Necessity of Biometric Security System for Homes

Biometric Security System is a emerging technology that acquire much attention by houseowners. If you are looking for a safest and strongest security system, Dthree is the best option. Among the majority of the consumers, Security is the main reason for them to purchase Biometric security systems. As today smart phones are the basic standard access for all the biometric systems. Manual door locks are gradually being replaced with smart biometric Systems. The main advantage of Smart phone or remote devices are it enable the user to monitor/control the entire security system even if moving. So here cost never matters; Only the matter is Secure.

Biometric Security system is considered to be the best and one of the most secure system which can be installed to home, office, buildings etc. Biometric Systems are working on the basis of physiological and behavioral specifications. Physiological characeristic means the physical appearnce factors such as shape of the body, body parts like finger, iris etc. Where behavioral characteristics deals with behavior of a person. The database stored all the characteristic datas of the induvidual and they looks matching when the next login details appears on the system.

Working Principle of Biometric Systems

Biometric sysytem is a smart system that collects a biometric data, which can be behavioral or physical recogonition from a person and stored in a Database. And the device looks for the exact match which storedin the data base with the outside action. A biometric system contains a sensor, quality assessment unit, unit for matching and comparison and database.

Sensing Interface

Sensor Interface provides the link between the Biometric Control Unit and the user. This unit is mainly deals with the data transmission which the database composed of images, finger print, voice recogintion and more.

Data Transmission

An algoritham design is applied for strengthening the signals for improving the quality of the data. Because the data from the sensor unit must be evaluated before the further processing. The user have to re submit the data, if the data carries low quality. Then a set of feature is stored in the data base and this can be used for the estimation and extraction. Then the result will be stored in the system data base

How the data matching occurs?

In this section the unit is deals with comparison and matching process based on the data stored in the device. A matching function is enabled if the input and the the data stored in the device become same value. The values may be slightly vary, because its fully depend on the quality of the recieved data. After the matching process, the device makes a decission based on the input and the data.

System Database

Inorder to attain high security level, the device collects multiple samples or inputs, often found in facial recognition. The process of transimitting and recieving the data may be under the technician or automated. So for processing the biometric readings, the database stored all type of informations. In case if the input (may be finger print) is not matching with the data stored in the database even the input is provided by the same user, then the system deal with some other characteristics which already stored in the device.

Categories of Biometric Security Systems for Home

In this section, its deals with what are the various inputs or types of Biometric systems used for home. Mainly the Biometric systems works on two categories. That is Physical and Behavioral Characteristics. The physiological biometrics includes face identification, fingerprint, hand geometry, iris recognition and DNA. Whereas behavioral biometrics include keystroke, signature and voice recognition.

  • Fingerprint Protected Home

    In this category, the system stored the fingerprint of the user and the device records and analyse its features. The features means, arches, whorls, loops, furrows etc of the fingers. Matching of the fingerprint depends in three ways, such as minutiae, correlation, and ridge. To capture the fingerprints, present methods employ optical sensors that include a CMOS image sensor or CCD, solid-state sensors. Basedcon this the system allows the user to enter the home or not.

  • Face Recognition

    Its a application which used to verify a user based on the digital image by comparing and analysis of the facial features. Its a common system used for the home, building, banks etc. The device works with face features and it can identify around 80 nodal points on the human face. Social Medias like Facebook uses software for face recoginition to tag the users in the images.

  • Iris Recognition

    It is a type of biometric security systems, used to identify the people based on their iris features like single patterns in the region of ring-shaped surrounded the pupil of the eye. Generally, the iris has a blue, brown, gray or green color with difficult patterns which are noticeable upon close inspection.

  • Voice Recognition

    This method is used by the voice properties or speech authentications like nasal tone, fundamental frequency, inflection, cadence. The device produces speech patterns by combining the datas captured in the device.

  • Signature Recognition

    Signature recoginition can be operated in Static and Dynamic method. This technique is based on the phusical activities of signing like the amount of pressure applied, stroke and the speed etc.

  • Finger Vein Reader

    The security system which uses the Finger vein reader, it captures an image of the vein patterns which exist beneath the surface of the finger. Vascular pattern is detected using a near-infrared LED. It detects the hemoglobin in the bloodstream, providing a distinct pattern.

  • Multi-biometric Readers

    Multimodal readers deals with a number of different biometrics. For example, they can read both fingerprint and/or finger vein, or fingerprint plus facial recognition. It uses a combination of facial features and the way a person walks towards the camera. These systems operate very quickly and improve the accuracy. They are high capable devices for transmitting and receving the biometric inputs and data.
