According to the passage, technologists and governments ----.
The ability to recognize people automatically by
analyzing bodily characteristics such as
fingerprints, faces and eyeballs, collectively
known as biometrics, has long been a goal of
technologists and governments alike. Plans for
large-scale projects to incorporate biometric scans
into passports, identity cards and visas are now
under way in several countries. Since January 5th
the US has been scanning foreigners from
particular countries as they arrive at its airports.
Both the US and Europe plan to start issuing
biometric passports as soon as next year.
Biometric identity cards are being adopted in
Hong Kong and Oman, and Britain plans to follow
suit. Biometric technology has been around for
quite a while, but has not been widely adopted, for
good reason: while it can improve security in
some situations, its costs more frequently far
outweigh its benefits. Even the most advanced
systems falsely reject a small proportion of
legitimate users, and falsely accept illegitimate
ones. At best, the introduction of biometric identity
documents will produce a marginal increase in
security, at enormous cost. But at worst,
biometrics could, in fact, reduce security in
several ways.
