PartTwo: Completion (2X7=14 points)

1. Handprint recognition scans the _____________________________, not the handprint..

2. EPIC criticized Disney’s move based on the legal principle known as “________________,” which can be encapsulated as whether the amount and type of information being collected equals the level of security being sought.

3. The _________________ is by far the most “counterfeit resistant” biometric ID/verification technology available today..

4. The Israel project “Basel” incorporates both _________ scan and ___________ scan;.

5. Where hand geometry does have an advantage is in its ____________________, which measure the likelihood that a user is incapable of enrolling in the system.

6. Based on the textbook, perhaps the most frequently used and most successful hand-scan project is the ____________________________________________________________ project.

7. Among biometric technologies, Sandia reported that __________________ had the highest user acceptance of all devices tested.

PartThree: True/False (1X10=10 points)
1. Because human hands are unique, hand geometry can assure dynamic verification.

2. In a recent study, the National Academies of Science found that while a person’s finger geometry is indeed far less distinctive than his or her fingerprints, hand or finger biometrics is indeed suitable as an identifier for a wide variety of circumstances, where one in a thousand uniqueness is sufficient.

3. With a high level of security, ease of use, and nonthreatening technology, hand geometry has become the most widely accepted biometric technology in use today.

4. Hand geometry alone is able to perform one-to-one and one-to-many identification.

5. Hand geometry is a relatively accurate technology. It draws on as rich a data set as finger, face, or iris biometrics.

6. During an enrollment of hand geometry, the unit’s internal processor and software convert the hand image to a nine-byte mathematical template, which is the average of the three readings.

7. Individuals need to register on each device in hand-scan applications that include a large number of access points.

8. The National Center for State Courts indicates that the use of hand geometry is enough to identify an individual.

9. Influences such as swelling or injury can disguise the basic structure of the hand.

10. There is absolutely zero invasion of privacy in the 3D picture of two fingers.
