Facial recognition is typically a quicker security verification than other methods like retina scan. It's also more sanitary, since you don't have to touch anything for a face scan. Pros and Cons of Facial Recognitionįacial recognition make signing into your iPhone as simple as looking at the screen, plus it makes categorizing your Google Photos way quicker than doing it by hand. A face scan is a type of biometric security that uses mathmatical patterns of the face to store that person's unique face identity. Most people who have Googe Photos and/or a newer iPhone already know that facial recognition is not an imaginary thing of science fiction movies - it's real and it's being used every day. For this reason, a retinal scan is considered invasive, while an iris scan is not, and more people are willing to submit to an iris scan than to a retinal scan. ![]() While a retinal scan requires a person to put their eye up to an eye piece for about thirty seconds, an iris scan only requires a quick snapshot of the eye and does not require a person to put their eye up to any eyepiece whatsoever. The most important difference between a retinal scan and an iris scan is probably the convenience and the non-invasive process of the iris scan. There are, however, some differences in the functionality of each type of scan. Both the iris and the retina have unique patterns that are different even in identical twins. Quite simply, both a retinal scanner and an iris scanner take rapid photos of the eye, but a retinal scanner takes photos of the retina while an iris scanner takes photos of the iris. Difference Between a Retinal Scan and an Iris Scan Of course, your laptop could still be stolen, but without access via your unique iris, the criminal will be hard-pressed to access what's on the laptop. There is a device that can connect to a laptop via USB that uses a wand to scan the iris. Outside of certain moblie phones and government/business security, iris scanning isn't used a lot. ![]() Right now, iris scanners are used for people to access certain devices such as mobile phones, border defense and a national citizen ID program, as well as gaining access to organizations. However, they are designed to not scan for more than 10 seconds or scan if you are too close. It's a common misconception that iris scans can be damaging to your health. Some they believe that if there is a national database of people's irises, people could be tracked without their knowledge. Iris recognition could have a major con, however, because of a potential security risk. Another pro is that it is more sanitary since no physical contact is required, as the iris can be captured from a distance. For this reason, it's hard to hack this type of security recognition. Iris scan recognition is extremely accurate, since everyone's irises are unique and don't change as people age. Like the retina, each person's iris is unique and has patterns that set them apart. The iris lets light into the eye and controls the pupil. The iris is the colored portion of a person's eye, with the pupil in the center. An eye doctor or specialist will also use a retina scan to test the health of the eye, checking for issues such as diabetic retinopathy, glaucoma, age macular degeneration, and detached retina.Īn iris scan uses infrared light to looking at the unique pattern's in a person's irises in order to confirm a person's identity. That's why retina scan devices can be used for military, corrections, high-level government, and similar security clearances. How is Retinal Scanning Used?īecause of its expense, you may not see these often, however they are very useful when a high level of security is needed. Some also believe it poses a health risk to the person being scanned. Because of its advanced technology, a retina scanner is typically quite expensive. It's hard to hack this type of security scan, which is a good thing. Retina security scans are very accurate and secure, as it looks at unique patterns of a person's retinas and records them on video. A retina scanner uses low-intensity light to look at the unique patterns on the blood vessels of the retina to certify who a person is. Like a fingerprint, each person' retinas are different and are the same throughout their lives. A retina is the layer at the back of the eyeball. A retina scan is a way of securely verifying a person's identity. ![]()
