Content for mobile devices, unlike content for PCs, need to be optimized for the features of the mobile device. In recent years, with the progress in mobile telecom technology including Wibro and 3G, various types of mobile devices have become widely available, such as PMP, PDA, or UMPC. This has drawn attention to interactive multimedia services such as IPTV, DMB broadcasting, mobile portals and mobile TVs. However, in order to provide appropriate services for the mobile environment, the process of converting MPEG-4 BIFS to LASeR is required. This paper proposed optimized watermarking scheme for mobile device. Proposed watermarking algorithm uses z-axis location information of MPEG-4 BIFS and original model is not needed in extraction procedure. This proposed watermarking algorithm has good imperceptibility and robustness against the geometrical attacks such as noise addition, simplification and cropping. And it is proved that this proposed algorithm is good for access control capability by the experiment.
