Is the compromisation of biometric features a problem?
Yes and no. Biometric features should be as unique and permanent as possible. If compromised, it is dangerous that biometric features could be misused and then, like a password, rendered unusable, except that a password is always exchangeable whereas a biometric feature isn’t. The actual danger depends upon the application and the associated precautions. No. Almost all biometric features are more or less unconcealed and therefore public (face, Finger Print , iris, voice, etc.). It is therefore a basic requirement of biometric systems’ security, that openness to the public and the subsequent ability to be compromised cannot lead to damages. If one starts with a system whose operator highly values a correct identification, the operator must make sure that the system only evaluates features that belong to the (living) person. That means: A biometric system for high-security applications cannot just compare features, instead it must also allow accurate monitoring of the source. The input o
