Description

Watermarking techniques, with which we can embed copyright information without degradingcontent quality, have been developed in order to track illegal copies of image or audio contents. Bydevelopment of robust embedding techniques against data compressions and analogue conversions, wecan extract embedded information just by photographing images or recording sounds from aloudspeaker with our mobile phones. These advanced technologies are expected as a noveladvertisement media. 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. Then we presentthe other types of hiding researches on embedding secondary audio signals and copy-disturbancenoises in order to protect audio contents from illegal copy actions.
