retinal scanning advantages and disadvantages

Advantages and disadvantages of technologies - PBworks 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. 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. Iris recognition is an easy-to-use technology, wherein a person only needs to stand still in front of the camera, and the rest is taken care of by the technology behind it. Disadvantages: Disadvantages: a. Intrusive. Is the most economical biometric PC user authentication technique. However, distinct differences exist which sets these two modalities apart that are suitable for specific use cases. Try Dokkio Sidebar for free. The biometric system has many forms, and the most commonly used are fingerprint scanner, face recognition, and retina scanners. b. This image is used to screen for eye diseases and can be used to compare to images taken in future examinations. In fact, the procedure is generally considered to be . Advantages and Disadvantages of Biometric Identification In contrast, retinal pattern recognition obtains the internal part of the eye, i.e., the retinas vascular pattern. The Retina possesses two types of photoreceptors, which are: 1) the Rods; and 2) The Cones. This was the first study actually to suggest the use of the Retina as means to help confirm the identity of an individual. Both iris and retinal pattern recognition are eye-based biometrics. 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. As a result, security teams can use it to combat fraud. 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. Low accuracy. 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. 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 recognition: The advantages and disadvantages. The iris is the determining factor of a persons eye color. Both retinal and iris scanning are ocular-based biometric technologies. The iriss complex structure carries distinctive information, and under normal health conditions, it remains unchanged from early childhood to death of the individual. High social acceptability. The views expressed in the guest posts do not necessarily reflect the views of M2SYS or M2SYS Blog. Recent technological advancements have made the process much more pleasant. A visual inspection of the retina is frequently used to diagnose communicable diseases such as HIV/AIDS and chicken pox. The device is much better than a resource who would do the same job for a hefty salary. Iris is the visible ring on the front side of the eye that surrounds the pupil of ones eye. 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. 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. Throughout the entire human anatomy, it is the eye which captures the intrigue of both medical practitioners and research scientists. Furthermore, they can be used to diagnose and treat a wide range of medical conditions, are safe, and are relatively painless. CT scan machines are now widely used in hospitals and clinics all over the world. Retinal recognition: pros and cons - Keesing Platform Since every iris is unique to an individual, iris recognition makes for an ideal form of biometric verification. Nowadays, retinal scanning has also been deployed in a number of applications, including ATM identity verification and prevention of welfare fraud. Since retinal recognition templates are incredibly small, it is quite fast to confirm the identity of a person. Advantages: 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. Retina scanning is different from iris scanning, as this biometric technology used an image of your retinal blood vessel pattern as an identifying trait. Even if a retinal scan itself poses no danger to the eye, users sometimes complain of discomfort from the technology during the enrollment process. 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. The retina scanner is a type of biometric scanner that uses the unique patterns in a persons retina to identify them. Advantages: And used like the only identification system, is not excessively trustworthy, since it can be easily stolen, lost or simply forgotten at home. Because injuries are not always obvious in imaging or in retina examination, there is the possibility that injuries can be avoided or that injuries are more likely to have a significant visual impact than other types of injuries. This is because the scan area is so small, when compared to the other biometric modalities. 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. However, it will be more accurate and secure. The biometric system is yet to be mainstream, which is why the setup, integration, and hardware can be costly, especially for small businesses. Self-containment of smart card makes it resistant to attack as it does not need to depend upon potentially vulnerable external resources. In the end, Retinal scans can assist businesses in determining whether employees are who they say they are and in ensuring that they do. 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). It is a great way to monitor your eye health over time and check for any health problems that may arise. Most smartphones, in the present day, have fingerprint scanners that allow the user quick access to the files on their phones. When it comes to security and other related functions, there are clear advantages and disadvantages that biometrics brings to the table. As a result, individuals who do not sign their names in a consistent manner may have difficulty enrolling and verifying in signature verification. It has the stigma of consumer's thinking it is potentially harmful to the eye. a. This test does not use radiation or X-rays, and it is not intended to replace regular eye exams. The data provided by a company biometric is 100% authentic and reliable. Very high accuracy. 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). Contact the owner / RSS feed / This workspace is public, Drive, Dropbox, OneDrive, Gmail, Slack, and browsed web pages. Another similar Biometric modality is Retinal Recognition, which is the topic of this article. Simply put, it is virtually impossible to be falsely accepted by a retinal recognition system. These devices can also be used to detect conditions that, when they become detectable, have no symptoms and can have a negative impact on your vision. High equipment costs. 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. Performance: As mentioned earlier, the acceptance of Retinal Recognition by the general public is extremely low. The technology, however, has notable disadvantages including difficult image acquisition and limited user applications. Retinal scans can therefore entail multiple attempts and quite a long time to get the best results in accurately verifying the user. Retinal Scanning definition.

