Location Based Trust

Location Based Trust (patents pending) is a term coined by Professor Orest Pilskalns and first used publicly at the "Building A Better Journalist" seminar on October 24, 2009. The term is related to auto-geotagging where information is associated with a location and published on the internet in real time. Trust is generated when applications enforce associating a location with information by using the GPS sensor in the device where the information was generated or captured.
Commercial Application
Often content is associated with a location, with no guarantee that the author of the content has actually visited the location before creating the content. By enforcing a system that requires the user to publish content about a location, from the location, a new level of trust is created with the consumers of the information. This will require the authors to use some sort of device capable of auto-geotagging to publish information at the location concerning the information. For example, if you are writing a review about a restaurant, you actually have to be at the restaurant to publish the information.
Abusing Location Based Trust
If one can spoof their location by sending false location data, then the location based trust is broken. This can be prevented by creating . Location based signatures also coined by Orest Pilskalns is the ability to associate a digital signature with a location based on unique environmental data collected by communication sensors on the device where the user publishes data. By comparing unique environmental data with previous data submitted from a remote location, location based trust applications can differentiate between spoofed locations and actual locations.
