A processing apparatus including one or more processors and memory determines a first context of a first user at a first location in a physical space based on sensor measurements from one or more sensors of a set of one or more devices coupled to the first user and detects movement of the first user to a second location in the physical space based on sensor measurements from one or more sensors of the devices. The processing apparatus determines a second context of the first user at the second location based on sensor measurements from one or more sensors of the devices and generates, based on the first context, the second context, and the movement of the user from the first location to the second location, a first mapping of the physical space that includes information corresponding to a spatial relationship between the first context and the second context.

Determining a spatial relationship between different user contexts

Method and systems for modeling user possession of a mobile device for a user authentication framework are provided. The method includes analyzing sensor data representing information captured from sensor(s) associated with at least one of a plurality of devices, the plurality including the user's mobile device. The method allows for determining, based on the analyzed sensor data, a probability that the user maintains possession of the user's mobile device; and configuring the probability for use in determining whether to require authentication. The determination may include configuring a probabilistic model that includes a first state indicating that the user possesses the mobile device and a second state indicating that the user does not; classifying motions of the mobile device by types, the motions being determined based on the sensor data; and updating probabilities of the two states in response to determining that at least one of the motions has occurred.

Method for modeling user possession of mobile device for user authentication framework

A processing apparatus including one or more processors and memory obtains one or more sensor measurements generated by one or more monitoring sensors of one or more devices, including one or more monitoring sensor measurements from a respective monitoring sensor of a respective device and obtains one or more system signals including a respective system signal corresponding to current operation of the respective device. The processing apparatus determines device context information for the respective device based on the one or more sensor measurements and the one or more system signals and adjusts operation of the device in accordance with the device context information.

Combining monitoring sensor measurements and system signals to determine device context

A computer system stores calibration information corresponding to respective sets of sensor measurements associated with respective operating environments. After storing, in a first data structure, calibration information for a first operating environment, the system determines a current operating environment of the device. When the current operating environment of the device is consistent with the first operating environment and the calibration information for the first operating environment meets predefined measurement diversity criteria, the system calibrates at least one sensor for the first operating environment using the stored calibration information for the first operating environment. When the current operating environment of the device is inconsistent with the first operating environment, the system excludes the stored calibration information for the first operating environment when calibrating one or more sensors for the current operating environment.
