Introduction

vali-Das is a software as a service (SaaS) provided by Veridas, which performs onboarding processes based on ID document validation and face biometry.

This service exposes a REST API that can be used to call all of its functions. This API allows to read the text fields printed on the ID documents (OCR) and verify security measures by using multiple techniques. It also allows biometric comparison between the photo printed on the ID document and a selfie photo. Finally, vali-Das allows to verify that the user carrying out the process shows evidence of being alive.

From an architecture point of view, vali-Das is an orchestration like service which manages the calls to the ID document analysis service called IDentidas, the face biometry service called das-Face and a proof of life service. vali-Das also is in charge of retrieving all the results and data which these microservices generate and make them available through its API, easing the process for doing an on-boarding.
