The fiber-optical coherence tomography procedure improves resolution by using a small fiber-optic light to illuminate the retina. What are the goodness and weakness about the current technology? Digging the government database or awaiting response of a government agency for identity verification can be painfully slow process. It seems that retinal recognition will only occupy a very limited pool of applications. Fingerprint: In fact, under optimal conditions, the error rate can be as low as 1 in 1 million. 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. However, there is a negative public perception regarding retinal scanning due to its intrusive nature. 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. Is the most economical biometric PC user authentication technique. For example, banks are investing in affordable mobile app development and biometric where users can sign using the fingerprint on their smartphones! Retinal scanning technology is mostly deployed in military installations and bases, nuclear facilities, and high-caliber laboratories. Little time of verification (about five seconds). 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. 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. The Smart Cards are very useful since they can be easily combined with other authentication systems, serving as storage system. c. It is not valid for arthritic person, since they cannot put the hand on the scanner properly. Has lower error rate (1 in 10,000,000) as opposed to fingerprint identification (1 in 500), Low false rejection rate and low false acceptance rate, Inconvenient for people who wear eyeglasses. Because of these strategic advantages, Retinal Recognition has been termed as the Ultimate Biometric of All. In contrast, retinal pattern recognition obtains the internal part of the eye, i.e., the retinas vascular pattern. What are the pros and cons of retinal scanning? b. Verification time is generally less than 5 seconds. On the other hand, iris recognition is considered more user friendly as it uses contactless digital photography to precisely verify identity. The iPhone 11 is Apples most recent smartphone, and it includes a number of exciting new features. However, iris recognition is widely accepted as a commercially-viable modality compared to retinal scanning. In the end, Retinal scans can assist businesses in determining whether employees are who they say they are and in ensuring that they do. It can make mistakes with the dryness or dirty of the fingers skin, as well as with the age (is not appropriate with children, because the size of their fingerprint changes quickly). c. Cheap technology. Retinal Scanning definition. You don't have permission to comment on this page. The Pros And Cons Of A Retina Scanner: Commercial Vs Open Source. The Retina CS software allows organizations to perform context-aware vulnerability assessments. Overall, it is expected that the use of Iris Recognition will grow rapidly over a short period of time, but Retinal Recognition will still only occupy that very limited of pool of applications just described, and not grow any further from that point. Both retinal and iris scanning are ocular-based biometric technologies. There is the possibility that infrared rays could cause damage to the retina. It has no public attitude problems as it is associated most commonly with authorized access. Thats because the system is reliable and enhances enterprise security. Fundus photography involves photographing the rear of an eye, also known as the fundus. 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. Retina scanning is different from iris scanning, as this biometric technology used an image of your retinal blood vessel pattern as an identifying trait. Copyright 2021 by JojoCms. This, in turn, can also have a huge impact on the quality of the Enrollment and Verification Templates as well. The biometric authentication system has an unmatched ROI as compared to other security solutions. It is a great way to monitor your eye health over time and check for any health problems that may arise. Several experts have stated that retina scanners pose no health risks or other issues to users. Several high-risk sectors, such as border patrol and aviation, have chosen to use retina scans for their reliable biometric security protocols. They are pattern-dependent, not sight-dependent. Even blind people can enroll successfully. One study on biometric authentication discovered that the false rejection rate of retinal scanning technology stands at 1.8%. b. Iris recognition is used to secure airports, perform sensitive construction tasks, and operate in military operations. retina blood vessels are examined during a delicate retina scan that remains unchanged from birth until death. Except for the DNA Strand, it is the Retina which possesses the most number of differing data points in the entire human anatomy. 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. . Based upon the unique physiological characteristics of the eye for identity verification, both retinal scan and iris recognition offer their own list of advantages and disadvantages. Learn how your comment data is processed. Even if the individual is fully cooperative, it can still be difficult to a collect a high quality, raw image of the Retina. with each device offering a unique set of advantages and disadvantages based on the imaging type utilized (e.g. 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. For a high-quality scan to take place, there must be a distance of not greater than 3 inches between the receptacle and the Retina. Your Email (required) You consent to our cookies if you continue to use our website. c. Cheap technology. If a condition or disease is found, the doctor will repeat the test with a . 