Little time of verification (about five seconds). There are pros and cons to both options. What are the goodness and weakness about the current technology? The first scientific study was conducted by Dr. Carleton Simon and Dr. Isodore Goldstein. This layer on the back of the eye has complex blood vessels and nerve cells, creating a pattern beneath the surface that is unique to each individual. How safe is an etinal scan? Your email address will not be published. Highly protected, internal organ of the eye. Since every iris is unique to an individual, iris recognition makes for an ideal form of biometric verification. To initiate a reliable iris recognition process, a proper setup is a must. In retina scanning (a type of eye scanning similar to the way a microscope is used), the eye scanner must be close to the patient, whereas in iris recognition, a normal photo-capture process, the eye scanner can be taken from afar as well. The process involves the acquisition and processing of images, unique feature extraction, and template creation and matching. In a variety of high-risk sectors, such as border patrol and aviation, retina security scanning has demonstrated its ability to implement reliable biometric security protocols. Because of the attention that is required by the end-user, it can take. Making Secure Electronic Documents Cyber Resilient: Part 2, Physical & Behavioral Biometric Technologies: Part 11, Making Secure Electronic Documents Cyber Resilient: Part 1, Physical & Behavioral Biometric Technologies: Part 10, Digital Travel Credential Between Canada and the Netherlands, The retina is deemed to be very stable, and hardly ever changes over the lifetime of an individual. And used like the only identification system, is not excessively trustworthy, since it can be easily stolen, lost or simply forgotten at home. b. While rods generally function in dim lighting conditions and are responsible for black-and-white vision, cones are built for brighter lighting conditions and are in charge of recognizing colour. One of the Biometric Templates which is used quite heavily in the e-Passport infrastructure is that of Iris Recognition. Stolen company credentials used within hours, study says, Dont use CAPTCHA? The ability of CT scans to produce detailed images of the inside of the body is astounding. Physical access and access control devices are the most commonly used types of retina scan devices, and they are typically used in environments requiring exceptional levels of security and accountability, such as high-level government, military, and corrections settings. Consequently, retinal scanning devices are costly. Iris pattern recognition tends to be more acceptable to users compared to retinal pattern recognition. There is a very strong unease about having to place the eye into a receptacle and having an infrared light beam being shone directly onto it. Light from a small fiber-optic device, such as a fiber-OCT, is used to illuminate the retina. It is a great way to monitor your eye health over time and check for any health problems that may arise. At this stage, up to five raw images can be collected and analyzed, in order to create the composite image from which the unique features will be extracted. What is the difference between retinal scanning and iris recognition? Learn how your comment data is processed. Each one of the Technologies used in our days bring us a manner to restrict the access to a system, allowing the entrance only to those persons who know a specific code, own a card or have determined physic marks. b. Retina scanners are devices that capture images of the unique patterns on a persons retina, which is the innermost layer of the eye. This is, of course, has numerous advantages to it. It is the most scalable security solution for big and small businesses today. Difficult to integrate with other systems. As it has been described, the individual must remain perfectly still throughout the above-described process, especially when the raw images are being captured. Light passes through the optic nerve and sends electrical impulses to the brain via this layer. With retina scanning, it is possible to see the unique patterns of a persons retina to ensure that only the appropriate individual can access restricted areas or information. Patterns in the iris and retina are unique not only for each individual, remains intact throughout life under normal health condition. In other words, the retina fundamentally acts as the image sensor in a camera. Retinal Vue - Retinal Scan: Retinal scanning is one of the most well-known bio metric technologies. c. it is one of the most developed biometrics, e. Small storage space required for the biometric template, reducing the size of the database memory required. Advantages: Ease of use. You have successfully joined our subscriber list. Copyright 2021 by JojoCms. The retina scanner is a type of biometric scanner that uses the unique patterns in a persons retina to identify them. The retina is the innermost layer of a human eye. Regarding the former, the paper passport can be, to a certain degree, easily forged, replicated, or even hijacked. . Signature verification is designed to verify subjects based on the traits of their unique signature. Digging the government database or awaiting response of a government agency for identity verification can be painfully slow process. Overall, the effectiveness and viability of retinal recognition can be examined against seven criteria which are also used by the biometrics industry here in the United States: Universality: document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. Permanence: Thus, it is also deemed to be the smallest Biometric Template of all. Retina scanner scans the blood vessel patterns at the back of the eye and is a very reliable and foolproof system. Very high accuracy. This same process is also used to create the Verification Template. Unlike the other Biometric modalities, Retinal Recognition requires a great amount of cooperation from the end user to collect high quality, raw images. Although an infrared light is beamed directly into the