The steps in FIGURE 24 allow the author
to set passwords to be built into new copies of the reconstitution file
0270 and 2310.
In step 2410, specify a signature file
2250 from the list 2350.
In step 2420, specify a password and
confirm it.
Step 2430 provides an option to assign
the same password to all new reconstitution files that will be constructed
in the next step.
In step 2440, the author creates new
reconstitution file(s), one for each signature file which is to be granted
access. The underlying steps are (a) to undo the encryption of step 2160,
(b) remove the author-computer-specific disguise of step 2150, (c) replace
the computer identifier field 1330, (d) change the reconstitution file type
1320 to either "B" backup or "D" distribution, (e) replace the password
1340 with the selection 2430, (f) replace the disguise, now with one based
on the computer signature file for the target requester's computer, and (g)
encrypt again as in step 2160. In the Windows implementation, each new
reconstitution file 0270 was given the same name as the original; this was
placed in a subdirectory named for the requester's signature file
2250.
In step 2450, the author transmits the
new reconstitution file(s) to the intended receivers by some appropriately
secure means.
On receipt, the user is able to access
the privacy protected archive using the procedure to reconstitute
privatized data 0160 that has been dispersed to Internet locations
0440.
