The iris of the eye has been described as the ideal part of the human body for biometric identification for several reasons:
It is an internal organ that is well protected against damage and wear by a highly transparent and sensitive membrane (the cornea). This distinguishes it from fingerprints, which can be difficult to recognize after years of certain types of manual labor. The iris is mostly flat, and its geometric configuration is only controlled by two complementary muscles (the sphincter pupillae and dilator pupillae) that control the diameter of the pupil. This makes the iris shape far more predictable than, for instance, that of the face.
The iris has a fine texture thatÂ—like fingerprintsÂ—is determined randomly during embryonic gestation. Like the fingerprint, it is very hard (if not impossible) to prove that the iris is unique. However, there are so many factors that go into the formation of these textures (the iris and fingerprint) that the chance of false matches for either is extremely low. Even genetically identical individuals (and the left and right eyes of the same individual) have completely independent iris textures. An iris scan is similar to taking a photograph and can be performed from about 10 cm to a few meters away. There is no need for the person being identified to touch any equipment that has recently been touched by a stranger, thereby eliminating an objection that has been raised in some cultures against fingerprint scanners, where a finger has to touch a surface, or retinal scanning, where the eye must be brought very close to an eyepiece (like looking into a microscope).
The commercially deployed iris-recognition algorithm, John Daugman's IrisCode, has an unprecedented false match rate (better than 10−11 if a Hamming distance threshold of 0.26 is used, meaning that up to 26% of the bits in two IrisCodes are allowed to disagree due to imaging noise, reflections, etc., while still declaring them to be a match). While there are some medical and surgical procedures that can affect the colour and overall shape of the iris, the fine texture remains remarkably stable over many decades. Some iris identifications have succeeded over a period of about 30 years.
Iris recognition works with clear contact lenses, eyeglasses, and non-mirrored sunglasses.
The phone has pretty cool spec but u still lacks in os personalisations .It still uses the same menu type like in previous Nokia Lumia (feel so much outdated).Of course the phone will be having a lot of update which will make the device reach heights .As compared to specs ,I think it is best device in the market .
monty.monty, 11 Oct 2015Yeah design is inspired by a beautiful brickzzzzz monty your boring me
I like the overall package by Microsoft. It makes me want to buy devices for each category and just use 1 account for everything.
Good luck Microsoft and hope it will be a success. I am only disappointed with the design of Lumia 950 (honestly, I like 930's design better..haha).
comeforit, 08 Oct 2015design is totally different, and not ugly actually. i prefer it to be gold series if i wanna buy.Yeah design is inspired by a beautiful brick

It's a Best Phone Ever, Don't go with others, Just go with my opinion. If you purchase this phone it means you have the best phone in your hands. Employment News
Philly, 07 Oct 2015Well seemed like no one in here had tried CHERRYMOBILE phone It would slam all your devices. ... moreCherry what the %@#@???? Lmaol!!!!! Dude I don't know if you are being sarcastic or totally retarded.. Either way... "Keep off the GRASS!!!"
