The Online Signature Authentication Tool is a Biometrics project that combines Retraining loop and Behavior model, built with Streamlit UI. The project follows a clean, modular pipeline where trait capture, processing, and presentation stay separated, making it easy to test, extend, and present. It showcases practical biometric techniques while producing a working, demo-ready application.
Passwords and cards can be stolen, shared, or forgotten, making traditional authentication insecure and inconvenient. Without a biometric approach built on Behavior model and Streamlit UI, users cannot verify identity reliably using physical traits, and there is no secure, convenient way to control access.
This project applies biometric recognition through Retraining loop, orchestrated with Streamlit UI and Behavior model. The pipeline is designed for accuracy and security, with enrollment, matching, and clear evaluation. It produces consistent, reusable results and can be adapted to related identity tasks with minimal changes.

Modular biometric pipeline around Retraining loop and Behavior model
Enrollment and verification workflows
Secure template storage
Clear logging, metrics, and error handling
Clean interface for viewing results
Evaluation of matching accuracy
The project is layered: the capture layer acquires and preprocesses the trait through Retraining loop; the recognition layer extracts and matches features with Streamlit UI and Behavior model; and the output layer formats and presents results via Template storage. Shared configuration, logging, and evaluation modules support all layers, keeping the system secure and easy to extend.
