Computer-Based Copyright Control System in Social Network and An Ordinal Measure Based on Gray Scale Value
In social network, more and more video websites were appeared around the world, and everyone can upload or download the media freely. Therefore, it brings some content security problems, such as piracy, sensitive contents disclosure and so on. This paper proposes a system to detect the media which is prepare to be uploaded. First we should initialize a Media Feature Database (MFD) which contains numerous Media Features (MF) of the certi.cated media contents. When a media is preparing to be uploaded, our system will check the medias feature to make sure that whether this medias feature has already existed in the MFD. If con.ict accrued, the system will prevent the uploading. Else, the uploading will be allowed and the MFD will be updated when the uploading finished. Based on this system, this paper proposes a method of the MFs extraction- ordinal measure based on gray scale value. The experiment shows that this method is robust and efficient.
