Advantages

Biometrics provide a  convenient  and  increased security and reduce or minimize  fraud.   Problems such as lost Identity cards   or forgotten passwords are eliminated  with the system  and reduce password and  attributed administration costs. Biometrics  replaces hard to remember passwords  which may be stolen, shared or observed.  Another advantage is  biometrics integrate a wide range of biometric solutions and technologies, customer applications and databases into a robust and scalable control solution for facility and network access. With biometric technology it is possible to know who did, what , where and when and helpful to curb  terrorism.  Biometric offers  cost savings in areas such as loss , prevention or time and attendance. Biometrics can link an individual to a transaction or event.

Disadvantages

The finger print of those people  who are working in the  chemical industry are frequently affected and   for that reason  such companies should not use the finger print mode for authentication.  With regard to voice recognition, It is  with the age the voice of a person differs  and when person has a cold or flue or throat infection  the voice changes   and there are too much noise in the environment  this system  will not be able  to identify  accurately. A person’s voice can be easily recorded and used for unauthorized PC or network.  As such this  system is not  operational all the time.

In fingerprints it  can make mistakes with the dryness or dirty of the finger’s skin, as well as with the age and this method is not appropriate with children, because the size of their fingerprint changes quickly.

Signature verification is designed to verify subjects based on the traits of their unique nature. As a result, individuals who do not sign their names in a consistent manner may have difficulty enrolling and verifying in  verification.

In retina  scanning in  people who are affected with diabetes the eyes get affected  and as a result  there are differences  and  difficult  for  correct authentication. Retinal Scanning  has the stigma of consumer’s thinking it is potentially harmful to the eye. This method is not user friendly and time consuming.

In hand geometry It is not valid for arthritic person, since they cannot put the hand on the scanner properly  and it does not recognize living tissues.  Also scanning the same position  and  this is not hygienic  method.

Facial recognition is time consuming and  lot of memory for the data to be stored.

In general all Biometric methods are  considered  very expensive.

Views

In today’s world of heightened sensitivity to security,  organizations  finds itself at the front line of this conflict   necessary to provide  security to its customers  and staff in their entire stay will be peaceful and problem free. To achieve this goal,  companies  deploy a very structured  biometrics. The system revolves around a core biometric verification system which, when deployed in any place  provides best in class security.

Point of Views of Users

General public  are being conditioned to give up their privacy and independence in exchange for the “safety”.  Some  innocent  men, women and children  have already   been misused their faces with scanning cameras. In the past only criminals were fingerprinted  but  it is argued in the near future people will have to biometrically scan their body parts to get  driving license, to get a job  to have a bank account etc etc. It is said that with biometrics technology  world is heading towards dictatorship.
