Abstract :
This contribution proposes a service that provides location information of a GSM mobile device that can be mapped to a specific user and can be verified by means of asymmetric cryptography. The service returns a digitally signed record - a location stamp - that can be used as a proof, eg, in commercial transactions using mobile telephones
