Ans:
3) A biometric modality is nothing but a category of a biometric system depending upon the type of human trait it takes as input.
4)
Verification Systems
Verification systems seek to answer the question “Is this person who they say they are?” Under a verification system, an individual presents himself or herself as a specific person. The system checks his or her biometric against a biometric profile that already exists in the database linked to that person’s file in order to find a match.
Verification systems are generally described as a 1-to-1 matching system because the system tries to match the biometric presented by the individual against a specific biometric already on file.
Identification Systems
Identification systems are different from verification systems because an identification system seeks to identify an unknown person, or unknown biometric. The system tries to answer the questions “Who is this person?” or “Who generated this biometric?” and must check the biometric presented against all others already in the database. Identification systems are described as a 1-to-n matching system, where n is the total number of biometrics in the database. Forensic databases, where a government tries to identify a latent print or DNA discarded at a crime scene, often operate as identification systems.
5) Failure can be due to physical differences, to lack of training, environmental conditions or ergonomics.
6)In some applications, biometrics may be used to supplement ID cards and passwords thereby imparting an additional level of security. Such an arrangement is often called a dual-factor authentication scheme.
7)Iris is formed in the early stages of an individual’s life and once it is fully formed its texture remains stable throughout a person’s life. The iris of the eye has a distinct pattern and iris recognition has been found to be a highly accurate biometric system.
