Online Social Network (OSN) sites act as a medium to spread their own views, activities and their thoughts to some camaraderie. Contents of this network are spread over web, so it was hard to determine by a human decision. Currently, they do not provide any mechanism to ensure privacy concerns towards data associated with each user. Due to this problem, number of users lacks from their ownership control. In this paper, we proposed AC2P (Activity Control-Access Control Protocol) for information control on the web. Alternatively, Tag Refinement strategy determines illegal tagging over images and send notification about particular image spread within different communities/groups. These techniques reduce risk of information flow and avoid unwanted tagging toward images.
