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 .
DETAILED ACTION
Claims 1-19 are presented for examination.
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, 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.
3. Claims 1-19 are rejected under 35 U.S.C. 103 as being unpatentable over KALACH et al hereafter KALACH (US pat. App. Pub. 20220109559) and in view of LEE et al hereafter LEE (US pat. App. Pub. 20170019250).
4. As per claims 1, and 18-19, KALACH discloses a signal processing device, a monitoring system, and a signal processing method comprising: a first processing unit; and a second processing unit that transmits, to the first processing unit, sensing data and first encryption information obtained by encrypting a part of the sensing data (paragraphs: 12-22, wherein it emphasizes a processing unit encrypt a portion of the data and sends it to another processing unit), wherein the second processing unit includes a first encryption unit that generates the first encryption information by encrypting a part of data randomly selected from the sensing data according to a random number generation procedure shared with the first processing unit or adding authentication information to the part of data (paragraphs: 32-42, 75-76, wherein it elaborates that an encryption module of the processing unit encrypts a randomly generated nonce to generate the encrypted data), and the first processing unit includes: a second encryption unit that generates second encryption information by encrypting a part of data randomly selected from the sensing data received from the second processing unit according to the random number generation procedure or adding authentication information to the part of data; (paragraphs: 67-71, and 78-79, wherein it discusses that the another processing unit includes an encryption module which encrypts a randomly generated nonce from the encrypted portion of data received from the processing unit). Although, KALACH deliberates about first and second portion of the encrypted data.

10. As per claim 7, KALACH and in view of LEE discloses the signal processing device wherein the first processing unit includes a first random number generation unit that generates a first random number according to the random number generation procedure, the second processing unit includes a second random number generation unit that generates a second random number according to the random number generation procedure, the first encryption unit generates the first encryption information on a basis of the first random number, and the second encryption unit generates the second encryption information on a basis of the second random number (KALACH, paragraphs: 22, 27, and 29).
11. As per claim 8, KALACH and in view of LEE discloses the signal processing device wherein the first random number generation unit generates the first random number according to the random number generation procedure by using key information and a third random number shared between the first processing unit and the second processing unit, and the second random number generation unit generates the second random number according to the random number generation procedure by using the key information and the third random number (KALACH, paragraphs: 69, and 73).
12. As per claim 9, KALACH and in view of LEE discloses the signal processing device wherein the first processing unit includes: a third random number generation unit that generates the third random number; and a communication unit that transmits the third random number to the second processing unit (KALACH, paragraphs: 21, and 40).

Citation of References
21. The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. The following references are cited but not been replied upon for this office action:
Kurian et al (US pat. app. Pub. 20210234693): discusses an encrypted dataset, a first access control measure, and instructions. The encrypted dataset includes a first encrypted block of data, encrypted using a first encryption algorithm, and a second encrypted block of data, encrypted using a second encryption algorithm stronger than the first. The first access control measure is associated with a first access control characteristic and is configured to selectively prevent access to the encrypted dataset. The instructions are configured, when executed by a processor of a device of a first user, to determine that a first characteristic of the first user matches the first access control characteristic. In response, the instructions are configured to decrypt the encrypted dataset to form a plain text dataset and provide the device of the first user access to the plain text dataset. Decrypting the encrypted dataset includes decrypting the first and second blocks of data.
YOSHINO et al (US pat. App. Pub. 20200401706): elaborates that data comparison device holds first and second encrypted data of first and second plaintext, respectively. The first plaintext is divided into a plurality of blocks and the first encrypted data is generated by executing encryption of each of the plurality of blocks and shuffling of the plurality of blocks. The second plaintext is divided into a plurality of blocks and the second encrypted data is generated by executing encryption of each of the plurality of blocks. In at least one of the first encrypted data and the second encrypted data, a plaintext value is embedded as a value indicating a magnitude comparison result, and the data comparison device compares blocks at the same position before shuffling of the first encrypted data and the second encrypted data based on the embedded value and determines a magnitude relationship between the first plaintext and the second plaintext.
