Module Overview • Module Aims • To cover all modern approaches to biometrics, in the context of automatic computerised methods of identifying an individual based on who they really are - using a variety of attributes such as finger-prints, iris scans etc.
Indicative Syllabus I • Generic mathematical techniques for pattern recognition and digital filtering. • Frequency domain analysis - Fourier and other transforms. • Digital signal processing algorithms. • Benefits of biometrics to identification systems. • Enrolment and template creation. • Accuracy in Biometric systems. False match rates and false non-match rates. • Derived metrics
Indicative Syllabus II • Fingerprint scan. Image acquisition and processing. Competing technologies. Finger scan problems. • Facial scan. Image acquisition and processing. • Iris scan. Image acquisition and processing. • Voice Scan. Speech processing. Implementation of speech processing algorithms. • Other physiological biometrics - signature and key-stroke scanning. • Multifactor identification. • Privacy risks of biometrics.
Learning Outcomes • Awareness of the practicability and applicability of modern method of biometrics. • That an individual's identity can be ascertained to a very high degree of confidence using appropriate sensors and systems. • The common mathematics of pattern recognitionthat underpins this technology. • An understanding of signals: waveforms & spectra • Competence at implementing verification algorithms • Ability to program MATLAB scripts • Ability to use HTK (Hidden Markov Model Toolkit) for verification design
Module Overview • Achieving the aims of the modulewill involve the following: • Communication skills • Group Work skills • Organisational skills • Personal skills • Problem solving skills • Programming skills • Information Technology skills • Cross-disciplinary partnerships • Skills transfer • Module mailing list • Discussion forum; No code!!!
