Advantages and Disadvantages of Biometric Identification The intricate iris patterns carry an astonishing amount of information, including 200 unique spots, while retinal scanning gathers unique features from the blood vessels. Quicker Authentication. Each persons retina scan is distinguished by a few distinct characteristics. The Pros And Cons Of A Retina Scanner: Commercial Vs Open Source. 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 All you do is give access to only those who matter. Immediately after this, it appears the true window, identical, and the user will simply believe that he has been mistaken. Biometric Technology Advantages and Disadvantages. 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. Even if the individual is fully cooperative, it can still be difficult to a collect a high quality, raw image of the Retina. This problem can become further exacerbated if the pupil constricts even further because of inconsistent lighting conditions. For reliable identity verification, digital templates based on the patterns of the irises of a persons eyes can be used for comparison and matching. Our passion for technology brings biometric benefits to millions of people. 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. Weigh the following factors as you consider implementing biometric technology into your business: Pros Cons; The first type of imaging is based on standard equipment that can image 45o of the retina. c. Comparisons of template records can take upwards of 10 seconds, depending on the size of the database. Retinal scan - Wikipedia a. No votes so far! You consent to our cookies if you continue to use our website. c. It is not valid for arthritic person, since they cannot put the hand on the scanner properly. Besides, sometimes they are combined with cryptography methods, which makes them more difficult (more expensive) to implement. The system may offer various advantages to enterprises; however, if youre opting for it have a look at the disadvantages below: The authentication system only recognizes traits that were entered and fail to recognize the user if their physical traits change even the slightest. In an eye scan of the retina, an unperceived beam of low-energy infrared light casts a beam into the eye as the patient looks through its eyepiece. The biometric system only allows access to authorized personnel and keeps out intruders. 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 Advantages of High-Resolution Retinal Imaging - Downtown Eyes How accurate are retinal scanning and iris recognition? Retinal scanning and iris recognition are two of the most accurate and reliable biometric modalities used for identity verification and authentication. Very high accuracy. Advantages and Disadvantages of Biometric Authentication. Retina Scanning. Once identity is verified through a retinal scan, there is almost no error given the high number of unique data points of the retina. Its a single device that keeps track of every sign in and employee access in a large enterprise. The biometric system has many forms, and the most commonly used are fingerprint scanner, face recognition, and retina scanners. It is considered that is even less falsifiable than the manual signature recognition (although this last is already enough trustworthy). The biometric system is a convenient method of tracking each employee in an organization because it provides authentic sign-in and sign-out data. 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: In fact, under optimal conditions, the error rate can be as low as 1 in 1 million. Iris Biometrics. The process involves the acquisition and processing of images, unique feature extraction, and template creation and matching. Because of this, a travelers identity can be instantaneously confirmed in just a matter of seconds, by merely flashing the e-Passport in front of the e-Passport reader. In retina scanning (a type of eye scanning similar to the way a microscope is used), the eye scanner must be close to the patient, whereas in iris recognition, a normal photo-capture process, the eye scanner can be taken from afar as well. Retinal scanning is a technology used to identify individuals by their unique patterns of blood vessels in the retina, located in the back of the eye. This is, of course, has numerous advantages to it. The very high accuracy, attained in iris recognition today, suggests it to be a very promising biometric for authentication purposes. It used infrared light to illuminate the retinas blood vessel pattern. Specialized fundus cameras consisting of an intricate microscope attached to a flash enabled camera are used in fundus photography. Fundus photography - Wikipedia c. it is one of the most developed biometrics Retinal scanning: This has to do with leaning in and keeping their eye close to the scanning device in order for a scan to be accurate. Employees can just use the retina or fingerprint scanner to sign in to record their attendance. Live capture is the act or method of gathering biometric data from an individual while the individual is physically present. Disadvantages. Be the first to rate this post. 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). Any sudden or unintentional movement can negatively affect the lens alignment of the aperture which is used to transmit the infrared light beam into the Retina. In general, retinal scanning is considered to be a very accurate method of identification. 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. What are the goodness and weakness about the current technology?Facial recognition:Voice recognition:Signature recognition:DNA:Retinal scanning:Iris recognition:Fingerprint:Hand Geometry: This includes military installations and bases, nuclear facilities, and laboratories where very high caliber research and development is taking place. Resolution: 8 bits per pixel. If you have a potential risk of developing a retina condition, a retina scan can help your eye doctor determine your risk. b. This, in turn, can also have a huge impact on the quality of the Enrollment and Verification Templates as well. This procedure does not require focusing on the camera. Iris scanning is capable of capturing images of the intricate and unique structures of the iris even from a distance. Fundus photography involves photographing the rear of an eye, also known as the fundus. 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. Consequently, retinal scanning devices are costly. 