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 .
Status of Claims
This office action is a response to an amendment filed on 07/13/2026. Claims 1, 9, 15, 17 and 20 are amended, and claims 2, 10 and 16 cancelled. Claims 1, 3-9, 11-15 and 17-20 are currently pending.
Response to Arguments
Applicant’s remarks, see pages 9-12, with respect to the rejections under 35 USC 103 have been fully considered but are not persuasive. Amended independent claims 1, 9 and 15 incorporate the limitations of former claims 2, 10, and 16, respectively, and the rejections are maintained over Lee in view of Fu and Carlson.
Applicant argues that Carlson does not teach: (1) “the certification information adding part notifies the authentication part of certification information concerning a communication rule in advance”; (2) “the certification information includes each size of the plurality of blocks of the first biometric information which is divided to the plurality of blocks to be arranged in the authentication information and the predetermined transmission order of the plurality of blocks”; and (3) the authentication part “verifies legitimacy of the certification information in the authentication information using the certification information notified in advance from the certification information adding part”.
These arguments are not persuasive because the rejection is based on the combined teachings of Lee, Fu and Carlson, rather than Carlson alone.
Fu discloses that communication rule information – including codes, preparation or measurement basis, authentication information lengths – are preset by the transmitter and receiver or negotiated through a predetermined channel before transmission, and that the receiver later processes and verifies the received authentication information according to the corresponding established rule (Fu, [0013], [0036], [0058], [0174]). Therefore, Fu discloses “the certification information adding part notifies the authentication part of certification information concerning a communication rule in advance” and “verifies legitimacy of the certification information … using the certification information notified in advance”.
Carlson discloses dividing digital information into blocks, arranging the blocks in an order before transmission, and adding the “order, size, and geometry of the blocks” to the reassembled file so that the receiver can correctly reassemble the blocks (Carlson, [0149], [0152]-[0154], [0157], [0171]). Therefore, Carlson discloses “the certification information includes each size of the plurality of blocks … and the predetermined transmission order of the plurality of blocks”. In the proposed combination, Carlson’s block size and block order information is incorporated into Fu’s certification information concerning the communication rule and applied to Lee’s first biometric information.
Lee discloses verifying whether an expected secure watermark pattern is included in received biometric information during primary authentication and performing biometric comparison only after that verification succeeds (Lee, [0080], [0083]-[0085]). Therefore, Lee discloses “verifies legitimacy of the certification information in the authentication information”, while Fu supplies the previously established communication rule used in that verification.
It would have been obvious to one of ordinary skill in the art, having the teachings of Lee, Fu and Carlson before him or her before the effective filing date of the claimed invention, to modify a biometric authentication system as taught by Lee, to use previously established communication rules as taught by Fu, and block size and block order information as taught by Carlson. In the resulting combination, Carlson’s block information would form part of the certification information provided in advance under Fu’s framework and would be checked during Lee’s primary verification stage before biometric authentication. The motivation for doing so would have been to permit the receiving apparatus to correctly reassemble the transmitted biometric information, thereby enabling the biometric comparison to be performed using properly reconstructed biometric information and improving the reliability of the authentication process.
Hence, Carlson does not need to independently disclose the advance notification or legitimacy verification portions of the disputed limitations because those portions are supplied by Fu and Lee. Carlson supplies the block sizes and predetermined block order incorporated into the certification information.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(d):
(d) REFERENCE IN DEPENDENT FORMS.—Subject to subsection (e), a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
The following is a quotation of pre-AIA 35 U.S.C. 112, fourth paragraph:
Subject to the following paragraph [i.e., the fifth paragraph of pre-AIA 35 U.S.C. 112], a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.
Claims 4, 7, 12 and 18 are rejected under 35 U.S.C. 112(d) or pre-AIA 35 U.S.C. 112, 4th paragraph, as being of improper dependent form for failing to further limit the subject matter of the claims upon which they depend, or for failing to include all the limitations of the claims upon which they depend.
As amended, independent claims 1, 9 and 15 already recite that the first biometric information is divided into a plurality of blocks arranged in a predetermined transmission order according to the communication rule, and that the certification information includes each block size and the predetermined transmission order. Claims 4 and 7 depend, directly or indirectly, from claim 1; claim 12 depends indirectly from claim 9; and claim 18 depends indirectly from claim 15, but merely repeat those same limitations. Therefore, claims 4, 7, 12 and 18 do not further limit the subject matter of their respective parent claims.
Applicant may cancel the claim(s), amend the claim(s) to place the claim(s) in proper dependent form, rewrite the claim(s) in independent form, or present a sufficient showing that the dependent claim(s) complies with the statutory requirements.
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 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 of this title, 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.
Claims 1, 9 and 15 are rejected under 35 U.S.C. 103 as being unpatentable over Lee et al. (US 2015/0365406), hereinafter Lee, in view of Fu (US 2017/0054556), further in view of Carlson et al. (US 2014/0325233), hereinafter Carlson.

wherein the first biometric information in the authentication information transmitted from the certification information adding part to the authentication part is configured (Lee, [0052]: biometric information generation module (certification information adding part) generates biometric information for authentication (authentication information) by inserting a watermark pattern (certification information) into a biometric image (first biometric information); [0080]: biometric information authenticating apparatus (authenticating part) receives the biometric information for authentication (authentication information)).

