Mobile Services and Implementation of Digital Watermarks in Audio Files

The spread of mobile devices in recent years has been dramatic to say the least. Although cell phones in particular are used by a wide demographic, and hold great potential for a variety of mobile services, the usability of their user interfaces remains lacking. Additionally, an extremely important consideration is how user interfaces handle information exchange. In this paper, a new medium of audio communication for humans and machines is discussed. We examine mobile services and the implementation of digital watermarks on music and audio files. The proposed methods allow end users to directly access relevant content or Internet sites from their music or audio, allowing users to obtain the information they seek while they enjoy their music or audio. While digital watermarking technologies have been used in the past as a security feature for copyright protection, we aim to uncover possibilities for applying this "defensive" technology as an "offensive" form of security technology that can be used in the area of mobile services.
