Biometric authentication is a process of proving your identity using unique biological characteristics such as fingerprints, voice, retinal patterns, etc. This authentication technique is becoming more popular since Apple introduced a fingerprint scanner in the iPhone.
In this type of authentication, there is no need to remember any details or carry around security keys.
It's also highly secure, as it's difficult to break into a system that requires an identifier that cannot be copied or possessed.
The authentication process is done in a few seconds and requires little to no training, as the users only need to touch a scanner or click a selfie.
A biometric identifier is a parameter that can be measured to identify a person uniquely, and it serves as an access code in biometric authentication. They can be either physiological or behavioral identifiers.
Fingerprint authentication compares a user's fingerprint to the stored fingerprint templates to validate the user's identity.
Face recognition systems detect a face from a live camera source and compare it with the available database of known faces to find a match in order to complete authentication.
In retinal authentication systems, the identifier is the unique blood vessel patterns of the retina.
In this biometric, users are identified by the shape of their hand.
Body odor is a new biometric identifier that is proving to be more effective than other emerging identifiers. This identifier is still under development and not yet in use.
Voice recognition systems analyze a person's voice to validate their identity.
A person's typing pattern is unique due to neuro-physiological factors. This can be used to identify a person.
Similar to typing rhythm, the handwriting of a person can serve as an identifier, as it is distinct for each person.
As simple and secure as it sounds, biometrics do come with their own cons. For instance, since skin elasticity decreases with age, older individuals may experience difficulty authenticating themselves using their fingerprints. Worse yet, leaked biometrics could lead to compromised identities.
It's important to remember that biometrics are not 100 percent accurate. The biometric authentication system simply tries to find the best match to the given input identifier from the available collection of biometric data.
To combat these issues, there are biometric systems with modifications.
Adaptive biometric systems auto-update their biometric data with the changing environment and aging of the biometric identifiers.
Biometric system in which authentication requires more than one biometric identifier is called a multimodal biometric system. This improves the accuracy and also provides alternatives.
We already know why it's better to use biometrics in conjunction with other authentication techniques. Multi-factor authentication systems use multiple authentication methods to verify users identities. They generally include identifiers that involve:
Even though biometrics are an easy and effective security solution, we don't see widespread use of it in IT enterprises because:
ADSelfService Plus is an integrated Active Directory self-service password management and single sign-on solution that offers over 15 authentication methods for machine logon, application logon, and VPN logons. The biometric authentication methods supported by ADSelfService Plus include:
The biometric data required for verification is not stored in a central database. When the fingerprint/Face ID has to be verified, ADSelfService Plus requests the mobile phone's OS to check if the given fingerprint/Face ID matches the stored one.
There is no need to deploy and maintain a separate biometric authentication system, as ADSelfService Plus utilizes the fingerprint scanner and facial recognition system readily available in almost every smart phone. This eliminates the added costs of purchasing the required hardware, too.
Enable users to reset forgotten passwords and unlock their accounts without involving the help desk, anytime, anywhere.
Secure machine logon, application logon, and VPN logon with over 15 authentication methods that can be configured in minutes.
Sync the Windows Active Directory user password across various platforms automatically, eliminating password fatigue.
Ensure strong passwords that are equipped to fight dictionary attacks, brute-force attacks, and other password threats.
Allow users to update personal information in Active Directory, freeing the help desk from this daunting and repetitive task.
Implement single sign-on for over 300 major enterprise applications and custom applications from a single portal.
