Fingerprint Recognition: Basics and Recent Advances
: This tutorial introduces fingerprint recognition in a top-down fashion.
Some general schemes are provided to explain the overall architecture of a fingerprint
recognition system. Then, the main components (acquisition device, feature extraction,
and matching) are discussed in detail. Different state-of-the-art approaches are
presented and compared, and the most critical difficulties in fingerprint recognition
are pointed out. The recently proposed Minutiae Cylinder Code (for fingerprint
representation and matching) will be discussed in detail. Hot topics like synthetic
generation, latent fingerprint enhancement and performance evaluation are also
discussed. Live examples and demos of several techniques are shown during the
lecture to better explain the main concepts.
List of Topics:
- Fingerprint Sensing
- Feature Extraction (orientation, frequency, singularities, minutiae)
- Matching (minutiae based, texture based)
- MCC (Minutiae Cylinder code)
- Synthetic generation
- Latent fingerprints enhancement
- Performance evaluation (FVC on-Going)

Electronics, Informatics and Systems - DEIS). He teaches "Computer Architectures" and "Pattern
Recognition" at Computer Science, University of Bologna, Cesena. Davide Maltoni's research
interests are in the area of Pattern Recognition and Computer Vision. In particular, he is
active in the field of Biometric Systems (fingerprint recognition, face recognition, hand
recognition, performance evaluation of biometric systems). Davide Maltoni is co-director of the
Biometric Systems Laboratory (BioLab), which is internationally known for its research and
publications in the field. Several original techniques have been proposed by BioLab team for
fingerprint feature extraction, matching and classification, for hand shape verification, for
face location and for performance evaluation of biometric systems. In particular, BioLab
developed and published the first algorithm able to meet the FBI error requirements for
automatic fingerprint classification and developed SFinGe, the first effective method for
generating realistic synthetic fingerprint databases. In cooperation with Prof. A.K. Jain from
Michigan State University and Prof. J. Wayman from San Josè University, BioLab organized the
First, Second, Third and Fourth International Competitions for Fingerprint Verification
Algorithms (FVC2000, FVC2002, FVC2004 and FVC2006). Davide Maltoni is co-author of the Handbook
of Fingerprint Recognition published by Springer, 2009, and co-editor of Biometric Systems -
Technology, Design and Performance Evaluation Springer, 2005. He holds three patents on
Fingerprint Recognition. Davide Maltoni served as associate editor of the international
journals: Pattern Recognition and IEEE Transaction on Information Forensic and Security. He has
been elected IAPR (International Association for Pattern Recognition) Fellow 2010.

: This tutorial will cover the scientific basis of iris recognition, the technical
approaches to iris image acquisition and recognition, as well as challenges, limitations,
and future research directions in iris recognition. List of topics:
- Scientific basis for iris recognition Epigenetic biometric features. Origins of
randomness and uniqueness in biological traits; anatomy, physiology, genetics, and development
of the iris. Metrics such as entropy and their relationship to biometric collision avoidance.
Phenotype and genotype. Challenges in acquiring iris images. Evidence for change, or stability
in iris patterns over time. "Iris diagnosis." Medical conditions that may affect the iris.
Foundations of statistical decision theory and pattern recognition.
- Technical approaches to iris image acquisition and recognition. Illumination of
the eye, optical resolution, capture volume, and bounds on motion and depth-of-field. Applicable
ISO/IEC Standards governing iris image properties, alternative image types, and quality metrics.
Predicting performance from quality metrics. Compressibility. Segmentation algorithms,
normalisation, occlusions and anomalies. Methods for extracting and encoding iris features, and
dissimilarity metrics. The mainstream Gabor wavelet phase and Hamming Distance algorithm, and
some alternative approaches. Speed and performance benchmarks. Major deployments around the
world, and their use cases.
- Challenges, limitations, unknown questions, and current research.
Expanding the envelope for iris acquisition: getting beyond the "in your face" iris camera and
the "stop and stare" user interface; achievements of "iris at a distance" and "iris on the
move." Doing all the image processing and encoding at the video frame-rate (30 Hz). Bit-parallel
match logic and parallelisability of database searches, with benchmark 1 million iris
comparisons per second per single-core CPU. Use of Codex and indexing methods ("Panopticon")
when even that is not fast enough. De-duplication of national-sized databases, and the India
Aadhaar / UIDAI. What can we say about the uniqueness and non-collision of iris patterns when
(so far) only 1.2 trillion iris pair comparisons have been performed. Anti-spoofing
countermeasures and the escalating anti-anti arms race. Futuristic applications.

Biometrics Best Practices and Applications
Abstract: In a 2000 paper, "The problematic unity of biometrics", in the journal,
Biometrics, Stephen Stigler wrote, "Our modern subject of biometry is amazingly
diverse; so much so that the question could be raised as to whether or not it has
sufficient unity to constitute a single discipline." Even in our very limited subset of
biometrics, that of automated human recognition, the received paradigms (what are we
doing?) are as varied as the applications -- to the point of asking, "Are we practicing a
single discipline?" Under the title "Biometric Best Practice and Applications", this
tutorial will look at the unifying principles that can organize our thinking across a wide
variety of applications of automated human recognition. Specifically, we will look at
some traditional and untraditional applications in the fields of forensics, identification
and access control, and the attempts by the multiple international standards
communities to arrive at unifying "best practices" in vocabulary (ISO/IEC
2382-37), testing, and reporting (19795-1 and -6) to help us create an identity as
practitioners of a single discipline.
