In the next paragraphs, we will make an enumeration of the problems that these techniques can present: a. Advantages: Ease of use. b. Biometric is a technique that can provide all this requirements with quite lot reliability. They can be described as follows: The advantages. As a result, individuals who do not sign their names in a consistent manner may have difficulty enrolling and verifying in signature verification. Resolution: 8 bits per pixel. Click on 'Write for us' to contact us. Since every iris is unique to an individual, iris recognition makes for an ideal form of biometric verification. . In other words, the retina is to the eye as film is to a camera. If the data were stolen, they cant try to change their identification traits like they can change passwords during a security breach. This, in turn, can also have a huge impact on the quality of the Enrollment and Verification Templates as well. Unlike the iris, the retina can be subjected to changes if an individual is afflicted with a disease or blindness. Iris recognition: One of the Biometric Templates which is used quite heavily in the e-Passport infrastructure is that of Iris Recognition. Retinal scanning: Performance: 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. Advantages And Disadvantages Of Retina Scans. He also possesses the Certified in Cybersecurity (CC) cert from the ISC2. Once the data is stolen, no one can do anything about it because it cant be altered. For example, banks are investing in affordable mobile app development and biometric where users can sign using the fingerprint on their smartphones! The retina scan is one of the most precise forms of biometric technology, with very high reliability. 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. 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. Genetic factors actually do not dictate the composition of the blood vessel pattern which make up the Retina. As a result, security teams can use it to combat fraud. In this regard, he has written and published two books through CRC Press. a. c. An illness such as a cold can change a persons voice, making absolute identification difficult or impossible. Save my name, email, and website in this browser for the next time I comment. a. Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. . 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. Except for the DNA strand, it is the retina which possesses the greatest number of differing data points in the entire human anatomy. The biometric system has many forms, and the most commonly used are fingerprint scanner, face recognition, and retina scanners. This is in sharp contrast to Iris Recognition, where images can be collected from a very far distance. Like retinal scanning, iris recognition also boasts one of the lowest rates of false acceptance and false rejection. It offers different modes like retina recognition, fingerprint, or face scanner. 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). The position of the eye could be problematic. It impossible that the system made mistakes. From this comparative table we can deduce that the most adequate methodology is the fingerprint authentication. The Retina is deemed to be very stable, and hardly ever changes over the lifetime an individual. He is also a regular columnist for the Journal of Documents and Identity, a leading security publication based out of Amsterdam. The best OCT machines on the market are provided by the brand Zeiss, which specializes in ophthalmologic devices. Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. Passwords, pins, security codes are hard to remember for some people. 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. Advantages: It has the stigma of consumer's thinking it is potentially harmful to the eye. Among all the biometrics in use today, eye biometrics (iris and retina) offers the highest level of uniqueness, universality, permanence, and accuracy, since iris and retina are an individuals unique biological traits. This process can take as long as a few minutes. 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. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. What are the goodness and weakness about the current technology? 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). With the latter, processing a paper passport can take time, especially at the customs and immigrations line at the country of destination. Taking all of this into consideration, the market applications are extremely limited for retinal recognition. Overall, the effectiveness and viability of retinal recognition can be examined against seven criteria which are also used by the biometrics industry here in the United States: Universality: Just like the other biometric modalities, retinal recognition has its own set of pros and cons. 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. 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. d. Very expensive. In contrast, retinal pattern recognition obtains the internal part of the eye, i.e., the retinas vascular pattern. The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula. No votes so far! On a much more scientific level, the Retina possesses multiple layers of sensory tissue as well as millions upon millions of photoreceptors. Advantages: Significantly improved resolution (1 m); more images taken; eye tracking feature. However, distinct differences exist which sets these two modalities apart that are suitable for specific use cases.