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.'. 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). This is in sharp contrast to Iris Recognition, where images can be collected from a very far distance. Once identity is verified through a retinal scan, there is almost no error given the high number of unique data points of the retina. Even if a retinal scan itself poses no danger to the eye, users sometimes complain of discomfort from the technology during the enrollment process. On the other hand, iris scans capture a grayscale photo of a persons iris and are generally considered non-intrusive and more comfortable to complete. Iris recognition can be deployed in a wide variety of applications such as airport security, sensitive construction tasks, and military operations. Given the complexity of retinal biometrics, it is hardly surprising that retinal scanning technology only enjoys a low commercial acceptance. More info. Advantages: It is the former which allows for both night and peripheral vision to take place. https://platform.keesingtechnologies.com/author/ravi/, Part 1: Seeing eye to eye on iris recognition, Part 2: Seeing eye to eye on iris recognition. Taking all of this into consideration, the market applications are extremely limited for Retinal Recognition. But iris spoof attacks are possible even with a high-quality photograph. Furthermore, they can be used to diagnose and treat a wide range of medical conditions, are safe, and are relatively painless. He discovered that even among identical twins, the blood vessel patterns of the retina are unique. Now you can find what you're looking for wherever it lives. b. The technology can be used for more than one aspect of the organization, whether its a new department or a special project. The accuracy of retinal scanning varies depending on the quality of the image of the retina and the expertise of the person interpreting the scan. Because of the attention that is required by the end-user, it can take. High social acceptability. He is also a regular columnist for the Journal of Documents and Identity, a leading security publication based out of Amsterdam. Very high accuracy. Non intrusive. 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. Ravi Das is a Cybersecurity Consultant and Business Development Specialist. 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. Iris image capturing uses a video camera, while retinal scanning devices require specialized cameras used in ophthalmology. The technology and innovation of . 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. Except for the DNA strand, it is the retina which possesses the greatest number of differing data points in the entire human anatomy. Cheap technology. Our passion for technology brings biometric benefits to millions of people. Both iris and retinal pattern recognition are eye-based biometrics. Through a delicate sensor, a retinal scan examines the pattern of retina blood vessels, which remains unchanged from birth until death. 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). There is no scientific evidence to suggest that retinal scanning is harmful. COMPARISON of the advantages and disadvantages of biometric technologies. a. Your eyes are not at risk as a result of the scan, and your overall health is not threatened. They laid out their discovery that every retina possesses a unique blood vessel pattern. Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. . Advantages of the Iris for Identification. Limitations: Lower resolution (10 m); poor resolution of retinal layers; slower image capture; no eye tracking feature. c. The eye from a dead person would deteriorate too fast to be useful, so no extra precautions have to been taken with retinal scans to be sure the user is a living human being. It has the stigma of consumer's thinking it is potentially harmful to the eye. Installing and configuring CentOS 8 on Virtualbox [updated 2021]. Also like the Iris, the Retina hardly every changes over the lifetime of an individual unless they are afflicted with a disease or blindness. Retinal Scan vs Iris Recognition: Which is better? Regarding the former, the paper passport can be, to a certain degree, easily forged, replicated, or even hijacked. Over 20 years ago, a company known as Optos introduced optomap ultra-widefield retinal imaging. With the latter, processing a paper passport can take time, especially at the customs and immigrations line at the country of destination. Because their accuracy level of 0.0001% FAR makes them a powerful fraud prevention tool, security teams can rely on them to detect fraud. In fact, their published scientific paper, which came out in 1935, is considered to the be the formal birth of Retinal Recognition. Contact the owner / RSS feed / This workspace is public, Drive, Dropbox, OneDrive, Gmail, Slack, and browsed web pages. The iris is the pigmented, annular muscular curtain near the front of the eye, which controls the size and diameter of the pupil. There have been no documented cases in this regard. a. In a variety of high-risk sectors, it is extremely useful to use retina scanners to implement strong biometric security protocols. This beam of light traces a standardized path on the retina. 