Abstract
The technical advancement in and the widespread expansion of use of the internet has recently led to an increase in high bandwidth multimedia data usage. This is largely due to an unfettered access to the internet. The intrinsic merit of the internet, however, brings about a side effect：multimedia date can easily be duplicated recklessly. This invokes the problem of intellectual property right violation. Focusing on this matter, multi-faceted studies are being conducted now. This paper aims to provide, by applying steganography and encryption methods into the SMIL files which supply subtitle data, the intellectual property protection of both motion picture and its subtitle data, as well as the integrity of the contents in question. In order to achieve the above goal, the authors show a particular method how to safely embed subtitle data into the given frames, after they separate subtitle data to encrypt them. By doing this, the authors suggests, the intellectual property right to the subtitle data as well as their integrity can be protected and achieved respectively. Besides, an integrity service for motion picture can be made.
