Hello! I am a master student in the field of information security, and in nearest future I need to select theme for my thesis. I want to do a really good job, but I can not yet determine the topic.

I want to work with something associated with the analysis of public information, social networking, data analysis and things like that. Perhaps - security of web or mobile devices.

And I want to ask the community for help, maybe you can suggest interesting from your perspective directions for research.

Thank you!
