This project on Aural Scramble focuses on a form of data cryptography which uses Sonic Encryption, as a form to hide Aural messages in the context of the Augmented City. This technology will allow citizens to implant encrypted audiovisual information in the City, which can be retrieved by other citizens using GPS-aware devices (e.g. smartphones). The project examines how aural and visual encryption can play an important role to determine the pace, distribution and grammar of such encoded audiovisual signifiers, within the wider context of digital humanities. Critical engagement with technology will provide strong evidences of how social network data might be implemented in the Internet of Things, raising a number of new questions about creativity but also about security and privacy.
