This application discloses a video recording apparatus and a video recording method. The video recording apparatus includes a first demultiplexer, configured to: separate program information, audio data, and video data from a transport stream; a marker, configured to: mark the separated audio data and the separated video data, and transmit a mixed stream to an encryption processor, where the mixed stream includes the program information, the marked audio data, and the marked video data; and the encryption processor, configured to: identify the marked audio data and the marked video data in the mixed stream, encrypt the identified audio data and the identified video data to obtain encrypted audio data and encrypted video data, and transmit the encrypted audio data, the encrypted video data, and the program information to a memory in a rich execution environment REE for storage, so as to implement video recording.

An electronic device is provided. The electronic device includes a controller, configured to receive an input image signal captured by a camera device, perform a codec process on the input image signal to generate a processed file. The controller is further configured to perform privacy detection on the input image signal or the processed file. In response to the input image signal or the processed file being detected to include privacy information, the controller is further configured to encrypt the processed file to generate an encrypted file.

A digital information recording apparatus includes a recording circuit for recording information of a retention period included in the digital information and indicating a period for permitting the digital information to be held in the recording medium, starting with a time at which the digital information is recorded on the recording medium; and information of a playback permission period included in the digital information and indicating a period for permitting the digital information to be played back starting with a time at which the information is reproduced initially following recording of the digital information on the recording medium, permitting temporary recording or copying for the information permitted for “copy never” or “copy one generation.”

An enclosed security system, including a system container to store at least one item therein, a connection panel removably disposed within at least a portion of an interior of the system container to receive a connection from at least one security camera, and a network video recorder disposed within at least a portion of the interior of the system container to retrieve video data from the at least one security camera.

An encrypting and decrypting method applied to a system including at least one camera device and a hard disk video decoder includes: transmitting a handshake signal to the camera device which supports an encryption function and has selected the encryption function, wherein the handshake signal includes first identifier information uniquely corresponding to a chip of the hard disk video recorder; receiving the handshake signal; generating a key according to the first identifier information of the hard disk video recorder in the handshake signal and second identifier information uniquely corresponding to a chip of the camera device; encrypting an audio/video file recorded by the camera device according to the key to generate an encrypted audio/video file bitstream; and receiving and decrypting the encrypted audio/video file bitstream.

A method for cooperatively collecting video data from driving recorders includes steps of: by a driving recorder serving as a requesting device, broadcasting a video request; by another driving recorder serving as a cooperative device, generating a video file in response to receipt of the video request, encrypting the video file to result in an encrypted file, and transmitting the encrypted file to a video file server; by the video file server, decrypting the encrypted file to result in the video file, storing the video file, and sending a success notification of video data collection to a user device based on contact information contained in pre-stored registration data.

A media client device, including a memory and capable of processing Quadrature Amplitude Modulation (QAM) channels and IP channels, may receive a recording request to record content on an Internet Protocol (IP) channel. The media client device may provide, to a first device, a source Universal Resource Locator (URL) corresponding to the content, and receive, from the first device, encrypted content (e.g., an encrypted version of the content). The media client device may store, in the memory, the encrypted content, and provide, to a second device, information regarding the encrypted content to permit the second device to generate and store a license and a key. The media client device may receive a playback request to play the content, and obtain, from the second device, the license and the key. The media client device may decrypt, using the license and the key, the stored, encrypted content to obtain the content.

An electronic device is provided. The electronic device includes a controller, configured to receive an input image signal captured by a camera device, perform a codec process on the input image signal to generate a processed file. The controller is further configured to perform privacy detection on the input image signal or the processed file. In response to the input image signal or the processed file being detected to include privacy information, the controller is further configured to encrypt the processed file to generate an encrypted file.

Apparatus and methods for encrypting captured media. In one embodiment, the method includes capturing media data via use of a lens of an image capture apparatus; obtaining a number used only once (NONCE) value from the captured media data; obtaining an encryption key for use in encryption of the captured media data; using the obtained NONCE value and the obtained encryption key for encrypting the captured media data; and storing the encrypted media data. In some variants, the media is encrypted prior to storage, thereby obviating any instances in which the captured media data resides in a wholly unencrypted instance. Apparatus and methods for decrypting encrypted captured media are also disclosed.

A digital focal plane array includes an all-digital readout integrated circuit in combination with a detector array. The readout circuit includes unit cell electronics, orthogonal transfer structures, and data handling structures. The unit cell electronics include an analog to digital converter. Orthogonal transfer structures enable the orthogonal transfer of data among the unit cells. Data handling structures may be configured to operate the digital focal plane array as a data encryptor/decipherer. Data encrypted and deciphered by the digital focal plane array need not be image data.
