Only a month ago, Apple released its premium handset iPhone 5S with finger-print scanner. Now, the brand's arch-rival Samsung is reportedly going an extra mile by trying to accommodate a more sophisticated eye-scanning technology in its upcoming Galaxy S4 successor.

Technology blog, AndroidSaS citing sources in Korea has claimed that the reigning smartphone leader has already started working on the eye-scanning sensors, which is expected to be used as an additional security measure to unlock the Galaxy S5 screen.

Even though finger-print scanner is relatively new to the smartphone industry, Eye-ball scanning technology will be a giant leap in the handset business as it is more evolved and secured than the former, which can be forged using fake thumb prints. Recently, Apple iPhone 5S's marquee feature Touch ID system was cracked within few days of its release by a group of German hackers, CCC (Chaos Computer Club) using semi-transparent latex mold.

On the other hand, Eye-scanning aka 'Iris Recognition' involves camera technology with subtle infrared illuminations to capture detailed nerve pattern on the iris. Using this data, digital templates are created by mathematical and statistical algorithm so that accurate profile is created.This biometric technology is nearly impossible to crack by any imposters; it is currently by used by many countries for identification purposes in passports for air travelling; even India government owned UIDAI (Unique Identification Authority of India) is using Iris recognition technology in the on-going national ID enrolment scheme, Aadhaar.

Though Samsung has not yet confirmed the rumours of the eye-ball scanning technology, it has said on record that the company's forth coming Galaxy S4 successor would come with 64-bit architecture based chipset.

The upcoming Galaxy S5 is speculated to come with a premium look, featuring metal body case and is likely to run on Android Kit Kat v4.4 OS powered by Exynos 6 (64-bit) Octa-core processor and house 16.0-megapixel OIS (Optical Image Stabilization).