eye, there is no scientific study that supports the assumption that the retinal scan damages the vision of the user. Moreover, they also require a person to stay still and avoid extra movements. Furthermore, they can be used to diagnose and treat a wide range of medical conditions, are safe, and are relatively painless. Nowadays, retinal scanning has also been deployed in a number of applications, including ATM identity verification and prevention of welfare fraud. Most smartphones, in the present day, have fingerprint scanners that allow the user quick access to the files on their phones. a. Intrusive. If you are not a robot then please try again. In terms of commercial adoption, iris recognition has surpassed that of recognition. CT scan machines are now widely used in hospitals and clinics all over the world. What are the goodness and weakness about the current technology? The second study by Dr. Paul Tower came out in the 1950s. Recent technological advancements have made the process much more pleasant. The retina is the innermost layer of a . In the next paragraphs, we will make an enumeration of the problems that these techniques can present: a. Resolution: 8 bits per pixel. c. Image captured at 500 dots per inch (dpi). It was produced by EyeDentify, a company formed in 1976, still the primary manufacturer of these devices. Stay up to date with the latest news, offers and special announcements. Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. Please leave this field empty. In this regard, when compared to the other Biometric modalities, precision is of utmost importance in Retinal Recognition. Hand Geometry: In the next paragraphs, we will make an enumeration of the problems that these techniques can present: The device is much better than a resource who would do the same job for a hefty salary. Because of these strategic advantages, Retinal Recognition has been termed as the Ultimate Biometric of All. Retinal scans map the unique patterns of a person's retina. b. c. The amount of data required to uniquely identify a user in a system is the smallest by far, allowing it to be used with SmartCards easily. Enrollment and Verification Template Creation: Lack of cooperation on part of the individual: The distance between the individuals eye and the lens is too far: The Retina is deemed to be very stable, and hardly ever changes over the lifetime an individual. As a result, security teams can use it to combat fraud. From this comparative table we can deduce that the most adequate methodology is the fingerprint authentication. Non intrusive. Can your personality indicate how youll react to a cyberthreat? There is the possibility that infrared rays could cause damage to the retina. a. Self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. Retinal scanning and iris recognition are two of the most accurate and reliable biometric modalities used for identity verification and authentication. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. The password method is the cheapest and simplest technology, because it only requires elementary software resources. c. Very expensive Except for the DNA strand, it is the retina which possesses the greatest number of differing data points in the entire human anatomy. In contrast, retinal pattern recognition obtains the internal part of the eye, i.e., the retinas vascular pattern. These devices are primarily used in physical access applications, and they are used in environments with extremely high levels of security and accountability. In other words, the retina is to the eye as film is to a camera. Low accuracy. All rights reserved. As it was discussed, the e-Passport is quickly becoming the replacement for the traditional paper passport. Each one has advantages and disadvantages, including range, accuracy, costs . b. Verification time is about five seconds. The very high accuracy, attained in iris recognition today, suggests it to be a very promising biometric for authentication purposes. b. For example, it can be easily installed in the computer, a program that simulates the user name and password window, so that when the user introduces his data in that window, that will be collected by the Spy program. He also possesses the Certified in Cybersecurity (CC) cert from the ISC2. Advantages of the Iris for Identification. Because of its stability, the Retina possesses extremely high levels of accuracy. No votes so far! Taking all of this into consideration, the market applications are extremely limited for retinal recognition. Retinal scanning is a technology used to identify individuals by their unique patterns of blood vessels in the retina, located in the back of the eye. Hacking is an undying cyber theft, which means that hackers can easily manipulate stolen biometric data to create fake positives. As a result, the ability to verify metric can be as low as 85% (other modalities are as high as 99% or even 100%). Ravis primary area of expertise is Biometrics. Most experts believe that infrared rays, both infrared and non-radial, pose no health risks to users of retinovia and intraocular lenses. Data security is guaranteed once a physical trait is logged onto the system by restricting outside access. It is a very accurate form of identification, but it is also very expensive. and biometric where users can sign using the fingerprint on their smartphones! Iris patterns are more robust than voices. The Digital Signature is very difficult to falsify, since is encrypted by complicated mathematic operations. Live capture is the act or method of gathering biometric data from an individual while the individual is physically present. Disadvantages: b. Verification time is generally less than 5 seconds. The technology, however, has notable disadvantages including difficult image acquisition and limited user applications. The biometric system is also unreliable because its an automatic system that depends on electricity to run. In the end, Retinal scans can assist businesses in determining whether employees are who they say they are and in ensuring that they do. As mentioned earlier, the acceptance of retinal recognition by the general public is extremely low. Traditionally, businesses used to opt for the 'pen and paper' method, where an employee would sign in by penning his signature on an 'attendance sheet.'