ID Verification System

Bank-grade identity verification system built on AWS with real-time auto-decision and human review fallback.

Architecture

• Frontend: React + TypeScript (deployed to CloudFront)
• Backend: AWS Lambda + API Gateway (serverless)
• Region: ca-central-1 (Canada Central)

Core AWS Services

• Amazon Textract (ID OCR)
• AWS Rekognition Face Liveness
• AWS Rekognition CompareFaces
• AWS Step Functions (workflow orchestration)
• Amazon DynamoDB (data storage)
• Amazon S3 (encrypted document storage)
• Amazon Cognito (reviewer authentication)
• Amazon SQS (review queue)

Decision Logic

Check	PASS	REVIEW	FAIL
Face Similarity	>= 90%	70-89%	< 70%
OCR Confidence	>= 85%	70-84%	< 70%
Liveness	Pass	-	Fail
Document Expiry	Valid	-	Expired
