Nope, can be fooled.
Also if someone found themselves suddenly disabled then alternative methods would have to be allowed, or else you start discriminating against those with particular disabilities.
Or it could even be not enough money to have a webcam.
As it has been said before
- disabilities can mean that alternative methods have to provided. If there is an alternative method then the biometric method is no extra security at all
- people can have an “off” day and their particular biometrics are wrong. Even Iris scanning can fail due to temporary medical conditions.
- Some people cannot purchase such biometric sensors.
- Any bio sensor can be bypassed, fooled, hacked etc. (At this time and in the foreseeable future)
- some countries do not have legal access to certain bio sensors. And some have no availability.
- Many biometrics require data to be stored elsewhere and this presents a whole new set of risks and bypassing of SAFE’s anonymity.
If one is to have this type of security then it has to mandated. If you allow an alternative method to sign on then biometrics can only a convenient alternative and not a security feature. OR else the alternative has to be so difficult that its highly likely that the person will forget vital information in order to use that alternative.
The best method for security at this time is the use of 2 nd device to confirm details. EG crypto challenge/response of some type. Even 2FA using google’s thingo.
In any case it has to be the user who decides to use an more secure login credentials, say for combating the potential of keyloggers. And the user still has to be allowed to login using an alternative method in case their out of band system is lost/broken. It is not an easy thing to fix and google solution for the person to write down the 2FA key string for the account and another device can have that 2FA key installed and used for the 2FA. Even that is not ideal because some people don’t have a smart phone and many more do not access to a 2nd deice they could use in an emergency.
