OP's question compares the same with traditional password - hence traditional password schemes are less probable & have lesser exposure to threat surfaces than the prior Biometric Security Mechanisms. Using more compliant keeping the traditional passwords & biometric optional post prior login methods have been successful - might be the take-away.
I'm a beginner to security, and I had a question about biometric match thresholds. Does a higher threshold signify that the system follows a strict(er) policy? Also, suppose I have a threshold of 0.5; does it mean that the sample must be at least a 50% match of the reference template? How exactly is a threshold calculated?
In general, the performance of any biometric system (e.g fingerprint, voice, facial recognition, etc) is described using several metrics. FAR or False Acceptance rate is the probability that the system incorrectly authorizes a non-authorized person, due to incorrectly matching the biometric input with a template. The FAR is normally expressed ...
Even if we use FRR and FAR to determine a global threshold for a specific biometric, and if any template from same biometric when matched either under 1:1 or 1:n scenario has similarity above that threshold or distance below that global threshold will be accepted either its cat/dog face. –
A false negative is when biometric systems fail to recognize an authentic individual, which would lead to something not happening. Depending on what that something is there could be various consequences: Personal: An owner of a safe may be prevented from accessing that safe, leading to him/her being unable to access a necessary resource.
Today biometric security checks like fingerprint scanners and face recognition are often promoted as good security measures, but let’s say that a database of face scans is stolen. People can’t get a new face. Is Face ID now unusable for all those affected, or is there some additional security measures that make Face ID usable as a login method?
Modern security is based on 3 principles: Confidentiality, Integrity, and Availability. Biometric authentication on it's own while it is great on availability, it violates the other two principles. First we will discuss confidentiality. Your fingerprints are not a secret. Everything you touch leaves them behind.
Security best practices these days (like the CISSP certification's baseline for security practices) don't point towards Biometrics being the end-all, be-all for security. The best practice is to build a system with a collection of authentication mechanisms that are appropriate for the system, the information in it, the expected threats and ...
Biometric eye scan; Security badge; Smart card and PIN; Encrypted login and password; The answer at the end of the chapter was: For high-security installations, biometrics is an extremely secure method to authenticate users based on unique physical characteristics. My question is. How is it possible the answer was not number 3?
Keep this distinction in mind: even though most face recognition systems can match two photos of faces, biometrics is specifically about matching a human. HR or IT security or whoever it is has to check two things: You look like the photo, and you're a human. Likewise, every non-quack biometric authentication system has to check these two things.
