Sensor Biometrics

What is a biosensor?

• A detecting device that combines a transducer with a biologically sensitive and selective component.

• A device that measures only chemical compounds present in the human body.

• A device that is not cost-effective compared to traditional analytical techniques.

• A device that cannot measure compounds present in the environment.

What is the purpose of a biosensor?

• To measure compounds present in the environment, chemical processes, food and human body.

• To measure only chemical compounds present in the human body.

• To provide an expensive alternative to traditional analytical techniques.

• To measure compounds present in the environment only.

What is a biometric?

• An automated method of recognizing a person based on a physiological or behavioral characteristic.

• A device that measures the environment.

• A device that measures compounds in the human body.

• A device that is not accurate.

What are the features measured in biometrics?

• Face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice.

• Chemical compounds in the human body.

• Only the voice of a person.

• Only the fingerprints of a person.

What is the main advantage of using a biosensor?

• Low cost compared to traditional analytical techniques.

• High cost compared to traditional analytical techniques.

• Inaccuracy in measuring compounds.

• Only measuring compounds in the environment.

Can biometric templates be reverse-engineered to recreate personal information?

• No.

• Yes.

• It depends on the type of biometric.

• It depends on the person being measured.

Can biometric templates be stolen and used to access personal information?

• No.

• Yes.

• It depends on the type of biometric.

• It depends on the person being measured.

What is the difference between a biosensor and a biometric?

• A biosensor is a detecting device while a biometric is a method of recognizing a person.

• A biosensor measures only compounds in the human body while a biometric measures physiological and behavioral characteristics.

• A biosensor is not cost-effective while a biometric is cost-effective.

• A biosensor cannot measure compounds in the environment while a biometric can.
