Privacy-based device location proximity
Abstract:
A server may receive a query from a query device. The query may include an identifier that identifies a user device, information regarding a geographic radius, and information regarding a geographic position. The server may determine a first proximity area based on the geographic radius and the geographic position indicated by the query. The server may determine a second proximity area that represents an area in which the user device may be included. The server may determine a value that indicates a likelihood that the first proximity area is within the second proximity area. The server may provide information to the query device indicating the value.
