Pros and Cons of Biometric SecurityA lot has been made about biometric security over the past decade, so much so that it has been loosely integrated into many of the access control mechanisms on most modern mobile devices. Fingerprint scanners, retina scanners, and facial recognition are all part of the transition to biometrics to enhance security and privacy. For modern businesses, however, implementing biometrics can have some major drawbacks. Today, we will go over the pros and cons of biometric authentication.


For those who aren’t familiar with biometrics, it is technology that measures and analyses an individual’s physiological or behavioral traits for authentication. Physiological biometrics are things such as a person’s fingerprints, face shape, eye patterns, or hand shape. Behavioral biometrics include a person’s online behavior, the IP addresses they send and receive information from, voice recognition, and other “behaviors”.

 

The Pros of Biometric Authentication

The first thing that should be said is that biometric authentication is all about enhancing security, whether that is a fingerprint scanner to let you access a device or a state-of-the-art retina scanner to let you into a secure location in a building. As far as keeping unauthorized people out, it has to be said that biometrics work.

Biometrics Work for Security

They provide enhanced levels of security and privacy by increasing levels of assurance that the person looking for access is the person they say they are. Most accounts use passwords and PINs, and while they do offer some security benefits, biometrics present very real obstacles for hackers, scammers, and fraudsters.

Fast and Convenient

Another benefit is the sheer speed of biometric systems. They don’t take long for authentication as compared with other platforms such as pins and passwords with two-factor authentication that can take minutes rather than less-than-a-second to work. 

Very Difficult to Fake

One of the best parts of biometric authentication is that these are extremely difficult to fake and will deter all but the most savvy nefarious actors. In most cases, they will need authorization to gain access to the resources they are attempting to obtain. Period.

The Cons of Biometric Authentication

Like any technology, businesses need to weigh the pros and cons of installing biometric technology. Despite being spoof-proof for the most part and better at preventing unauthorized access, there are some negatives that biometric implementation can bring. 

Cost

To say biometrics are more costly than traditional security methods is an understatement. Even though the cost has been trending down in the last 20 years, the rate of adoption is not fast enough to make it the standard. As it is, cost is still cited as the main deterring factor to adopting biometric authentication.

Need for Security

Ironically, the most secure solution for authentication also carries the need for additional security. The biometric data that is used needs to be stored either in the cloud or in an onsite server that is secured from outside threats. If a password or a PIN is compromised then you can change it, but if biometric identifiers are compromised, they are not usable again.

Lack of Privacy

Some biometric standards actually work to eliminate or marginalize user privacy to enhance enhance security. This has long been a trade off that people have had to make, but with biometric technology, privacy is all but negated.