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. Eye color profiling, also known as eye pattern recognition, is a technique used to determine an individuals unique eye color. Contact the owner / RSS feed / This workspace is public, Drive, Dropbox, OneDrive, Gmail, Slack, and browsed web pages. FLoC delayed: what does this mean for security and privacy? This imaging method uses a dim red light to reflect off the retina and optic nerves. 2D recognition is affected by changes in lighting, the persons hair, the age, and if the person wear glasses. In the end, Retinal scans can assist businesses in determining whether employees are who they say they are and in ensuring that they do. One of the simplest biometric scanner devices for use in your office is the retina scanner. b. It seems that retinal recognition will only occupy a very limited pool of applications. 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. Require specialized devices so that it can be expensive. Ruud Bolle, and Sharath Pankati. Permanence. Difficult to integrate with other systems. 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. 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. Advantages and Disadvantages of Biometric Authentication. A retinal scan is performed by casting . 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. 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. Common biometric security implementations include fingerprinting, hand scanning, iris scanning, retina scanning, facial recognition, or voice recognition hardware and software. Has The Popularity of Technology Created More Money Making Opportunities? 2D recognition is affected by changes in lighting, the persons hair, the age, and if the person wear glasses. Passwordless authentication Why is it more secure? There is no scientific evidence to suggest that retinal scanning is harmful. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. Among the factors to consider is vulnerability scanners accuracy rate, as well as its reliability and scalability. a. b. Moreover, they also require a person to stay still and avoid extra movements. The result might be affected due to pupil size change. Limitations: Lower resolution (10 m); poor resolution of retinal layers; slower image capture; no eye tracking feature. 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. b. Nowadays, retinal scanning has also been deployed in a number of applications, including ATM identity verification and prevention of welfare fraud. Self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. The Retina possesses two types of photoreceptors, which are: 1) the Rods; and 2) The Cones. The biometric system offers users the flexibility of using physical traits and eliminating the need for remembering passwords or pins. CT scan machines are now widely used in hospitals and clinics all over the world. Although there are some concerns, there are no long-term issues with the technology. Many businesses have begun to use this type of unique identification for their employees. All rights reserved. The scan only takes a second, and a flash will let you know when the device has finished taking an image of your retina. Each one has advantages and disadvantages, including range, accuracy, costs . Please leave this field empty. If there is a power shortage, no user can enter or exit. If a condition or disease is found, the doctor will repeat the test with a . b. How safe are eye (retina and iris) scanning technologies? In high-security offices, a retina scanner is the most common method of scanning. 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. Ravi Das is a Cybersecurity Consultant and Business Development Specialist. Is the most economical biometric PC user authentication technique. b. b. Iris biometrics are similar to retina biometrics, except they use the unique pattern of a person's iris instead of the retina. This image is used to screen for eye diseases and can be used to compare to images taken in future examinations. b. Verification time is generally less than 5 seconds. The Pros And Cons Of A Retina Scanner: Commercial Vs Open Source. Iris scanning is capable of capturing images of the intricate and unique structures of the iris even from a distance. As mentioned earlier, the acceptance of retinal recognition by the general public is extremely low. In other words, as a result of this process, it is much more difficult to fool a person than other forms of biometric technology. retina blood vessels are examined during a delicate retina scan that remains unchanged from birth until death. Likewise, apps like WhatsApp also offer finger identification, that helps users keep their data protected from unwanted theft. And used like the only identification system, is not excessively trustworthy, since it can be easily stolen, lost or simply forgotten at home. This layer of tissue detects light and creates electrical impulses that are sent through the optic nerve to the brain which enables a person to see. Because of its stability and richness, it is almost impossible to spoof a Retinal Recognition system. This type of scan is very difficult to fake because no technology exists that . Ultimately, biometric authentication techniques are all about security. While rods generally function in dim lighting conditions and are responsible for black-and-white vision, cones are built for brighter lighting conditions and are in charge of recognizing colour. Will immersive technology evolve or solve cybercrime? The Smart Cards are very useful since they can be easily combined with other authentication systems, serving as storage system. A higher average for matching performance. 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). The very high accuracy, attained in iris recognition today, suggests it to be a very promising biometric for authentication purposes. Retinal scans map the unique patterns of a person's retina. 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. These devices are primarily used in physical access applications, and they are used in environments with extremely high levels of security and accountability. c. Comparisons of template records can take upwards of 10 seconds, depending on the size of the database. Biometrics Personal Identification in Networked Society: Anil Jain. 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). Simply put, it is virtually impossible to be falsely accepted by a retinal recognition system.

