retinal scanning advantages and disadvantages

Given the complexity of retinal biometrics, it is hardly surprising that retinal scanning technology only enjoys a low commercial acceptance. Traditional authentication systems require the user to perform the cumbersome task of memorizing numerous passwords, personal identification numbers (PIN), pass-phrase, and answers to secret questions. These devices, which are used by high-end banks and corporations to improve safety, will be useful for this purpose. Disadvantages: 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. 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. Cheap technology. 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. If the data were stolen, they cant try to change their identification traits like they can change passwords during a security breach. Advantages And Disadvantages Of Retina Scans. The technology can be painful to use because users must lean in and keep their eye close to the screen for 30 seconds during a retina scan. Iris recognition can also provide a unique identity for citizens who do not own a passport or other identity cards, giving them access to governmental services. Subject being scanned must be close to the camera optics. Why this matters. Both retinal and iris scanning are ocular-based biometric technologies. The biometric system allows them to limit access to unauthorized personnel. We also have to consider the advantages and disadvantages of each individual system. They are pattern-dependent, not sight-dependent. 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). Optomap imaging provides a view of up to 80% (200 degrees) of the retina at one time. There are pros and cons to both options. During a retinal scan, the user must remove glasses, stare at a specific point, and hold their head still for the 10-15 seconds it takes to complete the scan. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. Vein Recognition Biometrics. The technology, however, has notable disadvantages including difficult image acquisition and limited user applications. Retina scanning is different from iris scanning, as this biometric technology used an image of your retinal blood vessel pattern as an identifying trait. M2SYS Blog holds all the rights to add, remove, modify content in this blog. A lot of memory for the data to be stored. Acceptability: Analysts predict CEOs will be personally liable for security incidents. How safe is an etinal scan? 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. Uniqueness: Very high accuracy. The retina scanner is a type of biometric scanner that uses the unique patterns in a persons retina to identify them. Iris recognition has gained more widespread commercial adoption between the two. If the distance is greater than this, then the scanning process must be repeated over again until it is correct. The handy tool gathers all the information for you. But its small size and bend requirements (which are designed to protect the card physically), limits the memory and processing resources. Requires camera equipment for user identification; thus, it is not likely to become popular until most PCs include cameras as standard equipment. It is the former which allows for both night and peripheral vision to take place. The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting. What are the pros and cons of iris recognition? They can be described as follows: The advantages. Self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. Externally visible; patterns imaged from a distance. This was the first study actually to suggest the use of the Retina as means to help confirm the identity of an individual. The retina is the innermost layer of a . Specialized fundus cameras consisting of an intricate microscope attached to a flash enabled camera are used in fundus photography. It is more prone to spoof attacks than retina recognition. 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. 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. Acquiring an image requires proper alignment and positioning. Very high accuracy. The result might be affected due to pupil size change. This is because the scan area is so small, when compared to the other Biometric modalities. This has to do with leaning in and keeping their eye close to the scanning device in order for a scan to be accurate. It has no public attitude problems as it is associated most commonly with authorized access. From here, an infrared light beam light is then shot into the eye, in order to fully illuminate the Retina. This blood vessel pattern is a reliable biometric characteristic for retinal scanners. Stolen company credentials used within hours, study says, Dont use CAPTCHA? Almost unaffected by the environment due to being protected by the cornea and the aqueous humor. Extremely intrusive. Because of the attention that is required by the end user, it can take numerous attempts and a long time to get the results which are required. Learn how your comment data is processed. A persons iris patterns can be used to generate digital templates that can be used for comparison and matching. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. Retinal recognition: The advantages and disadvantages. 