Anonymization for Social Network Data using Multi-Party Access Control Mechanism

Abstract

Social Networking sites at present have recorded phenomenal growth rates, as they offer attractive means for digital social interactions and image sharing, but also raise a number of security and privacy issues. While Social Networks allows users to restrict access to shared content, right away they do not provide any mechanism to enforce privacy concerns over images associated with multiple users. In this paper, we present an approach for assessing the privacy risk of sharing anonymized images in network giving access to the trusted users. This leads us to show how effectively anonymization is done providing privacy for images and comments posted in public and private. To attain our approach we originate an access control model to capture the essence of multiparty authorization requirements, along with a Multi-party Access Control Mechanism. Friends in an online community designed to make social life more active and stimulating. They share images among themselves and friends comment the images, this has become the fastest growing travel and lifestyle social networking community portal and to keep your friends and family informed of your where about movements and activities. We have used the MPAC model to achieve our goal by providing anonymization for the images posted in the Social Network by individual users and also providing high level privacy for the comments below the images posted.
