Smartphone seguridad hindi na may sa maging isang mga gawaing-bahay salamat sa epektibong biometrics na gawin ang kanilang mga trabaho at makakuha ng out sa iyong paraan walang pag-kompromiso ang iyong data

Tandaan kapag ang iyong telepono unang nagkaroon ng camera? Ako ay maganda, sigurado, ngunit ito kinuha basura mga larawan at bihira mo ginagamit ito. Pagkatapos ito nakuha ng isang capacitive touchscreen, na kung saan ay mas mahusay kaysa sa paggamit ng pluma, kahit na hindi mo maaaring i-type pati na rin ang paggamit ng isang keyboard. Mabilis parehong pinabuting at naging mahahalaga.
Pagkatapos ay dumating ang fingerprint sensor, at naisip mo: talaga? Bakit? Paglalagay sa isang pin ay hindi na masakit, ako tunay mangilangan ito? Ngunit ngayon ikaw ay hindi kahit na isipin ang tungkol sa sensor fingerprint, o lahat ng mga segundo na-save mo, dahil ginagamit mo ito sa lahat ng oras. 2015 ay ang taon fingerprint scanners dumating ng edad.
Ilang taon na ang nakalipas, to unlock your phone was a multi-tap affair – using a long pin or password – every time your screen went dark. It was so tedious that many just didn’t bother, leaving the handset and everything on it, vulnerable to a passing criminal. Or just to a friend who thought sending dirty texts to your mum from your phone showed a ‘sense of humour’.
Fingerprint scanners have come to save us from the endless unlocking nightmare, and those awkward conversations with our mothers, while keeping our phones secure. But we shouldn’t be surprised they’re proving so useful.
Fingerprints have been in use for identification purposes as early as 1858, as a way of verifying signatures on contracts. Since then the patterns of skin ridges have been a simple and effective method of identifying someone with an 98.6% accuracy for a single finger, according to data from the US National Institute of Standards and Technology.
Consumer fingerprint scanners have been around for the last 10 taon, normally equipped to computers as a security device. But scanners that force the user to swipe their finger across a sensor proved to be slow and not accurate enough to recognise a user 100% of the time on the first go.
They were gimmicks. Something to sell a smartphone or computer that didn’t add real value to the lives of most users. They just added frustration rather than reducing it.
Apple’s Touch ID, a touch-based fingerprint sensor embedded under the 2013 iPhone 5S’s home button, was the first to be introduced with technology good enough to reliably identify an owner. It was was faster than entering a pin and you didn’t need to swipe, just place a finger on the home button for a second or so.
Dahil sa 2013 fingerprint sensors have improved and diversified. Last year saw serious rivals from Samsung at Huawei. Ngayong taon, almost every flagship phone launched with a good fingerprint sensor, while even some mid-range and lower-cost devices came equipped with them.
Today they appear on the front andback of the device and even under the power button on the side in Sony’s case. They generally recognise fingerprints with around a 98% accuracy and in under one second, which makes them power-on and unlock with one touch. No gimmicks, just a piece of security seamlessly integrated into the modern smartphone experience.
Apple set the goal posts, but the majority of Android users have two little known firms to thank for this easy of use upgrade: the Swedish companies Fingerprint Cards AB and Precise Biometrics, one of which makes the hardware and the other the software.
In the case of Android and iOS, fingerprints are stored locally and not sent away to a server – an important security step as, unlike a password or username, you cannot change your fingerprint if it is stolen.
Once you have used a good fingerprint sensor, it’s surprisingly difficult to go back to having to tap in a pin or swipe a pattern to unlock your phone. And that is just the start. Most smartphones with fingerprint sensors also allow users to secure other parts of the phone with their digits, effectively alleviating the problem of trying to remember or enter a long, secure password for making app purchases, halimbawa.
If you’re launching a smartphone in 2016 without a fingerprint sensor, you might as well be leaving out the selfie camera and the touch screen too.
The immediate next step for fingerprint scanners is likely to be on-screen scanning. No button, no sensor, just a touchscreen that recognises who’s touching it. Science-fiction movies have been trying to show how it works for years, whether it ever will remains to be seen.
And fingerprints are just the start of the promised biometric surge into technology. Iris scanners, hand-vein scanners, heart rhythm monitoring and various other relatively unique aspects of the human body are all contenders to be the next big thing.
