TrueCrypt permet de remédier à ce problème avec les Hidden Volume :
The principle is that a TrueCrypt volume is created within another TrueCrypt volume (within the
free space on the volume). Even when the outer volume is mounted, it is impossible to prove
whether there is a hidden volume within it or not, because free space on any TrueCrypt volume is
always filled with random data when the volume is created* and no part of the (dismounted) hidden
volume can be distinguished from random data. Note that TrueCrypt does not modify the file
system (information about free space, etc.) within the outer volume in any way.
The password for the hidden volume must be different from the password for the outer volume. To
the outer volume, (before creating the hidden volume within it) you should copy some sensitivelooking
files that you actually do NOT want to hide. These files will be there for anyone who would
force you to hand over the password. You will reveal only the password for the outer volume, not
for the hidden one. Files that really are sensitive will be stored on the hidden volume.
