Biometrics Technology Review 2002
Abstract
The September 11, 2001 terrorist attacks in the United States have motivated renewed global efforts to secure national borders. Accordingly, Australian authorities have demonstrated an interest in mechanisms that support these endeavors. This report examines the state of current biometric research, covering the literature up to October 2002. The report characterizes the main categories of biometric techniques, with a focus on face recognition, which is the least intrusive but most effective means of applying filters at access points to the country. It describes the basic technologies inherent in the four major taxonomies used in identification methodologies. These comprise authentication and validation approaches, each based on one-to-one and one-of-many models. The report provides descriptions of the following biometric categories, including discussions of their strengths and weaknesses: fingerprint technologies that employ a number of different sensors (i.e., capacitive, optical, imaging infrared, ultrasonic, mechanical, hygiene) that produce two-dimensional maps of fingerprints; face recognition technologies in which maps of the face are analyzed, processed, stored, and used in the matching process; hand dimension, palm pattern, and vein pattern matching; iris and retina scanning; voice analysis; signature matching; keystroke filtering; DNA matching; ear shape matching; and work patterns, such as typing speed and choice of words in a document. Some applications of these biometric techniques include access controls to physical locations and computer systems and identification procedures in medical, military, and government domains. A table shows how each of the techniques studied compare with one another in terms of access control, surveillance, accuracy, reliability, error rate, false positives/negatives, security, stability, user acceptance, intrusiveness, ease of use, cost, strengths, and weaknesses.
