PURPOSE: A computer security system using an RFID(Radio Frequency ID) card is provided to prevent the interception of important data in a computer by enabling only a specific user to use the computer based on the RFID card. CONSTITUTION: An RFID card(102) is carried by a user and transmits an encoded frequency. A frequency receiving unit(106) receives and decodes the encoded frequency. A control unit(108) receives a password of the RFID card decoded in the frequency receiving unit, compares the password of the RFID card with a password of a registered RFID card according to a set program, and transmits a control signal controlling the turn on-off of a monitor and the locking/unlocking of a keyboard. A keyboard locking/unlocking switch(112) locks or unlocks the keyboard according to the control signal. A monitor turn on-off switch(116) turns on or off the monitor according to the control signal.
