Publication number: 20210150009Abstract: 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: ApplicationFiled: November 25, 2020Publication date: May 20, 2021Applicant: Futurewei Technologies, Inc.Inventors: Changzhu Li, Shuang Wu

Patent number: 10872599Abstract: A device monitors audio data for a predetermined and/or user-defined wakeword. The device detects an error in detecting the wakeword in the audio data, such as a false-positive detection of the wakeword or a false-negative detection of the wakeword. Upon detecting the error, the device updates a model trained to detect the wakeword to create an updated trained model; the updated trained model reduces or eliminates further errors in detecting the wakeword. Data corresponding to the updated trained model may be collected by a server from a plurality of devices and used to create an updated trained model aggregating the data; this updated trained model may be sent to some or all of the devices.Type: GrantFiled: June 28, 2018Date of Patent: December 22, 2020Assignee: Amazon Technologies, Inc.Inventors: Shuang Wu, Thibaud Senechal, Gengshen Fu, Shiv Naga Prasad Vitaladevuni