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. 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. Since retinal recognition templates are incredibly small, it is quite fast to confirm the identity of a person. 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. COMPARISON of the advantages and disadvantages of biometric technologies. c. it is one of the most developed biometrics, e. Small storage space required for the biometric template, reducing the size of the database memory required. 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. 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. 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. 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. What Is Biometric Authentication? A Complete Overview Free Valentines Day cybersecurity cards: Keep your love secure! Iris biometrics are similar to retina biometrics, except they use the unique pattern of a person's iris instead of the retina. 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. In high-security offices, a retina scanner is the most common method of scanning. A persons voice can be easily recorded and used for unauthorised PC or network. Advantages: The retina contains multiple layers of sensory tissue and millions of photoreceptors. Ravi Das is a Cybersecurity Consultant and Business Development Specialist. During surgery, CT scans are used to determine the size and shape of the organs and tissues, as well as monitor patients. Copyright 2021 by JojoCms. Considerable size. The following table compares some of the biometric systems used lately, from the point of view of accuracy, cost, devices required and social acceptability. Iris is the visible ring on the front side of the eye that surrounds the pupil of ones eye. Measurement accuracy can also be affected by severe astigmatism. Hacking is an undying cyber theft, which means that hackers can easily manipulate stolen biometric data to create fake positives. a. 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. No direct physical contact is required between the person and the camera, making iris recognition completely non-intrusive. Thus, as a result, if the process is not done correctly, it can lead to a very large False Rejection Rate (this occurs when a legitimate individual is improperly denied access to either physical or logical based resources by the Retinal Recognition System). A single OCT machine can cost anywhere from $35,000 to more than $100,000, but used or refurbished units are significantly less expensive. f. It is standardized. Iris patterns are more robust than voices. . M2SYS Blog holds all the rights to add, remove, modify content in this blog. The fiber-optical coherence tomography procedure improves resolution by using a small fiber-optic light to illuminate the retina. b. Ophthalmologists Leonard Flom and Arin Safir first noted the distinctive features of iris and described methods for iris recognition in 1987. As mentioned earlier, the acceptance of Retinal Recognition by the general public is extremely low. 4 Benefits of Retinal Imaging - IRIS He also does Cybersecurity Consulting through his private practice, RaviDas Tech, Inc. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. When a new authentication system is implanted, it is essential a judgement between simplicity, price and efficiency, as well as social acceptability. Extremely intrusive. It was discovered through his work that even identical twins have a very distinct and unique set of Retinas. The password method is the cheapest and simplest technology, because it only requires elementary software resources. The system makes the authentication process quick and easy; however, it has other advantages, that are: 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. The manual process would be time-consuming; however, the biometric system eliminates the need for physical attendance. Advantages of the Iris for Identification. The result might be affected due to pupil size change. Very high accuracy. The technology, however, has notable disadvantages including difficult image acquisition and limited user applications. If the distance is greater than this, then the scanning process must be repeated over again until it is correct. a. Advantages: Ease of use. Has The Popularity of Technology Created More Money Making Opportunities? Advantages: Ultimately, biometric authentication techniques are all about security. However, there is a negative public perception regarding retinal scanning due to its intrusive nature. This has led to debate about whether the retina scanner should be a commercial or open source technology. 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 biometric system allows them to limit access to unauthorized personnel. It has the stigma of consumer's thinking it is potentially harmful to the eye. Over 20 years ago, a company known as Optos introduced optomap ultra-widefield retinal imaging. They later released their paper, suggesting the use of photographs of these blood vessel patterns of the retina to identify people. Most experts believe that infrared rays, both infrared and non-radial, pose no health risks to users of retinovia and intraocular lenses. 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. CT scan machines are now widely used in hospitals and clinics all over the world. Overall, there is a very negative attitude about using Retinal Recognition amongst the public, at least here in the United States. Though it requires special hardware to use, it can be easily integrated into other devices or systems. Iris scan, however, is more practical in real world applications. Patterns in the iris and retina are unique not only for each individual, remains intact throughout life under normal health condition. Iris recognition is one of the fastest biometric modalities for identity verification and authentication on the market. Require specialized devices so that it can be expensive. Even if a retinal scan itself poses no danger to the eye, users sometimes complain of discomfort from the technology during the enrollment process. 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. Difficult to integrate with other systems. It is a great way to monitor your eye health over time and check for any health problems that may arise. Acquiring an image requires proper alignment and positioning. 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.
