Abstract
An apparatus and a method for preventing an information leakage. The apparatus for preventing the information leakage includes a shielding signal pattern generation unit configured to generate a shielding signal pattern including a radiation band and a radiation suppression band; a shielding signal generation unit configured to generate an electromagnetic leakage shielding signal corresponding to an Orthogonal Frequency Division Multiplexing (OFDM) scheme by using the shielding signal pattern; a signal amplification unit configured to amplify a transmitting power of the electromagnetic leakage shielding signal; and an antenna unit configured to transmit the amplified electromagnetic leakage shielding signal.