. If the data were stolen, they cant try to change their identification traits like they can change passwords during a security breach. Greenbone Security Manager (GSM) appliances, which are based on OpenVAS, are available from a number of resellers for prices ranging from $3,400 to $135,000. While the accuracy of retina scan can be affected by diseases; the iris texture remains extremely stable because it is internal and protected, yet externally visible part of the eye. It is a physiological feature of the retina that remains constant throughout a persons life. Advantages: a. Several high-risk sectors, such as border patrol and aviation, have chosen to use retina scans for their reliable biometric security protocols. It has no public attitude problems as it is associated most commonly with authorized access. This blood vessel pattern is a reliable biometric characteristic for retinal scanners. The biometric system can lead to the security of enterprises because it is a breakthrough that is improving with the latest technology to become perfect. Fortunately, advanced technology now offers a way to perform the retinal exam without the drop and dilation all through something called an optomap retinal exam. The primary reasons for this are for both security and convenience. Very high accuracy. Because of this, a travelers identity can be instantaneously confirmed in just a matter of seconds, by merely flashing the e-Passport in front of the e-Passport reader. c. It is standardized. Advantages and Disadvantages of Biometric Authentication. Thus, in this regard, it is considered to be the, Given the small file size of the retinal recognition templates, the time it takes for the system to confirm the identity of an individual is very quick; it can take place in, Since the retina is located from within the structure of the eye itself, it is not prone to the harshness of the external environment like, There is a very strong unease about having to place the eye into a receptacle and having an. A persons iris patterns can be used to generate digital templates that can be used for comparison and matching. For example, it can be easily installed in the computer, a program that simulates the user name and password window, so that when the user introduces his data in that window, that will be collected by the Spy program. Be the first to rate this post. Acquiring an image requires proper alignment and positioning. The biometric system has many forms, and the most commonly used are fingerprint scanner, face recognition, and retina scanners. As a result, it has also received great interest as well from the Biometrics Industry as a means to positively confirm the identity of an individual. Though it requires special hardware to use, it can be easily integrated into other devices or systems. A Retinas Scan has a 70 times higher accuracy than an Iris Scan, and a fingerprint Scan has a 20 times higher accuracy than a retina Scan. For reliable identity verification, digital templates based on the patterns of the irises of a persons eyes can be used for comparison and matching. As a matter of fact, the false rejection and false acceptance rate of iris recognition is significantly lower than that of fingerprints. Click on 'Write for us' to contact us. With an estimated error rate of just one in ten million, retina recognition technology has been implemented by several US government agencies such as the Central Intelligence Agency (CIA), and National Aeronautics and Space Administration (NASA). They are pattern-dependent, not sight-dependent. We use cookies to give you the best experience on our site. Retina scanning is different from iris scanning, as this biometric technology used an image of your retinal blood vessel pattern as an identifying trait. Genetic factors actually do not dictate the composition of the blood vessel pattern which make up the Retina. Despite these shortcomings, retina scan is a highly secure method of identification and immune to spoof attacks. Among the factors to consider is vulnerability scanners accuracy rate, as well as its reliability and scalability. The scan is painless, so you dont have to be concerned about being bothered. a. Both techniques use near-infrared light to illuminate the object (iris or retina) of interest. Infosec, part of Cengage Group 2023 Infosec Institute, Inc. The biometric system only allows access to authorized personnel and keeps out intruders. The fiber-optical coherence tomography procedure improves resolution by using a small fiber-optic light to illuminate the retina. It impossible that the system made mistakes. Despite the fact that standard ophthalmoscopy, fluorescein angiography, and fundus photography have not been documented as having resulted in serious injuries, these procedures are not uncommon. As a feature, their main competitor is the password (or PIN code, on occasion), so a comparison between the two will reveal both their flaws and weaknesses. Weigh the following factors as you consider implementing biometric technology into your business: Pros Cons; Because of this, up to 400 unique data points can be captured from the Retina, unlike the fingerprint, where only 30-40 unique data points can be captured. How safe are eye (retina and iris) scanning technologies? The following table compares some of the biometric systems used lately, from the point of view of accuracy, cost, devices required and social acceptability. So, this method, in spite of being usually used, for example, to access banking accounts, is not at all the most indicated if we want a safe system, and in a short-time future is tried to be changed by most immune methods. The iris regulates the amount of light that enters the eye by opening and closing the pupil, which is necessary for proper line of sight. The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula. We also have to consider the advantages and disadvantages of each individual system.
