They appreciated the automation and development of modern technological systems, such as mobile phones and Internet users who have the prevalent use of technical capabilities, but is run by people for the acquisition of authentication. Personal identity has developed the capacity of a PIN and password private. Passwords are regularly on things like mobile phones, ATM use, personal computers or Internet access. But there is a problem with the system’s use of passwords for security reasons.
To produce the password is not accessible to other people, must be unique, not in the dictionary and must contain symbols like%, #, or @. In addition to active safety, has a password in order not to be written, not access to other people, and must be changed at least once every three months. The men of today, as a large number of passwords and is not annoying to the memory of this. While welcoming the password as a machine, they are as user friendly for others.
There is an answer that you look at the possibilities of nature. For the identification of a person, people with physical features such as face-up or voice contradistinguish. Biometrics, the science of detection and measurement of contrasting physical, now recognizes many features perfect for the clear recognition of an identical twin is also affected. Examples include the iris, fingerprints, and the structure of the veins. Planned to fulfill the task of recognition based on the human brain (the brain only uses a biometric identifier individualist), 100 million calculations per second are necessary. More recently have standard PCs reached this speed, and it is also clear that the sensors needed to evaluate the properties are always more accessible. Therefore, the time needed to complete the password came with consumer-friendly solution – biometric authentication.
There are several ways in which the biometric checks are done. Some of them are listed below.
Finger Identifications
Ridges of fingerprints in the uterus only after four months, the development of the fetus size. These fingerprints are so trained to present the images on a surface of a balloon. Preserving the fingers of a person, tall, with age, but the relationship between the ridges of fingerprints is constant. For this reason, the identification of fingerprints as trusted.
The palm vein authentication
The palm vein authentication is a system that uses infrared rays are penetrating into the hands of users, while she waved for authentication. The palm vein obtained as black lines returned. The complex nature of the vein pattern makes this system correctly. Since the veins in the body of a person is, this system is difficult to forge.
Retina scans
The method of scanning the retina contains an analysis of the blood vessels in the eye are present. This pattern does not change throughout the lifespan. A light of low intensity are used to capture images of the model of blood vessels. It ‘a very reliable method of identification used by the biometric data.
Iris scans
The iris scan is a method of scanning of freckles, rings and furrows in the ring, are pupils of the fence eyes. The method involves the use of almost 200 points for the comparison and is very reliable.
