There was no pretense; their reactions to the sometimes bizarre situations set up by the Candid Camera staff were genuine and funny.
Although the cards are still kept on file, the computerized fingerprint records for more than 33 million criminals can be accessed in a matter of seconds.
Biometrics is the tool they are using. One in 17, people in the U. Wittman and Patrick M. In these cases, should authorities violate civil liberties with additional and more invasive searches? In the field of biometrics, fingerprinting is the oldest and, to date, the most successfully applied technique.
