This is an on-device face recognition SDK for Android that performs face detection, liveness detection (anti-spoofing via color flash, actions like blinking/smiling), and 1:N/M:N face search entirely offline without network connectivity. It uses local ML inference to process face biometrics on the device, ensuring data privacy by not uploading face data. The SDK supports Android 5-16 and UVC USB cameras, running all ML models locally for efficient integration into applications requiring biometric verification.
