Abstract
A database for location or geographic based services is secured by requiring location based requests to include a unique identifier that identifies the location as well as an authorization identifier associated with the location. The authorization identifier is information that is obtained by being physically present at the location, such as information from access points that are at the location or a position fix when present at the location. The authorization identifier may be non-unique but relatively time-invariant, making such information easily crowdsourced, but difficult to obtain unless physically present at the location. For example, the authorization identifier may be an SSID or a Beacon Frame, or a hash thereof from one or more devices at the location or a position fix.
