Advantages of Biometric sensor | Disadvantages of Biometric sensor

This page covers advantages and disadvantages of Biometric sensor. It mentions Biometric sensor advantages and Biometric sensor disadvantages.

"Biometrics" is the term which refers to domain related to body measurements and related calculations. The transducer device which changes biometric characteristics (e.g. fingerprint, face, voice etc.) of a person into electrical signal is known as biometric sensor. It is used for wide variety of applications viz. fingerprint authentication, voice recognition, facial recognition, retinal scanning etc.

Biometric Identification Process

The figure-1 depicts biometric identification used for fingerprint. There are three processes involved viz. fingerprint scanning, matching and identification. One of the major application widely used is in mobile phone. Biometric sensor allows only authorized owners to unlock the mobile. Samples of authorized persons, who would like to use mobile phones are stored initially. Later user has to just place his/her finger on the place where sensor is located on the mobile screen and it gets unlocked. This happens when the pattern matches with any one of the stored samples.

Advantages of Biometric sensor

Following are the advantages of Biometric sensor:
➨It is widely used in mobile phones to allow authenticated persons to use it.
➨It provides very high level of security as person is required to be present for identification with the help of biometrics.
➨It is very easy method as it does not require one to remember passwords or PIN codes any more.
➨It helps in identification of criminals and hence used for credit cards, door locks, ATM, airport security, border controls, database access etc.
➨It is very reliable technology.

Disadvantages of Biometric sensor

Following are the disadvantages of Biometric sensor:
➨There is possibility of fraud by presenting fake image patterns to sensor devices which need to be cautioned to avoid such incidence.
➨Vendors should be compliant to follow biometric processes very accurately. Proper training is a must.
➨The method has higher false rates if live biometric samples are not presented properly.
➨There are various cultural issues in countries such as Japan, North America etc.
➨Voice recognition is not viable in settings where user must remain silent. Facial recognition does not work well in low light condition.
