Slides from the ECU Security Research Institute seminar Monday 29 April 2013, presented by Professor Craig Valli. Our increasing interconnection networks and production of data of various types such as pictures and videos (artefacts), are producing an increasingly unseen amount of data. Metadata is data about an artefact that may, for instance, give away the location where a photo was taken, the device that created the artefact, or what operating systems and applications were used in the construction of the artefact. Furthermore, the device that transmitted the artefact may be reliably fingerprinted and identified by the applications and operating systems that it runs. Most organisations and individuals are unaware of the attendant risk that the production of artefacts with embedded metadata represents to privacy and security. This presentation will explore those risks and also demonstrate some of the capabilities of the tools publicly available to extract intelligence from metadata.
