Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 20-21, 23, 27, 28 are rejected under 35 U.S.C. 102(a)(1) as being anticipated  by Bouatou et al. (US Pub. 2016-125179 A1).
Bouatou discloses the following limitations:
20. (currently amended) A method comprising:
capturing, at a first self-service kiosk, live biometric data of a person, the live biometric data including a facial image of the person (para. 26- When arriving at the check-in desk 6, the traveller 1 shows his/her ticket, his/her biometric passport 2 and places his/her right hand on the fingerprint scanner 10. The check-in officer launches, in a single operation, the acquisitions 11.1, 11.2, 11.3, 11.4 and 11.5 of the traveller's 1 fingerprints with the fingers being respectively placed on the acquisition pads 10.1 to 10.5 of the fingerprint scanner 10.; para. 12- biometric characteristics acquired are advantageously selected from the following ones: fingerprint, vein, face, iris, skin texture, peri-ocular venous pattern; note- image of eye = facial image of the person; para. 33- The first biometric characteristic may also match the iris image of an eye and the second biometric characteristic may be the peri-ocular venous pattern of the same eye);
extracting, at the first self-service kiosk, reference biometric data from a biometric identification document, the reference biometric data including a reference facial image (para. 26- The biometric passport 2 is, in turn, placed on a specific reader that provides access to information contained in the secured chip 3, specifically the certified records 4 and 5 of the traveller's 1 right hand index and middle finger prints.);
comparing the facial image with the reference facial image of the reference biometric data extracted from the biometric identification document to verify an identity of the person (para. 26- The acquisitions 11.2 and 11.3 corresponding to the traveller's index and middle fingers prints are then compared with the certified records 4 and 5 contained in the secured chip 3 of the biometric passport 2.; para. 33- The first biometric characteristic may also match the iris image of an eye);
in response to verification of the identity of the person, storing enrollment data associating including (i) the facial image used for comparison with the reference facial image and (ii) additional data corresponding to the person (para. 26-  Upon completion of the comparison, the secured chip 3 transmits a piece of information indicating whether the biometrics characteristics are identical with or different from the certified records 4 and 5. If the acquisitions 11.2 and 11.3 match the records 4 and 5, the traveller 1 is identified as the passport holder and his/her civil status is confirmed. The server 12 then stores in a catalogue 15 of second biometric characteristics, the acquisitions 11.1, 11.4 and 11.5 corresponding to the traveller's 1 thumb, ring finger and little finger prints and then associates therewith a secondary identifier 16, here the traveller's flight number 1 together with his/her seat number on the plane,; para. 33- the second biometric characteristic may be the peri-ocular venous pattern of the same eye);
subsequent to storing the enrollment data, capturing, at a second self- service kiosk, further live biometric data of the person, the further live biometric data including a further facial image of the person (para. 33- the second biometric characteristic may be the peri-ocular venous pattern of the same eye.);
in response to capturing the further live biometric data, retrieving the enrollment data; comparing the further facial image with the facial image of the enrollment data to authenticate the person (para. 27- The acquisitions of the thumb, ring finger and little finger prints are sent to the server 12 which, after comparison, matches the acquired fingerprints and the acquisitions 11.1, 11.4 and 11.5 saved in the catalogue 15 and returns a message indicating the traveller's 1 secondary identifier 16, i.e. his/her flight number and seat on the plane to the remote display screen 11, to the attention of the security officer in charge of the check-point 7. The security officer then knows that the traveller 1 has regularly checked-in on one of the departing flights and the server 12 records that the traveller 1 has checked in his/her luggage; para. 33- the second biometric characteristic may be the peri-ocular venous pattern of the same eye.); and
in response to authenticating the person based on the comparison of the further facial image with the facial image of the enrollment data, granting the person access to a restricted area, at the second self-service kiosk. (para. 27- The traveller's 1 identification at the access point 8 to the boarding area takes place in the same manner and the server 1 records that the traveller has crossed the access point 8 to the boarding area. Thus, when checking in at the plane boarding desk 9, the traveller 1 identifies again as per his/her secondary identifier by scanning his/her thumb, his/her ring finger and his/her little finger prints. The server 12 confirms that the person whose thumb, ring finger and little finger prints have just been read is the traveller 1, that he/she actually went through all the check-points prior to the flight and that he/she can therefore enter the plane.; para. 33- The first biometric characteristic may also match the iris image of an eye and the second biometric characteristic may be the peri-ocular venous pattern of the same eye)
21. (previously presented) The method of claim 20, further comprising, at the first self-service kiosk: extracting a portion of the additional data, comprising a unique identification number, from the biometric identification document. (para. 30- The scanner 54 reads the data 55 of the area 53. It is connected to a processing unit 56 which queries in a manner known per se, the biometric characteristic data base 57 associating MRZ area data and certified records of biometric characteristics. The processing unit 56 identifies the field 58 of the database 57 containing the information 55 and then uses the certified records 4 and 5 of the traveller's right hand prints of his/her index and middle finger associated with the field 58 to make a comparison with the acquisitions 11.2 and 11.3.)
