Security and Usability

Human (mis)behaviour is a key consideration in protecting IT systems. This has, however, received surprisingly little attention in research to date.


Working in an environment that cultivates interdisciplinary approaches, researchers at the HGI are charting and developing a pioneering scientific focus on the secure interplay between human beings and technology. Among other aspects, they are working on new password concepts, the secureness of CAPTCHAs and recognising “fakes” amongst online reviews.
