Topic	Sub-topic
Principios básicos de las técnicas biométricas, características de los datos biométricos y tecnologías biométricas actuales.	Identity versus biometric traits. Types of biometric traits. Within and between variance of biometric signatures. Sensors dependency of biometric signatures. The seven pillars of biometrics. Feature extraction. Compression. Representation versus discrimination Differences among recognition, identification, verification and authentication. Types of errors: TER, ERR, FAR, FRR. Physiologic features: fingerprints, iris, face, palm, speech. Behavioral features: signature (static and dynamic), speech, expression, typing rate. Specificities, pros and cons when using every biometric trait.
Face recognition	The problem of face detection and normalization. Holistic techniques (eigenfaces, fisherfaces) versus local techniques (template matching, NCC, Elastic Bunch Graph Matching). The problem of variation in face pose and illumination. Shape and Appearance Models.
Iris recognition	Iris representation. Daugman algorithm. Wildes algorithm. IrisCode. Pros and cons of iris recognition.
Fingerprint recognition	Types of sensors. Minutiae representation and local texture representation. Hausdorff distance. Gabor filtering. Deformation tolerance.
Speaker recognition	Gaussian Mixture Models. Universal Model of Speakers. Cohorts. Text dependent or independent speaker recognition. HMM. Intra-modal fusion. State of the art systems.
handwritten signature recognition	Types of sensors. Feature extraction of static signatures: image statistics. Feature extraction of dynamic signatures: temporal parameters. DTW modeling, HMM modeling, Edit distance between chains. The problem of skilled forgeries.
Combination of classifiers	Combination of classifiers. Independent or uncorrelated sources. Classifiers fusion: intra-modal, extra-modal, algorithmic or scores fusion. State of the art systems for multimodal recognition.
Seguridade e privacidade das mostras biométricas	Técnicas de transformación do espazo de características ("salting", "hashing"). Sistemas criptobiométricos (métodos "key-binding" e "key-generation"). Ocultadción de datos en biometría.
