On-chain/decentralized identity primitives and IoT/M2M verification using TinyML. LLM-based continuous compliance automation. Recent restructuring indicates pivot toward leaner enterprise sales. Payments integration planned.
<p>AI-powered document forgery detection that analyzes 14,000+ global ID types in real-time to catch tampered, synthetic, or fraudulent documents before onboarding completes.</p>
It's like having a forensic detective instantly inspect every ID handed to your bouncer, catching even the best fake IDs before anyone gets through the door.
Didit's document verification engine uses proprietary deep learning models trained on 14,000+ document types across 220+ countries to perform real-time forgery detection during customer onboarding. The system combines OCR, MRZ validation, barcode parsing, and NFC chip reading with convolutional neural networks that analyze micro-visual patterns—font consistency, hologram placement, pixel-level tampering artifacts, and printing technique signatures—to distinguish genuine documents from sophisticated forgeries, including AI-generated synthetic IDs. The models are continuously retrained on emerging fraud vectors, enabling the platform to adapt to new forgery techniques within days rather than months. This multi-layered approach catches document fraud that traditional rule-based systems miss, while maintaining sub-3-second verification times even in low-connectivity environments, directly reducing financial losses from fraudulent account creation and ensuring regulatory compliance across jurisdictions.
It's like Shazam for fake IDs—except instead of recognizing songs, it recognizes the subtle "off-key notes" in a forged passport that no human eye would catch.
<p>ISO 30107-3 certified biometric liveness detection that uses passive and active AI challenges to defeat deepfakes, face swaps, and presentation attacks during identity verification.</p>
It's like a digital lie detector for your face that can tell if you're a real person or a deepfake video trying to sneak past security.
Didit's biometric liveness engine combines passive and active challenge-response mechanisms powered by deep neural networks to verify that a real, live human is present during identity verification—not a photo, video replay, 3D mask, or AI-generated deepfake. The system performs face-to-document matching using embedding-based similarity models while simultaneously running anti-spoofing classifiers trained on adversarial datasets that include the latest deepfake generation techniques (GANs, diffusion models, face-swap tools). Passive liveness analyzes involuntary micro-movements, skin texture, light reflection patterns, and depth cues from standard smartphone cameras without requiring user interaction, while active liveness prompts specific gestures or expressions when risk scores are elevated. The pipeline is ISO 30107-3 certified at 99.9% accuracy and is designed to run efficiently on-device or server-side, adapting to device capabilities and network conditions. Continuous retraining against newly discovered attack vectors ensures the system stays ahead of the rapidly evolving deepfake landscape.
It's like a nightclub bouncer who doesn't just check your ID photo—they make you blink, smile, and turn your head to prove you're not a cardboard cutout of someone else.
<p>AI-driven adaptive verification orchestration that dynamically adjusts identity check sequences and risk thresholds in real-time based on behavioral signals, device intelligence, and fraud patterns.</p>
It's like a smart airport security line that automatically sends low-risk travelers through the fast lane and flags suspicious ones for extra screening—all without a human deciding who goes where.
Didit's adaptive workflow orchestration engine uses machine learning to dynamically compose and sequence identity verification steps in real-time based on a continuously updated risk profile for each user session. Rather than applying a static, one-size-fits-all verification flow, the system ingests signals from device fingerprinting, IP geolocation, behavioral biometrics (typing cadence, swipe patterns, session timing), document quality scores, and historical fraud patterns to calculate a dynamic risk score that determines which checks are applied and in what order. Low-risk users experience a frictionless, minimal-step flow (e.g., document scan + passive liveness), while high-risk sessions are automatically escalated to additional checks (active liveness, NFC chip reading, manual review queue, enhanced AML screening). The orchestration layer learns from verification outcomes—approvals, rejections, false positives, fraud confirmations—to continuously refine its routing logic and risk thresholds per geography, industry vertical, and fraud typology. This reduces unnecessary friction for legitimate users (improving conversion), concentrates expensive verification resources on genuinely suspicious cases (reducing cost), and adapts to emerging fraud campaigns faster than manually tuned rule systems.
It's like a GPS that reroutes your identity check in real-time—if the road looks clear you cruise through, but if it detects trouble ahead, it automatically adds extra security checkpoints before you reach your destination.