23. (previously presented) The method of claim 20, wherein storing the enrollment data includes storing the enrollment data in a central database. (paras. 26-27- server 12)
Claims 22 and 29 are rejected under 35 U.S.C. 103 as being unpatentable over Bouatou and further in view of Gormley et al. (US Pub. 20130305059 A1).
Regarding claim 22, Bouatou does not specifically teach wherein storing the enrollment data includes encrypting the enrollment data with a key generated from at least a portion of the additional data.  However, in the related art of using biometric passports, Gormley teaches storing the enrollment data includes encrypting the enrollment data with a key generated from at least a portion of the additional data. (see paras. 48-50).  Therefore, one of ordinary skill in the art as of the effective filing date of the claimed invention, would have found it obvious to use this teaching of Gormely  with the disclosure of Bouatou as a known way of protecting the enrollment data from an eavesdropper intercepting the data as suggested by Gormley.
Claims 24 and 30 are rejected under 35 U.S.C. 103 as being unpatentable over Bouatou and further in view of Hoyos et al. (US Pub. 20080122578 A1)
Regarding claim 24 (currently amended), although Boutaou teaches storing enrollment data for a traveller on an airplane, it does not specifically teach storing, in the central database a plurality of additional sets of enrollment data corresponding to respective additional persons; wherein retrieving the enrollment data includes performing a search of the central database, based on the further live biometric data.  However, in the related art of identifying passengers at various checkpoints, Hoyos teaches storing, in the central database a plurality of additional sets of enrollment data corresponding to respective additional persons; wherein retrieving the enrollment data includes performing a search of the central database, based on the further live biometric data.  (see Fig. 1, para. 9, 20- image database (i.e. central database) storing plurality of biometric templates being made available for authentication) and therefore, one of ordinary skill in the art as of the effective filing date of the claimed invention would have found it obvious to use this teaching of Hoyos with the disclosure of Boutaou as a known way of using biometrics to authenticate multiple passengers through a secondary security check point such as at a boarding area/gate area.
Claims 26 and 32 are rejected under 35 U.S.C. 103 as being unpatentable over Boutaou and further in view of Fukuda (US Pub. 200226048 A1)
Regarding claim 26 (new), Boutaou does not specifically teach when an authentication requirement for the person ends, deleting the enrollment data. However, this concept of deleting biometric data of a user after the ending of an authentication requirement is known and used in the art of biometric authentication as evidenced by Fukuda (see para. 44, claim 6) and therefore, one of ordinary skill in the art as of the effective filing date of the claimed invention would have found it obvious to use this teaching of Fukuda with the disclosure of Boutaou as a known way of preventing unauthorized future use of a user’s biometric data.
Regarding claims 27-30, 32 they are rejected as applied to claims 20-22 and 24, 26 because a corresponding system would have been necessitated to carry forth the method steps of claims 27-30, 32.  The applied prior art also discloses the corresponding architecture.  (see Figs. 1, 3, 4)

uments:
Claim Rejections Under 35 USC 102 and 103
" Claims 20-21, 23, 27, and 28 stand rejected as being anticipated by
Bouatou (US 2016/0125179)
" Claims 22 and 29 stand rejected as being obvious in view of Bouatou and
Gormley (US 2013/0305059)
" Claims 24 and 30 stand rejected as being obvious in view of Bouatou and
Hoyos (US 2008/0122578)
" Claims 26 and 32 stand rejected as being obvious in view of Bouatou and
Fukuda (US 2009/0226048)
Applicant submits that the claims as amended are patentable. Bouatou does not disclose at least the following limitations of independent claim 20, or the equivalent limitations of independent claim 27:
"in response to verification of the identity of the person, storing enrollment data including (i) the facial image used for comparison with the reference
facial image, and (ii) additional data corresponding to the person"
The "reference image" recited above is, as detailed earlier in claim 1, extracted from a biometric identification document. Bouatou discloses a biometric passport storing a first biometric characteristic such as index and middle fingerprints. To verify a traveler's identity, Bouatou calls for capturing all five fingerprints ("acquisitions" 11.1 through 11.5, see Bouatou, paragraph 0026). Bouatou then handles subsets of the fingerprints
differently,
however. Specifically, the acquisitions 11.2 and 11.3 are compared with the fingerprints extracted from the biometric passport.
