Question

Which of the following is a physiological biometric that could be used for authentication?
All the options
Gait
Voice Recognition
Signature
Facial Recognition

Answer 1

Answer:

Physiological characteristics are related to the shape of the body. Examples include, but arenot limited to fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina and odour/scent.

Answer 2

Answer:

Gait is the correct answer.

Explanation:

A simple biometric definition:

Biometric data is a biological measurement (or physical characteristic) that can be used to identify a person. For example, fingerprint mapping, facial recognition, and retinal scanning are all biometric technologies, but these are just the most popular options.

            Researchers claim that ear shapes, sitting and walking patterns, distinctive body odors, hand veins, and facial contortions are also unique identifiers.

• Biological biometrics uses traits at the genetic and molecular levels. This may include properties such as DNA or blood that can be assessed by taking a sample of bodily fluid.
• Morphological biometrics is about your body structure. Other physical features such as eyes, fingerprints, and facial features can be mapped for use in security scanners.
• Behavioral biometrics are based on patterns that are different for each person. When these patterns are tracked, the way you walk, talk, and even type on your keyboard can be clues to your identity.

Biometrics plays an increasingly important role in our everyday security. Even in twins, physical characteristics are relatively fixed and individualized.

• Each individual's unique biometric identity can be used to replace or at least augment password systems in computers, phones, rooms and buildings with limited access.

• Once biometric data is captured and associated, it is stored for matching against future access attempts.
• In most cases, this data is encrypted and stored on your device or on a remote server.
• A biometric scanner is hardware used to obtain biometrics for identity verification.
• These scans are checked against stored databases to approve or deny access to the system.

So biometric security means your body is the “key” to unlocking access.

Common examples of biometric security include:

• voice recognition
• fingerprint scan
• face recognition
• Iris detection
• heart rate sensor
