Valuable assets are traditionally protected by secrecy, typically secret passwords. Biometric features are often readily observed and do not possess equivalent secrecy. They may also be captured with varying degrees of difficulty. This is a variation on the spoofing concern. It is certainly true that the source biometric features are not secret, but the ...

It is true that the basic biometric features cannot be changed, though in some cases, alternatives may be available (e.g. different fingers). However the simplicity of the headline argument conceals some more complex and subtle issues. We need to understand what can be compromised, examine a number of scenarios where compromise might occur and ...

Spoofing through the use of artefacts is generally a concern for physiological biometric technologies such as fingerprint, hand, iris etc. Several studies dating from around 1998 have demonstrated the potential for successfully mounting a spoofing attack under carefully controlled conditions. If spoofing attacks can be successful, the fundamental tenet of biometrics – the “something you ...