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 Hand Geometry Recognition and Fingerprint Recognition. It is considered that is even less falsifiable than the manual signature recognition (although this last is already enough trustworthy). Two different scanners can be used to test whether they detect flaws that one does not. The system is still changing to become better. For example, it contains a microchip which can store up to three Biometric Templates of different modalities, thus offering a true multi-layered approach to security. The biometric system has many forms, and the most commonly used are fingerprint scanner, face recognition, and retina scanners. The views expressed in the guest posts do not necessarily reflect the views of M2SYS or M2SYS Blog. There is no scientific evidence to suggest that retinal scanning is harmful. The retina template generated is typically one of the smallest of any biometric technology. That means users cant rely on the safety of their data. http://www.biometricupdate.com/201307/explainer-retinal-scan-technology, http://www.biometricnewsportal.com/retina_biometrics.asp, http://link.springer.com/referenceworkentry/10.1007%2F978-0-387-73003-5_132, http://www.discoveriesinmedicine.com/Ra-Thy/Retinography.html, https://www.researchgate.net/publication/241635834_Retinal_recognition_Personal_identification_using_blood_vessels, Retinal recognition The ultimate biometric, http://www.slideshare.net/piyushmittalin/retinal-recognition, Breaking the Silo: Integrating Email Security with XDR, Password security: Using Active Directory password policy, Inside a DDoS attack against a bank: What happened and how it was stopped, Inside Capital Ones game-changing breach: What happened and key lessons, A DevSecOps process for ransomware prevention, How to choose and harden your VPN: Best practices from NSA & CISA. b. . This technique is currently used in two distinct forms: imaging of the retina and imaging of the blood vessels. Through a delicate sensor, a retinal scan examines the pattern of retina blood vessels, which remains unchanged from birth until death. The process involves the acquisition and processing of images, unique feature extraction, and template creation and matching. a. Disadvantages 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 is also a regular columnist for the Journal of Documents and Identity, a leading security publication based out of Amsterdam. It can be installed on its own or as part of the Retina CS platform for a unified vulnerability management solution. However, iris recognition is widely accepted as a commercially-viable modality compared to retinal scanning. Nowadays iris scan is preferred over retina scan due to its advantages. Since then, retina scanners have been used in a variety of settings, including security, banking, and healthcare. The retina is the innermost layer of a human eye. 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. It might take more than a few attempts to get the capture process right as eye scanners can be sensitive to reflection. Because of its stability, the Retina possesses extremely high levels of accuracy. Not only because of the uniqueness it possesses, the Retina also contains very rich information about an individual, just as much as the DNA Strand. Whenever you search in PBworks or on the Web, Dokkio Sidebar (from the makers of PBworks) will run the same search in your Drive, Dropbox, OneDrive, Gmail, Slack, and browsed web pages. 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. The Pros And Cons Of A Retina Scanner: Commercial Vs Open Source. Likewise, apps like WhatsApp also offer finger identification, that helps users keep their data protected from unwanted theft. Very high accuracy. A low-intensity light source is used in a retinal scan to generate a unique pattern of blood flow in the retina. This has led to debate about whether the retina scanner should be a commercial or open source technology. As a matter of fact, the false rejection and false acceptance rate of iris recognition is significantly lower than that of fingerprints. As a result, the Ability to Verify metric can be as low as 85% (other modalities are as high as 99% or even 100%). Retinal recognition is almost exclusively deployed in applications where extremely high levels of security are a requirement. A lot of memory for the data to be stored. Disadvantages: What is the difference between retinal scanning and iris recognition? The following table compares some of the biometric systems used lately, from the point of view of accuracy, cost, devices required and social acceptability. confocal scanning laser ophthalmoscope, ultra-widefield confocal scanning . This is because the scan area is so small, when compared to the other biometric modalities. 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. Contact the owner / RSS feed / This workspace is public, Drive, Dropbox, OneDrive, Gmail, Slack, and browsed web pages. You don't have permission to comment on this page. 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.'. As a result, security teams can use it to combat fraud. Over 20 years ago, a company known as Optos introduced optomap ultra-widefield retinal imaging. We have discussed above that identification with IDs or passwords can be a nerve-wrecking experience. We use cookies to give you the best experience on our site. Passwords, pins, security codes are hard to remember for some people. 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. b. No thanks, wed rather pay cybercriminals, Customer data protection: A comprehensive cybersecurity guide for companies, Online certification opportunities: 4 vendors who offer online certification exams [updated 2021]. Several experts have stated that retina scanners pose no health risks or other issues to users. Retina Scanning. 