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 .
Claim Rejections - 35 USC § 101
35 U.S.C. 101 reads as follows:
Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
Claim 15 is rejected under 35 U.S.C. 101 because the claimed invention is directed to non-statutory subject matter. The claim(s) does/do not fall within at least one of the four categories of patent eligible subject matter because the claim, claims a “program” which is non-statutory subject matter. A potential amendment could be to state the computer first such as “A computer with a program stored thereon for performing…”. Another potential option is to cancel the claim. Appropriate correction is required.
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 1-4, 7, 11, and 13-15 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou et al., CN 108319901 A (Zhou), and further in view of Ajiki et al., WO 2018181819 A1 (Ajiki).
Regarding claim 1, Zhou teaches an information processing apparatus (living body detection of a human face device) (p. 1; Abstract) that performs non-contact authentication of a living body using an image (living human face detection and authentication) (p. 1; Abstract and p. 11; last paragraph), the information processing apparatus (living body detection of a human face device) (p. 1; Abstract) comprising:
a control unit that acquires a difference image acquired by an image plane difference sensor (capturing an image using a mobile terminal that determines if the face and background are on the same plane) (p. 13; 5th-9th paragraphs),
detects a background from the difference image (detecting a background area/region from the image) (p. 13; 9th paragraph to p. 14; 1st paragraph), and
determines whether or not impersonation has occurred (determining if an attack (imposter) is happening) (p. 14; 1st-3rd paragraphs) on a basis of a comparison with a focus position of the image plane difference sensor in at least a part of the background (on the basis if the face of the person in the image is on the same plane as the background; realizing that it is an attack such as a 2D printed photo) (p. 14; 1st-3rd paragraphs).
Although Zhou teaches the difference between planes (phases) of the background and a face (p. 14; 1st-3rd paragraphs), Zhou does not explicitly teach a “phase difference” image or a “phase difference” sensor.
Ajiki teaches a facial authentical device (p. 1; Abstract); wherein the imaging element has a function of acquiring two-dimensional image data and image plane phase difference information of the authentication target person's face (p. 4; 5th paragraph); and wherein the image plane phase difference information of the authentication target person's face is the distance in the depth direction from the best focus surface of the imaging optical system 3 of each part of the authentication target person's face (p. 5; 1st paragraph).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify Zhou to include an explicit phase difference imaging since it allows for the use of a single image sensor which then the face authentication device can be reduced in size, power consumption, and cost (Ajiki; p. 5, 2nd paragraph).
Regarding claim 2, Zhou teaches wherein the control unit determines that impersonation has occurred when determining that at least a part of the background is same as the focus position of the image plane difference sensor or is closer to the image plane difference sensor with respect to the focus position (determining if an attack (imposter) is happening on the basis if the face of the person in the image is on the same plane as the background; realizing that it is an attack such as a 2D printed photo) (p. 14; 1st-3rd paragraphs).

Claim(s) 5 and 6 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou et al., CN 108319901 A (Zhou), Ajiki et al., WO 2018181819 A1 (Ajiki), and further in view of Tamura, US 2022/0245979 A1 (Tamura).
Regarding claim 5, Zhou teaches wherein the control unit determines that impersonation (determining if an attack (imposter) is happening) (p. 14; 1st-3rd paragraphs) has not occurred in a difference image (on the basis if the face of the person in the image is not on the same plane as the background; realizing that it is the real human face and the environment is three-dimensional) (p. 14; 1st-3rd paragraphs). Ajiki teaches a facial authentical device (p. 1; Abstract); wherein the imaging element has a function of acquiring two-dimensional image data and image plane phase difference information of the authentication target person's face (p. 4; 5th paragraph).
However, neither explicitly teaches determining if the background information is insufficient and thus impersonation has not occurred.
Tamura teaches facial recognition that the person is a pass-authorized person (Abstract); and wherein if the background information is insufficient (i.e. due to outside light and erroneously determined, thus no info about the actual background) ([0034]) that impersonation has not occurred (false determination and thus impersonation has not occurred) ([0034]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of prior arts to include detecting if the background information is insufficient since it allows for facial image authentication (Tamura; Abstract) while achieving both convenience and maintain a security level (Tamura; [0012]).
