Abstract: The Internet regarded as an amorphous omnipresent space for processing and storage is called as Cloud computing. In other words Cloud Computing is defined as operations which are based on internet. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. A legal way of protecting userís data which means that data the user has created and uploaded cannot be published by anyone except the user without his permission is Multimedia copyright protection on cloud . The development of Internet has led the multimedia computing to emerge as a technology for generating, editing, processing and searching contents of media like image, audio, video, graphics and such others. Multimedia cloud computing has much challenges like Network heterogeneity, Device heterogeneity , Multimedia and service heterogeneity, Security, Power Consumption, QoS heterogeneity which has to be met. Besides this there is a big challenge for data security and access co¨ntrol when the user uploads any data in the form of multimedia content for sharing on cloud. In this paper we can see detection of copyright violation of multimedia content like images and videos. This paper proposed a new method of creating and comparing signatures of data on cloud. This paper travel through a method for enhancing security for copyright protection of multimedia content like images and videos.