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. Hand Geometry: Our passion for technology brings biometric benefits to millions of people. The primary reasons for this are for both security and convenience. 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. There is no known way to replicate a retina. 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 position of the eye could be problematic. Just like the other biometric modalities, retinal recognition has its own set of pros and cons. For example, because of the sheer intrusiveness which is involved with it, many people perceive that it poses a serious health risk to the eye. Some biometric systems can face scanning issues if there is even a slight change, especially if the company is using retina scanning. It is considered that is even less falsifiable than the manual signature recognition (although this last is already enough trustworthy). Signature verification is designed to verify subjects based on the traits of their unique signature. Thus, Retinal Recognition is used primarily in Physical Access Entry applications, where extremely high levels of security are required. When compared to all the other biometric modalities, retinal recognition demands the highest levels of cooperation and motivation from the end-user to capture high quality, raw images. The interest of using the Retina as means for verification and/or identification goes back all the way to the 1930s. A retinal scan is a biometric technique that maps the unique patterns of a person's retina using a low-intensity light source. The iPhone 11 is Apples most recent smartphone, and it includes a number of exciting new features. The 5 biggest cryptocurrency heists of all time, Pay GDPR? The main light-sensing cells in the retina are comprised of two specific types of photoreceptor cells: rods and cones. f. It is standardized. It weighs more than 60 pounds, takes up an entire desk, and costs between $50,000 and $120,000 to build. d. Easy to use. b. 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. This requires that the end user must be in very close proximity to the Retinal scanning device. Will immersive technology evolve or solve cybercrime? Country Unlike the iris, the retina can be subjected to changes if an individual is afflicted with a disease or blindness. If the retina scanner is commercial, then it will be more expensive and only available to those who can afford it. Retinal scanning advantages and disadvantages Advantages: Resolution: 8 bits per pixel. Permanence: High social acceptability. b. Verification time is generally less than 5 seconds. As it has been described, the individual must remain perfectly still throughout the above-described process, especially when the raw images are being captured. It is also very convenient because it consists of an RFID antennae embedded into the microchip. While there have been some reports of minor discomfort associated with retinal scanning, such as dry eyes or headaches, these side effects are typically short-lived and do not pose any long-term health risks. the false rejection rate of retinal scanning technology stands at 1.8%, the false rejection and false acceptance rate of iris recognition is significantly lower than that of fingerprints, National Aeronautics and Space Administration (NASA), biometric identity verification and authentication. 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. Eye scanners use the unique patterns of the retina and/or the iris of individuals to determine their identity in a variety of ways. Iris patterns are more robust than voices. Any eyeglasses must be removed, in order to avoid any signal interference (in other words, this would cause the infrared light beam to reflect back into the scanning device without having captured any actual images). Now you can find what you're looking for wherever it lives. Iris recognition is used to secure airports, perform sensitive construction tasks, and operate in military operations. Each persons retina scan is distinguished by a few distinct characteristics. Taking all of this into consideration, the market applications are extremely limited for retinal recognition. Copyright 2023 M2SYS Blog On Biometric Technology. Advantages of the Iris for Identification. The term is used in conjunction with security systems that identify people based on a previous recording of one or more of their body characteristics. Thats because the system is reliable and enhances enterprise security. Quicker Authentication. Insert links to other pages or uploaded files. Authentication techniques used by elearning vendors, Advantages and disadvantages of technologies. Biometric authentication comes in play to release the users from the difficulties of remembering and protecting passwords. Nowadays, retinal scanning has also been deployed in a number of applications, including ATM identity verification and prevention of welfare fraud. 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). As a result of growing use, a growing number of employers are requiring retina scans as part of their job requirements. 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. Since then, the system has only seen immense improvements and aided business owners. This same process is also used to create the Verification Template. Using a contact lens is another method to spoof some iris sensors successfully. Taking all of this into consideration, the market applications are extremely limited for Retinal Recognition. 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. In this regard, he has written and published two books through CRC Press.

