    Abstract: A method of providing continuous user authentication for resource access control includes launching a continuous authentication service at a boot time of a first device, wherein the first device includes a processor, a memory, and one or more sensors configured to collect authentication information. Additionally, the method includes receiving authentication information comprising one or more of explicit authentication information or implicit authentication information, and receiving a request for access to a resource of the first device. Further, the method includes the operations of determining, by the continuous authentication service, a current value of a security state, the current value of the security state based in part on a time interval between a receipt time of the authentication information and a current time and controlling access to the resource based on the current value of the security state.

    Abstract: A method includes emitting a sound by a first device. The method also includes receiving a recorded sound at the first device, where the recorded sound includes a recording of the emitted sound by a second device. The method further includes determining an intermediate frequency (IF) signal based on the emitted sound and the recorded sound. The method also includes determining a distance between the first device and the second device based on a frequency of the IF signal and one or more characteristics of the emitted sound. In addition, the method includes presenting the determined distance.

    Abstract: An apparatus includes a display, a processor coupled to the display and a memory coupled to the processor, wherein the memory includes instructions executable by the processor to identify an access attempt to a monitored resource by an application, the identification occurring after an access permission check is performed. The memory further includes instructions executable by the processor to determine whether the access attempt involves suspicious activity by evaluating a potential risk associated with the application accessing the monitored resource, and in response to determining that the access attempt involves suspicious activity to provide a graphical user interface (GUI) to the display, the GUI providing a notification of the access attempt.

    CPC classification number: G06F21/6245 G06N20/00

    Abstract: A method includes obtaining, by an application executing on a processor of an electronic device, user data of a user, generating a representation of the user data, applying local differential privacy to the representation of the user data, to generate a transform of the representation of the user data, sending the transform of the representation of the user data, to a service provider via a network and receiving, from the service provider, via the network, service data based on the transform of the user data. The service data includes a user-specific output based on the transform of the user data. The application executes outside of a trusted execution environment (TEE) of the electronic device. The transform of the representation of the user data is generated in the TEE of the electronic device.

    Abstract: A method for detecting a drop event of an electronic device, may include: obtaining an angular velocity and a proper acceleration of the electronic device based on sensor data received from an inertial measurement unit (IMU) sensor of the electronic device; obtaining centripetal acceleration of the electronic device based on the angular velocity, principal moments of inertia of the electronic device, and position of the IMU sensor within the electronic device; based on an acceleration difference between the centripetal acceleration and the proper acceleration, determining whether the electronic device is in a fall state; and based on the electronic device being determined to be in the fall state, providing an analysis result of the drop event.
