Disclosed is a system and a method for authenticating the location of a user's smartphone using a central server to a third party. The method and the system is a secure way to calculate the GPS location on a centralized server which is operating the Time and Place Decryption software that has one of its inputs being a Smartphone transmitted encrypted prevailing code string which contains the original GPS coordinated representing the location and the Atomic time at which the encryption took place, as well as a combination of all or some other Knowledge, Ownership or Inheritance identification factors or tokens—FaktokIns. The more FaktokIns that are used in the encryption the harder it is to fake or replicate the GPSTOTP.
