Hackers can steal your email and password — but they can’t steal your face. 

Facial recognition technology, a rapidly evolving aspect of biometric authentication, has become a staple in digital security for exactly this reason. It uses advanced algorithms and artificial intelligence (AI) to identify and verify you based on your facial features. 

Here’s a guide to what facial recognition is and its applications in real life.

What is facial recognition?

Facial recognition, or face recognition, is a type of biometric security that uses your unique facial features to identify or confirm your identity. This technology works alongside other biometric methods like voice, fingerprint, and eye recognition, though it’s increasingly more common because of its ease of use. 

Facial recognition systems are great for more than just logging into your phone. They can pick out faces in photos, videos, and even in real-time scenarios. Facebook can tell if you’re in a photo just by your facial features, and security cameras can spot previous shoplifters and criminals when they enter a store.

How does facial recognition work?

Picture a friend or family member in your head. They have specific facial features — down to the very last millimeter — that make them different from anyone else in the world. A face analyzer’s job is to pinpoint those unique features, with details ranging from the distance between the eyes to the shape of the jawline. 

But for the facial recognition system to work, it needs to have a database of faces to compare this information with. The goal is to match what the system sees to an existing face. Otherwise, the data it collects from photos and videos is meaningless.

Once a facial recognition system connects to a database, it scans either photos, videos, or real-time feeds to identify faces. It collects data about the size, shape, and relationships between different features and compares them to existing faces — hopefully finding a match. The catch is that people look similar, and the system might not be 100% accurate all the time.

What are the uses of facial recognition technology?

Facial recognition technology plays a key role in security, travel, and healthcare, just to name a few. Here are several areas where this technology is making an impact:

Security and law enforcement

Face analysis has become a common way to quickly identify individuals in crowded places or surveillance footage, aiding criminal investigations and enhancing public safety. Law enforcement agencies use it to spot persons of interest in real-time — much more accurately than the human eye could — and compare them with those in facial recognition databases.


Hospitals and clinics are adopting facial recognition for patient management. These systems ensure accurate patient identification, reducing errors in medical record handling. This technology is beneficial when patients can’t communicate their identity and need to receive the correct treatment.


Retailers use face recognition to offer personalized experiences to customers, identifying people who come in often and tailoring services to their preferences. On the other hand, it's a helpful tool for spotting people who’ve shoplifted in the past and preventing them from doing it again. 

Banking and finance

The banking sector employs facial recognition to enhance customer security in transactions and services. It's most common in mobile banking apps and at ATMs for verifying your identity, making sure the person accessing the account is authorized.

Travel and hospitality

Airports and hotels are incorporating facial recognition for faster check-in and customs processes. It simplifies identity verification, reducing wait times and improving overall customer experience.


Educational institutions use facial recognition for various purposes, including monitoring attendance and enhancing campus security. This technology helps maintain a safe environment for students and staff alike by identifying unauthorized individuals on school premises.

5 benefits of facial recognition technology

Facial recognition technology offers a wide range of advantages, no matter where you’re using it:

  1. Enhanced security: One of the primary benefits of facial recognition is its ability to boost security significantly. Using unique facial features for identification minimizes the risk of unauthorized access, whether to a government building or your cell phone.

  2. Speed and convenience: Facial recognition technology streamlines identity verification processes. It’s easy to lose or compromise traditional methods like passwords or PINs, but a person’s face is a more reliable — and fast — identifier.

  3. High accuracy levels: Advancements in AI and machine learning have significantly improved the accuracy of facial recognition systems. While they aren’t perfect, they can sometimes even distinguish between identical twins. Some can also adapt to changes in appearance and accurately identify people in diverse lighting and angles.

  4. Fraud prevention: In the banking and finance sector, facial recognition authenticates transactions and verifies user identity, reducing the chances of financial fraud. It also helps monitor and prevent unauthorized access within banks and other institutions.

  5. Non-intrusive security: The contactless nature of facial recognition allows for identity verification without physical contact. It’s hygienic and more comfortable for people who don’t want to scan their fingerprints on a pad other people constantly touch.

Is facial recognition safe?

Facial recognition is safe, but it does have its criticisms. Some people aren’t comfortable with facial sensors, and less-developed systems have a history of misidentifying people. 

Here are some key topics in the face recognition conversation:

  • Privacy policies and consent: In some public places, you might not know if there’s a system reading your face — or where that data is going. All facial recognition systems should provide clear information on privacy policies and ask you to give informed consent before capturing and using your facial data.

  • Accuracy and misidentification: The technology's improving accuracy still has limitations. There’s a risk of misidentification, especially among certain demographic groups, raising concerns about fairness and discrimination.

  • Regulation and oversight: Facial recognition is relatively new, which means lawmakers are still developing regulatory frameworks. This includes laws and guidelines to govern how to use facial recognition technology in a way that respects privacy and human rights.
