- Digital watermarking is one part of the data security techniques that is beginning to be developed now. This is a technique of hiding data a host file into other data files by using the weaknesses of human senses, such as the eyes at the image processing and ears at audio processing. This research aims to produce MP3 audio files with watermark (text file) that can be used for copyright protection, reliable and resilient digital signal processing. Digital watermarking techniques that used in this study is the phase of engineering techniques in audio signals, known as Phase Coding. In this study, the applications mades by Visual Borland Delphi 7. Copyright protection in audio by Watermarking-Phase Coding produces resistant audio digital to signal processing without destroying the audio and text files that have been inserted and has a small difference phase between the original signal and the signal that modified, so the difference in the sound produced is not detectable by human hearing . When the watermark is less detected, then security level will getting better.
