We also have to consider the advantages and disadvantages of each individual system. From this comparative table we can deduce that the most adequate methodology is the fingerprint authentication. What are the pros and cons of iris recognition? Retina scanning occurs when a beam of infrared light is projected into somebody's eye via an eyepiece. Retinal scans map the unique patterns of a person's retina. It is considered that is even less falsifiable than the manual signature recognition (although this last is already enough trustworthy). The technology and innovation of . A lot of people assume that a retinal scan can pose a serious health risk to the eye (although unsubstantiated by scientific studies, it still persists). Hand Geometry: The best OCT machines on the market are provided by the brand Zeiss, which specializes in ophthalmologic devices. However, distinct differences exist which sets these two modalities apart that are suitable for specific use cases. Though it requires special hardware to use, it can be easily integrated into other devices or systems. Taking all of this into consideration, the market applications are extremely limited for Retinal Recognition. Passwordless authentication Why is it more secure? Your email address will not be published. Although there are some concerns, there are no long-term issues with the technology. Advantages: User-friendly; less expensive. In an eye scan of the retina, an unperceived beam of low-energy infrared light casts a beam into the eye as the patient looks through its eyepiece. Advantages and Disadvantages of the Iris for Identification. What are the goodness and weakness about the current technology? The advantage that Biometrics presents is that the information is unique for each individual and that it can identify the individual in spite of variations in the time (it does not matter if the first biometric sample was taken year ago).The pillars of e-learning security are: authentication, privacy (data confidentiality) authorization (access control), data integrity and non-repudiation. Iris recognition is used to secure airports, perform sensitive construction tasks, and operate in military operations. c. It is not valid for arthritic person, since they cannot put the hand on the scanner properly. Thus, the need for Penetration Testing across all levels is required to make sure that all of the hidden security vulnerabilities can be discovered and quickly patched up. Advantages and Disadvantages of Biometric Authentication. 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. (required). Advantages: Advantages: a. This technology is distinguished by its ability to match a user database with a series of scans, which is usually configured to identify a user by number of scans. 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. Since they are non-contact biometrics, both techniques are less vulnerable to identity theft than fingerprint, voice, etc. c. Comparisons of template records can take upwards of 10 seconds, depending on the size of the database. Iris pattern recognition tends to be more acceptable to users compared to retinal pattern recognition. Infosec, part of Cengage Group 2023 Infosec Institute, Inc. Advantages: Save my name, email, and website in this browser for the next time I comment. Should they be? Since then, the system has only seen immense improvements and aided business owners. 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. Thus, as a result, if the process is not done correctly, it can lead to a very large False Rejection Rate (this occurs when a legitimate individual is improperly denied access to either physical or logical based resources by the Retinal Recognition System). While the texture of a persons iris remains stable over time, the accuracy of retinal scan measurement can be affected by disease. This includes military installations and bases, nuclear facilities, and laboratories where very high calibre research and development is taking place. 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. a. Very expensive. Very high accuracy. The Retina scanner can not only determine who has access to a building, but it can also help employers monitor employee performance. A visual inspection of the retina is frequently used to diagnose communicable diseases such as HIV/AIDS and chicken pox. Although concerns exist that infrared rays could have a negative impact on vision, most experts believe that retinal and iris scanners pose no health riskto users. Copyright 2021 by JojoCms. This is because the scan area is so small, when compared to the other Biometric modalities. The biometric system allows them to limit access to unauthorized personnel. A 500 dpi fingerprint image at 8 bits per pixel demands a large memory space, 240 Kbytes approximately Compression required (a factor of 10 approximately). A 500 dpi fingerprint image at 8 bits per pixel demands a large memory space, 240 Kbytes approximately Compression required (a factor of 10 approximately). The speed of iris scanning and the visibility of the eye, alongside the incredibly low rate of false matches, are some of the main reasons why this biometric technology is gaining traction. Besides, sometimes they are combined with cryptography methods, which makes them more difficult (more expensive) to implement. Advantages: The user has to keep his/her eyes steady, especially in case of retinal scan. In retina scanner technology, blood vessels are mapped in a persons retina and this pattern is used to confirm identity. Thus, it is also deemed to be the smallest Biometric Template of all. Fundus autofluorescence utilizes the natural fluorescent properties of lipofuscin within the retinal pigment epithelium to create an image of the retina. It is more prone to spoof attacks than retina recognition. Since the retina is an internal protected organ, it requires specialized ophthalmologic cameras for retinal image acquisition, making it impossible to spoof the retina to date. Scanning procedure is perceived by some as invasive. Because Retinal Recognition requires such a close proximity to the end user, there are a number of variables or factors which can greatly influence the quality of the raw images which are collected. Throughout the entire human anatomy, it is the eye which captures the intrigue of both medical practitioners and research scientists. Retinal recognition - The ultimate biometric | Infosec Resources Disadvantages: Unlike the iris, the retina can be subjected to changes if an individual is afflicted with a disease or blindness. a. The retina is the innermost layer of a . 