The Digital Onboarding Toolkit provides results to evaluate trust that can be given to a person verifying his/her identity remotely.
When the Digital Identity Service has both ID document photo and selfie photo, it can perform the inspect functions. These return various values that can be used as Trust factors.
Based on these, the solution using the DOT can automatically decide if the person’s identity can be trusted or not, or if there is a human inspection and decision needed. Ideally, all decisions should be automatic. However, at the beginning of a project it is better to analyze more edge cases manually to narrow down thresholds and then reduce needed manual input.
