How Does Facial Recognition For Door Lock Access Work?

    Keyless digital locks have been on the market for some time, with some of the most common access modes available being fingerprint recognition, PIN code, and RFID cards. One door access mode that is gaining popularity with homeowners but is still somewhat rare in Singapore is facial recognition technology.

    While we are familiar with facial recognition being used to unlock our smartphones or digital gadgets, installing the technology into our everyday door locks is still a little ways off from being commonplace. As this technology becomes more affordable and accessible, there is a chance that you could one day unlock your HDB door or gate just by scanning your face.

    How facial recognition technology works

    Facial recognition technology is based on decades of machine learning and AI research. When a face is being programmed to be recognised by the lock, the computer takes a highly accurate photo of the person using the RGB colour spectrum. This photo is then processed by AI, which makes millions of floating point computations across the face to create a unique facial signature.

    Each time the user activates the door access protocol, the photo taken of their face by the built-in camera will be compared against this unique signature. The floating point computations are what enable the same user to activate the lock even if they are making a different expression. Computers that have been trained through machine learning (AI) will be able to sense and verify the unique identity of the user.

    Pros of facial recognition technology

    Facial recognition door access stands to have several key benefits for homeowners in Singapore:

    • Security: As a unique facial signature is required, this ensures greater security for your home and household. Good facial recognition technology also includes anti-spoofing measures to prevent false verification.
    • Hygiene: Imagine shifting from keyless locks to contactless locks! The COVID-19 pandemic has brought up concerns over physical contact or shared surfaces to the forefront, and being able to unlock our HDB door or gate without touching it would definitely help ease our worries.
    • Convenience and accessibility: The next time you come home with your hands full of groceries you won’t have to put your bags down just to unlock your door. Contactless digital locks will make daily life so much easier for everyone – from busy parents with their arms full of kids’ toys or diaper bags; to disabled users who can unlock their front door without lifting a finger.

    That being said, there are still some lingering concerns about facial recognition technology including:

    • Errors in recognition
    • Concerns over accuracy when users are wearing face masks or other items that may obscure the face
