You might have noticed in those James Bond spy movies – an agent in black walks up to the locked entrance of a high-tech super-secret facility. With a quick eye scan at the terminal, a robotic voice notifies immediately that they have been identified and then, they are allowed to enter. Wasn’t that amazing, right?
While these gadgets in most of the Bond movies seem awesome, they aren’t real. On the contrary, iris scanners exist beyond the realm of fiction.
This reminds us of the recently launched Samsung Galaxy Note 7. Besides having a pool of unique features, it does have an iris scanner, which is pretty cool! It is for this reason that this new Note 7 has created a buzz around.
Iris Scanner is a technology that was once a part of the science fiction movies is now easily accessible to the customers.
Want to learn more about this amazing tech? Let us explore how iris scanners work.
How does Iris Scanners do their Magic?
Have you ever heard of the two different colors of eyes? It’s a fun fact, but a real one. Having eyes of two different colour is a condition called hetero-chromiairidum. It is a rare trait and is found in less than 1% of the world’s population. Among the various eye colors, brown is the most common one, while amber, green, and silver are also the rarest.
Now what’s an iris?
Iris is a beautiful part of the eye that recognizes color of an eye. When you look at your eyes from close, you’ll find intricate, curvy lines on its surface, which span in and out. The pattern these lines form is read by an iris scanner to identify you as YOU. This pattern of lines and waves is very complicated and is generated randomly; it doesn’t change with time. This means that every individual’s eye is unique. You might get shocked but yes it’s true that even your left and right eyes different in their iris pattern.
However, an iris scanner isn’t just used to take pictures of your eye for comparing against whatever it is recording. The actual process is: firstly, a beam of near-infrared light directs at the person’s eye. This near-infrared light works improving than visible light as it exposes the pattern of the iris comparatively more clearly. Hence this makes it easy for the camera to capture it. Apart from this, with this type of light, iris scanner can work in the dark also. Even the colored lenses and prescription glasses do not obstruct the beam. On capturing the image, the iris patterns are translated into code using intelligent software. The resultant code is then searched for an appropriate match.
This is one such technology that Top 10 Android app development companies can use to develop unique photo apps.
What makes the Galaxy Note 7 Iris Scanner Unique?
While the iris scanner in Note 7 works the same as described above to a great extent, there are definitely other reasons that make special. Note 7 phone has a separate dedicated front camera designed solely for taking iris readings. This front cam is supported by an LED shooting near-infrared light at the customer’s face.
One question that arises here is that why iris scanning can’t be performed by the front-facing camera? This is because the camera that undertakes iris scanning requires high sensitivity for the near-infrared beam of light. On the other hand, in the traditional cameras, the IR beam is filtered due to its interfering with the standard photographs. Also, the scanning camera has a finer angle of view to “see” the user’s eyes better, particularly at a distance.
While Samsung is not the only company to come up with an iris scanner phone, it could become the first to launch a smartphone with an iris scanner that is actually very good.
