Security solutions expensively deployed for not improving security
We must look at what are NOT MENTIONED.
Firstly, biometrics that is used with a fallback password against false rejection provides the level of security lower than the password.
Secondly, physical tokens and devices that store biometrics data, cryptographic keys or passwords are as subject to loss, stealth and abuse as a memo with a password on it.
Refutations against this observation would be welcomed.
