However, as illegal copy actions cannot be suppressed by a watermarkingtechnique itself, researches on embedding copy-disturbance noises have also begun. The embeddedcopy-disturbance noises can be visible or audible by giving the content some changes such as analogueconversion with copy actions, and we can suppress distribution of illegally copied products. In thispaper, we will overview fundamental information hiding techniques for audio signals.