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. Advantages: Ease of use. Its a single device that keeps track of every sign in and employee access in a large enterprise. 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. Cookies are files stored in your browser and are used by most websites to help personalise your web experience. The Retina scanner can not only determine who has access to a building, but it can also help employers monitor employee performance. c. Comparisons of template records can take upwards of 10 seconds, depending on the size of the database. 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. a. How safe are eye (retina and iris) scanning technologies? Self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. This test does not use radiation or X-rays, and it is not intended to replace regular eye exams. c. An illness such as a cold can change a persons voice, making absolute identification difficult or impossible. 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. Fake positives are finger impressions made out of silicone to access sensitive data of organizations, making biometric security vulnerable. a. As mentioned earlier, the acceptance of retinal recognition by the general public is extremely low. In their work, they describe how every individual possesses a unique Retinal structure, because of the differing distribution of blood vessels. The password method is the cheapest and simplest technology, because it only requires elementary software resources. Ultimately, biometric authentication techniques are all about security. Advantages. First, there is much lower processing overhead required when examining the statistical closeness between the Verification and Enrollment Templates. Recent technological advancements have made the process much more pleasant. a. Just like the other biometric modalities, retinal recognition has its own set of pros and cons. The retina, unlike the iris, can experience changes in the same way that the eye can if it is affected by disease or blindness. Fundus photography involves photographing the rear of an eye, also known as the fundus. Retinal scan is a highly dependable technology because it is highly accurate and difficult to spoof, in terms of identification. This includes military installations and bases, nuclear facilities, and laboratories where very high caliber research and development is taking place. Disadvantages: Ruud Bolle, and Sharath Pankati. Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. Iris recognition: In fact, under optimal conditions, the error rate can be as low as 1 in 1 million. 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. In a variety of high-risk sectors, it is extremely useful to use retina scanners to implement strong biometric security protocols. 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. The process of enrollment and verification/identification in a retinal scanning system is the same as the process for other biometric technologies. The biometric system offers users the flexibility of using physical traits and eliminating the need for remembering passwords or pins. Stay up to date with the latest news, offers and special announcements. Retinal scans can therefore entail multiple attempts and quite a long time to get the best results in accurately verifying the user. Since retinal recognition templates are incredibly small, it is quite fast to confirm the identity of a person. High equipment costs. The second study by Dr. Paul Tower came out in the 1950s. As a result, individuals who do not sign their names in a consistent manner may have difficulty enrolling and verifying in signature verification. However, there is a negative public perception regarding retinal scanning due to its intrusive nature. The data provided by a company biometric is 100% authentic and reliable. If you have certain eye conditions, such as cataracts or glaucoma, your ability to use retina-scan technology may be compromised. Biometric is a technique that can provide all this requirements with quite lot reliability. If a condition or disease is found, the doctor will repeat the test with a . The next scientific study which confirmed the uniqueness of the Retina was conducted in the 1950s by a scientist known as Dr. Paul Tower. b. If there is a power shortage, no user can enter or exit. It has the stigma of consumer's thinking it is potentially harmful to the eye. a. From this comparative table we can deduce that the most adequate methodology is the fingerprint authentication. In fact, the procedure is generally considered to be safe and painless. Convenience. 2D recognition is affected by changes in lighting, the persons hair, the age, and if the person wear glasses. Therefore, retinal scans require a massive amount of cooperation from a user to capture high quality images. Requires camera equipment for user identification; thus, it is not likely to become popular until most PCs include cameras as standard equipment. Ravi is a Business Development Specialist for BiometricNews.Net, Inc., a technical communications and content marketing firm based out of Chicago, IL. Dr. John Daugman of Cambridge University later developed the algorithms, mathematical methods, and techniques to encode iris patterns and efficiently compare them. In this regard, when compared to the other Biometric modalities, precision is of utmost importance in Retinal Recognition. These devices are primarily used in physical access applications, and they are used in environments with extremely high levels of security and accountability. The process can be broken down as follows: In this first phase, the individual must place their eye into a tiny receptacle.
