What is the biometric system?
Biometrics is a technology that is used to identify a particular human being. Used primarily to ensure security for personal or business assets. The biometric system must first store the person's biometric data. After someone attempts to access the personal or business system, the stored biometric data is compared to the person who is currently approaching the system. If the data coincides, the person may have access to protected information.
The strong biometric system alleviates the weaknesses found in most protective systems. For example, most people using a password protected system create weak passwords. Passwords can often be guessed, which can allow thieves access to sensitive information or financial assets. It also removes problems associated with lost key cards and shared passwords. Biometry is specific to the person itself and cannot be stolen, guessed, lost or shared with another person.
Biometric system cane be physicaliiological or behavioral. If it is physiological, it measures a particular area of the human body. For example, one of the most basic and oldest ways to identify a person is through fingerprints. The fingerprints are somewhat cheap and can be added to computers, door locks, external hard drives and credit cards.
other physiological biometrics include scanning of the human hand, scanning of iris and scanning of face recognition. Although the scanning of the hands does not collect data from the fingerprints, it measures the angles of the fingers, the alignment of 27 bones in the hand, the pattern of hand veins and the location of other tissues, muscles and tendons in hand. Iris scanning measures a set of muscles that control pupils' dilation. Scanning of the face recognition measures facial features such as the distance between the eyes and ears aa the shape of the nose and mouth.
Behavioral Biometric System examines how specific person performs in particularthe activity. Among the most common systems using biometry of behavior are data collected from the manuscript of a person, the way they write on the keyboard, the sound of their voice and their walking. The data collected from the manuscript sample is considered by the image itself, the movement of the pen and the pressure of the pen. Looking at the keys, the rhythm, muscle tone and timing are considered. Sound and formula are considered when information about voice and walking for the biometric system is collected.
A good biometric system will consider only the unique and permanent characteristics of the person. The "lasting" characteristics will change very slowly, if at all, over time. For example, an adult's hand should look essentially the same for five years, which should balance an exceptional occurrence, such as an accident or surgery. Biometrics is more accurate and reliable than normal identification, making it one of the best ways to protect important information and assets.
