Action-Based Trust Computation Algorithm for Online Social Network

Online Social Network (OSN) is a growing platform that enables people to get hold of news, communicate with family and old friends with whom they have lost contact, to promote a business, to invite friends to an event and to get people to collaborate. Researchers have been finding out ways to stop the negative activities over the social media by imposing the privacy settings in the leading OSNs. The privacy settings let the user to control who can access what information in his/her profile. None of these have given the entity of trust enough thought. In this research, An algorithm is proposed to evaluate and compute the Trust Factor for a user which measures the credibility of a user in the OSN world. The Trust factor considers the actions performed by the user in the OSN and the type of content being posted on the OSN, thereby, the user is responsible for his/her reputation in the OSN world. This will enable the users to decide which content is reliable and which user is credible.
