Online social network (OSN) has become an important aspect of everyone’s life. Social networking involves connecting users with their friends, relatives, family and companions. This is internet and development of other social media technologies which allow people to communicate through social media. The very well-known social sites such as Skype, Facebook, Twitter, Instagram and LinkedIn etc. enable their users for performing various activities like sharing photos, videos and information, organize events, chat, and playing online games. In this paper, a comparison study is done on various existing trust analysis techniques which will help to identify the problems need to be focused.
