Claim 2:
3. The apparatus of claim 1, wherein:
the storage device comprises a plurality of storage sectors;
performing the set of overwrite operations on the storage device comprises performing the set of overwrite operations on the plurality of storage sectors to data wipe each of the plurality of storage sectors; and
the executable code further causes the processor to:
encrypt the set of auditable traces on a data wiped storage sector of the plurality of data wiped storage sectors,
write an eyecatcher to the data wiped storage sector such that the eyecatcher and the encrypted set of auditable traces are co-located on the data wiped storage sector,
scan the plurality of data wiped storage sectors to locate the eyecatcher,
in response to locating the eyecatcher on the data wiped storage sector on which the eyecatcher and the encrypted set of auditable traces are co-located, attempt to decrypt the encrypted set of auditable traces on the data wiped storage sector,
validate the data wipe in response to being able to decrypt the encrypted set of auditable traces, and
invalidate the data wipe in response to being unable to decrypt the encrypted set of auditable traces.
