Facial recognition technology (FRT) has been around for years now. However, with the technology rapidly evolving, including AI-based solutions, FRT is becoming even faster and better at analysing unique facial features. So, in this article, we’ll look into how this technology actually works, where it can (and is) used, as well as who are currently the key players in the industry.
How does facial recognition work?
At its core, facial recognition technology uses sophisticated AI, particularly machine learning (ML) and deep learning algorithms. The process begins with detection, where the system identifies and isolates a human face within an image or video. Next is analysis, also known as feature extraction, which involves mapping out the unique facial landmarks of your face.
For example, things like the distance between your eyes, the shape of your nose, the contour of your jawline, or the subtle differences in your eyebrows all make up who you are. This is also referred to as a “faceprint” or the biometric template of your face. Once this information is processed, it’s usually converted into a numerical code, which is matched with the one associated with you. The accuracy and reliability of facial recognition heavily depend on the quality of the database and the sophistication of the algorithms.
Diverse applications of FRT
Facial recognition’s applications are already extensive and growing daily. For instance, it’s already a critical tool in security and law enforcement. Agencies can use it to identify suspects from a vast database of CCTV footage, scan large crowds for a person of interest, secure access to sensitive facilities, and so on. You’ve also most likely run into it at the airport passport check, where the machine verifies your identity against your passport. In fact, many people believe your face will become your boarding pass at the airport in the future.
In commercial and consumer applications, FRT brings a lot of convenience. One of the most familiar uses is to unlock our smartphones and laptops just with a glance. Online retail shops are also increasingly offering personalised experiences to customers, using the same technology. Contactless payments can also now be authorised using facial verification instead of passwords. On social media, photo tags are automatically recommended, as platforms can recognise the people associated with you, based on the names you’ve provided.
Moreover, the healthcare sector is where we see a lot of important applications. Facial recognition technology can help prevent various medical errors by accurately identifying patients as well as streamlining hospital check-ins. Experimental systems are even aiming to monitor patient conditions, like diagnosing rare diseases or assessing their pain level, all by analysing their facial dysmorphology.
The benefits of facial recognition implementation
The implementation of facial recognition technology offers numerous incredible benefits across various different industries. Foremost is enhanced security – FRT enables proactive threat detection and more effective crime prevention, improving both public and private safety. Beyond security, it drives improved efficiency and automation. Processes like identity verification, employee check-ins or physical access control are streamlined, reducing the need for manual monitoring.
Of course, FRT brings many benefits to our day-to-day lives too, by making different tasks more seamless. We have quick, contactless, intuitive interactions with our technology, from unlocking a phone to entering a building. Modern systems boast impressive accuracy and speed, quickly becoming the new normal in our homes and workplaces.
Key players in the FRT services
If you are looking to implement facial recognition in your organisation, partnering up with a reliable company will be here. Here are some of the best service providers in the industry today:
Digital Sense
Using the DSBio Face Recognition System (FRS), Digital Sense aims to turn complex projects into simple solutions. Their technology boasts 99.76% accuracy, allowing for reliable identification and verification of faces in real-time.
NEC Corporation
Based in Japan, NEC Corporation is a global biometrics leader, offering high-accuracy facial recognition technology NeoFace. These are widely adopted by law enforcement, border control, and enterprises for robust identity verification and enhanced security.
Clearview AI
Clearview AI primarily serves law enforcement with a controversial, vast database from public internet sources. Its powerful search is a game-changer in police investigations, with 99%+ accuracy, although it has sparked some debates over data collection and privacy practices.
Thales
Thales excels in digital identity and security. They offer biometrics for government programs, enterprise access, secure IDs, aerospace, and advanced border management systems incorporating facial recognition.
The future of face recognition
Facial recognition technology can be absolutely transformative across many sectors, particularly as it keeps getting even faster, more precise, reliable, and powerful. However, despite all of its advantages, the technology is increasingly challenged with privacy concerns, as vast amounts of public data are collected to train it for security purposes. There are also rising worries regarding potential identity theft crimes, as AI face recognition is fast becoming widely accessible to everyone. Ultimately, the positives outweigh the negatives, and with enough transparency and accountability, it can continue to serve individuals and the public safely.
