Accuracy And Integrity
With
any security system, users will wonder,… can fingerprint
recognition system be beaten? In most cases, false negatives (a
failure to recognize a legitimate user) are more likely than
false positives. Overcoming a fingerprint system by presenting
it with a "false or fake" fingerprint is likely to be a
difficult deed. However, such scenarios will be tried, and the
sensors on the market use a variety of means to circumvent them.
For instance, someone may attempt to use latent print residue on
the sensor just after a legitimate user accesses the system. At
the other end of the scale, there is the gruesome possibility of
presenting a finger to the system that is no longer connected to
its owner. Therefore, sensors attempt to determine whether a
finger is live, and not made of latex (or worse). Detectors for
temperature, blood-oxygen level, pulse, blood flow, humidity, or
skin conductivity would be integrated.
Unfortunately, no technology is perfect--false positives and spoiled
readings do occur from time to time. But for those craving to break
free from the albatross that the password has become as both a
security and time-management issue fingerprint scanners are worth
looking into. It is estimated that 40 percent of helpdesk calls are
password related. Whether incorporated into the keyboard or mouse,
or used as a standalone device, scanners are more affordable than
ever, allow encryption of files keyed to a fingerprint, and can,
perhaps most importantly, help minimize stress over that stolen
laptop.
