Recently, multimedia and internet technologies have been in rapid development. Multimedia objects, such as images, video, audio tracks and multimedia documents, have been widely used and are in remarkable growth. Almost everyone on social network publishes or has some multimedia objects stored somewhere. Although multimedia objects are of different types, they can be treated as one entity when it comes to privacy which is our concern in this paper. Many researchers tried to apply some security on multimedia objects. In this work we aim to provide a model to protect multimedia objects from being accessed or altered by unwanted personnel.
