Identity Verification with Amazon Rekognition

This sample, built using AWS Amplify, is meant to showcase recommended flows when using Amazon Rekognition for Identity Verification. There are two key components in this sample:

  • Frontend: A React/NextJS web application for exercising the key flows
  • Backend: An GraphQL based backend built using AWS AppSync

Flows

Users interested in implemented Identity Verification with Amazon Rekognition should consider the following flows.

New user registration

  1. Check face image quality via the DetectFaces API.
  2. Use SearchFacesByImage API against the collection(s) to check for any duplicate registration.
  3. Index the face image using IndexFaces API and use the ExternalImageID (Social Security number or a similar unique ID) parameter to associate the face embeddings with the ExternalImageID.
  4. Store the face image in the S3 bucket along with the user metadata (face-id returned from the IndexFaces API, SSN and S3 URL) in DynamoDB. The SSN or a unique person identifier can be used as a key to lookup S3 URL and the face-id.

New user registration w/ Id card

  1. Check face image quality via the DetectFaces API.
  2. Check face image quality of face on Id card via the DetectFaces API.
  3. Use CompareFaces API to ensure that the face on the supplied Id card and the face on the selfie match.
  4. Use SearchFacesByImage API against the collection(s) to check for any duplicate registration.
  5. Index the face image using IndexFaces API and use the ExternalImageID (Social Security number or a similar unique ID) parameter to associate the face embeddings with the ExternalImageID.
  6. Store the face image in the S3 bucket along with the user metadata (face-id returned from the IndexFaces API, SSN and S3 URL) in DynamoDB. The SSN or a unique person identifier can be used as a key to lookup S3 URL and the face-id.

Existing user login

  1. Check face image quality via the DetectFaces API.
  2. Search against the collection with SearchFacesbyImage API. If there is a face match, then return the use the faceId to return additional data about the user by cross-referencing against profile data in DynamoDB.
