A Modified Multicarrier Modulation Binary Data Embedding in Audio File

Information hiding of data in an audio file is an important thing that the media can be recognized by its ownership. The hidden information would be the important information which describes the copyright of the audio file. In this research, the binary data is inserted or hidden into the audio file by multicarrier modulation technique data hiding. The encoded binary data is modulated by multicarrier frequencies before embedding into the host audio. Data hiding capacity with this technique can achieve up to 40 bits per second in file mode with good audio imperceptibility. It also achieves perfect robustness for type of attack noise addition, linear speed change, multi band equalization, and echo addition. And this technique is still acceptable for type of attack, such as resampling attack, MP3 compression attack and filtering attack for cut off frequency more than 10 kHz regarding to the BER less than 10%.
