This Is How Apple’s Fingerprint Sensor Could Work
Biometrics is nothing new and every day we see it incorporated into our lives that we hardly take notice of the convenience it offered us compared to the tiresome processes we used to endure way back when.
For instance, when you go to work today, you don’t “punch in” your time card (what’s that?) like they used to, instead you probably swiped an ID, looked into a cam or pressed your finger/hand onto a biometric scanner which you did quite instinctively and naturally and in you go.
Nothing to it, really…
So it’s also quite natural for forward looking companies like Apple to integrate this biometric technology further into our daily lives by incorporating it into its products, particularly iDevices, which have become an essential part of our existence.
A couple of days ago, we talked about how Apple’s rumored iPhone 5S will definitely have some sort of fingerprint sensor built into it and how Apple and Apple-owned AuthenTec filed a patent for mass producing these fingerprint sensors, which had been a manufacturing conundrum in the past, until now, that is – and today, this latest report from our dear friends @ 9to5mac tries to enlighten us mere mortals to this touch technology we call biometrics.
The article featured the in depth knowledge shared by Geppy Parziale, InvasiveCode’s in house biometrics authentication expert, and I tell you, it’s a very interesting read, to say the least. Really gives you a good idea how biometrics play an ever-increasing role in our daily life.
From Geppy Parziale (via invasivecode):
There are 2 kinds of fingerprint capture methods: touchless and touch-based fingerprint capture. I pioneered the first category. This capture technique requires a camera with very sophisticated optical lenses and a complex lighting system. The huge advantage of the touchless fingerprint devices compared to the touch-based ones is that, since the finger does not need to touch any rigid surfaces, the skin does not deform and the image captures very rich details that can make the recognition more accurate. Manufacturing costs are the main issue with this kind of devices and they cannot be miniaturized, so touchless fingerprint devices are not suitable for cellphones.
Yes sir, we do not want something that could cost us an arm and a leg, so it would definitely the touch-based fingerprint capture for us please…
Further from Geppy Parziale:
The touch-based fingerprint sensors require the user to touch a rigid surface (the platen). During the touch, the fingerprint can be acquired with different technologies. However, during the touch, the skin deforms making these devices less accurate than the touchless ones…Finally, we get to IC or CMOS (Complementary Metal Oxide Semiconductor) fingerprint devices. They are made in Silicon in a very similar way to a chip or any other integrated electronic circuit. They can be very thin and very small and, their production costs make them very attractive for mobile applications so they seem like the right candidate to be embedded in an iPhone. And indeed, you should expect this kind of sensor in your next iOS device.
So you see folks, even the expert agree that Apple really has something going on with this biometric fingerprint sensor thingy and who am I to argue with that kind of endorsement?
Thing is we’ve all been waiting for something new from Apple and this fingerprint scanning sensor might just be the Apple’s ticket back into the limelight.
What do you think?
Keeping you in touch with anything and everything Apple.
Making it personal, always.
