For car owners who often drive in the United States, it is not uncommon for a police officer to be on the highway and to ask for a parking permit. Generally speaking, when the police car behind your car pulls the alarm and then asks you to stop by the loudspeaker, they will first search for your license plate information through the on-board computer before going out of the police car and approaching the vehicle from the rear. Drive on one side. If there is a suspect in the vehicle being inspected and carries a gun, the police will undoubtedly face a huge life threat.
In fact, such a malicious assault case occurred in the Long Island area near New York City earlier this year. At that time, a policeman in the Suffolk community was wounded by a suspect in a routine inspection on the road, and subsequent investigations revealed that the suspect happened to be a “known local gang memberâ€.
In this regard, Mario Savio, a professor of engineering at Carnegie Mellon University, said that he may have found a solution to this problem. Because he invented a remote iris scanning technique that allowed the police to quickly read the iris information as the owner's eyes inadvertently swept through the vehicle's rearview mirror. In other words, the emergence of this technology allows the police to know if there is a dangerous person in the target vehicle before stepping out of the police car.
Endless potential
Savio said that this is the world's first effective long-distance iris scanning technology. Simply put, the human eye is composed of three parts: the sclera, the iris, and the pupil. The sclera is the white part of the periphery of the eyeball, which accounts for about 30% of the total area; the center of the eye is the pupil part, accounting for about 5%; the iris is located between the sclera and the pupil, containing the most abundant texture information, occupying 65%, for individuals It is said to be as unique as a retina or a fingerprint.
Specifically, the iris morphology of the human body can remain unchanged for decades. On the other hand, the iris is visible externally, but at the same time belongs to the internal tissue, behind the cornea. If you want to change the appearance of the iris, you need a very fine surgery, and you run the risk of visual impairment. Therefore, the uniqueness, stability and unchangeable characteristics of the iris have long been used as a material basis for identity identification.
“Usually, fingerprinting technology requires the user's finger to touch the identification device. However, iris scanning can achieve this within a certain distance, so the overall user experience of this technology will be comfortable and natural. Unlike all scanning devices, this long-distance iris scanning technology does not require you to stand inside a machine for identification, nor does it require you to stand in a specific 'X' position, because you only need to be within 6-12 meters. This test device will successfully capture your iris information and the entire facial contour,†Savio said.
Carnegie Mellon University said that this technology can be applied to many practical fields besides being used in the police field. For example, people's iris information will completely replace government-issued ID cards and other documents, and make the landing system in traditional notebooks obsolete. Savio believes that the existing password protection mechanism has been completely outdated, and almost everyone hopes to minimize the possibility of the police being attacked during routine inspections on the road.
Raise concern
However, the emergence of this technology has also caused people to worry about the privacy and security issues that the government may have after abusing the technology. For example, the government can use this technology to scan the iris information of every pedestrian on the city street and clearly grasp the specific whereabouts of each person, whether he is driving, walking or passing the security check at the airport.
In this regard, Savio believes that there are still many things in the world that are worth worrying about. “I often hear people say this, 'Hey, now others can follow me through bioinformatics.' But in fact it is not because the cost of this approach is too high. And people can Through credit card transactions and various types of membership card information, the outside world is tracked by the outside world. If someone really wants to do this, they don’t have to rely on this novel facial recognition or iris recognition technology to do this because They have long been able to do this," Savio said.
At the same time, the US media has also pointed out that the practical application of this technology will make it more difficult for some innocent political activists to flee from the opposition regime.
"I am very pleased that some media have put forward this hypothesis. In fact, I have just discussed this topic with a non-profit organization. At present, a serious problem facing the world is the issue of human trafficking. There are many children being Kidnapping and selling abroad. If we establish a system in the country that can identify the trafficked population, I believe that many governments will be very interested in this, because this system will become a powerful weapon to effectively control human trafficking. In fact, human trafficking is common in every country, and if the technology I invented can help save more abducted children, I will be able to sleep more at night.†Savio added Road. In addition, Seraphim Global, a non-profit organization based in Virginia, which is committed to addressing human trafficking, said it has already engaged Savio with this aspect of cooperation.
Practical range
It should be said that iris scanning technology has been put into practical use in many countries around the world. For example, US police have used this technology to record criminal iris information for at least four years.
“Every prisoner in our prison is wearing an orange jumpsuit, so they all look very similar. So before the prisoner’s sentence is released, we need to compare its iris information with our database to ensure Nothing wrong.†A spokesperson for the county prison in Plymouth County, Massachusetts, said in an interview with Reuters in 2011.
Around the year 2011, the Indian government began collecting iris information for each citizen and awarded them a unique identification number. At the same time, the United Arab Emirates scanned iris information for all inbound and outbound people as early as 10 years ago.
In fact, iris scanning technology has been more supported in the United States because it is more obvious when deployed and used than other information recognition technologies. "This technology requires a certain degree of collaboration when used, so it will be very conspicuous, that is, people will know clearly that we are collecting their iris information," said an iris scanning technology CEO in an interview in 2011.
Savio said that if the technology succeeds in the future, his team will continue to research to make it cheaper and easier to use. "Hollywood's work has been smearing this technology all the time, but the purpose of my development is to improve social development and save lives." Savio finally said.
