Patent number: 11861247Abstract: This application relates to the field of mobile communications, and in particular, to a technical solution of sharing data with a nearby device by using a wireless communications technology. In a method for printing a photo, a mobile phone first selects a to-be-printed photo, then discovers a nearby device by using the foregoing related wireless communications technology, and displays the discovered device such as a printer or a projector on the mobile phone; and then a user performs a tap operation on the discovered printer, so that one-tap printing can be implemented. In this way, printing efficiency of an electronic device is improved, and user experience is also improved.Type: GrantFiled: October 20, 2022Date of Patent: January 2, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Changzhu Li, Jiaxin Li, Xiaodong Tian, Yu Tang

Patent number: 11461447Abstract: A device and method providing audio-based, continuous authentication of a user to provide access to a processing device. A user echoprint model is created while a user interacts with an authentication interface for another authentication method of the device, transparently to the user. The sound waves are user-specific and inaudible. The user-specific sounds are reflected by the user and used to construct an echoprint which can be compared by a previously constructed user-specific, echoprint model. If the result is positive, access to the processing device may be allowed. Access to the processing device is based on the audio authentication or the alternative authentication is based on the result of audio authentication and updates a device state indicating whether the display is on or off and whether the device is locked or unlocked.Type: GrantFiled: November 25, 2020Date of Patent: October 4, 2022Assignee: Futurewei Technologies, Inc.Inventors: Changzhu Li, Shuang Wu
