retinal scanning advantages and disadvantages
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. Thus, it is also deemed to be the smallest Biometric Template of all. In a variety of high-risk sectors, it is extremely useful to use retina scanners to implement strong biometric security protocols. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. Advantages: In other words, the statistical probability of an impostor being falsely accepted by a Retinal Recognition System is almost nonexistent. Retinal scans can therefore entail multiple attempts and quite a long time to get the best results in accurately verifying the user. Unlike the iris, the retina can be subjected to changes if an individual is afflicted with a disease or blindness. The Retina is the grouping of the blood vessels in the back of the eye, which connects to the front of the optic nerve which then goes into the brain. Your Email (required) Additionally, if the software has a bug or fails due to any reason, it will restrict access to users until the software is restored. This site uses cookies to provide services, personalise ads and to analyse traffic. 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. Retinal Scanning definition. 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. 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. Iris patterns possess a high degree of randomness . These devices are primarily used in physical access applications, and they are used in environments with extremely high levels of security and accountability. Its a single device that keeps track of every sign in and employee access in a large enterprise. Passwords, pins, security codes are hard to remember for some people. 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. Nessus offers a broader range of vulnerabilities than OpenVAS. The Smart Cards are very useful since they can be easily combined with other authentication systems, serving as storage system. Try Dokkio Sidebar for free. 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. Iris pattern recognition tends to be more acceptable to users compared to retinal pattern recognition. The position of the eye could be problematic. This stable uniqueness of iris texture becomes the basis of iris-based biometric recognition. It is also very convenient because it consists of an RFID antennae embedded into the microchip. Limitations: Lower resolution (10 m); poor resolution of retinal layers; slower image capture; no eye tracking feature. 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. Besides, sometimes they are combined with cryptography methods, which makes them more difficult (more expensive) to implement. One of the Biometric Templates which is used quite heavily in the e-Passport infrastructure is that of Iris Recognition. 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. 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 acceptance of retinal scans by the general public is extremely low due to its inconvenient and invasive nature. 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]. All you do is give access to only those who matter. He also does Cybersecurity Consulting through his private practice, RaviDas Tech, Inc. And used like the only identification system, is not excessively trustworthy, since it can be easily stolen, lost or simply forgotten at home. Advantages And Disadvantages Of Retina Scans. You don't have permission to comment on this page. Once identity is verified through a retinal scan, there is almost no error given the high number of unique data points of the retina. a. Therefore, retinal scans require a massive amount of cooperation from a user to capture high quality images. 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. Little time of verification (about five seconds). Likewise, apps like WhatsApp also offer finger identification, that helps users keep their data protected from unwanted theft. The identification of the retina and the identification of the iris is becoming more critical than ever. In the next paragraphs, we will make an enumeration of the problems that these techniques can present: Just like the other biometric modalities, retinal recognition has its own set of pros and cons. The biometric system has many forms, and the most commonly used are fingerprint scanner, face recognition, and retina scanners. A medical diagnostic system that uses infrared laser scanning is also available. Contact the owner / RSS feed / This workspace is public, Drive, Dropbox, OneDrive, Gmail, Slack, and browsed web pages. . Both techniques use near-infrared light to illuminate the object (iris or retina) of interest. Self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. 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. It is also possible that users will experience discomfort while enrollment is taking place. Experts acquire digital images of retinal patterns by projecting a low-intensity beam of visible or infrared light into a persons eye and scanning the retina. The iris regulates the amount of light that enters the eye by opening and closing the pupil, which is crucial in maintaining a proper line of vision. Is Retinal Scanning Harmful. The process involves the acquisition and processing of images, unique feature extraction, and template creation and matching. b. In the end, Retinal scans can assist businesses in determining whether employees are who they say they are and in ensuring that they do. If there is a power shortage, no user can enter or exit. 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. But iris spoof attacks are possible even with a high-quality photograph. With the cost of adopting iris recognition technology expected to decrease, iris scanning technology is expected to dominate the global market for biometric identity verification and authentication. By continuing to use our website without changing the settings, you are agreeing to our use of cookies. 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. Light from a small fiber-optic device, such as a fiber-OCT, is used to illuminate the retina. 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. Though it requires special hardware to use, it can be easily integrated into other devices or systems. Hacking is an undying cyber theft, which means that hackers can easily manipulate stolen biometric data to create fake positives. This technique is currently used in two distinct forms: imaging of the retina and imaging of the blood vessels. 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. Disadvantages: Disadvantages: As it was discussed, the e-Passport is quickly becoming the replacement for the traditional paper passport. The next scientific study which confirmed the uniqueness of the Retina was conducted in the 1950s by a scientist known as Dr. Paul Tower. 