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. The iPhone 11 is Apples most recent smartphone, and it includes a number of exciting new features. Retinal scanning and iris recognition are two of the most accurate and reliable biometric modalities used for identity verification and authentication. Subject being scanned must be close to the camera optics. DNA: Second, this small size means that a greater number of templates can be stored in a single database, and optimizing it will be much more efficient when compared to a database of Facial Recognition Templates, where the sizes are much larger. Permanence. How the retinal scan works; Applications; Advantages and disadvantages; A new device called an iris scanner might be more beneficial for these everyday transactions since the scanning camera may be farther away and only has to scan the iris pattern (color portion) of the eye. c. Cheap technology. Measurement accuracy can be affected by a disease such as cataracts. This site uses cookies to provide services, personalise ads and to analyse traffic. The physical authentication gives HR officers and organizations control over who has access to the office building, vaults, sensitive data, and lockers. The advantage that Biometrics presents is that the information is unique for each individual and that it can identify the individual in spite of variations in the time (it does not matter if the first biometric sample was taken year ago).The pillars of e-learning security are: authentication, privacy (data confidentiality) authorization (access control), data integrity and non-repudiation. Once identity is verified through a retinal scan, there is almost no error given the high number of unique data points of the retina. The biometric system offers users the flexibility of using physical traits and eliminating the need for remembering passwords or pins. To date, different biometrics have been researched and used, such as fingerprint, hand geometry, face, odor, DNA voice, ear, gait, etc. The technology can be used for more than one aspect of the organization, whether its a new department or a special project. a. Retinal recognition: pros and cons - Keesing Platform As a result, the Ability to Verify metric can be as low as 85% (other modalities are as high as 99% or even 100%). The Smart Cards are very useful since they can be easily combined with other authentication systems, serving as storage system. Biometric is a technique that can provide all this requirements with quite lot reliability. Employees can just use the retina or fingerprint scanner to sign in to record their attendance. This technique is currently used in two distinct forms: imaging of the retina and imaging of the blood vessels. Advantages: This imaging method uses a dim red light to reflect off the retina and optic nerves. The interest of using the Retina as means for verification and/or identification goes back all the way to the 1930s. Both techniques use near-infrared light to illuminate the object (iris or retina) of interest. In the end, Retinal scans can assist businesses in determining whether employees are who they say they are and in ensuring that they do. Advantages: Ease of use. The device is much better than a resource who would do the same job for a hefty salary. Since iris patterns stay practically unchanged throughout a persons lifetime, iris recognition is one of the most accurate biometric modalities that are commonly deployed. Can your personality indicate how youll react to a cyberthreat? The first study to confirm the uniqueness of the retinas blood vessel pattern was released in 1935 by Dr. Carleton Simon and Dr. Isodore Goldstein. Ravi Das is a Cybersecurity Consultant and Business Development Specialist. Although biometrics is considered the most effective and safe method (is very difficult to falsify), we have to bear in mind its disadvantages, for example, that since it is a relative new technology, it is not still integrated in PC, so IT departments need to make a conscious decision before making the purchase and change its structure. One of the Biometric Templates which is used quite heavily in the e-Passport infrastructure is that of Iris Recognition. Once the data is stolen, no one can do anything about it because it cant be altered. Any sudden or unintentional movement can negatively affect the lens alignment of the aperture which is used to transmit the infrared light beam into the Retina. What Is an Optomap Eye Exam? - All About Vision The password method is the cheapest and simplest technology, because it only requires elementary software resources. This is because the scan area is so small, when compared to the other biometric modalities. In contrast, the e-Passport is a much secure identity document. c. it is one of the most developed biometrics Top 8 Advantages and Disadvantages of Biometric Not very user friendly. 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 just less than two seconds. It is a physiological feature of the retina that remains constant throughout a persons life. Terms of use / Privacy policy / GDPR, About this workspace Because of this improvement in resolution, it is now more feasible to image the back of the eye using an OCT. retina scans are becoming more popular in terms of their ability to access restricted areas and information, with many experts concuring that they pose no health risks or other drawbacks to users. Over 20 years ago, a company known as Optos introduced optomap ultra-widefield retinal imaging. Biometrics - Retina and Iris Identification - GlobalSecurity.org Close proximity to an eye scanner is also required in retinal scanning (much like looking into a microscope), whereas iris recognition, being a normal photo capture process, can be taken even from afar. This is in sharp contrast to Iris Recognition, where images can be collected from a very far distance. 