Abstract: PURPOSE: A method for inserting and detecting a watermark by quantization of a property value of a signal is provided to calculate an insertion intensity used to transform a signal within a frame to accord the signal with a quantization value, and to transform the signal based on the calculated insertion intensity, thereby preventing an audio signal from being forged. CONSTITUTION: A device calculates a property value of a signal within a frame, which is obtained by dividing the signal to be watermarked at certain intervals(S110,S120). The device compares quantization values within a set corresponding to a value of pattern information to be inserted into the frame with the property value, among plural sets including more than one quantization value, respectively, and determines a quantization value nearest to the property value(S130). The device calculates an insertion intensity used to transform the signal within the frame to accord the property value with the determined quantization value(S140). The device transforms the signal within the frame based on the insertion intensity(S150,S160).
