Identity verification APIs handle highly sensitive personal and biometric data, making robust security essential to prevent breaches, fraud, regulatory penalties, and reputational harm. Recommended practices include strong authentication and authorization through granular API keys, OAuth 2.0, OpenID Connect, and mutual TLS; TLS 1.2 or higher for data in transit; encryption such as AES-256 and secure key management for stored data; strict input validation, output encoding, and nonrevealing error handling to reduce injection and scripting risks; and rate limiting and throttling to deter denial-of-service attacks, brute-force attempts, and scraping. Ongoing protection also requires API logging, SIEM integration, security audits, penetration testing, and a defined incident-response plan. Didit presents its AI-native identity-verification platform as incorporating these measures, citing ISO 27001 certification, GDPR compliance, end-to-end encryption, NFC-based document verification, liveness detection, modular APIs, and configurable workflows for services including ID, facial, address, and AML verification.
