Comparing Benefits of Iris Biometrics vs. Facial Biometrics for Security Authentication

Biometric access control has grown in popularity due to the convenience and security it provides for businesses and institutions. However, there are different options for biometrics, whether you’re considering fingerprint identification, iris biometrics, or facial recognition technology.

Iris biometrics and facial biometrics both provide touch-free access control solutions for facilities that require robust security that is low maintenance and doesn’t require constant cleaning. Here, we compare the benefits of iris vs. facial biometrics for security authentication.

The Similarities Between Iris and Facial Biometrics

First, let’s look at the similarities between iris and facial biometrics. Both of these technologies use a person’s individual biological features for proper identification. 

Both also provide a simplified solution for access control, as people do not need to touch a keypad or fingerprint scanner or swipe a keycard or fob to enter a building or room. These no-touch access control solutions can also help prevent the spread of germs.

Iris and facial biometrics can both be used for environments where security is paramount, such as hospitals, government institutions, and even school campuses [1].

Iris Biometrics for High Accuracy and Security

With iris biometrics, you’ll need an infrared light source and a camera to take a picture of a person’s iris. Although the hardware can be expensive, iris biometrics provide high accuracy for areas requiring strict security.

Although iris biometrics provide an effective access control solution, user-friendliness can be compromised for security. Staff needs to be trained to properly use the hardware and software, and although it works quickly, it’s generally not an ideal form of access control for areas with high traffic. In addition, people who have had cataract surgery may not be able to use the scanner or may need to be re-entered into the system.

Irises are unique to each person—each iris contains 240 recognition points, which is more than a fingerprint or a face provides [2]. For institutions that require high accuracy and security, iris biometrics may be a viable option.

Facial Biometrics for Convenience and a Lower Cost

Facial biometrics are generally more convenient than iris scanners as they are non-intrusive and don’t require infrared lighting. However, they do require adequate lighting, and a person would need to look at the camera in order for the technology to be utilized [3].

Some companies prefer facial biometrics because they can essentially replace iris and fingerprint scanners, allowing for a more efficient form of security without the need for expensive hardware and maintenance.

In addition, facial recognition technology can be utilized as a form of access control instead of an app, keycard, or PIN. This allows businesses to capture faces for a database where approved personnel are automatically granted access while unrecognized or unreadable faces are denied.
