Alibaba Cloud ID Verification is an AI-powered eKYC (Electronic Know Your Customer) solution designed to authenticate user identities in real time. It leverages OCR-based ID recognition, liveness detection, facial comparison, and identity validation to automate the identity verification process. The platform supports identity documents from over 100 countries and regions and is powered by the Qwen large language model (LLM) and Qwen-VL vision model, enabling high-accuracy recognition with as few as 10 sample documents. It achieves an attack interception rate exceeding 99%, defending against spoofing attacks involving masks, printouts, synthetic images, and document tampering. The service includes anti-injection mechanisms to detect device anomalies and prevent injection attacks. Models can be upgraded within hours to address emerging threats, with near-real-time supplementary model analysis and rule-based policy intervention. Integration is supported via SDKs, HTML5 apps, and APIs. Key modules include eKYC, Liveness Detection, ID Recognition, Non-Doc Verification (validating ID numbers, names, phone numbers, and bank account numbers against authoritative data sources), and Credential Detection for voucher and invoice verification. The solution targets industries such as financial services, live streaming, social media, and ride-hailing, supporting use cases including user registration, login, and sensitive transaction authentication.