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. c. An illness such as a cold can change a persons voice, making absolute identification difficult or impossible. In the next paragraphs, we will make an enumeration of the problems that these techniques can present: a. 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. Simply put, it is virtually impossible to be falsely accepted by a retinal recognition system. Light passes through the optic nerve and sends electrical impulses to the brain via this layer. b. Moreover, they also require a person to stay still and avoid extra movements. The intricate iris patterns carry an astonishing amount of information, including 200 unique spots, while retinal scanning gathers unique features from the blood vessels. As it has been described, the individual must remain perfectly still throughout the above-described process, especially when the raw images are being captured. CT scan machines are now widely used in hospitals and clinics all over the world. Here are a few reasons why traits might change: In such situations, the authentication method needs to be changed to grant authorized user access, which can be inconvenient. b. Verification time is generally less than 5 seconds. Disadvantages. In fact, under optimal conditions, the error rate can be as low as 1 in 1 million. This problem can become further exacerbated if the pupil constricts even further because of inconsistent lighting conditions. High social acceptability. A single OCT machine can cost anywhere from $35,000 to more than $100,000, but used or refurbished units are significantly less expensive. The Digital Signature is very difficult to falsify, since is encrypted by complicated mathematic operations. a. Using a contact lens is another method to spoof some iris sensors successfully. On the other hand, this system is easily attackable, since he is quite simple to obtain the data from a person, either extracting the information to the person itself using deceits, or attacking the software of the system. The major phases in the iris pattern recognition process include iris scan for image acquisition, iris localization for distinguishing the iris from the rest of the eye, feature extraction, and template creation, followed by matching. It has the stigma of consumer's thinking it is potentially harmful to the eye. DNA: Both iris and retinal pattern recognition are eye-based biometrics. Disadvantages: Nowadays, retinal scanning has also been deployed in a number of applications, including ATM identity verification and prevention of welfare fraud. What is the difference between retinal scanning and iris recognition? Uniqueness: Iris Recognition and Retina Scanning are the physiological biometrics methods for identifying a person or verifying a persons identity. The Most Asked Questions. With the advancement of CT technology, patients can now receive the exact information and treatment they require to live and be healthy. That means users cant rely on the safety of their data. Since then, retina scanners have been used in a variety of settings, including security, banking, and healthcare. They are used to diagnose and treat a wide range of medical conditions, including cancer, stroke, heart disease, and brain tumors. In contrast, retinal pattern recognition obtains the internal part of the eye, i.e., the retinas vascular pattern. Some biometric systems can face scanning issues if there is even a slight change, especially if the company is using retina scanning. b. To get the best quality, raw images of the Retina, this light is shone into the eye in a 360-degree manner. Thus, Retinal Recognition is used primarily in Physical Access Entry applications, where extremely high levels of security are required. Weigh the following factors as you consider implementing biometric technology into your business: Pros Cons; Learn how your comment data is processed. . 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. The best OCT machines on the market are provided by the brand Zeiss, which specializes in ophthalmologic devices. In other words, as a result of this process, it is much more difficult to fool a person than other forms of biometric technology. 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. Ravi Das is a Cybersecurity Consultant and Business Development Specialist. The views expressed in the guest posts do not necessarily reflect the views of M2SYS or M2SYS Blog. They are pattern-dependent, not sight-dependent. Scanning procedure is perceived by some as invasive. The biometric system is a convenient method of tracking each employee in an organization because it provides authentic sign-in and sign-out data. A retinal scan is a biometric technique that maps the unique patterns of a persons retina using a low-intensity light source. If the retina scanner is open source, then it will be less expensive and available to everyone. In other words, this is not written into the DNA structure of the individual and is not handed down to the offspring. 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. Would you like to be part of this team? b. Verification time is about five seconds. With the latter, processing a paper passport can take time, especially at the customs and immigrations line at the country of destination. A lot of memory for the data to be stored. But its small size and bend requirements (which are designed to protect the card physically), limits the memory and processing resources. Biometric is a technique that can provide all this requirements with quite lot reliability. Hard to use; Difficult to integrate with other systems; The position of the eye could be problematic. If you have a potential risk of developing a retina condition, a retina scan can help your eye doctor determine your risk. Early detection of retinal disease, which enables early treatment and protection against complications or vision loss; A diabetic screening - retinal eye scans can spot early signs of eye damage caused by diabetes, even before you notice any symptoms; Corneal topography, facilitating advanced contact lenses fittings; Some disadvantages of the . a. A higher average for matching performance. As we have seen, there are numerous applications for Biometric Technology. Except for the DNA strand, it is the retina which possesses the greatest number of differing data points in the entire human anatomy. Quicker Authentication. Now you can find what you're looking for wherever it lives. Disadvantages. 