With the security of the degree of improvement, as a branch of the security field, biometric technology will also usher in new needs and changes, biometrics and Internet of things, the Internet, the Internet, the Internet, Of the intersection will become the next focus of the security industry. Hollywood blockbusters, often through the scanning of the eyes open a confidential room or safe cool scene, it seems iris recognition is only used for highly confidential places. But in fact, with the advent of Internet of Things, the importance of data security is self-evident, iris recognition technology as the "21st century most promising biometric authentication technology", has been widely concerned, has been applied to finance, E-commerce and other fields.
Iris recognition without dead ends
Iris recognition technology is based on the human eye iris identification, is currently relatively high security biometric technology. Iris itself and iris recognition technology to ensure the safety of the technology is much higher than the face recognition and fingerprint recognition.
1, iris is highly unique
The human eye structure consists of sclera, iris, pupil lens, retina and other components. The iris is located in the black pupil and the white sclera, occupying 65% of the total area of the human eye. Contains the richest texture information. By many glands, wrinkles, pigmentation spots and other components, is one of the most unique structure of the human body. Its structure is thousands of times more complex than the fingerprint.
These characteristics determine the uniqueness of the iris, but also determines the uniqueness of the identity. Each iris is unique. Iris irreplaceability greatly protects the reliability of iris recognition.
2, iris has a very high stability and can not be changed
The formation of iris is determined by the genetic basis, the expression of the human body determines the iris morphology, physiology, color and total appearance. Iris in the fetal development stage to form, to eight months or so basically developed to a sufficient size, entered a relatively stable period. The iris morphology can remain unchanged for decades without exceptionally unusual abnormalities, physical or mental trauma that may cause changes in the iris appearance.
On the other hand, the iris is externally visible, but at the same time belongs to the internal organization, located behind the cornea. To change the appearance of the iris requires a very fine surgical operation, and to risk the damage of vision. So the iris as a "password" has a better "long-term security."
3, iris has a large number of quantitative feature points for the calculation
An iris has about 266 quantified feature points, while the general biometric technique has only 13 to 60 feature points. The iris recognition algorithm of 266 quantization feature points is described in many iris recognition technology. Under the condition that the algorithm and human eye features allow, the algorithm can obtain 173 independent degrees of independence of binary degrees. In biometric technology, the number of feature points is quite large. Thus in the security of a great guarantee.
4, iris recognition technology does not require physical contact
Fingerprint recognition on the finger cleanliness, dryness requirements are high, dirty, wet, oil and other factors will interfere with the machine identification. Fingerprint recognition verification, the fingers of India different angle, the intensity of different factors will affect the recognition results. Moreover, the fingerprint identification process, the fingerprint reader will leave the user's fingerprints, the user's fingerprints may be copied, the security greatly reduced.
Iris recognition does not need to contact with the machine, the identification process requires the eyes and the machine to maintain the distance of about 20-25cm, will not leave the biological residue, it is difficult to be copied, more reliable. In a particular scene to use more convenient. For example, in the hands of water or wear gloves to operate the phone, do not need physical contact iris recognition is clearly more convenient than fingerprint identification.
5, iris recognition technology is the use of living information
Iris recognition technology requires living iris information, when a person died, the pupil will naturally enlarge, resulting in iris disappear. Or the eye is stripped of the human body, the iris will lose the activity with the pupil magnification, will be rejected by the machine, therefore, iris recognition of the higher security. And because the iris is biotic, the image on the photo or video can not be recognized.
6, iris recognition of the false rate is very low
In the field of human biometrics, the recognition rate is a very important indicator, the lower the value, the more accurate the identification, the more likely to reduce the possibility of error. Iris recognition of the recognition rate of 1/1500000, compared with the fingerprint recognition error rate of 0.8%, face recognition was 2%. Some experts believe that in the biometric technology, iris recognition accuracy after DNA identification.
Q: Does the iris recognize the light and radiation that can cause harm to the human eye and body?
A: There is little damage to the eyes. Iris recognition is infrared, and is the general strength of the infrared, light intensity with natural light almost. Use 100,000 times less than 1 minute to play the phone.
Although the current iris recognition technology is still in development, but the performance of the security than the commonly used biometric technology is much higher. The technology in the world has been widely used in coal, banking, prisons, access control, social security, medical and other industries, in the consumer market, the application of the market also showed an upward trend. Research firm data show that iris recognition market share is expected to rise from 7% in 2015 to 16% in 2020, the average annual compound growth rate of more than 36%, of which the application of the mobile market size of 13 billion US dollars, the prospects are very broad.
