Yes, biometrics are generally more secure, but they aren't foolproof.
Hackers can spoof biometric data by using various techniques like downloading or printing a person's photo, using a fake silicone fingerprint, or a 3D mask.
Such attacks are known as presentation attacks..
Biometric systems can make two basic errors.
A “false positive” occurs when the system incorrectly matches an input to a non-matching template, while in a “false negative”, the system fails to detect a match between an input and a matching template..
Biometric data is digital data stored as 1s and 0s
Once saved, they can be copied into backup files and stored on servers anywhere in the world.
The risk is if access to one of the servers is compromised, these files and the biometric data they contain can be stolen and copied without anyone noticing..
There are two kinds of errors that biometric systems do: false rejection occurs when a legitimate user is rejected and false acceptance occurs when an impostor is accepted as a legitimate user..
: the measurement and analysis of unique physical or behavioral characteristics (such as fingerprint or voice patterns) especially as a means of verifying personal identity..
Among other things, Gelb said resorting to the use of multi-modal biometrics systems can reduce occurrence of errors during authentication. “The use of multi-modal biometrics can certainly reduce the rate of errors.
If fingerprints don’t work, you try iris.
If the iris doesn’t work, maybe you try face.
One of the studies we looked at does exactly t.
Gelb went further to examine the kinds of biometric error that can occur during authentication, what triggers those errors and how they manifest, as well as the consequences that come with them.
These errors, he said, can be broken down into two three main categories and they include failure to capture, false non-match or false reject rate, as well.