The size of the Retinal Enrollment Template is only at 96 bytes. Infosec, part of Cengage Group 2023 Infosec Institute, Inc. A persons voice can be easily recorded and used for unauthorised PC or network. Thus, it is considered to be a very stable Biometric modality, when compared to some of the others (such as Facial Recognition or even Fingerprint Recognition). A visual inspection of the retina is frequently used to diagnose communicable diseases such as HIV/AIDS and chicken pox. Disadvantages: 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). Very expensive. Disadvantages: a. Intrusive. Advantages of the Iris for Identification. While the system is reliable and handy, the cost is not easy on the pocket. Your eyes are not at risk as a result of the scan, and your overall health is not threatened. What is the difference between retinal scanning and iris recognition? If you have a potential risk of developing a retina condition, a retina scan can help your eye doctor determine your risk. We have discussed above that identification with IDs or passwords can be a nerve-wrecking experience. and biometric where users can sign using the fingerprint on their smartphones! Extremely intrusive. A lot of memory for the data to be stored. If you have diabetes, retinoblastoma, or glaucoma, your eye doctor may advise you to have a retina scan. We use cookies to give you the best experience on our site. Fingerprint: It has no public attitude problems as it is associated most commonly with authorized access. Disadvantages Disadvantages: This blood vessel pattern is a reliable biometric characteristic for retinal scanners. b. Digging the government database or awaiting response of a government agency for identity verification can be painfully slow process. The password method is the cheapest and simplest technology, because it only requires elementary software resources. Required fields are marked *. Very expensive . The Retina scanner can not only determine who has access to a building, but it can also help employers monitor employee performance. Retina Scanning. Each persons retina scan is distinguished by a few distinct characteristics. The Smart Cards are very useful since they can be easily combined with other authentication systems, serving as storage system. 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. Resistance to circumvention: Some biometric systems can face scanning issues if there is even a slight change, especially if the company is using retina scanning. A Retina Scanner, also known as an Iris scanner, is a device used for biometric identification. Scanning procedure is perceived by some as invasive. Free Valentines Day cybersecurity cards: Keep your love secure! Retinal photography usually costs between $30 and $60 per session. Non intrusive. c. It is not valid for arthritic person, since they cannot put the hand on the scanner properly. Through a delicate sensor, a retinal scan examines the pattern of retina blood vessels, which remains unchanged from birth until death. The system is still changing to become better. This procedure does not require focusing on the camera. This is, of course, has numerous advantages to it. c. Very expensive After this has been done, the Enrollment Template is then created. Weigh the following factors as you consider implementing biometric technology into your business: Pros Cons; The following table compares some of the biometric systems used lately, from the point of view of accuracy, cost, devices required and social acceptability. The retina template generated is typically one of the smallest of any biometric technology. Consequently, retinal scanning devices are costly. Signature verification is designed to verify subjects based on the traits of their unique signature. The process involves the acquisition and processing of images, unique feature extraction, and template creation and matching. c. An illness such as a cold can change a persons voice, making absolute identification difficult or impossible. There is no known way to replicate a retina. 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. Aside from its incredible security, the iPhone 11s retina scanner is extremely inexpensive and effectively perfect in terms of providing maximum security to areas where normally only authorized personnel are present. Signature verification is designed to verify subjects based on the traits of their unique signature. b. Hard to use; Difficult to integrate with other systems; The position of the eye could be problematic. 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. Low accuracy. Fundus photography involves photographing the rear of an eye, also known as the fundus. Nowadays iris scan is preferred over retina scan due to its advantages. Even if a retinal scan itself poses no danger to the eye, users sometimes complain of discomfort from the technology during the enrollment process. It has the stigma of consumer's thinking it is potentially harmful to the eye. a. On the other hand, iris recognition is considered more user friendly as it uses contactless digital photography to precisely verify identity. 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 single OCT machine can cost anywhere from $35,000 to more than $100,000, but used or refurbished units are significantly less expensive. Authentication techniques used by elearning vendors, Advantages and disadvantages of technologies. As it was discussed, the e-Passport is quickly becoming the replacement for the traditional paper passport. The 5 biggest cryptocurrency heists of all time, Pay GDPR? 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. 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. Retina scanners are devices that capture images of the unique patterns on a persons retina, which is the innermost layer of the eye. The acceptance of retinal scans by the general public is extremely low due to its inconvenient and invasive nature. The Iris is located in the front of the eye, and its primary function is to allow the requisite amount of light into the eye which is necessary to maintain a proper line of vision. Government-based security applications also, to a certain degree, also make use of Retinal Recognition.
