BioSignature is a biometric identity verification system that combines facial recognition, liveness detection, and document analysis to perform secure Know Your Customer (KYC) checks. It creates a unique biometric signature from multiple data points to verify that a person is who they claim to be.
ArcFace is a deep learning model that maps a face into a high-dimensional embedding vector. When a user submits a selfie alongside an ID document photo, ArcFace generates embeddings for both images and computes a cosine similarity score. A score above the configured threshold confirms the faces belong to the same person, providing highly accurate one-to-one verification.
Liveness detection determines whether the biometric sample comes from a live person rather than a spoofing artifact such as a printed photo, screen replay, or 3D mask. BioKYC uses multi-frame analysis and challenge-response techniques to confirm genuine human presence before proceeding with identity verification.
BioKYC collects facial imagery from a live selfie capture and from the photo on the submitted identity document. These images are processed to extract facial embeddings (numerical vectors) used for comparison. No raw images are retained beyond the verification session unless explicitly configured by the integrating organization.
The anti-spoof module achieves high accuracy by analyzing texture, depth cues, and temporal signals across multiple frames. It reliably rejects common presentation attacks including printed photos, screen replays, and paper masks, while maintaining a low false-rejection rate for genuine users.
Yes. All biometric data is encrypted in transit and at rest. Facial embeddings are stored separately from personally identifiable information, and access is restricted through role-based controls. The system is designed to comply with data protection regulations and supports configurable data retention policies.
