The Biometric Face Match and Liveness checks determine that the person undergoing the identification process is the legitimate holder of the provided identity document and is physically present during the verification.
Biometric Face Match
The portrait photo is extracted from the uploaded identity document, and then using advanced facial recognition algorithms, it analyses and compares the facial features in the ‘selfie’ with those in the document photo. The system calculates a score based on the confidence of the match. If the score passes the required threshold, the check will pass.
Active Liveness Detection
This is achieved through a series of real-time challenges that require physical interaction. For example, the system may ask the user to smile or move their head in a certain direction. The system then analyses the user's responses to these prompts to check for natural movement and variation, which would be indicative of a live human being. By including these tests, liveness detection adds an extra layer of security by preventing spoofing attacks, such as using a photograph or a video in place of a live face.
These tests are designed to ensure that the biometric data being provided during an identity verification process is from a real, live personand not a static image.
Physical Tamper Checks
This uses matching and pattern discrimination techniques, based on machine learning algorithms, to identify signs of the ID document having been tampered with.
It identifies feature and noise levels in regions corresponding to printed characters and attempts to detect whether the image is an authentic physical ID document or a recapture on paper or a screen. When detecting portrait photo substitution, some fraudsters will physically replace the photograph on a genuine identity document with another to masquerade as the bona fide holder of the document. Portrait photo tamper checks need to account for large intra-class diversity (background, watermark, ethnicities, etc.), varying lighting conditions (day, night, exterior, interior, etc.) and image quality(camera, compression, blur, etc.).
NFC Chip Reader
This technology provides the highest possible standard for ID verification. When available, the NFC chip is scanned by holding the Passport next to the smart phone and the data held is electronically transferred, including the original encrypted digital image of the portrait photo.
