BiometricMethods

Biometricmethods are used for recognition and access control. They identifyindividuals in groups based on human characteristics. Biometricidentifiers, which are used to label and describe individuals, areclassified behavioral and physiological characteristics.Physiological ones rely heavily on the shape of the body forinstance, face recognition, DNA, retina, body odor, iris recognition,and palm veins. The behavioral features include voice, gait, andtyping rhythm. Out of the different biometric systems, Irisrecognition is most superior whereas the finger recognition is themost problematic.

IrisRecognition

Irisrecognition uses mathematical model recognition techniques on imagesof one of the iris. It is considered the most accurate and fastestmethod. Notably, it captures the photos of the iris and maps thepattern to verify one’s identity. The method is regarded superiorbecause it focuses on the eye, which is a highly-protected organtherefore, it is easy to get an actual identity. The chances for afalse identity match are considered low. Every day, more than 100trillion iris recognitions are carried out globally, an indication ofits universal preference (Burge &amp Bowyer, 2013). Factors such asmedical surgeries have been argued to affect the color and shape ofthe iris, but its texture remains intact. Iris technology can betermed superior because it involves taking a photo of the eye withoutthe participant having to touch anything or tamper with the results.

FingerRecognition

Fingerrecognition is considered a flexible system, although it has itschallenges that make it among the least popular systems. Each of thehuman fingers has a unique type of vein for recognition (Meng, Yang,Yin &amp Xiao, 2012). As people age, the fingerprints tend todeplete, thereby making the finger recognition unreliable to detectidentity. The nature of blue color jobs also affects fingerprints andmakes it difficult to rely on it as a system of verification. It isfeasible for two people to have identical fingerprints technically,thus, posing a problem to the method.

Conclusion

Behavioraland physiological characteristics classify the different types ofbiometrics to systems that are used. Iris system is considered anaccurate and fast method of identification while the fingerrecognition tends to be problematic due to its lack of accuracy.However, it is notable that in as much as the iris system isconsidered superior, it has its challenges just like any other. Onthe other hand, the fingers recognition system can be dated from wayback, and it is still being used in many countries.
