ABSTRACT:
Seismic survey data is stored in encrypted format in a first memory. The first memory module is transferred to a first computer in a first location. A portion of the seismic survey data is selected using a second computer in the first location, wherein the second computer communicates with a second location. A request authorization is transmitted from the second computer to the second location. A decryption code is transmitted from the second location to the second computer. The decryption code is transferred from the second computer to the first computer. The decryption code is applied to the selected portion of seismic survey data in the first computer, making available seismic survey data in decrypted format.
