Disadvantages Of Biometric System

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.

This technology is mainly used for identification, access control and for identifying individuals that are under observations. In computer, biometrics refers to the authentication. It can be either an ‘identification’ system or a ‘authentication’ system.

Biometric recognition, or biometrics, refers to the automatic authentication of a person based on his or her physiological or behavioural characteristics (Jain, Bolle, and Pankanti 1999a; Maltoni, Maio, Jain, and Prabhakar 2003). One of the most important technologies which acts as a human being identify required purpose. Nowadays there were great progresses in technology of access for companies which it using human being body to identify the identity of the person. In the past Human beings used fingerprint to identity for signature. Biometric technology looks like a revolution for modern society for example, Iris and AFIS (Automatic Finger

Recognition requires the system to search through many sets of resources stored and choose the one that corresponds to the unknown person presented. Various types of biometric systems are used for real-time identification; the most popular are based on face recognition and fingerprint recognition. However, there are other biometric systems that utilize iris and retinal scan, voice, gesture recognition, and hand geometry. Biometric technologies are becoming the basis for a wide range of solutions for personal identification and verification of high security. The basic idea behind biometrics is that our bodies contain unique properties that can be used to distinguish it from others. A biometric system is essentially a

Biometric methodologies emerged into existence in 1858 by use of recording hand images for identification purposes. From 1858 to 1896 studies progressed in the identification of individuals by hand geometry, a person’s measurements, and fingerprints. From the year 1936 to 1985 biometric studies proceeded for iris pattern, face recognition, acoustic speech, written signature, and hand identification. Patents for hand and iris identification became a reality 1985 to 1986 and in 1988 the first semi-automated facial recognition system was deployed. By 1991 face recognition is automated with the ability of detecting faces in real-time. By the mid to late 1990’s biometric methodologies evolves and is integrated into technology allowing the practice of fingerprint, palm systems, and iris identification to become more reliable with increased automation capabilities. Studies therefore increased and biometric technology became even more advanced in the early 2000’s up until today’s time.

Biometrics are automated methods of recognizing a person based on a physiological or behavioral characteristic. Among the features measured are; face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. Biometric technologies are becoming the foundation of an extensive array of highly secure identification and personal verification solutions. As the level of security breaches and transaction fraud increases, the need for highly secure identification and personal verification technologies is becoming apparent.

In recent years, it has become more and more popular for biometrics to be used as an authentication tool (e.g. mobile phone passwords using fingerprint scan, room entries using fingerprint or iris scan, etc.) because it is believed to be more reliable and genuine than the traditional recognition systems (e.g. phone passcodes, keys, tokens/tubs, etc.). This is mostly because every person has their unique biometric features that cannot be mimicked e.g. the ridges of a fingerprint is so unique that even dust or water on a person’s finger could change the way the ridges are read, the structure of the iris has its different structure is every individual person, Palm print is also varies from person to person with size or tiny features, facial recognition software’s are also a perfect example because facial structures differ from person to person hence why it is almost impossible for two people to look

The second operational mode of biometric authentication system has these two following modes. First one is verification mode and the second one is identification mode. In verification mode the system performs a one-to-one comparison between the biometric trait captured and the specific template available in biometric database for the verification of individual. Verification of individual mean the person which is declared is same or not

Here it was used to identify children by using ink to print their fingerprints (Bhattacharyya, Ranjan, & Alisherov, 2009). Later on, in 1890 biometric authentication methods then resurfaced and was used to identify criminals by looking at their body structure and the sizes of certain parts (Bhattacharyya, Ranjan, & Alisherov, 2009). This method of identifying criminals was proven to give false information and therefore was no longer used (Bhattacharyya, Ranjan, & Alisherov, 2009). As years went by, signature biometric authentication methods were developed in the 1960’s and 1970’s but was not really used as a method of identifying people (Bhattacharyya, Ranjan, & Alisherov, 2009). As a result, fingerprinting was seen as the most common biometric authentication method (Bhattacharyya, Ranjan, & Alisherov,

Multimodal biometric system solves the problem of non universality which is occoured in unimodal biometric systems.For example,if the persons cut finger prevents him from successfully enrolling into a fingerprint system,then the availability of another biometric trait,say face,can be used in the inclusion in the biometric system.

For iris or retinal scanning applications, users might find it very intrusive. Users might also have the concern for the safety of the eyes throughout the iris or retinal scan. Furthermore, databases used to store user identification data will soon be very large which might form a potential threat. For scanning retinal/iris characteristics and storing wide range of database, biometrics system requires new and modern technology. Therefore, the price for equipment can also be expensive. Finally, a lot of people remain concerned about biometrics technology in different aspects such as: security, adaptability to rate of change in life, scalability, accuracy, privacy and others.

As the world evolved into a more electronic society, the possibility of using microprocessors to automate identity verification began to occupy the minds of individuals in both the military and commercial sectors. This led to the development of the hand geometry reader. It was a large and clunky device, but it worked. Refinements later yielded a much smaller and considerably enhanced hand geometry reader that became one of the cornerstones of early biometric industry. At the same time fingerprinting verification was being steadily improved to the point where it became a reliable method for verification. It wasn't until recently that there has been interest in iris scanning and facial recognition techniques, which offer the potential of a non-contact technology. The last decade has seen the biometric industry expand from a handful of specialist manufacturers, to a global industry poised for tremendous growth as large scale applications start to unfold.

In today’s world transformation of data very securely and information security are the most important categories for the organizations to follow or else the information can easily be taken away by the enemies. In olden days the organizations used to follow the encryption and decryption for the transformation of data securely which is known as cryptography. In cryptography the security of data depends on how strong the encryption and decryption are said to be used. But it is not very easy for the sender and receiver to recall all the passwords. So avoid those difficulties crypto-biometric is used which is the combination of biometric and cryptography. The biometric is a technology that identifies humans with their body uniqueness like fingerprints, face prints and voice patterns for the validation purposes. In recent year’s most of the analysts, trying to eradicate the password identification and using the biometric. The combination of cryptography and biometric can eliminate the recall of passwords because the information can be used only by the identified person. But there are some of the problems that are faced in the biometric. The biometric system which contains the information should not reveal any biometric features. It should also have the flexibility of converting the varied data in to the fixed. So, the data cannot be revealed to the unauthorized person when it was transmitted. Therefore, the result of Fingerprint based crypto-biometric system for network

Biometrics is a computerized strategy for recognizing an individual focused around physiological or behavioural trademarks. Among the features measured are face, fingerprints, hand geometry, signature, iris, retinal, vein, and voice. Biometric information is independent and unique from individual data. According to Du (2013) “Biometric systems use a person’s physiological, behavioural, and psychological characteristics to perform human identification”. There are unique points of interest with biometric innovation, for example, face recognition, simple access and numerous like this. On the other hand, a few obstacles additionally emulated with these points of interest, for example, noisy information, accuracy, illumination issues in concern
