Face Recognition and Privacy enhancing techniques

This paper aims to clarify “face recognition” privacy issues emerging in social networks and public places. Reviewing current uses, a taxonomy of face recognition technologies is suggested to discern what aspects of face recognition impact the most on privacy, what are the main issues, and what privacy enhancing techniques are currently available to address them. Findings underline the need for a privacy-by-design approach where social computing follows evolving social norms without puncturing social context integrity.
