| Abstract(in English) | Data hiding schemes using complete complementary codes have been developed for image and audio signals. It has been shown that a high payload and a low bit-error-rate can be achieved by such data hiding strategies because of the ideal auto- and cross-correlation properties of complete complementary codes. The authors have proposed a disaster prevention broadcasting system based on the data hiding scheme using complete complementary codes. In the proposed system, detailed information on disasters such as earthquakes and tsunamis are embedded into audio signals like siren sounds. The audio signals in sirens can be processed easily by smartphones and mobile tablets for faster dissemination of disaster information in the community aiding an effective and safe evacuation. This paper shows the results of practical experiments using real siren sounds from a loud speaker. Specifically, the bit-error-rate (BER) properties are evaluated when the payload increases. The authors also propose to embed disaster information into the silent sound. It implies that no cover signal is taken into account, so it is expected that the embedded information can be extracted more precisely than those in the ordinary case where the siren sound is employed as the cover data. The BER properties in this case are also evaluated through practical experiments. |
