  • Publication number: 20210150009
    Abstract: 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.

  • Patent number: 11013040
    Abstract: Embodiments are provided for identifying transitory WiFi users and providing a differential treatment of such users in terms of delaying associating steps between user stations (STAs) and an access point (AP). A transitory user refers to a user or user device that connects to a WiFi AP but does not run applications that require association or assigning IP addresses, such as short-term or temporary connected WiFi users that are on the move. In an embodiment, a STA connects to an AP. Upon the STA indicating its transitory behavior to the AP or the AP detecting criteria of transitory behavior of the STA, the STA obtains a delay time value from the AP. The STA then delays sending an association request to the AP, or alternatively, the AP delays handling the association request from the STA in accordance with the delay time value.
