Abstract
A method and system for verifying a client device's location in a parallel reality game hosted by a server. The client transmits its location to the server and receives verification instructions comprising a landmark and a verification pathway. The client prompts a player to capture image data of the landmark and, in response, receives a first set of image data of the landmark from an initial perspective. The client determines whether the first set of image data matches to the landmark before prompting the player to move along the verification pathway while capturing image data. The client receives a second set of image data of the landmark from a moving perspective. The client determines whether the second set of image data matches to an expected change in perspective of the landmark. Upon completion of the verification instructions, the client confirms to the server the client's location.
