Qualcomm ultrasound 3D fingerprint scanner: Finger replacement password just around the day

Qualcomm ultrasound 3D fingerprint scanner: Finger replacement password just around the day

Sound waves are not only applicable to sound, but also very suitable for accepting your fingerprints. Maybe one day it will replace the hard-to-remember password.

You can't even imagine recording your fingerprints.

At present, your secure fingerprint scan is only available when your skin is in good condition. The reader may not be able to accurately retrieve your fingerprints if your fingers are overheated or too cold and slide by lotion or sweat.

However, Qualcomm's Snapdragon Sense ID 3D fingerprint scanning technology launched at Mobile World Congress solves this problem. It uses ultrasound to capture users' fingerprints-which can be captured successfully in almost all situations.

Enhanced security of 3D fingerprints

Qualcomm's fingerprint scanner uses high-frequency ultrasound to penetrate the dermis layer of the skin to extract your unique fingerprint features, including fingerprint spine, and even-thrilling-sweat pores.

Because the sound can penetrate dirt such as sweat stains, your daily activities will not affect the extraction of perfect fingerprints. In fact, Qualcomm said that the crystallization of your daily activities can also improve the scanning results, making it a more reliable method than the existing capacitive pressing technology.

Another advantage of acoustic fingerprint extraction technology is that it scans deep skin, which means that fake fingerprints made of wood glue or glued from other planes cannot cheat it.

Another additional benefit is that sound waves can scan your fingerprints directly on the device screen, no need to configure a dedicated touchpad or integrate it into the home page buttons (not to mention that not all devices have this button ). It can also penetrate metal, sapphire mirrors (High Wear-resistant glass) and most plastics for scanning.

Replace password with fingerprint

Qualcomm sees this technology, which relies on the Snapdragon processor, as an opportunity to go beyond Apple payments and other similar systems in biometric identification login and authentication.

Imagine you can use near-field communication (NFC) without having to show your medical insurance card or fill out a bunch of forms in the doctor's office) it's amazing to transfer all the required information to the hospital system!

This is only one of multiple use cases, such as replacing passwords, logging on to the system remotely, and purchasing products and services.

To placate cautious security experts, Qualcomm's Yunlong Sensor ID 3D fingerprint scanning technology complies with the online fast authentication (FIDO) protocol. To ensure that fingerprints are at least as secure as passwords, scanning data will not leave the device. Even if others are hacked into the server, your fingerprints are still safe.

Qualcomm has set up two demos to show the working situation of sonic fingerprint scanning to The experiencer.

In the first demonstration, the two mobile phones were placed side by side in a box. The experiencer places his finger in the scan area of one of the mobile phones (black bars under the navigation key ). On the screen next to a mobile phone, an enlarged version of the user's fingerprint is displayed, and the fingerprint spine is invisible.

The right screen displays the fingerprint spine captured on the left screen.

The second demonstration shows the doctor's office use case. Use a fingerprint to log on to the app. Perform secondary verification on the fingerprint to share the patient data in your device with the hospital, such as the address and birthday. Put the mobile phone on the near-field communication transmitter to complete the transmission, and the data on the mobile phone can appear in the "hospital" tablet computer.

NFC can directly transmit the experience data to the doctor's office.