Regarding claim 6, Zhou teaches wherein the control unit determines that impersonation (determining if an attack (imposter) is happening) (p. 14; 1st-3rd paragraphs) has occurred in a difference image (on the basis if the face of the person in the image is on the same plane as the background; realizing that it is an attack such as a 2D printed photo) (p. 14; 1st-3rd paragraphs). Ajiki teaches a facial authentical device (p. 1; Abstract); wherein the imaging element has a function of acquiring two-dimensional image data and image plane phase difference information of the authentication target person's face (p. 4; 5th paragraph).
However, neither explicitly teaches determining if the background information is insufficient and thus impersonation has occurred.
Tamura teaches facial recognition that the person is a pass-authorized person (Abstract); and wherein if the background information is insufficient (i.e. high luminance region; thus no info about the actual background) ([0033]) that impersonation has occurred (impersonation is performed) ([0033]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of prior arts to include detecting if the background information is insufficient since it allows for facial image authentication (Tamura; Abstract) while achieving both convenience and maintain a security level (Tamura; [0012]).
Claim(s) 8-10 are rejected under 35 U.S.C. 103 as being unpatentable over Zhou et al., CN 108319901 A (Zhou), Ajiki et al., WO 2018181819 A1 (Ajiki), and further in view of Kato et al., US 2020/0143186 A1 (Kato).
Regarding claim 8, Zhou teaches wherein the control unit with face area for a user so that the difference image includes the living body and the background (detecting the preset area of the human face to be tested is located in the display screen of the mobile terminal) (p. 13; step 300) (using the face feature point detection algorithm may locate the human face position to be detected under the different visual images, based on the square, as the face area, then selecting a certain proportion of the surrounding area as background area for plane verification) (p. 14; 2nd paragraph). Ajiki teaches a facial authentical device (p. 1; Abstract); wherein the imaging element has a function of acquiring two-dimensional image data and image plane phase difference information of the authentication target person's face (p. 4; 5th paragraph).
However, neither explicitly teaches to “guide” a user.
Kato teaches face authentication for a user ([0026]); and wherein the information provide unit and provide guidance information to the user ([0047]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of prior arts to include providing guidance information to the user since it allows for successful acquisition of the predefined number of face images by the face image acquisition unit for face authentication (Kato; [0047]).
Regarding claim 9, Kato teaches wherein the control unit notifies a user to change the background (notifying the user to change the environment they are in because the background is too dark or too bright) ([0048], [0050-0051]).
Regarding claim 10, Kato teaches wherein the control unit guides the user so that a part of the user other than the living body used for the authentication is included in the background (wherein the user can be guided to move either closer or further away; thus, by moving further away adding addition parts of the user) ([0052]).
Claim(s) 12 is rejected under 35 U.S.C. 103 as being unpatentable over Zhou et al., CN 108319901 A (Zhou), Ajiki et al., WO 2018181819 A1 (Ajiki), and further in view of Ebihara, US 2021/0034894 A1 (Ebihara).
Regarding claim 12, Zhou teaches determining if an attack (imposter) is happening (p. 14; 1st-3rd paragraphs). Ajiki teaches facial authentication (Abstract).
However, neither explicitly teaches “wherein the control unit does not perform the authentication of the living body when determining that impersonation has occurred”.
Ebihara teaches a spoofing detection apparatus (Abstract); such as if a two-dimensional shape as the feature value appears, it is determined that the captured face is a fake face shown in a photograph or on a display ([0046]); and wherein the control unit does not perform the authentication of the living body when determining that impersonation has occurred (if the detection result does not indicate a real human, the apparatus stops authentication processing) ([0082]).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the combination of prior arts to include stopping authentication since it saves processing time and power.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Prior art Suzuki, WO 2009110323 A1: teaches the distance acquisition unit acquires a living body distance between an object to be imaged in the living body region and the imaging unit and a non-living body distance between the object to be imaged in the non-living body region and the imaging unit (p. 1; Abstract); and wherein the living body/background distance comparison unit compares the living body distance with the non-living body distance to judge whether or not the living body is the real (p. 1; Abstract).
