ABSTRACT
Although more and more biometric applications have emerged in
the market, many people are still skeptical about this technology.
This lack of trust mainly springs from security and privacy concern.
It is true that current biometric technologies are far from perfect,
although some of them can already achieve 99.99% accuracy. First
of all, people are worried that their biometric information could
be stolen by some bad guys and be used to invade into their
personal accounts. For example, fingerprint can be obtained from
the things we touch every day; face and iris information can be
directly obtained by taking a photo of one’s face or eyes. Once the
information is lost, there is no easy way to recover it as reissuing a
password. Moreover, there are still no complete laws or regulations
to protect the privacy of biometric data, which makes people feel
uncomfortable and intrusive while furnishing these data. Also,
standards for some biometric modalities are still missing, such as
the iris, which prevents their relevant technologies from spreading
widely. Last but not least, the prices of some biometric devices are
still very high, which makes them difficult to be acquired in the
market. In this chapter, we discuss the possible solutions to these
problems.
