A method to improve data access control, the method comprising: assigning at least one threshold to at least one contextual criterion; receiving, by a receiver associated with a claimant, at least one secure geographically dependent spot beam based signal; receiving contextual information from the claimant; determining whether the contextual information from the claimant meets the at least one threshold to the at least one contextual criterion; authenticating the claimant, when the contextual information from the claimant meets at least one of the at least one threshold to the at least one contextual criterion; and allowing the claimant access to data, when the claimant is authenticated, wherein the contextual information from the claimant includes a geographical location of the claimant when the claimant is attempting to access the data, the geographical location of the claimant is determined by using satellite geolocation techniques, and the satellite geolocation techniques use the at least one secure geographically dependent spot beam based signal to obtain the geographical location of the claimant, wherein the at least one secure geographically dependent spot beam based signal depends upon the geographical location of the receiver associated with the claimant.
