1. A method for detecting a false alarm, comprising:

  • receiving from a target for monitoring a measured value indicating a status of the target that is measured when an alarm is generated;

    measuring non-similarity between the measured value that is measured when the alarm is generated and a pre-stored normal pattern indicating normal alarm;

    measuring non-similarity between the measured value and a first statistical pattern of pre-stored measured values related to a past false alarm based on a first statistical distance between the measured value and the first statistical pattern if the non-similarity exceeds a first predetermined threshold value; and

    outputting the generated alarm if the non-similarity between the measure value and the pre-stored values related to the past false alarm exceeds a second predetermined threshold value.
