Identify the correct disadvantages of each biometric method


A :

 Biometric techniques:

Biometric gadgets are numerous sorts, however significantly there are five kinds of biometrics security which are usually utilized. Biometrics is essentially the acknowledgment of individual character that are novel to every human, which incorporates facial acknowledgment, fingerprints, voice acknowledgment, retina filters, palm prints, and more Biometric innovation are utilized to guard the gadgets in the most ideal manner to guarantee that individuals avoid their important resources and data, and will find that utilizing any of these five biometrics security, gadgets is an extraordinary method to protect things..

Types of Biometric methods

Facial recognition:


• Non meddlesome

• Cheap innovation.


• 2D acknowledgment is influenced by changes in lighting, the individual's hair, the age, and if the individual wear glasses.
