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 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.

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: 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.
