputs of which are coupled to first buffer memory, which on its turn is connected a microcontroller, to which operative memory and second buffer memory are connected. To the second buffer memory an encoder ,to which the source of the digital signal is connected, and a decoder are connected. The personal computer is connected to the encoder, decoder and modem. The outputs of the decoder are connected to digital signal user. And the modem is connected by a connection channel to the other modules (A2,... An), (B1, B2,... Bn). 1 claim, 1 figure</p> |
