Cascading fragmentation is a method of providing ultra
high privacy. When making a set of files secure, you select
a level of security. If you select the regular private option, the resulting privacy
protected archive files are the result of blowing to bits
your vulnerable data files, disguising the fragments, and gluing them together in
random ways. If you select the high security option, the process
is repeated anywhere from two to seven times. Your blown-to-bits fragments are gathered up
and blown apart again, and again. One new
reconstitution file is produced for each cascade. If even one of these reconstitution files is kept
back from people trying to get at your
data, they have no hope of making sense of your privacy protected archive files.
Cascading fragmentation is standard when you choose the high
security level. Caution: If you lose one of the reconstitution files, you are in the same position as
the outsider; you will not be
able to get at your data either! Remember that backing up files is always
a good idea!
If you want to make life tougher yet for people trying to
get your data, (1) you can encrypt your files before you run them through
Pryvit privacy protection, and/or (2) you can do your own cascading,
withdrawing some of the archive files at each stage, and/or (3) you can do your own cascading, using
a different computer for each stage. That is more work for you, but the
security is superb.
