Description
This course contains the use of artificial intelligence. Some of the videos in this course were created using AI-assisted tools. These tools were used to professionally produce high-quality visuals and narration in order to make the learning process clearer, more engaging, and more efficient. All learning materials were carefully selected, organized, and updated by the instructor to reflect current knowledge and best practices. AI was used as a supportive technology, not as a substitute for subject-matter expertise, instructional design, or academic responsibility.

Biometric technologies have become central to modern identity systems, powering authentication in smartphones, border control, law enforcement, healthcare, and digital security. Yet many courses only scratch the surface, focusing on applications without explaining how biometric systems actually work.

This course provides a comprehensive and technically grounded introduction to biometric systems. You will learn the fundamental principles behind biometrics, explore major biometric modalities, understand how system performance is evaluated, and study security threats and countermeasures.

The course begins with core concepts, including biometric system architecture, enrollment, database design, performance metrics, and error analysis. You will then explore key biometric modalities such as signature, face, iris, fingerprint, and hand-based biometrics, with clear explanations of their underlying techniques and challenges.

A dedicated section focuses on biometric security, covering attack models, presentation attacks, spoofing, and liveness detection. Ethical concerns, misuse, and future trends in biometric identity systems are also discussed, providing a balanced technical and societal perspective.

This course is designed for learners who want more than high-level descriptions—it emphasizes clarity, rigor, and practical understanding, making it suitable for academic study, research preparation, and professional development.
