Appeal No. 1997-3178
Application 08/464,069
identity of the legitimate computer user, and after positive
confirmation of identity, recovering the secret digital
information." Claim 25 recites recovering "secret encrypted
digital information" instead of recovering "secret digital
information" as recited in claim 32. In claims 25 and 32,
the trustee uses the "digital data structure" to confirm the
user identity, not just the "identifying information"
portion of the "digital data structure"; thus, the trustee
could use all or part of the digital data structure.
Furthermore, claims 25 and 32 do not recite how the trustee
recovers the secret (encrypted) digital information from the
digital data structure; the secret digital information could
be encrypted with a public key (as in Kaufman) and the
trustee could just apply its private key (as in Kaufman) to
decrypt and recover the information.
