A social network is a social communication network which allows users to interrelate with anyone in the connected network all over the world. Users are allowed to share anything across the network like photos, videos, audios, text messages etc. , which are accessible to other users connected to the network. Now-a-days social networks have become a daily activity in everyone's life. People share everything happening in their life through social networks with their dear ones. Owing to its heavy usage, the number of contents being shared through social networks is also increasing. As a consequence, the security and rights of shared content are getting compromised. This paper aims to protect media shared through social networks against copyright infringement and a solution to overcome the copyright violation issue using watermarking method along with a comparison to the existing watermarking techniques.
