Using the Body for Identification
13 biometric --- pertaining to a measurement of physical characteristics 13 identification --- the act of determining who someone is 16 fingerprints --- unique markings on the tips of the fingers 21 physiological --- having to do with physical or chemical properties of a living thing 23 iris --- the colorful portion of the eye surrounding the pupil Track 7 25 30 35 40 45 50 55 29 signature --- a mark representing a person’s name, as written by that person 38 verification --- the act of making sure something is true 44 forge --- to imitate dishonestly; to try to pass off something fake as something real 47 ethical --- moral 50 privacy --- the state of being private are unique to individuals, such as their voices or the way they type. The classic behavioral biometric is the signature. Signatures are used as a guarantee, but with obvious problems. Signatures can be copied, for one thing. Also, people don’t usually scrutinize a signature until a problem is apparent. A person’s voice might be more difficult to mimic. In fact, voice recognition systems do more than just recognize the voice; they recognize the way a person talks. There are subtleties in the way a person speaks that would be very difficult to imitate. Typing patterns, likewise, would be very difficult to observe to the point of mimicking them. Biometric identification has two potential uses—identification and identity verification. Identification occurs when biometric information is used to discover the identity of the person it belongs to. Again, fingerprints at a crime scene would be an example. Identity verification is the process of making sure a person is who he or she claims to be. Today, we use passports to verify our identity when crossing borders. However, passports can be stolen or forged, while an effective biometric identification system would be difficult to fool. It would be much more difficult to forge a fingerprint or an iris than it would be to forge a passport. There are also ethical considerations in developing biometric identification technology. It has the potential to protect consumers when engaging in trade as well as to identify would-be criminals before they can do any harm. However, some worry that individuals’ privacy would be in jeopardy if personal information were to get into the wrong hands. Another danger is that personal information could be abused by authorities. When governments have access to people’s personal information, they can use it to control the population. It goes without saying that people’s freedom and right to privacy will have to be protected as technology advances. Reading Time _______ minutes _______ seconds 607 words |