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. 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. It impossible that the system made mistakes. Retinal vs. Iris Recognition: Your Eyes Can Get You Identified? Fundus photography - Wikipedia As it was discussed, the e-Passport is quickly becoming the replacement for the traditional paper passport. They can be described as follows: 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: Each and every individual, unless they are afflicted with blindness or some other serious disease of the eye, has a Retina, so thus, it can be scanned. Biometric is a technique that can provide all this requirements with quite lot reliability. The Smart Cards are very useful since they can be easily combined with other authentication systems, serving as storage system. Biometric authentication comes in play to release the users from the difficulties of remembering and protecting passwords. Advantages: a. Intrusive. Simply put, it is virtually impossible to be falsely accepted by a retinal recognition system. Because injuries are not always obvious in imaging or in retina examination, there is the possibility that injuries can be avoided or that injuries are more likely to have a significant visual impact than other types of injuries. As mentioned earlier, the acceptance of retinal recognition by the general public is extremely low. Cheap technology. Advantages: The more complex is the system, the most difficult is to be attacked, although it will be more expensive and will require more software and hardware resources. Free Valentines Day cybersecurity cards: Keep your love secure! Most smartphones, in the present day, have fingerprint scanners that allow the user quick access to the files on their phones. Retinal Scanning Definition, FAQs - Innovatrics The biometric system only allows access to authorized personnel and keeps out intruders. c. It is not valid for arthritic person, since they cannot put the hand on the scanner properly. Learn how your comment data is processed. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. Each iris is unique, and even irises of identical twins are different. Like any other system, the biometric system is not perfect. On the other hand, iris recognition is considered more user friendly as it uses contactless digital photography to precisely verify identity. All rights reserved. Since retinal recognition templates are incredibly small, it is quite fast to confirm the identity of a person. a. Made up of multiple layers of neurons, the neural retina is adjoined by a series of synapses, wherein an outer layer of pigmented epithelial cells support it. a. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. Measurement accuracy can also be affected by severe astigmatism. The first retina scanner was developed in the late 1970s by American ophthalmologist, Dr. Joseph J. Atick. Because of the high number of unique data points the Retina possesses, there is almost no error that when an identity of an individual is confirmed, it is truly that person. Iris Recognition and Retina Scanning are the physiological biometrics methods for identifying a person or verifying a persons identity. Several experts have stated that retina scanners pose no health risks or other issues to users. They can range from very simple applications, such as Single Sign-On Solutions, all the way to the most complex, such as that of the e-Passport infrastructure. We also have to consider the advantages and disadvantages of each individual system. The false acceptance rate and false rejection rate of iris scanning is extremely low, guaranteeing a higher rate of accuracy in identity verification and authentication. Each persons retina scan is distinguished by a few distinct characteristics. Retinal Physician - Retinal Imaging Modalities: Advantages and If the data were stolen, they cant try to change their identification traits like they can change passwords during a security breach. To initiate a reliable iris recognition process, a proper setup is a must. Because of its stability and richness, it is almost impossible to spoof a Retinal Recognition system. Limitations: Lower resolution (10 m); poor resolution of retinal layers; slower image capture; no eye tracking feature. Retinal imaging can alert both patients and providers to health issues like Age-related Macular Degeneration, Cancer, Diabetic Retinopathy, Glaucoma, Hypertension (High Blood Pressure), Retinal Detachment, and more. 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. Required fields are marked *. Important Note : The use of eye drops isn't normally needed in high-resolution retinal imaging, but it may be needed in special cases such as eye exams before Lasik surgery. The analysis of an idea, as it used to be carried out, was, in fact, nothing else than ridding it of the form in which it had become familiar.Georg Wilhelm Friedrich Hegel (17701831), Extremely low (almost 0%) false negative rates, Highly reliable because no two people have the same retinal pattern, Speedy results: Identity of the subject is verified very quickly, Measurement accuracy can be affected by a disease such as cataracts, Measurement accuracy can also be affected by severe astigmatism, Scanning procedure is perceived by some as invasive, Subject being scanned must be close to the camera optics. The second type of imaging is based on advanced equipment capable of image 220 degrees of the retina. Signature verification is designed to verify subjects based on the traits of their unique signature. . Even if the individual is fully cooperative, it can still be difficult to a collect a high-quality, raw image of the retina.