Biometric is a technique that can provide all this requirements with quite lot reliability. Through a delicate sensor, a retinal scan examines the pattern of retina blood vessels, which remains unchanged from birth until death. In other words, this is not written into the DNA structure of the individual and is not handed down to the offspring. Fake positives are finger impressions made out of silicone to access sensitive data of organizations, making biometric security vulnerable. Consequently, retinal scanning devices are costly. Government-based security applications, to a certain degree, also make use of retinal recognition. Advantages: Ease of use. Is Biometric Technology Worth the Cost? | CIO Insight 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 retina is the innermost layer of a . This is because the scan area is so small, when compared to the other Biometric modalities. b. It certainly offers pros that outweigh the cons; however, its still a system thats far from perfect. Why this matters. Thus, the need for Penetration Testing across all levels is required to make sure that all of the hidden security vulnerabilities can be discovered and quickly patched up. In fact, under optimal conditions, the error rate can be as low as 1 in 1 million. As a result, the Ability to Verify metric can be as low as 85% (other modalities are as high as 99% or even 100%). The primary function of the Retina is to feed visual information and cues into the brain so that it can further process. Little time of verification (about five seconds). Advantages: In retina scanning, a noninvasive imaging technique that produces a picture of your back of the eye, your retina, is used. Your eyes are not at risk as a result of the scan, and your overall health is not threatened. c. An illness such as a cold can change a persons voice, making absolute identification difficult or impossible. Though it requires special hardware to use, it can be easily integrated into other devices or systems. If there is a power shortage, no user can enter or exit. The process can be broken down as follows: In this first phase, the individual must place their eye into a tiny receptacle. It is considered that is even less falsifiable than the manual signature recognition (although this last is already enough trustworthy). In other words, the statistical probability of an impostor being falsely accepted by a Retinal Recognition System is almost nonexistent. The retina is regarded as one of the most reliable biometric modalities available in the marketplace nowadays. This has led to debate about whether the retina scanner should be a commercial or open source technology. Collectability: This stable uniqueness of iris texture becomes the basis of iris-based biometric recognition.

Just like the other Biometric modalities, Retinal Recognition has its own set of advantages and disadvantages. Highly protected, internal organ of the eye Externally visible; patterns imaged from a distance Iris patterns possess a high degree of randomness variability: 244 degrees-of-freedom entropy: 3.2 bits per square-millimeter uniqueness: set by combinatorial complexity Very expensive. 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 fiber-optical coherence tomography procedure improves resolution by using a small fiber-optic light to illuminate the retina. . a. This has to do with leaning in and keeping their eye close to the scanning device in order for a scan to be accurate. Signature recognition: Advantages: a. Because retinal blood vessels absorb light more readily than the surrounding tissue, the amount of reflection varies during the scan. b. It was produced by EyeDentify, a company formed in 1976, still the primary manufacturer of these devices. No direct physical contact is required between the person and the camera, making iris recognition completely non-intrusive. 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. Retinal scan - Wikipedia It weighs more than 60 pounds, takes up an entire desk, and costs between $50,000 and $120,000 to build. You consent to our cookies if you continue to use our website. 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. 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. While the texture of a persons iris remains stable over time, the accuracy of retinal scan measurement can be affected by disease. The second study by Dr. Paul Tower came out in the 1950s. Top 8 Advantages and Disadvantages of Biometric Regarding the former, the paper passport can be, to a certain degree, easily forged, replicated, or even hijacked. 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. Iris scanning is capable of capturing images of the intricate and unique structures of the iris even from a distance. 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. Acquiring an image requires proper alignment and positioning.
