Platform Features
Hybrid Signature Verification
Dual-engine verification combining AI Vision analysis (60%) with ONNX Siamese CNN machine learning (40%) for maximum accuracy.
- AI Vision providers: OpenAI GPT-4o, Anthropic Claude, Google Gemini, xAI Grok
- ONNX Siamese CNN for ML-based similarity scoring
- Weighted hybrid scoring (60% AI + 40% ML)
- Stroke dynamics capture (pressure, speed, angle)
- Reference signature management and comparison
- Batch signature processing
14-Point ID Fraud Detection
Comprehensive identity document verification with barcode scanning, hologram detection, and multi-provider analysis.
- 14-point fraud check pipeline
- Barcode scanning: PDF417, QR, DataMatrix
- 3 ID verification providers: AI Vision, Persona, ID Analyzer
- Document type detection (passport, license, ID card)
- MRZ (Machine Readable Zone) parsing
- Hologram and tamper detection
NFC Passport Chip Reading
Read and validate NFC passport chips via desktop USB readers and native mobile NFC for cryptographic identity verification.
- Desktop USB NFC reader support
- Mobile native NFC (iOS + Android)
- BAC (Basic Access Control) authentication
- PACE protocol support
- Chip data extraction and validation
- Digital signature verification
Liveness Detection
Real-time camera-based liveness detection comparing a live photo to the document photo to prevent spoofing.
- Live photo capture via webcam/camera
- Face comparison against document photo
- Anti-spoofing measures (screen detection)
- Depth and texture analysis
- Real-time feedback and scoring
- Configurable confidence thresholds
AI Brain with 12 Providers
Centralized AI orchestration with 12 configurable providers, editable prompts, and a RAG knowledge base for intelligent document analysis.
- 12 providers: OpenAI, Gemini, Claude, Grok, Mistral, Groq, DeepSeek, Perplexity, Cohere, Together AI, HuggingFace, Ollama
- Editable system prompts per verification type
- RAG knowledge base with 8 retrieval strategies and vector search
- Provider fallback chain for reliability
- Token usage, cost, and latency tracking per provider/feature
- AI activity logging and audit trail
Signature Profile Learning
Per-signer profiles that adapt to each signer's natural variation. Verified signatures become training samples; thresholds adjust automatically.
- Profiles built from multiple verified samples per signer
- ML compares against ALL profile samples — picks best match
- Adaptive thresholds based on each signer's variation range
- Variation metrics: consistency score, stroke pressure, angle range
- Profiles surface in the verification UI as 'learned' badges
- Multi-sample hybrid scoring resists single-sample drift
E-Verify (Form I-9 Federal)
Built-in DHS E-Verify case management for U.S. employment eligibility verification — submit, check, and close cases via the official federal API.
- Real DHS E-Verify API integration (initial / check / close)
- Form I-9 workflow with status tracking
- Case management UI with submission history
- Requires DHS MOU credentials to activate against live API
- Audit trail of every case action with timestamps
- Designed for state, federal, and large-employer compliance
2-Party Document Signing
Send a document for counterparty signature via a public signing link — captures stroke dynamics, IP, and timestamp on submission.
- Public signing pages — no account required for the counterparty
- Stroke-dynamics capture (pressure, speed, angle, pauses)
- Tamper-evident audit log with IP, user-agent, timestamp
- Signed document delivered back to the originator
- Works on web and mobile — touchscreen and stylus supported
- Pairs with the verification engine for downstream comparison
Logic Rules & Webhooks
Automation engine with configurable logic rules and HMAC-SHA256 signed webhooks for integration with external systems.
- Visual logic rule builder
- HMAC-SHA256 signed webhook payloads
- Event-driven triggers (verification.completed, fraud.detected, id.verified, id.rejected)
- Custom action chains
- BullMQ retry with exponential backoff (5 retries)
- Webhook delivery logs and debugging
Developer API (API-as-a-Service)
REST API for external developers with X-API-Key authentication. Three tiered plans with rate limits, monthly quotas, and Stripe-managed billing.
- X-API-Key header auth, ggv_-prefixed keys, SHA-256 hashed in DB
- Basic ($99/mo, 500 calls, 20 rpm)
- Pro ($299/mo, 2,000 calls, 60 rpm)
- Enterprise ($899/mo, 10,000 calls, 200 rpm)
- Endpoints: /v1/verify/signature, /v1/verify/id, /v1/usage, /v1/plans
- Redis sliding-window rate limiting with DB fallback
