As technology becomes increasingly ingrained in our daily lives, new forms continue to emerge all the time. One novel example that you might have heard about is biometrics. This technology is defined as a means of identifying and authenticating a person using biological characteristics. Common biometric types include fingerprint mapping, facial recognition, and retina scans. Biometrics can be used to either authenticate a person¡¦s identity or identify individuals. Biometric authentication involves comparing a person¡¦s data with their previously stored information. In contrast, biometric identification involves comparing a person¡¦s data to that of others in a database to determine their identity.
Biometrics can be classified into two categories: physiological measurements and behavioral measurements. Physiological measurements can be further divided into two sets. Morphological identifiers refer to physical characteristics unique to an individual and that are unlikely to change, including fingerprints and eyes. For a biological analysis, DNA, blood, or urine samples are used. Contrary to physiological measurements, behavioral measurements look at a person¡¦s actions, such as how they talk, walk, and even sign their name.
While biometrics might seem like a new, cutting-edge technology, it has actually been used for over 100 years. Around the turn of the 20th century, police forces in cities like London and Paris began using fingerprints to identify criminals. Law enforcement remains one of the most common fields where biometrics is employed. This includes using advanced technology like Automatic Biometric Identification Systems that can find criminals based on photos. Biometrics has also become widely used for immigration and border control. Many airports now have passengers scan their faces and fingertips upon entry and exit.
While advancements in biometrics can be helpful, there are still concerns. Not all biometric tests are 100% accurate, and some facial recognition programs have been known to misidentify people of color more frequently. Hopefully, as this technology further develops, it will be used in ways that prioritize beneficial applications for society.
1.According to the passage, how does biometric authentication differ from biometric identification?
