Security informatics

Enhancing security with information technologies

Security informatics is concerned with the study of the development and use of advanced information technologies and systems for security related applications. We aim to consolidate isolated information from a variety of sources to support fast retrieval and analysis. We also design frameworks for collecting and analyzing security- and crime-related data from the Internet.
