Watermarking Scheme for Blind Quality Assessment in Multimedia Mobile Communication Services

Due to the advancement in digital wireless communication 3rd/future generation mobile communication system expects to offer multimedia services and applications with negotiated end-to-end quality assurance. Hence devising a simple and effective billing system related to the quality of services (QoS) supplied becomes essential to the service providers. The paper proposes a low-cost spread spectrum (SS) watermarking scheme in multimedia data where the estimation of the tracing watermark at mobile station (MS) end would blindly assess the quality of services (QoS). Furthermore, the quality of tracing watermarks obtained from multipath can be used to combat the fading effect using diversity technique.
