Advantages And Disadvantages Of Data Security Using Biometric

Biometrics technology aims at utilizing major and distinctive characteristics such as behavioral or biological, for the sake of positively indentifying people. With the help of a combination of hardware and specific identifying sets of rules, a basic human attribute, automated biometric recognition mimics to distinguish and categorize other people as individual and unique. But the challenges surrounding biometrics are great as well.

The thing with biometrics is that it works great only if the verifier can verify two things: Firstly, that the biometric to be used has come from the intended person at the time of verification, and Secondly, which the biometric should match with the master biometric entry in the file database. If the system can't do that, it can't work. Biometrics are good in uniquely identifying the people, butat the same time they are not secrets and cannot be trusted [1].

During the identification phase, the user puts the finger on the same sensor, generating a new fingerprint image or template called query print. Minutiae points are carried out from the query print, and the matcher module compares the set of query minutia with the stored minutia templates or image in the enrollment database to find the number of similar minutia points. Because of variations present in finger placement and pressure applied to the sensor, the minutia points take out from the template and query fingerprints must be lined up, or submitted before matching. After line up the fingerprints, the matcher decides the number of pairs of matching minutiae-two minutiae points that have similar location and directions. The system decides the user's identity by comparing the match score to a

30. What is the process of confirming a user’s identity by using a known value, such as a password, pin number on a smart card, or user’s fingerprint or handprint in the case of biometric authentication? Authentication

Biometrics is a method of identifying an individual based on characteristics that they possess, typically physiological features such as a fingerprint, hand, iris, retina, face, voice, and even DNA. Some methods of biometrics security even use multiple physiological features or multimodal biometrics to provide superior security than a single form of biometrics can provide. Why are biometrics important in the field of information security? Biometrics provide a remarkable amount of security for information because biometrics are unique to each person, and thus cannot be lost, copied, or shared with another individual. This security allows for biometrics to provide a means to reliability authenticate personnel. The importance of biometrics can be further divided into the history of biometrics and why it was devised, past implementations of biometrics, current implementations of biometrics, and future implementations of biometrics.

Biometric Authentication refers to the usage of software that looks for physical markers to allow access to a system. Some of the most commonly used physical markers are fingerprints, face-recognition, voice-recognition, and iris-recognition (Williams & Sawyer, 2015). As no two humans are exactly alike biometics are less likely to be hacked, although it is not impossible.

There many types of biometrics that are known to have success within organizations and government agencies. Some these types include smart card, fingerprint recognition, retinal/iris scanner, hand geometry, and facial recognition. All these types are known to be the most common types but one most also know that just like any other technology, each have their advantages and disadvantages. For example, smart card and fingerprint recognition are the most widely used due to them being cost effective and user friendly. The retinal/iris scanner are very secure but can be expensive to some. Although these technologies can be combined such as the smart card and fingerprint recognition, such as by having an individual insert has smart card into the reader which then will require that individual to place his/her finger on a scanner for a reading. Now let’s use the technologies in a example for access control of the facility that may be best to improve security while also considering cost. First is to implement the smart card which contains an integrated circuit chip. These smart cards work like an identification card but contain a circuit chip that allows for the storing of personal information, photograph of the person and biometrics like

In order to protect users of computer systems and to secure network-based transactions, demand is increasing for improved user authentication procedures to establish the identity of an actual user and to bar access to a terminal to anyone who is unauthorized. Personal identification using biometrics, i.e., a person’s physical or behavioral characteristics has come to attract increased attention as a possible solution to this issue and one that might offer reliable systems at a reasonable cost. While traditionally this technology has been available only with such expensive, high-end systems as those used in law enforcement and other government applications, today many personal–level applications have also become

Face recognition is another biometric technology. Face recognition uses the same technology that iris recognition uses. For face recognition, a camera takes several images of a person to find out who it is. Face recognition differs from all of the other biometric technologies because the person that is in the picture does not have to cooperate with the process. In all of the other technologies it requires the people to actively participate in the process. In face recognition, the image can be taken without the person even knowing that it took place.

Biometrics can be used for either identification scheme or verification. For example the use of facial recognition allows a system to identity a person without his or hers knowledge or permission. Devices like these have been tested at security checkpoints, casinos, airports and could be used to identify a terrorist or wanted criminal. Also the use of biometrics in verification. For example instead of using a password to grant access the system uses a fingerprints or the scan of an

Biometrics is a term that refers to the broad amassment of various human characteristics. In computer science, biometrics authentication is used for access and a form of identification. Biometrics can also be used to survey and identify individuals in groups. Statistically, biometrics are unique and measurable to only one individual. When biometrics are used in authentication they can be broken down into two groups of measurability, physiological characteristics and behavioral characteristics. Physiological characteristic can be, but are not limited to, Biometrics that consist of a person’s Deoxyribonucleic acid (DNA), fingerprints, face, hands, eyes, ears or even odor. The second of the two characteristics, are the behavioral

Biometrics Technologies is the biological identification of a person, from their eyes, voice, hand prints, fingerprints, retina patterns and handwritten signatures (Tavani 214).

Biometrics are automated methods of recognizing a person based on a physical or behavioral characteristic (2001). Essentially, biometric security technologies are used to accurately identify individuals on a unique trait. The most common biometric security techniques used currently are: signature

Biometric technologies are getting better and finely tuned. The rate of false readings and errors has sharply fallen. However it still requires careful consideration and planning to implement a biometric identification system. They are most costly and complicated to implement as compared with other authentication systems. A proper evaluation of the system is important before purchasing any biometric system. A thorough risk analysis is necessary. In many cases biometrics may be overkill. Biometrics must be used if there is high level of risk involved. Customer acceptance is also important when logging on to company websites. Home users might not be ready to install biometrics on home computers for online banking.
