Title: Is your biometrics data safe?
Abstract:
Nowadays, biometrics is widely used in authentication systems. In general, biometrics needs to be stored in a database for subsequent authentication. However, templates stored in the database are at the risk of being stolen or modified. Once the template is stolen, it is difficult to be replaced like passwords and the private user information associated with the stolen template would also be exposed. Thus, biometrics templates should be stored in the database such that both the security of the template and the privacy of the user are not compromised under various attacks.
This talk will cover some existing techniques in dealing with biometrics data protection. A novel data hiding scheme is proposed for the thinned fingerprint template. Another new scheme is proposed to reconstruct a full fingerprint image from the minutiae points. The analysis shows that our proposed technique is useful for protecting the fingerprint ridge frequency. We also propose a novel system for protecting the privacy of the fingerprint minutiae without using a token or key.
Biography
Dr Kot has been with the Nanyang Technological University, Singapore since 1991.
