Appeal 2007-0820
Application 09/734,808
1 Dethloff et al discloses bio-authentication
2 information as the identification information
3 further as a voice sensor (col 11, lines 25-30), a
4 local storage device for the memory further where
5 the memory is part of the consumer electronics
6 device (col 11, lines 2-24), sending account holder
7 information over the communication link, a match
8 detected and determining a sub-credit limit that is
9 not exceeded (col 13, lines 67-68; col 14,
10 lines 1-8).
11 (Answer 5.) We agree with the Examiner that Dethloff discloses that instead
12 of using a PIN for authentication, a voice print (a type of bioauthentication)
13 may be used as the sub-user enabling code (FF 18). As such, Dethloff
14 teaches that it was known in the art at the time of the invention to substitute
15 a PIN authentication with bioauthentication to enable a user to access credit
16 via a consumer electronics device (FF 18).
17 We find, based on our examination of the prior art and the state of the
18 art in consumer electronic devices, that the art evidences a common usage of
19 personal codes or personal identification numbers (PINs) to identify or
20 authenticate users (FF 19). The art further shows that one of ordinary skill
21 in the consumer electronic device art at the time of the invention would have
22 been familiar with using bioauthentication information interchangeably with
23 or in lieu of PINs to authenticate users (FF 20). It is also clear from an
24 examination of the prior art that those of ordinary skill in the consumer
25 electronic device art at the time of the invention would have been familiar
26 with using bioauthentication devices to obtain bioauthentication information
27 to identify users (FF 21).
