title: Biometrics: Your Body and the Science of Security
author:  Maria Birmingham 
description: Gr 5 UpBiometric identification uses technology to collect information about the unique physical and behavioral characteristics of individuals in order to authenticate their identity. There are more than seven billion humans on our planet, so it makes sense, according to Birmingham, to ditch the ubiquitous and easily hackable password method of identification in favor of new technologies. Written in a friendly and accessible style, chapters are short and full of vibrant cartoon illustrations that add some levity to the subject matter. (Frankenstein's face appears in the lineup in the "Facial Recognition: Face the Facts" sidebar.) Birmingham explores established and emerging biometric identification methods, explaining how fingerprint, hand geometry, and facial recognition work and where they are already being used. Iris, retinal, voice, and vein scanning are also covered. The future of biometrics is wide open. There might come a day when we are identified by our tongues, ears, gait, or even scent! For each method of biometric identification there is a highlighted sidebar detailing the type (physiological or behavioral), the difficulty involved in collecting data for the biometric, and how reliable and secure it is. Areas of concern such as issues of privacy and potential malfunctions of biometric systems are addressed. VERDICT The use of biometrics in the science of identity authentication is here to stay. This compelling and comprehensible overview of the field is recommended for middle school readers.Ragan O'Malley, Saint Ann's School, Brooklyn

  About the Tutorial 
  This tutorial provides introductory knowledge on Biometrics. By accessing this 
  tutorial, you would get sufficient information about the basics of biometrics and 
  different biometric modalities such as physiological, behavioral, and combination 
  of both modalities.  
  This tutorial also provides a glimpse of various security issues related to biometric 
  systems, and the comparison of various biometric systems.  
  Audience 
  This tutorial is prepared for the students at beginner level who aspire to 
  understand biometrics and various biometric systems. It would also be useful for 
  enthusiasts in the fields of Electronics, IT security, and Biology.    
  Prerequisites 
  Biometrics is an advanced concept and we cannot claim that a reader can sail 
  through this tutorial without having any grip over some basic knowledge of 
  Computer Science, and Mathematics. Knowledge of Science is a plus.
