Biometrics authentications are good for physical security but ruin the security of password protection and generate a false sense of security in cyber space. Deployed with a fallback password against false rejection, they provide the level of security that is even poorer than a password-only authentication as illustrated in the video - Biometrics in Cyber Space - "below-one" factor authentication ( https://youtu.be/wuhB5vxKYlg ).
Elsevier's "Biometric Technology Today" has now published an article of mine titled "Biometrics: great technology for physical security, probably big mistake for cyber security?" in the May/2016 issue as announced at
The conclusion of the article is “In summary, based on this analysis, in most cases authentication by biometrics provides poorer security than pincode or password-only authentication. And given that a false sense of security is often worse than the lack of security, I would like to put forward these suggestions: the vendors of smart devices who are conscious of the privacy and security of consumers could tell consumers not to turn on the biometric functions; consumers who are concerned about their privacy and security could refrain from activating the biometric backdoors; and the deployment of biometric solutions could instead be recommended where consumers can accept ‘below-one’ factor authentication in return for better convenience.”