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. Two distinct layers make up the iris: the stroma, which is the pigmented fibrovascular layer in the front, and pigmented epithelial cells which are below the stroma. In other words, as a result of this process, it is much more difficult to fool a person than other forms of biometric technology. Uniqueness: A smaller than average size pupil can greatly reduce the amount of external light which is transmitted to the Retina. Finally, the iPhone 11 Pro and iPhone 11 Pro Max feature 6.1 Liquid Retina displays as well as Super Retina XDR displays, making them ideal devices for users who require the highest level of quality and detail. In this regard, when compared to the other Biometric modalities, precision is of utmost importance in Retinal Recognition. Disadvantages: a. For reliable identity verification, digital templates based on the patterns of the irises of a persons eyes can be used for comparison and matching. Will immersive technology evolve or solve cybercrime? 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). In terms of commercial adoption, iris recognition has surpassed that of recognition. They are used to diagnose and treat a wide range of medical conditions, including cancer, stroke, heart disease, and brain tumors. 2D recognition is affected by changes in lighting, the persons hair, the age, and if the person wear glasses. One of the best examples of this is the State of Illinois, where this modality was used in identifying welfare recipients to reduce fraud (this would occur when an individual would use several aliases to receive multiple payments). Patterns in the iris and retina are unique not only for each individual, remains intact throughout life under normal health condition. The method is fairly new, and not many use retina biometric devices. The retina's capillaries absorb the light better than other parts of the eye, so the scan is able to create a pattern of blood vessels - which is then measured and verified. Government-based security applications also, to a certain degree, also make use of Retinal Recognition. According to a study, only 20% of a scanning devices security is rejected as a result of a faulty retina scan. Like retinal scanning, iris recognition also boasts one of the lowest rates of false acceptance and false rejection. A single OCT machine can cost anywhere from $35,000 to more than $100,000, but used or refurbished units are significantly less expensive. Retinal recognition is almost exclusively deployed in applications where extremely high levels of security are a requirement. Eye color profiling, also known as eye pattern recognition, is a technique used to determine an individuals unique eye color. We also have to consider the advantages and disadvantages of each individual system. Fundus autofluorescence utilizes the natural fluorescent properties of lipofuscin within the retinal pigment epithelium to create an image of the retina. Immediately after this, it appears the true window, identical, and the user will simply believe that he has been mistaken. In this regard, he has written and published two books through CRC Press. b. Overall, there is a very negative attitude about using Retinal Recognition amongst the public, at least here in the United States. The biometric system eliminates the need to remember passwords. 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. Most smartphones, in the present day, have fingerprint scanners that allow the user quick access to the files on their phones. 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. One of the Biometric Templates which is used quite heavily in the e-Passport infrastructure is that of Iris Recognition. Save my name, email, and website in this browser for the next time I comment. Iris scanning is still not 100% reliable because the system will fail if the user has long eyelashes, different eye color, or a reflection in the cornea. This is because the scan area is so small, when compared to the other biometric modalities. Since iris patterns stay practically unchanged throughout a persons lifetime, iris recognition is one of the most accurate biometric modalities that are commonly deployed. a. The following table compares some of the biometric systems used lately, from the point of view of accuracy, cost, devices required and social acceptability. c. The eye from a dead person would deteriorate too fast to be useful, so no extra precautions have to been taken with retinal scans to be sure the user is a living human being. A retinal scan is performed by casting an unperceived beam of low-energy infrared light into a person's eye as they look through the scanner's eyepiece. Resistance to circumvention: But despite these key, strategic advantages, the e-Passport infrastructure is also prone to Cyber based attacks, given its heavy dependency upon a networked environment. Biometric authentication comes in play to release the users from the difficulties of remembering and protecting passwords. In retina scanner technology, blood vessels are mapped in a persons retina and this pattern is used to confirm identity. Scanning procedure is perceived by some as invasive. Externally visible; patterns imaged from a distance. Thus, in this regard, it is considered to be the most reliable Biometric Technology which is available in the marketplace today. enrolling in a retina scan biometric system can be tedious due to the requirement of multiple image capture, making the process feel uncomfortable for the user. In the next paragraphs, we will make an enumeration of the problems that these techniques can present: Signature recognition: However, it will be more accurate and secure. However, distinct differences exist which sets these two modalities apart that are suitable for specific use cases. CT scan machines are now widely used in hospitals and clinics all over the world. This has to do with leaning in and keeping their eye close to the scanning device in order for a scan to be accurate. Because the hand can be considered to be an external component of the human anatomy, it is prone to the harshness of the external environment. This includes military installations and bases, nuclear facilities, and laboratories where very high calibre research and development is taking place. Click on 'Write for us' to contact us. If the retina scanner is commercial, then it will be more expensive and only available to those who can afford it. As it has been described, the individual must remain perfectly still throughout the above-described process, especially when the raw images are being captured. 