What is eye regeneration?<br />Retinal regeneration refers to the restoration of vision in vertebrates that have suffered retinal lesions or retinal degeneration.<br />What is the fingerprint in the beginning?<br />The fingerprint is in the language of the trail, so he left his fingerprint, that is, he left a trace that testifies to him. The fingerprint, as we used to it, is the effect of stamping with the finger, and it has been common since ancient times that no person is similar in his fingerprint with another human being, so the fingerprint was an important tool for revealing the mysteries. Fingerprint, but what is an eye print? Is it like the thumb is not the same from one person to another?<br />Eye Regeneration:<br />The eye print is the shape and color (pigments) of the layers that make up the eye (externally), the cornea, the iris, and the pupil, which is a group of holes of different shapes and sizes and the distance between each other, which are located around the pupil. In the eyes, and they are not really the same from one person to another, rather they are not similar even in identical twins, and they are the best in security, as high-quality imaging devices can capture the eye print even without you noticing, and the iris is the one that is examined, as it is the only visible part of the eye to the beholder, The iris is made up of involuntary muscles, and it is these muscles that make up the design of the iris.<br />Iris Finder:<br />The first to refer to the existence of the so-called iris fingerprint was the doctor (Frank Burch), then came (James Dugart) to explain it more clearly in his book in 1949, and the matter remained far from the application, until the scientist (John Dogman) wrote an algorithm that solves the problem of iris print, He did this in 1994 with the support of ophthalmologists Sapphire and Flom, and since 1997 this nascent technology began to be applied in the banks of many countries, and today it is applied in banks all over the world, and it is one of the best and safest technologies.<br />Change the shape of the eye print:<br />Does the eye print differ after a vision correction operation, for example? This question is self-evident, because vision correction operations target the cornea, which protects the iris, so does it change its shape? No, the shape of the iris remains fixed, there is no operation that can change it, and it is important to know that the shape of the eye print does not change with age, it remains almost constant after the age of two years, until the time of death, and most of us think - from the influence of thrillers - that it is possible Taking the eye of a dead person to open a safe or a secret door, but this is pure science fiction, it cannot be true, as we mentioned before that the eye regeneration It is made up of involuntary muscles, which relax and fade in shape upon death. If a person dies or his eyes are stolen, this technique fails to identify his person through an eye print. As for the name of the device capable of photographing an eye print, it is the slit lamp, which is the same device.<br />Used by ophthalmologists to examine the eye, and it is horrible to know that so far there are no<br />A technique to imitate an eye print.<br /> How does the fingerprint device work:<br />The fingerprint device provides unique protection to its user, unlike traditional methods of protection, such as using keys or even passwords, which can be lost. The fingerprint, regardless of its type, according to three main steps, and these steps are as follows:[1] Registration: by taking the basic information of users such as the name or identification number and taking pictures of the users.<br />Storage: where all information about a particular user is stored in the form of symbols or graphs, and some of these symbols may be placed on an identification card that the user carries.<br />Comparison: by matching the characteristics provided by the user to the fingerprint device with the data stored in it, and determining whether there is a match or not.<br />Types of fingerprint devices:<br /> There are several types of fingerprint devices, and the following are the different types of fingerprint devices:<br /> Facial fingerprint device: This type of device measures the distances between the components of the user's face, such as the distance between his eyes and his chin, for example, and some facial fingerprint devices are so advanced that they distinguish between the user's real face and an image taken of his face.<br />The fingerprint device: It is a device that works by scanning the user's fingerprints, and it is worth noting that the fingerprint device can be defrauded through some devious methods.<br /> Eye fingerprint device: This device identifies a person based on his iris, and the iris scan is the most secure type of fingerprint device.<br />Voice fingerprint device: People in this type of device are identified by their voice.<br />Features of using the fingerprint device:<br />The fingerprint device for the fingerprint is one of the types of fingerprint devices that is used to verify the identity of users, and the advantages of using this system are the following:<br /> Ease of action: where the user can unlock certain devices with just one finger. Difficulty of forgery and guesswork: It is very difficult to forge the fingerprint and thus the true identity of the users can be determined.<br />Getting rid of the problem of forgetting: The user of the fingerprint will not face the problem of forgetting his fingerprint, as it may happen sometimes from forgetting some passwords.
