Qualcomm announces new 3D Fingerprint sensor technology during MWC 2015; The company calls it “Sense ID”. A lot of people asking us, will it surpass the current generation biometric technology, which is being used by Apple, Samsung and other smartphone makers? So we are here to let you know how the Sense ID works and how it competes with current gen technology.
Technology behind it:
Qualcomm uses entirely different technology to implement biometric sensors for next-generation smartphones; It is officially referred as “Sense ID 3D Fingerprint” technology. Instead of using traditional 2D flat axis technology found in Apple and Samsung devices, Qualcomm implemented a new way to scan our fingerprints. The latest technology takes the 3D photo print of your fingerprint using ultrasonic waves. Surprisingly, it can even recognize whether or not the fingerprint in use is attached to a living person. Additionally, the ultrasonic wave can pass through multiple surfaces. Theoretically, it should work through Glass, Plastic, Metal even through Sapphire glass. Also, it can work with wet hands. However, it is true that the thickness of the surface will decrease the strength of sensor’s reading capacity.
How it embedded into Qualcomm chip:
Qualcomm is very much concerned about the security and accuracy of the Sense ID. The fingerprint data stores natively on SoC, but Qualcomm has given a dedicated place to store your data that will be highly secured. Furthermore, the data will be encrypted using most advanced algorithms and only accessible when the user needs it. I would say, Qualcomm has done serious work in collaboration with FIDO Alliance and IBIA (International Biometric Association) to make sure everything is highly secured. To let you know, Qualcomm is using ultrasound technology, which is originally developed by Nok Nok Labs S3 Authentication Suite. Meanwhile, the Qualcomm biometric integrated circuit (QBIC), sensor tech, and algorithms controlled by SecureMSM.
How is it useful to end users?
Sense ID can be helpful to avoid typing and remembering the password/passcodes. Users can just place their finger on the area where a sensor has embedded, and that’s it. The phone will securely unlock. You will need to say goodbye to the dedicated fingerprint sensors at a point in future. Furthermore, it will allow users to make payments and log into apps without typing passwords. Currently, Qualcomm is shipping its Snapdragon 810 chips with Sense ID. In future, Snapdragon 425 and newer 400 series and 600 series chips will also sport with this technology.
How is Sense ID different from current biometrics?
Current generation biometrics from Apple and Samsung uses 2D technology to take fingerprints as we discussed earlier. With this technology, users have to place their finger at a particular location to get read their pre-assigned fingerprints but with Sense ID, OEMs can embed the sensor at anywhere on the device. No matter if the OEM decides to put it on side bezels, underneath the display or home button/power button, it will work seamlessly since Ultrasonic waves can pass through any of the surfaces. Just like the Sci-fi movies, users can unlock their devices and make payments by placing a finger on the display.
I think, you guys are now familiar with Sense ID and how it works. I would say, it is the best biometric technology i have ever seen. It is super easy to implement and flexible enough to position and accurate while reading your fingerprint. We are going to see future devices with Qualcomm’s Sense ID.
