There are a number of ways you can open your phone, such as using a PIN number, fingerprint sensor, or two-dimensional face recognition feature that is not secure and can be deceived in a photo.
Sony wants to develop the technology. There are reports that it will be introducing a three-dimensional facial recognition system at the World Mobile Congress this week on Xperia phones. The device will use a built-in 3D sensor from Sony’s SoftKinect and a KeyLemon face recognition system in Switzerland.
Sony claims that the new technology is safer compared to the 2D face recognition system, but the company has yet to announce when the first 3D face recognition device will be released. If Sony succeeds in implementing this idea, it will often be released for the first time on one of the company’s leading phones.