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. Require specialized devices so that it can be expensive. The first retina scanner was developed in the late 1970s by American ophthalmologist, Dr. Joseph J. Atick. IRIS solutions can help eye care professionals diagnose Diabetic Retinopathy and macular edema, but IRC . 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. It is a great way to monitor your eye health over time and check for any health problems that may arise. 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. While the system is reliable and handy, the cost is not easy on the pocket. There is the possibility that infrared rays could cause damage to the retina. Cheap technology. They can be described as follows: The advantages. He now digs deeper into the advantages and disadvantages of retinal recognition. Despite these shortcomings, retina scan is a highly secure method of identification and immune to spoof attacks. 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. The Digital Signature is very difficult to falsify, since is encrypted by complicated mathematic operations. Measurement accuracy can also be affected by severe astigmatism. . PBworks / Help Each one has advantages and disadvantages, including range, accuracy, costs . It has no public attitude problems as it is associated most commonly with authorized access. Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. Signature verification is designed to verify subjects based on the traits of their unique signature. Advantages of the Iris for Identification. Hand Geometry: b. What are the pros and cons of iris recognition? Advantages: Disadvantages: Even blind people can enroll successfully. Biometric is a technique that can provide all this requirements with quite lot reliability. The primary function of the Retina is to feed visual information and cues into the brain so that it can further process. 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. Please leave this field empty. For some people it is very intrusive, because is still related to criminal identification. Ultimately, the decision about whether to make the retina scanner commercial or open source depends on what is more important: accuracy and security, or affordability and accessibility. The handy tool gathers all the information for you. It is a physiological feature of the retina that remains constant throughout a persons life. a. Live capture is the act or method of gathering biometric data from an individual while the individual is physically present. This includes military installations and bases, nuclear facilities, and laboratories where very high caliber research and development is taking place. 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). In terms of commercial adoption, iris recognition has surpassed that of recognition. Retina scanning occurs when a beam of infrared light is projected into somebody's eye via an eyepiece. Non intrusive. It can be installed on its own or as part of the Retina CS platform for a unified vulnerability management solution. From this comparative table we can deduce that the most adequate methodology is the fingerprint authentication. Advantages: The Pros And Cons Of A Retina Scanner: Commercial Vs Open Source. We have discussed above that identification with IDs or passwords can be a nerve-wrecking experience. Overall, there is a very negative attitude about using Retinal Recognition amongst the public, at least here in the United States. Because of these strategic advantages, Retinal Recognition has been termed as the Ultimate Biometric of All. 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. c. Cheap technology. 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. The process can be broken down as follows: In this first phase, the individual must place their eye into a tiny receptacle. Iris biometrics are similar to retina biometrics, except they use the unique pattern of a person's iris instead of the retina. Free Valentines Day cybersecurity cards: Keep your love secure! 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. When it comes to security and other related functions, there are clear advantages and disadvantages that biometrics brings to the table. The user has to keep his/her eyes steady, especially in case of retinal scan. Performance: The iris is the pigmented, annular muscular curtain near the front of the eye, which controls the size and diameter of the pupil. He also possesses the Certified in Cybersecurity (CC) cert from the ISC2. Non intrusive. The shape of the hand can also be greatly influenced to a certain degree by weight loss and weight gain . Our passion for technology brings biometric benefits to millions of people. 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. The blood vessels within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting. a. The password method is the cheapest and simplest technology, because it only requires elementary software resources. Regarding the former, the paper passport can be, to a certain degree, easily forged, replicated, or even hijacked. 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. Retinal scan is a highly dependable technology because it is highly accurate and difficult to spoof, in terms of identification. Government-based security applications, to a certain degree, also make use of retinal recognition. Even if the individual is fully cooperative, it can still be difficult to a collect a high quality, raw image of the Retina. Disadvantages: a. Intrusive. As a result, security teams can use it to combat fraud. Very expensive Given the complexity of retinal biometrics, it is hardly surprising that retinal scanning technology only enjoys a low commercial acceptance. It is considered that is even less falsifiable than the manual signature recognition (although this last is already enough trustworthy). Iris scanners are quite expensive, making them mostly accessible to governments and large corporations. The Retina scanner can not only determine who has access to a building, but it can also help employers monitor employee performance. 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. Permanence. There is no scientific evidence to suggest that retinal scanning is harmful. If the data were stolen, they cant try to change their identification traits like they can change passwords during a security breach. However, distinct differences exist which sets these two modalities apart that are suitable for specific use cases. Fundus autofluorescence utilizes the natural fluorescent properties of lipofuscin within the retinal pigment epithelium to create an image of the retina.
