Technical Architecture: Core Components
To achieve deterministic verification outcomes at scale, the solution is built on a modular, service-oriented architecture with secure data flows, real-time decisioning, and auditable logs. Core components include:
- Identity Verification Engine: orchestrates KYC checks, document verification, and biometric risk scoring via Megapersonal and other providers. Supports fallback to multiple providers to maximize success rates.
- Phone Number Validation Layer: carrier checks, number normalization, MSISDN formatting, porting status verification, and spam risk scoring across major telecom operators.
- OTP and Verification Delivery: generation of time-bound one-time passwords (OTP), rate limiting, and intelligent retry strategies with delivery optimization for SMS, voice, or push channels.
- Policy and Decision Engine: risk scoring, policy rules, and dynamic thresholds that determine whether a user proceeds, requires additional verification, or is blocked.
- Data Security and Compliance Layer: encryption at rest and in transit, role-based access control, audit trails, and data residency controls aligned with UK GDPR and applicable Canadian laws.
- API Gateway and Orchestration: secure, scalable REST and SMPP interfaces, with webhooks and event streams to downstream systems such as CRM, risk dashboards, and SIEM tools.
Step-by-Step Verification Workflow: Detailed, Actionable Procedure
The following step-by-step solution is designed for deployment as a repeatable, auditable process. It ensures consistent account verification across use cases, from onboarding to ongoing risk management.
- Policy Definition and Onboarding Scope: Establish verification levels by customer segment (new sign-ups, high-value accounts, financial services clients) and define the data elements required for identity checks. Align with regional regulations and internal risk appetite.
- Data Capture and Normalization: Collect essential signals such as the user-provided identity data, phone number, IP address, device fingerprinting, email, and billing information. Normalize fields to canonical formats to enable cross-provider matching.
- Phone Number Validation and Carrier Insight: Validate the phone number format, detect country code, check number portability, and query carrier- or operator-level risk flags. This step reduces exposure to synthetic or stolen numbers and improves routing decisions for the final delivery.
- Identity Verification and KYC Validation: Invoke Megapersonal or alternative providers to verify identity documents, facial biometrics, and background risk signals. Apply a multi-factor risk score that combines document integrity, biometry consistency, and behavioral signals.
- Risk Scoring and Decision Rules: Aggregate identity, device, network, and number signals into a composite risk score. Apply business rules to decide: proceed with verification, require additional checks (e.g., video verification), or block the account.
- OTP Generation and Channel Selection: For verified users, generate OTPs with a strict TTL. Choose SMS, voice, or app-based verification channels based on risk profile, user region, and carrier reliability. Enforce per-second and per-minute rate limits to avoid abuse.
- Delivery Orchestration and Acknowledgement: Route messages through a carrier-grade SMS gateway, monitor MT delivery reports, MO replies, and network acknowledgments. Implement retry logic with exponential backoff and intelligent fallback to alternate routes (including kartina canada pathways for Canadian numbers).
- Webhook Callbacks and Event Streaming: Deliver real-time status updates to downstream systems via webhooks. Provide compile-time signature verification (HMAC-SHA256) to authenticate inbound events and protect against tampering.
- Audit Trails, Logging, and Compliance: Maintain immutable logs of all verification decisions, data processing steps, and user consent records. Ensure data retention policies and deletion workflows comply with UK GDPR and local Canadian requirements.
- Continuous Monitoring and Adaptive Governance: Continuously monitor fraud indicators, model drift, and spoofing attempts. Trigger periodic policy reevaluation to adapt to evolving threats and regulatory changes.
