The encryption of seismic data is completed by randomly rotating and shifting survey coordinates.

Step 1

As shown in Fig.1-7-1, select the menu "SEGY->Encrypt SEGY", we get the dialog as Fig.1-7-2.

Step 2

Click "Add" to select the file "vib_eg.sgy" as shown in Fig.1-7-3 and click "OK" to start the job, from which the job information is output as in Fig.1-7-4.

Step 3

As Fig.1-7-5, select the menu "SEGY->Browse SEGY Header" and open a dialog(Fig.1-7-6), select the raw SEGY file "D:/vib_eg/vib_eg.sgy" to show its header data in the table as Fig.1-7-7.

Step 4

Select the SEGY file "D:/vib_eg/vib_eg_Encrypted.sgy"(Fig.1-7-8) to show its headers(Fig.1-7-9), from which we can see that the coordinates have been changed.
