The Technical Backbone: A Deep Dive

1. Facial Mapping:

Face Mapping

Onfido’s facial recognition journey begins with meticulous facial mapping. Let’s assume a cartographer meticulously charting the contours of a new land. Similarly, Onfido’s algorithms analyze your face, pinpointing key landmarks like the distance between your eyes, the shape of your nose, and the curve of your jawline. These landmarks act as anchors, allowing the technology to extract unique features like wrinkles, freckles, and even subtle asymmetries.

But the map isn’t just flat. Onfido adds another layer of precision by utilizing 3D depth maps. Just like a topographical map, revealing the subtle bumps and valleys of your facial terrain. This 3D understanding allows Onfido to differentiate between a real face and a flat image, even when lighting conditions or expressions change.


However, the world of facial mapping isn’t without its challenges. Lighting variations can cast shadows and distort features, while facial expressions can temporarily alter the landscape. Onfido’s algorithms, however, are trained on a vast library of diverse faces under various conditions, allowing them to account for these nuances and create a robust, individualized map of your unique facial fingerprint.

2. Spoof Detection Algorithms

Spoof Detection

Once the map is created, it’s time to stand guard against imposters. Onfido employs a sophisticated arsenal of spoof detection algorithms to distinguish between a real face and a fake one. These algorithms tackle various types of spoofing attempts:

  • Photos and videos: Onfido analyzes subtle inconsistencies in lighting, reflections, and motion patterns to expose these static or pre-recorded attempts.
  • Masks: 3D depth maps and advanced texture analysis can reveal the unnatural smoothness or inconsistencies in depth present in masks, even the most sophisticated ones.
  • Deep Fakes: Onfido’s algorithms go beyond the surface, analyzing micro-movements and inconsistencies in facial expressions to differentiate between real and synthetic faces.

But Onfido doesn’t just rely on reactive measures. It also employs liveness challenges, prompting you to blink, turn your head, or smile. These simple actions, impossible for a static image or video, confirm the presence of a live person behind the face.

Beyond challenges, Onfido utilizes passive liveness detection, analyzing subtle involuntary movements like micro-expressions and blood flow patterns. These subtle bio-signals, undetectable by even the most skilled impersonator, provide an irrefutable layer of liveness verification.

3. AI Training Processes

AI Training

The heart of Onfido’s technology lies in its AI training processes. Just like a child learns by seeing and interacting with the world, Onfido’s algorithms are trained on a massive and diverse dataset of real faces and spoofing attempts. This constant learning ensures that the algorithms stay ahead of the curve, adapting to new spoofing techniques and evolving threats.

The importance of large and diverse datasets cannot be overstated. Just as a child exposed to a variety of people and experiences develops a well-rounded understanding of the world, Onfido’s algorithms trained on a global spectrum of faces learn to recognize the nuances of human individuality, regardless of ethnicity, age, or gender.

But the journey doesn’t stop there. Onfido is at the forefront of research and development in AI for identity verification. They are constantly pushing the boundaries, exploring new techniques like explainable AI and federated learning to further enhance the security and accuracy of their technology.

This ongoing dedication to innovation ensures that Onfido remains a trusted guardian in the ever-evolving landscape of digital identity verification.

Onfido Securing Identities Across Industries

Onfido’s facial recognition and liveness detection technology isn’t confined to a lab; it’s actively safeguarding identities across diverse industries. Here are some real-world examples:

1. Finance

Streamlined KYC and onboarding

Suppose you are applying for a loan online and verifying your identity in minutes with a selfie. Onfido empowers financial institutions to offer secure and convenient onboarding, reducing paperwork and fraud risks. 

For example, 

N26, a leading mobile bank, leverages Onfido to verify customer identities during account opening, leading to a 70% reduction in onboarding times.

2. Healthcare:

Combating prescription fraud

Pharmacies using Onfido to verify patients’ identities before dispensing controlled substances, preventing unauthorized access and prescription fraud. This helps protect both patients and healthcare providers.

For example, 

Babylon Health, a digital healthcare provider, which saw a 99% reduction in fraudulent prescription attempts with Onfido.

3. E-commerce:

Boosting account security and preventing fraud

Online marketplaces integrate Onfido during account creation to verify user identities and prevent fraudulent activity. This fosters a secure and trusted environment for both buyers and sellers. 

For example,
