Ultrasound reads deep into your fingerprint
Sense ID is so inconspicuous that it isn’t visible at all. Qualcomm’s found a way to hide the ultrasound sensor in any of the most commonly used materials in smartphone design: aluminum, glass, and plastic. That means there’s no need for a Home button or even a bezel — manufacturers could simply embed an ultrasound sensor in the middle of the screen underneath the glass, on on the back beneath the plastic or metal casing.
Since the ultrasound detects deep into your skin, it can actually sense whether the fingerprint in use is attached to a living person.
Since the ultrasound detects deep into your skin, it can actually sense whether the fingerprint in use is attached to a living person. The technology detects the motion of blood flow under your skin, alerting the software that the fingerprint is indeed real and a part of a living person. Neither glue molds nor hacked-off thumbs from gangster movies can fool Qualcomm’s Sense ID. To top it all off, the sensor isn’t bothered by sweaty hands, lotion, or lightly wet fingers. It’s readings are deep enough to see beyond all that superficial stuff.
There’s a lot of security and technology behind it
To make its technology more readily available, Qualcomm’s partnered with the FIDO Alliance and the IBIA (International Biometric Industry Association). Although Sense ID uses Qualcomm’s own special technology — of course — it owes the ultrasonic technology to Nok Nok Labs’ S3 Authentication Suite.
Sense ID will theoretically be used to open your smartphone, make payments, log into apps, and essentially eliminate passwords. Worried about where that fingerprint data may go? Yeah, we are too. But Qualcomm assured us that it’s stored locally on the Snapdragon 810 processor in a special, dedicated space that’s heavily secured. Sense ID 3D Fingerprint Technology (that’s its full name) includes the Qualcomm biometric integrated circuit (QBIC), sensor tech, and algorithms controlled by SecureMSM.
Sense ID is coming to phones soon
Although it will work only on devices using the Snapdragon 810 processor at first, it will also work with the upcoming 425 processor, and later, the Snapdragon 400 series, 600 series, and 800 series of chips. Luckily, Sense ID isn’t one of those ethereal, Qualcomm pipe dreams — it’s actually coming to a smartphone near you, and soon! Qualcomm Snapdragon Sense ID 3D Fingerprint Technology should arrive on devices in the second half of 2015. The company’s already sampling it out to manufacturers, and some big names have committed to using it.
There’s no word on who those bigwigs are or how much the technology will jack up the price of phones, so we’ll have to wait it out a bit longer. We’ll keep you updated.
