As with all electronic security systems, using a biometric verification process has its benefits as well as its downfalls.
The largest advantage of a biometrics system is of course the convenience of using your body or a personal characteristic to gain entrance to certain secure areas. There is no need to remember special codes, passwords or carry access cards, ID books or driver's licences, as all information pertaining to you and these formalities will be available on a central database with the recognition of a thumb print or a scan or some sort. It is also much harder to counterfeit personal details than a physical object such as an ID card.
If a person forgets their password or secret code, it can be reset or reissued without much difficulty, with biometric electronic security systems, this may not be so simple. There are, however a number of concerns relating to how biometric electronic security systems may actually invade an individual's privacy. Using a finger print reader as an electronic security device is not as evasive as having your retina scanned for example. Some people may not feel comfortable knowing that their DNA or personal information is stored somewhere beyond their control.
If the electronic system storing an individual's personal data is not secure and this personal information is stolen or hacked into, it may cause devastating effects on a person's life. If the electronic security system is flawed and suddenly does not recognise an individual, this person may lose his or her identity completely.
Criminals may use the information stored on advanced electronic security systems to commit crimes and compromise the safety and security of innocent citizens. Crimes may also become more severe and unnecessary. Criminals may be forced to harass or injure individuals unnecessarily in order to gain access to a home that uses fingerprint recognition to unlock the doors for example.
Countries may opt to share the information gathered when creating biometrics security systems, which may violate privacy, safety and constitutional laws of certain countries.
