Changelog

v1.1.0 — February 2025

Image persistence: Verification images (document front, document back, selfie, liveness frames) are now automatically persisted to Google Cloud Storage for compliance and audit purposes
Image retrieval API: New endpoints to list and retrieve verification images with signed URLs
- GET /verifications/{id}/images — list available images
- GET /verifications/{id}/images/{imageType} — get a 15-minute signed URL
SDK updates: Both iOS (v1.1.0) and Android (v1.1.0) SDKs now report imagePersisted status in verification results
Async processing: Image uploads are processed asynchronously — the imagePersisted field on the verification object confirms when persistence is complete

Android SDK v1.1.0: Added imagePersisted field to VerificationResult, automatic image persistence support
iOS SDK v1.1.0: Added imagePersisted property to KoraVerificationResult, automatic image persistence support

Face matching: FaceNet 512-dimensional embedding comparison with >99% accuracy
Liveness detection: Active liveness with 6 challenge types (blink, smile, turn left/right, nod up/down)
Anti-spoofing: 5-layer analysis (texture, frequency, challenge, temporal, quality)
Compliance screening: CEngine integration for sanctions, PEP, and adverse media screening
Scoring engine: Composite scoring with configurable thresholds for auto-approve, manual review, and auto-reject
Webhooks: 9 event types with HMAC-SHA256 signature verification and exponential backoff retry
