Appeal No. 1997-3178
Application 08/464,069
Claim 25 is reproduced below.2
25. A computer having a legitimate user of the
computer including a processor and a memory device
coupled to said processor, a digital data structure
corresponding to the legitimate user stored in said
memory device including:
identifying information identifying the legitimate
computer user, and
secret encrypted digital information other than
said identifying information,
wherein the digital data structure is used by a
trustee to confirm the identity of the legitimate
computer user and to recover the secret encrypted
digital information.
The Examiner relies on the following prior art:
Cole et al. (Cole) 5,091,939 February 25, 1992
Hardy et al. (Hardy) 5,222,135 June 22,
1993
Kaufman et al. (Kaufman) 5,418,854 May 23,
1995
(filed April 28,
1992)
Dziewit et al. (Dziewit) WO 92/09161 May

(International application published under the PCT)
We question whether the phrase "to recover the secret2
encrypted digital information" is correct. This suggests that
the trustee does nothing since the information is still
encrypted. Perhaps it was intended that the trustee recovers
"the secret digital information" as recited in claim 32.
