Currently included in this program is the "technical" program, schedule of invited, topic contributed, regular contributed and poster sessions; Continuing Education courses (August 7-10, 2005); and Committee and Business Meetings. This on-line program will be updated frequently to reflect the most current revisions.

Title: Challenges for Statistical Scaling of Biometric Authentication
Author(s): Edwin P. Rood*+
Companies: Independent Consultant
Address: 912 Golden Bell Place, Lexington, 40515, United States
Keywords: biometrics ; authentication ; recognition ; scaling ; modelling ; prediction
Abstract:

Advances in information technology, including image analysis and data management, have made possible the widespread use of measurements of human physiological and behavioral characteristics for authentication or recognition. The automated use of such measurements for verification of identity (the "one to one" matching) and for identification of identity (the "one to many" matching) is denoted by the term "biometrics." This meaning of the term should not be confused with the traditional reference to the development of statistical and mathematical methods applicable to data analysis problems in the biological sciences, although the two fields can be related. Measured physiological characteristics include fingerprints, palm prints, face, and iris. Although these characteristics are believed unique to each person, practical implementation of biometrics produces images of varying quality that lead to uncertainties in the match between the unknown biometric and the target biometric. Furthermore, biometric systems include variables associated with human behavior and with the associated hardware and software.