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. High equipment costs. FLoC delayed: what does this mean for security and privacy? Retinal scan is a highly dependable technology because it is highly accurate and difficult to spoof, in terms of identification. Has The Popularity of Technology Created More Money Making Opportunities? The iPhone 11 is also equipped with an A13 Bionic chip, which provides excellent performance in harsh water conditions, making it ideal for mobile professionals and students alike. The biometric system is a convenient method of tracking each employee in an organization because it provides authentic sign-in and sign-out data. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. b. b. Verification time is generally less than 5 seconds. The handy tool gathers all the information for you. What are the goodness and weakness about the current technology? This has led to debate about whether the retina scanner should be a commercial or open source technology. A retinal scan is a biometric technique that maps the unique patterns of a person's retina using a low-intensity light source. Retinal scans can therefore entail multiple attempts and quite a long time to get the best results in accurately verifying the user. Iris patterns are more robust than voices. It is also very convenient because it consists of an RFID antennae embedded into the microchip. When it comes to security and other related functions, there are clear advantages and disadvantages that biometrics brings to the table. Research shows that retinal scans are very accurate. Measurement accuracy can also be affected by severe astigmatism. The device is much better than a resource who would do the same job for a hefty salary. document.getElementById( "ak_js_2" ).setAttribute( "value", ( new Date() ).getTime() ); Fast and high-quality fingerprint scanning, Bluetooth-enabled secure fingerprint scanning, Advanced finger vein recognition technology, Auto tilt, dual iris, and face recognition for optimal security. Because of its stability and richness, it is almost impossible to spoof a retinal recognition system. If you have certain eye conditions, such as cataracts or glaucoma, your ability to use retina-scan technology may be compromised. b. If the user is wearing lenses (and usually doesnt) or vice versa. Copyright 2023 M2SYS Blog On Biometric Technology. b. In retina scanning, a noninvasive imaging technique that produces a picture of your back of the eye, your retina, is used. No direct physical contact is required between the person and the camera, making iris recognition completely non-intrusive. He also does Cybersecurity Consulting through his private practice, RaviDas Tech, Inc. Because of its stability, the retina possesses extremely high levels of accuracy. Though it requires special hardware to use, it can be easily integrated into other devices or systems. b. Iris recognition technology is an automated method of biometric authentication that utilizes software algorithms and video camera technology with minimal infrared illumination that can analyze minute textures of the iris. 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. Thus, it is also deemed to be the smallest Biometric Template of all. Disadvantages: a. The business was started in 2009, and has clients all over the world. The retina is the innermost layer of a . The position of the eye could be problematic. This same process is also used to create the Verification Template. 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. a. Non intrusive. In general, retinal scanning is considered to be a very accurate method of identification. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Our editorial team consists of a group of young, dedicated experts in robotics research, artificial intelligence, and machine learning. . They later released their paper, suggesting the use of photographs of these blood vessel patterns of the retina to identify people. Authentication techniques used by elearning vendors, Advantages and disadvantages of technologies. The system may offer various advantages to enterprises; however, if youre opting for it have a look at the disadvantages below: The authentication system only recognizes traits that were entered and fail to recognize the user if their physical traits change even the slightest. The system makes the authentication process quick and easy; however, it has other advantages, that are: 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. The manual process would be time-consuming; however, the biometric system eliminates the need for physical attendance. Biometric is an automatic authenticating technology that is found in most workplaces, in the present day. Twitch and YouTube abuse: How to stop online harassment.