It would have been obvious to one of ordinary skill in the art, having the teachings of Lee, Fu and Carlson before him or her before the effective filing date of the claimed invention, to modify a system for transmitting biometric and associated authentication information using preset or negotiated communication rule as taught by Lee and Fu, to division of the biometric information into blocks and inclusion of block size and block order information as taught by Carlson. The motivation for doing so would have been to ensure that the receiving authentication apparatus could correctly reassemble the transmitted biometric information, thereby enabling the biometric comparison to be performed using properly reconstructed biometric information and improving the reliability of the authentication process.

However, Fu discloses

It would have been obvious to one of ordinary skill in the art, having the teachings of Lee and Fu before him or her before the effective filing date of the claimed invention, to modify a biometric information transmission and authentication system as taught by Lee, to include transmitting authentication information and data according to a negotiated rule, and enabling the receiver to process and verify the received information using the same rule as taught by Fu. The motivation for doing so would have been to ensure certification information and biometric information are consistently structured and correctly interpreted by the receiving authentication apparatus, thereby improving the reliability and robustness of the authentication process.
Furthermore, the combination of Lee and Fu does not explicitly disclose configured in such way that the first biometric information is divided to a plurality of blocks to be arranged in a predetermined transmission order according to the communication rule; and wherein the certification information includes each size of the plurality of blocks of the first biometric information which is divided to the plurality of blocks to be arranged in the authentication information and the predetermined transmission order of the plurality of blocks.
However, Carlson discloses

However, Connell discloses wherein the processor is configured to execute the program instructions to implement:
a conversion key generation part which generates a conversion key (Connell, [0033]: “ The parameters used to generate the texture image and the combination method (conversion transform function(s), e.g. add, subtract, etc.) are stored as a key .... The key includes the synthetic texture patterns and the operations for how these patterns were combined with the unwrapped iris image”; [0050]: “The pattern or patterns … may be … randomly generated using transform generator”; and
a biometric information conversion part which converts the first biometric information acquired by the biometric information acquiring part based on the conversion key and transmits the converted first biometric information (Connell, [0032]: “An original image 108 is combined with the synthetic image using an operation such as add, subtract, multiply, divide or more complicated combinations or relationships”; [0051]: “A combining module 408 is configured to combine pixels of the at least one pattern in block 404 with the biometric image 403 or unwrapped image 411 by employing a transform pixel operation 410 to generate a transformed image”; [0052]: “The transformed image may be sent to a secure server 422 for matching”);
wherein the second biometric information of the user in the biometric information database has been converted based on the conversion key (Connell, [0011]: “at least one pattern is combined with the biometric image by employing a transform pixel operation to generate a transformed enrollment. The same pattern or patterns and the same transform pixel operation or operations are applied to a query to enable matching of the query to the enrollment to verify an identity.”; [0035]: “If it is an enrollment procedure, the resulting template … is suitable for enrollment in a database”; [0062]: “This enrollment 525 is later employed for matching against transformed feature 517 of a query presentation of user”. [enrollment/template = second biometric information]).
It would have been obvious to one of ordinary skill in the art, having the teachings of Lee, Fu Carlson and Connell before him or her before the effective filing date of the claimed invention, to modify a system that captures and transmits biometric information to an authentication apparatus as taught by Lee, Fu and Carlson, to include applying biometric transformation techniques as taught by Connell. The motivation for doing so would have been to enhance the security and privacy of biometric data by allowing biometric authentication to be performed while preventing exposure of the original biometric data.
Regarding claim 7, Lee discloses wherein the first biometric information in the authentication information transmitted from the certification information adding part to the authentication part is configured (Lee, [0052]: biometric information generation module (certification information adding part) generates biometric information for authentication (authentication information) by inserting a watermark pattern (certification information) into a biometric image (first biometric information); [0080]: biometric information authenticating apparatus (authenticating part) receives the biometric information for authentication (authentication information)).

wherein the certification information includes each size of the plurality of blocks of the first biometric information which is divided to the plurality of blocks to be arranged in the authentication information and the predetermined transmission order of the plurality of blocks (Carlson, [0154]: order, size and geometry of the block (certification geometry) is appended to the front of the assembled file).
It would have been obvious to one of ordinary skill in the art, having the teachings of Lee, Fu and Carlson before him or her before the effective filing date of the claimed invention, to modify a system for transmitting biometric and associated authentication information using structured communication and biometric transformation techniques as taught by Lee and Fu, to include applying block-based data segmentation, ordering and inclusion of block metadata in the transmitted data as taught by Carlson. The motivation for doing so would have been to facilitate reliable transmission and reconstruction of the biometric information and associated authentication information.
Regarding claim 8, Lee, Fu and Carlson do not explicitly disclose wherein the conversion based on the conversion key is a one-way conversion.
However, Connell discloses wherein the conversion based on the conversion key is a one-way conversion (Connell, [0026]: “It is secure because an original iris pattern cannot be recovered even from a “cracked” package.”; [0041]: “These methods are non-invertible as all original pixel intensities or code strings are “damaged … Hence, the present methods are non-invertible, thus guaranteeing privacy” [non-invertible = one-way]).
It would have been obvious to one of ordinary skill in the art, having the teachings of Lee, Fu, Carlson and Connell before him or her before the effective filing date of the claimed invention, to modify a system that captures and transmits biometric information to an authentication apparatus as taught by Lee, Fu and Carlson, to include applying biometric transformation techniques as taught by Connell. The motivation for doing so would have been to enhance the security and privacy of biometric data by allowing biometric authentication to be performed while preventing exposure of the original biometric data.
Regarding claims 14 and 20, the limitations have been addressed in the rejection of claim 6.
