Examples of Biometric Devices

Technology and technological devices have been enhancing day by day. With this enhancement we have made more secure by the utilization of our trusted technological devices that keep our data safe from unauthorized access. Previously, people were using their computerized gadgets that usually provide data safety by getting a specific password from user. In this way, data can be accessed by only those persons who know about the password. It is the most popular method of keeping your important data and property safe from the unauthorized persons and is still utilized hugely. However, sometimes, when data is extremely precious that it is to be sanctioned and viewed by the owner only, then in such case, keeping password is not the authentic solution. Data must have to be secured and keep protected to make sure that it cannot be leaked or accessed illegally.

Fortunately, we are living in 21st century and have been circled by the latest technological input devices that possess bio-metric technology to resolve our security issues. Bio metric input devices authenticate the person's identity by personal characteristic verification. Thus it is made sure that the person is really the one who has all the rights to open the respective secured file. It might be possible that someone can steal your security password or view it secretly without getting your permission. Your important data and information can be leaked out if some unauthorized person gets to know about your password. Your password can be stolen; however, your personal identity cannot be stolen by anyone. A Bio-metric identification device analyzes biometric identifier which could be a person's behavioral characteristics, a person's finger prints, foot print, facial features, voice, eye patterns etc. By detecting person's identity, the software allows a user to access the required data.

How Bio-metric System Works?

Working strategy of a bio-metric security system is not that different from other computer operations. When a person's bio-metric information is entered by the bio-metric device, it converts this personal characteristic into digital code. Furthermore, this digital code is compared with the digital code stored in the computer system. The access is not granted to the person until both the codes match.

Examples of Biometric Devices

Different bio-metric input devices are used for entering bio-metric information of a user for security purposes. Some of the Examples of Biometric Devices are given below:

•  Finger print Reader

One of the most reliable and extensively utilized devices for biometric authentication is fingerprint reader. It’s considered among most helpful examples of biometric devices which get user's biometric information for keeping the necessary files secured and risk free. Every person have got unique finger prints, thus a fingerprint reader identifies the right person by scanning the curves and indentations of a fingerprint. It’s an inexpensive and reliable way of protecting our valuable data and important files from unauthorized access. Today, we have also got smart phones possessing the fingerprint readers for making our mobile data secure. Moreover, some latest keyboards and notebook computers have also fingerprint readers for logging on the computer using finger prints without entering user name or password.

• Biometric Facial Recognition System

This type of biometric security requires live face image of a person as input. The bio-metric facial recognition device then compares this live captured image with the image that is already stored in the system. The system won't allow the person to surpass if the image is not matched with the stored one. This is a foolproof method to secure any data, any building or department from unauthorized access.

• Hand Geometry System

This is one of the examples of biometric devices which consists of hand geometry system that recognizes the shape or size of the hand. It’s a kind of expensive biometric system for biometric identification that is mostly utilized by large organizations for security purposes. The user can give his identification to the system by placing his hand on a flat surface. The system gets the data by identifying the person's hand and let the user see his required data that has been secured by the respective device through biometric authentication.

• Voice verification system

One of the biometric input devices is "voice verification system” that collects person's bio-metric information in voice format. According to this bio-metric technology, the person who needs to surpass the bio-metric security will enter his voice as input which is compared with the one that has already been stored into the system for bio-metric authentication. In case of miss match, the user is not allowed to access the protected data or location. Large companies and well established organizations use these systems for ensuring attendance of their employees.

• Signature verification system

Similar to the previous ones, a signature verification system is also one of the useful examples of biometric devices. This device is basically developed to input the handwritten signatures as biometric information. Besides determining the shape of signature, a signature verification system can also measure the pressure and motion that is used to write the signature. For entering the signature, this system uses special pen and tablet.

• Iris Recognition System

This type of biometric input device uses iris recognition technology for reading patterns in the iris of an eye. These eye patterns are unique and thus any unauthorized person is not able to surpass the security system. Such costly biometric system is used most often, by government security organizations, large financial or military organizations.
