Challenges to Multimedia Privacy and Security Over Social Media

Abstract

With the rise in usage of social media, large quantities of data like pictures, videos, audio, and computer graphics are created. As the data is shared over the network, security and privacy become important concerns. Social networks are most popular and have become a medium for instant information sharing. Facebook, Instagram, WhatsApp are the most popular social networks. There has been extreme increase in the usage of audiovisual data over the social network. When multimedia data are stored in a networked environment, billions of users get connected to it for different purposes. The privacy challenges are personification, harassment, password sharing, location-oriented services, and privacy vs. marketing. The other challenges are data semantics, content management rights, and false information. There has been significant contribution by the researchers in development of security systems against these threats; still, the problems of clickjacking, short URL, phishing remain unresolved for some network architectures.
