Yahoo Pioneers New Biometric Password: Scan Your Ear to Unlock Smartphone

Researchers at Yahoo Labs have figured out how to unlock smartphones by scanning your ear.

The technology is called Bodyprint, according to a blog post on the team’s website, and it uses a smartphone’s capacitive touchscreen to sense and “scan” your ear when you press it against the device, which then generates an image that can be used to identify the user and unlock the phone.

Yahoo Labs has also managed to get Bodyprint to work with other parts of the body including fists, knuckles, fingers, and palms, again using the smartphone’s touchscreen display to create a low-resolution image unique to each user. This could then be used to lock and unlock files.


The most compelling use case for Bodyprint seems to be using your ear to unlock your phone, however, as people already hold their phone at least partially against their ear when talking.

Below you can see what the relatively short authentication process looks like, which requires your full ear to be pressed against the phone’s display before being free to talk.

While most high-end smartphones like the iPhone 6 or the Samsung Galaxy S6 already include fingerprint-scanning technology, Yahoo Labs thinks Bodyprint could be used as a cheaper alternative in smartphones, since no additional sensors are needed since it utilizes the device’s touchscreen instead.


Modern fingerprint sensors have an incredibly high resolution, and while using a smartphone’s touchscreen as a sensor instead leads to a lower-resolution image, the Yahoo Labs team says it’s still plenty accurate.

“Bodyprint compensates for the low input resolution with an increased false rejection rate, but does not compromise on authentication precision,” the team wrote. “In our evaluation with 12 participants, Bodyprint classified body parts with 99.98% accuracy and identifies users with 99.52% accuracy with a false rejection rate of 26.82% to prevent false positives.”

There’s no telling if or when Bodyprint technology will find its way onto cellphones, but it would be an incredibly clever and cost-effective way to bring bio-identification to more cellphones.

“Due to their cost, capacitive fingerprint scanners have been limited to top-of-the-line phones, a result of the required resolution and quality of the sensor,” the team said on its website.

But Bodyprint doesn’t require the same costly sensors. In fact, it just needs a standard touchscreen.

“The surface area [of a touchscreen] is large, allowing the touch sensor to scan users’ body parts, such as ears, fingers, fists and palms by pressing them against the display,” the team said.

During initial trials with 12 participants, Bodyprint classified body parts with 99.98 percent accuracy, and identified users with a 99.52 percent success rate.

The system was most accurate when scanning the ear, due to its more unique size and shape.bodyprint1

Those who share a device with others can even store multiple body prints in a single phone. Users can also require the prints of two users to unlock a particular document within the phone, adding extra security.

The team has not commented on when the system may be available to manufacturers, stating that their next steps include the improvement of recognition algorithms and further testing.

All of this getting us closer and closer to the mark of the beast. Why not use safer passwords?  Do we really need to scan our body parts?  Perps can hack into a phone whether you safeguard it with biotmetric passwords or any other type of password. Anything can be hacked – and this poses even more of a threat because they can steal your identity. So one would really have to ask – are we selling convenience, or gathering intel?
