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.

Abstract: A signal detection apparatus includes a signal reception unit, an Analog to Digital (A/D) signal processing unit, and a user interface unit. The signal reception unit receives an external signal. The A/D signal processing unit determines whether the received signal is an abnormal signal based on a plurality of signal profiles having different signal characteristics, and obtains the abnormal signal if, as a result of the determination, it is determined that the received signal is the abnormal signal. The user interface unit displays the abnormal signal.
