A Secure Framework for Multimedia Protection in Social Media Networks

Social networking sites usage has seen a rapid growth in recent years worldwide. Social Media Networks (SMN) such as Flickr, YouTube, and Facebook allow millions of users to share their personal information and multimedia content with relatives, friends and other online users. User information, including multimedia content, is being attacked, sold and used illegally by individuals and organizations to increase their revenue. Users are not completely aware of who has access to their private information. In this paper, we propose a new security framework for SMN that protects multimedia content against various types of attacks and illegal usage. This is achieved by using anonymous databases and Captcha implementation at the server and by using two-level user authentication with auto-locking and security+ features. The proposed security framework has been evaluated under different scenarios including human-based attacks, automated program attacks and existing security frameworks. Our evaluation shows that the proposed framework is effective in providing a secure environment for storing and sharing multimedia content in SMN.
