Social Networks and Big Data have pervaded all aspects of our daily lives. With their unparalleled popularity, social networks have evolved from the platforms for social communication and news dissemination, to indispensable tools for professional networking, social recommendations, marketing, and online content distribution. Social Networks, together with other activities, produce Big Data that is beyond the ability of commonly used computer software and hardware tools to capture, manage, and process within a tolerable elapsed time. It has been widely recognised that security and privacy are the critical challenges for Social Networks and Big Data applications due to their scale, complexity and heterogeneity.

The 3rd IEEE International Symposium on Security and Privacy in Social Networks and Big Data (IEEE SocialSec 2017) will be held in Melbourne, Australia on 13-15 December 2017. It follows the success of SocialSec 2015 in Hangzhou, China and SocialSec 2016 in Fiji. The aim of the symposium is to provide a leading edge forum to foster interactions between researchers and developers with the security and privacy communities in Social Networks and Big Data, and to give attendees an opportunity to interact with experts in academia, industry, and governments.

SocialSec 2017 will be co-located with the 13th International Conference on Information Security Practice and Experience (ISPEC 2017).
