Notary: Biometric ID Selections procedure

There are various options to select ID Verification with Biometric Matching without creating that ID verification process as your default. As seen below you can change from the default KBA & ID Verification to just ID Verification – Credential Analysis simply by checking that box!

Biometric ID selection procedure for id verification

Another point at which you can elect Biometric is at the individual signer step. In this way one signer could be KBA/ID, one signer Personally known and the other Biometric (ID Verification-Credential Analysis) only.

There is also a third spot where the ID verification method can be changed per/signer and that is at the final step where you send out the session email invite.

Once the signer who’s identity was verified via forensic examination of the submitted ID and a Liveness/Biometric test is performed. The resulting data and pictures are available for display to the notary in session as seen below. Where the front and back of the verified ID are displayed, a larger image of the picture side of the ID and a copy of the face selfie taken after the liveness test. To the right is a live display of the signer wherein you could ask them to hold up the ID that was verified.

Secured Signing Inc, provides a Biometric document authentication process to determine authenticity, and to extract face image as well as demographic data such as name and address.  The face image extracted from the ID document is available post processing for biometric facial comparison to a live selfie provided at the same time the ID is presented for authentication.


Information About Face Match & Liveness Detection:


Face analysis uses a series of attributes such as:

·       the head pose – orientation in a 3D space

·       a guess at an age

·       what emotion is displayed

·       if there is facial hair or the person is wearing glasses

·       whether the face in the image has makeup applied

·       whether the person in the image is smiling

·       blur – how blurred the face is (which can be an indication of how likely the face is to  

        be the main focus of the image)

·       exposure – aspects such as underexposed or over exposed and applies to the face in

        the image and not the overall image exposure

·       noise – refers to visual noise in the image. If you have taken a photo with a high ISO

        setting for darker settings, you would notice this noise in the image. The image looks

        grainy or full of tiny dots that make the image less clear

·       occlusion – determines if there may be objects blocking the face in the image


While glasses, sunglasses, or reflections (obfuscating areas around the eyes) or light in glasses can negatively impact a match and best practice is to remove them for the selfie, it is not required.

The picture below provides an idea of what gets measured so you can see why masks or eyeglasses may, or may not, present problems to the score.  This is not a perfect example of all things considered in the algorithm.
