With increase in the usage of the Internet, there has been an exponential increase in the use of online social media on the Internet. Websites like Facebook, YouTube, Orkut, Twitter, Flickr, Google+, FourSquare, Pinterest, and the likes have changed the way the Internet is being used. However, widely used, there is a lack of understanding of privacy and security issues on online social media. Privacy and security of online social media need to be investigated, studied and characterized from various perspectives (computational, cultural, psychological, etc.). It is critical to detect security threats and defend privacy through real-time and scalable systems. Since there are no logical boundaries for the social media, it is important to study the problem from an international perspective too. The goals of the workshop are:

• To create a platform to discuss latest and upcoming issues, trends, and cutting-edge research approaches in security and privacy in online social media / complex networked systems.
• To bring researchers who are working separately on security and privacy, and online social media, to discuss the problems that overlap and bring these two areas together.

• PSOSM: Workshop on Privacy and Security in Online Social Media (PSOSM) (#PSOSM)
