All you do is give access to only those who matter. Hacking is an undying cyber theft, which means that hackers can easily manipulate stolen biometric data to create fake positives. Among the factors to consider is vulnerability scanners accuracy rate, as well as its reliability and scalability. It has the stigma of consumer's thinking it is potentially harmful to the eye. Why this matters. 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. 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. The result might be affected due to pupil size change. Even if the individual is fully cooperative, it can still be difficult to a collect a high-quality, raw image of the retina. 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. They are pattern-dependent, not sight-dependent. The process can be broken down as follows: In this first phase, the individual must place their eye into a tiny receptacle. Because of this, up to 400 unique data points can be captured from the Retina, unlike the fingerprint, where only 30-40 unique data points can be captured. Simply put, it is virtually impossible to be falsely accepted by a retinal recognition system. Externally visible; patterns imaged from a distance. The interest of using the Retina as means for verification and/or identification goes back all the way to the 1930s. In contrast, the e-Passport is a much secure identity document. Iris recognition obtains an image of the external eye, i.e., the iris surrounding the pupil, the white portion of the eye, the eyelids, and possibly the eyelash as well. HR officers dont have to browse heaps of attendance sheets to calculate leaves, late sign-ins, or overtime for individual employees. As it was discussed, the e-Passport is quickly becoming the replacement for the traditional paper passport. Be the first to rate this post. 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. If the data were stolen, they cant try to change their identification traits like they can change passwords during a security breach. You consent to our cookies if you continue to use our website. The scan only takes a second, and a flash will let you know when the device has finished taking an image of your retina. COMPARISON of the advantages and disadvantages of biometric technologies. 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 technology, however, has notable disadvantages including difficult image acquisition and limited user applications. Retinal photography usually costs between $30 and $60 per session. 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 pool of applications just described, and not grow any further from that point. Some biometric systems can face scanning issues if there is even a slight change, especially if the company is using retina scanning. 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. Advantages: In the next paragraphs, we will make an enumeration of the problems that these techniques can present: How safe is an etinal scan? The device is much better than a resource who would do the same job for a hefty salary. b. 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 5 biggest cryptocurrency heists of all time, Pay GDPR? No direct physical contact is required between the person and the camera, making iris recognition completely non-intrusive. b. High equipment costs. 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. Research by the National Institute of Standards and Technology (NIST) shows that iris scans are 90-99% accurate. 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. Regarding the former, the paper passport can be, to a certain degree, easily forged, replicated, or even hijacked. 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 biometric system is yet to be mainstream, which is why the setup, integration, and hardware can be costly, especially for small businesses. Our passion for technology brings biometric benefits to millions of people. . Please leave this field empty. Several high-risk sectors, such as border patrol and aviation, have chosen to use retina scans for their reliable biometric security protocols. Two different scanners can be used to test whether they detect flaws that one does not. As a feature, their main competitor is the password (or PIN code, on occasion), so a comparison between the two will reveal both their flaws and weaknesses. While the texture of a persons iris remains stable over time, the accuracy of retinal scan measurement can be affected by disease. Live capture is the act or method of gathering biometric data from an individual while the individual is physically present. In this regard, he has written and published two books through CRC Press. Once identity is verified through a retinal scan, there is almost no error given the high number of unique data points of the retina. Because of its stability, the retina possesses extremely high levels of accuracy. OCT scans, as opposed to other forms of biometrics, have a low inaccuracy level of 0.0001%. 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. Required fields are marked *. From here, an infrared light beam light is then shot into the eye, in order to fully 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. 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. 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. 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). Despite the fact that standard ophthalmoscopy, fluorescein angiography, and fundus photography have not been documented as having resulted in serious injuries, these procedures are not uncommon. Unless an individual has diabetes, glaucoma, high blood pressure, or cardiac disease, the Retina will hardly every change regarding structure or physiological makeup during the lifetime of the person. It has no public attitude problems as it is associated most commonly with authorized access. Click on 'Write for us' to contact us. In high-security offices, a retina scanner is the most common method of scanning. Disadvantages: In other words, the retina is to the eye as film is to a camera. But its small size and bend requirements (which are designed to protect the card physically), limits the memory and processing resources. 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. More info. Several experts have stated that retina scanners pose no health risks or other issues to users.

In fact, the procedure is generally considered to be . 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. You don't have permission to comment on this page. a. Intrusive. The retina is the innermost layer of a human eye. a. The user has to keep his/her eyes steady, especially in case of retinal scan. Biometric is a technique that can provide all this requirements with quite lot reliability. In a crisis, like a security breach, HR professionals cannot access the system remotely to try and eliminate sensitive data, which is a major disadvantage for the system. Government-based security applications, to a certain degree, also make use of retinal recognition. By scanning the retina, it is expected that high-tech equipment found in health care centers will be incorporated. c. Image captured at 500 dots per inch (dpi). Disadvantages: The physical authentication gives HR officers and organizations control over who has access to the office building, vaults, sensitive data, and lockers. From this comparative table we can deduce that the most adequate methodology is the fingerprint authentication. Ravis primary area of expertise is Biometrics. Stolen company credentials used within hours, study says, Dont use CAPTCHA? 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: The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula. c. An illness such as a cold can change a persons voice, making absolute identification difficult or impossible. b. It was discovered through his work that even identical twins have a very distinct and unique set of Retinas. Given the accuracy of its matching capabilities, retinal scan technology is difficult to spoof and is typically deployed in top-level security applications for authentication and identification.
