US Patent 9882996 Determining data associated with proximate computing devices

A computing system is described that determines a location of a first computing device at a particular time. Responsive to determining that a second computing device is located within a threshold distance of the location of the first computing device at the particular time, the computing system identifies, based on contextual information associated with a user of the first computing device and contextual information associated with a user of the second computing device, at least one data file that the user of the first computing device is likely to access at the particular time. The computing system then outputs, for transmission to the first computing device, an indication of the at least one data file.
