Appeal No. 1997-3178
Application 08/464,069
DECISION ON APPEAL
This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 25, 26, and 29-46.
We affirm-in-part.
BACKGROUND
The disclosed invention involves the problem of
confirming the identity of a user who is seeking to recover
secret information, such as a lost password, using a
trustee. The trustee must have some way to positively
identify the user so that the secret information will not be
revealed to an imposter. A data structure holds both
standard information identifying the legitimate user,
encrypted private information which only the user knows and
which is used by the trustee to verify identity, and
encrypted secret information. The trustee decrypts the
encrypted portions of the data structure, uses the standard
and private information to verify the identity of the user,
and transmits the decrypted secret information (such as a
password) to the user.