When the acquisitions 11.2 and 11.3 match the data from the biometric passport, Bouatou stores a
distinct
second biometric characteristic. As set out in paragraph
0026, Bouatou's server 12 stores the acquisitions 11.1, 11.4, and 11.5, explicitly
omittin
g
the fingerprints used for verification. In other words,
only
the acquisitions 11.2 and 11.3 are used for the initial comparison, and
only
the acquisitions 11.1, 11.4., and 11.5 are stored for later authentication. There is
no overlap
between the data used for comparison with the reference data and the stored enrollment data. Bouatou plainly does not disclose the above claim limitations, which call for storing the
same
data that is compared with the reference data.
The claim rejections fail to account for the distinction set out above. The office action notes, for example:
" at the middle of page 5, that paragraph 0033 of Bouatou states that the
"first biometric characteristic may also match the iris image of an eye"
" near the top of page 6, that paragraph 0033 of Bouatou states that the
"second biometric characteristic may be the peri-ocular venous pattern of
the same eye or the other eye"
The office action, in other words, appears to imply that an iris image can be substituted for the fingerprints for identity verification (in which case a biometric passport contains a reference iris image), and that a peri-ocular venous pattern is
equivalent
to an iris image, such that storing the peri-ocular venous pattern in Bouatou's server 12 would satisfy the claimed storage of the image used for verification. The above equivalence is mistaken, however. A peri-ocular venous pattern is mutually exclusive with an image of an iris. The plain meaning of peri- ocular is surrounding the eye. A pattern of veins surrounding a person's eye is plainly not the same thing as an image of that person's iris, and storing one is not equivalent to storing the other. The mere mention of two loosely related (by virtue of being associated with a person's eye) biometric characteristics in Bouatou does not indicate that Bouatou stores enrollment data including the facial image used for comparison with a reference facial image, as claimed.
Further, as also noted in Applicant's previous response, Bouatou explicitly teaches
ag
ainst
storing the same biometric data as is used for verification for later authentication. See, for example, paragraph 0011 of Bouatou, which states that "the second biometric characteristic is different from the first biometric characteristic stored in the certified data medium and the secondary identifier is different from the primary identifier', and that "the primary identifier
cannot be found using the second biometric characteristic
and the secondary identifier' (emphasis added). See also paragraph 0026 of Bouatou, which states that "It should be noted that the acquisitions 11.2 and 11.3 of the traveller's 1 index and middle
fingerprints are not saved
in the server 12" (emphasis added).
Applicant submits that Gormley, Hoyos, and Fukuda also lack the above claim limitations. The claims are patentable for at least the above reasons. Reconsideration and allowance of all pending claims is respectfully requested.
Conclusion

NEXT OFFICE ACTION: DETAILED ACTION
Notice of Pre-AIA  or AIA  Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Reasons for Allowance
Claims 20-24, 26-30 and 32 are allowed.
The following is an examiner’s statement of reasons for allowance:
The primary reason for allowance is that the prior art of record fails to teach or render obvious the following subject matter in combination with other elements of the independent claims as well as Applicant’s arguments of record as to the distinguishing claim features over the applied prior art being persuasive; “in response to verification of the identity of the person, storing enrollment data including (i) the facial image used for comparison with the reference facial image, and (ii) additional data corresponding to the person; subsequent to storing the enrollment data, capturing, at a second self- service kiosk, further live biometric data of the person, the further live biometric data including a further facial image of the person; in response to capturing the further live biometric data, retrieving the enrollment data; comparing the further facial image with the facial image of the enrollment data to authenticate the person; and in response to authenticating the person based on the comparison of the further facial image with the facial image of the enrollment data, granting the person access to a restricted area, at the second self-service kiosk.”
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee.  Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
