Upgrading Existing Biometric Security Systems by Implementing the Concept of Cancelable Biometrics
Marko Antonic · 2008
Today's biometric security systems have a number of problems that emerge from the fact that the biometric data of a person is stored in the system. The problems arise when that data is compromised. Standard password based security systems have the ability to cancel the compromised password and reissue a new one. The biometrics cannot be canceled or changed which can be their advantage and a disadvantage in this particular situation. The concept of cancelable biometrics can upgrade the biometric security system so that it gains the advantages of the password based security system, by not losing the inherent superiority.
