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 § 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.
Claim(s) 1-7, 9-15 and 17-23 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Chang et al (US PG Pub No. 2015/0082030).
Regarding claims 1, 9 and 17, Chang et al a method (Abstract), comprising:
generating a key pair comprising a private key and a public key (i.e. user 40 produces a public key and a private key based on asymmetric cryptography) (Para. 0015); storing at least the private key on a data processing device of a user (Para. 15) and storing only the public key on an internet of things (loT) camera [10,30] associated with an account of a user (i.e. public key is sent to the CVR manager 10 via the Internet while the private key is kept by the user 40) (Figure 2; Abstract, Para. 15);
in response to an event (Para. 0016), the loT camera to perform the operations of:
generating a temporary data encryption key (DEK) (Para. 0017);
encrypting video captured by the camera using the DEK to generated encrypted video blocks (Para. 17-18);
encrypting the DEK using the public key to generate an encrypted DEK (Para. 18-19); and
transmitting the encrypted video blocks and the encrypted DEK to a video storage service (Abstract, Figures 1-2; Para. 19).
Claims 2, 10 and 18 are rejected wherein receiving an indication to play back the encrypted video blocks on the data processing device (Para. 20); downloading or streaming the encrypted video blocks and the encrypted DEK from the storage service (Para. 20); using the private key to decrypt the encrypted DEK to produce the DEK (i.e. user 40 then uses the private key to decrypt the encrypted text file of the random key and therefore obtains the random key) (Para. 20); using the DEK to decrypt the encrypted video blocks for rendering on the data processing device (i.e. the user 40 uses the random key to decrypt the encrypted text file of the video footage and therefore obtains the plaintext file of the video footage) (Para. 20-21).
Claims 3, 11 and 19 are rejected wherein the data processing device generates the key pair in response to an loT app executed on the data processing device, and shares the public key with the loT camera (Para. 04-5, 15).
Claims 4, 12 and 20 are rejected wherein the loT app initially associates the loT camera with an account of the user on an loT service and establishes a secure communication channel with the loT camera to provide the public key to the loT camera (Figure 1; Para. 14-15).
Claims 5, 13 and 21 are rejected wherein the event comprises a first event, the DEK comprises a first DEK, the encrypted DEK comprises a first encrypted DEK, the video comprises a first video, and the encrypted video blocks comprise first encrypted video blocks, the method further comprising: in response to a second event, the loT camera to perform the operations of: generating a second temporary data encryption key (DEK);encrypting second video captured by the loT camera using the second DEK to generated second encrypted video blocks; encrypting the second DEK using the public key to generate a second encrypted DEK; and transmitting the second encrypted video blocks and the second encrypted DEK to a video storage service (The reference teaches per footage file basis, wherein each video segment generates a separate random key meeting per event DEK generation of claim 5) (Figures 1-2; Abstract, Para. 14-17).
Claims 6, 14 and 22 are rejected wherein the video storage service is to perform the operations of: associating the first encrypted DEK with the first encrypted video blocks and associating the second encrypted DEK with the second encrypted video blocks; responsive to requests from the data processing device, transmitting either the first encrypted DEK with the first encrypted video blocks or transmitting the second encrypted DEK with the second encrypted video blocks to the data processing device (Para. 19-21).
Claims 7, 15 and 23 are rejected wherein the video storage service comprises: an loT service operated by the provider of the loT camera, or a third party storage service used by the loT service to store encrypted video blocks captured by the loT camera (Abstract, Para. 04-5, 14-17).
Claim Rejections - 35 USC § 103
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.
Claim(s) 8, 16 and 24 is/are rejected under 35 U.S.C. 103 as being unpatentable over Chang et al, in view of Mysore et al (US PG Pub No. 2023/0362483).
Regarding claims 8, 16 and 24, Chang et al teaches generating a second data encryption key (DEK) (Para. 17); encrypting the video stream using the second DEK to generated second encrypted video blocks (Para. 17-18); encrypting the second DEK using the public key to generate a second encrypted DEK (Para. 18-19); and transmitting the second encrypted video blocks to the video storage service, wherein the video storage service is to associate the second encrypted video blocks with the second encrypted DEK (The reference teaches per footage file basis, wherein each video segment generates a separate random key meeting per event DEK generation of claim 8) (Abstract, Fig. 1-2; Para. 19).
The reference is unclear with respect to receiving, by the loT camera, an indication that a live video stream is to be sent to the data processing device and responsively forwarding the live video stream captured by the loT camera to the data processing device; wherein in response to receiving the live video stream, the data processing device is to perform operations, comprising: rendering the live video stream for viewing by the user.
In similar field of endeavor, Mysore et al teaches receiving, by the loT camera, an indication that a live video stream is to be sent to the data processing device (the camera device determines (920) a category (e.g., category “A”) of the event (e.g., utilizing characterization module 456 in conjunction with category information 468 and/or characterization data 470) (Para. 232) and responsively forwarding the live video stream captured by the loT camera to the data processing device (i.e. streams (930) live video to the remote computer) (Para. 232); wherein in response to receiving the live video stream, the data processing device is to perform operations, comprising: rendering the live video stream for viewing by the user (Figures 9A-B; Abstract, Para. 153, 232). Therefore, it would have been obvious to one of ordinary skill in the art to modify the reference before the effectively filing date of the claimed invention for the purpose of characterizing motion to manage power on camera devices and alerting users.
