Huawei recently released a patent to use lip movement to unlock devices.
According to data technology service company, Tianyancha, Huawei unveiled a "device unlocking method and equipment" patent on Tuesday, which the company said can use the biological attributes of lip movement for identity authentication, thereby unlocking devices.
The technology has more flexibility, anti-plagiarism and modifiability features, according to the patent description.
Like the face unlocking application that has been installed in many mobile devices, lip unlocking records the original movements from the owner's lips to unlock the device .
The new technology became a trending topic on China's Twitter-like social media Sina Weibo, where many applauded it as a novel innovation. However, others also expressed concerns about the practicality of the technology during the COVID-19 pandemic where people are still advised to wear masks in most places.
