    Abstract: A method includes receiving wireless fingerprint data identifying multiple locations within a specified area and, for each location, one or more signal strength values associated with wireless signals received from one or more of multiple wireless transmitters. The wireless fingerprint data is missing signal strength values for one or more transmitters at one or more specific locations. The method also includes generating a training dataset by adding filler signal strength values in place of at least some missing values. The method further includes training a machine learning model using the training dataset. The model is trained to receive a specified location as input and generate predicted signal strength values as outputs. In addition, the method includes using the trained model to generate additional signal strength values. At least some additional signal strength values are to be used in place of at least a portion of the missing values.

    Abstract: A method includes receiving, at an electronic device and from a second electronic device, a second root identifier, wherein the second root identifier is associated with a second profile tree maintained at the second electronic device and determining that a first root identifier does not match the second root identifier, wherein the first root identifier is based on a first profile tree maintained at the electronic device. The method further includes sending, to the second electronic device, the first profile tree, wherein the first profile tree comprises representation of currently maintained user profiles at the electronic device, receiving, from the second electronic device, user profile update information, and updating a subset of the currently maintained user profiles based on the user profile update information.

    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.

    Abstract: An electronic device may be provided to perform collision analysis. The electronic device may be configured to: receive sensor data from an inertial-measuring-unit (IMU) sensor; detect that a collision event has occurred based on the sensor data and detect collision data from the sensor data; input the collision data into a collision classification model that is trained to predict a collision material type and a collision intensity of the collision event; and determine an action to be performed by the electronic device based on the collision material type and the collision intensity of the collision event.

    Abstract: A method executed by a first electronic device (ED1) includes splitting a selected secret for backup into a plurality of N secret shares in a trusted execution environment (TEE) of the ED1. The method includes transferring, via the transceiver over a short-range transmission, the N secret shares to N trustee devices, by transferring each secret share from among the N secret shares to a different trustee device from among the N trustee devices. Each secret share is configured to cause the trustee device to store the secret share in a TEE of a trustee device upon receipt by the trustee device. The method includes receiving, from the trustee device, one of an acknowledgement confirming the transferred secret share is stored in the TEE of the trustee device or an error warning the transferred secret share is not stored in the TEE of the trustee device.

    Abstract: An electronic device includes at least one transceiver, at least one memory, and at least one processor coupled to the at least one transceiver and the at least one memory. The at least one processor is configured to receive, via the at least one transceiver, an AI model in a trusted execution environment (TEE). The at least one processor is also configured to receive an inference request and input data from a source outside the TEE. The at least one processor is further configured to partition a calculation of an inference result between an internal calculation performed by processor resources within the TEE and an external calculation performed by processor resources outside the TEE. In addition, the at least one processor is configured to produce the inference result based on results of the internal calculation and the external calculation.
