  1. BIOMETRICS By Mona Lisa Walters Wiki.gc.maricopa.edu CIS 105 Poster Session No. 4

  2. Biometrics • Scientific method of verifying a people’s identity using their physical attributes • Five main types are: • Face recognition • Fingerprint scanning • Hand geometry • Eye Biometrics • Voice Verification

  3. Face Scanning • Measure the different features & bone structure • Need a good camera & proper software

  4. Fingerprint Scanning • Tiny ridges of persons’ fingers are stored in a tiny digital file & computer scans in seconds • Invariable – difficult to forge Disney World uses finger scanning

  5. Hand Scanning • Measures the length, width, thickness and surface area of hand • May be altered due to injury, disease, aging

  6. Eye Biometrics • Most promising form of identification • Iris scanning measures the patterns of lines and colors of the eye • Retina measures the membrane at the back of the eye

  7. Voice Verification • Measures the pitch, cadence, and tone • Pre-recorded and compare to their live voice • More variables • Limited to “backup” status

  8. Biometric ID System • Main operations – enrollment & test

  9. Enrollment/Registration • Sensor – the interface between people and the system • Pre-processing – removal of artifacts to enhance the input • Feature extractor – finding the true biometric pattern • Template generator – the extracted features are used to create a template • Then, the templates are stored, on a card or both

  10. Test Process • Matching phase – the obtained data is compared to the template • Application device – the output of the specified use or purpose

  11. Functions • Detect terrorist and criminals • Immigration purposes • Keep track of employees logging onto the computer systems • Improve efficiency and streamline payroll operations • Better than the traditional ID • Prevent identity theft

  12. Concerns • Disregards people’s privacy • There is no way to collect the biometrics of terrorists • Abuse usage of information • Danger to owners of secured items

  13. Course of Actions • Regulatory laws that will protect people’s privacy • Manufacturers self-imposed guidelines “bio-privacy” rules • People are made to be aware of the data to be collected and its purpose • Data minimization • Data must only be used for the purpose • Users can review and correct any incorrect data
