FIGURE 11 is a diagram showing aspects of the index
file 0260, a support output of the system and method 0110. This index file 0260 is a
disguised listing of directory locations and names of original data files 0220, together
with subsidiary information on each file. All of the index file 0260 except the subsidiary
information is text. The entire content is disguised prior to the index file 0260 becoming
part of a privacy protected archive 0261.
Each directory tree entry 1110 (for example,
">c:\data\personal\MyFinances") starts with a "greater than" symbol and finishes
with a terminating null.
After each directory location entry 1110 there
may be one or a plurality of names 1120 of original data files 0220 drawn from that
directory.
After the terminating null of each file name 1120
appear four binary data elements which are supplementary file information 1130. The
first supplement 1130 is a one byte value (0...15) indicating the input stream 1131
during fragmentation 1740. Next is a four byte date-time stamp 1132 corresponding to
the displayed time and data 0570 for that file in FIGURE 05. The third supplement 1130
is the size 1133 of the file in bytes 0560 in the form of a compressed integer 1240.
The fourth supplement 1130 is the offset 1134 of the first byte of the directory
location 1110 applicable to this file earlier within this index file 0260. Offset
1134 is also recorded in the form of a compressed integer 1240. These subsidiary
data elements enable later restoration of the directory location 0530, original data
file name 0540, and time stamp 0570 of the original data file 0220 and optionally
verifying the size 0560 when the original data file 0220 is reproduced by the procedure
to reconstitute privatized data 0160.
