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.

An electronic device includes a camera assembly configured to capture an image and to process the image to create an image file. The electronic device further includes a communications interface, and a processor configured to generate digital ledger data comprising a smart contract providing rights to use or access the image based on a condition being satisfied, and image rights management information. The processor is further configured to transmit the digital ledger data using the communications interface, to a digital ledger network, and embed a pointer or link as a portion of data included within the image file. The pointer or link provides a location to access the digital ledger data.

A moving image coding apparatus adapted to code moving images including time-continuous frames is provided. A moving image coding unit outputs a coded bitstream in which the moving images are coded. A position information generation unit generates position information in a frame, based on time-continuity information indicating time continuity of the frames. A coded information acquisition unit acquires coded information on the moving images, based on the position information. An inspection information generation unit generates inspection information from the coded information. A multiplexing unit multiplexes the bitstream and the inspection information.

A configuration capable of recording MMT format data on a medium as BDAV format data and performing copy control according to the original copy control information is achieved. The MMT format data, for which copy control information is set, is input and recorded on an information recording medium as BDAV format data. As record data, (a) a stream file including a packet string in which the MMT format data is stored, and (b) copy control information corresponding to the stream file, in which the copy control information corresponding to the MMT format data is reflected, are generated and recorded as an additional header of a packet included in the stream file or as another file.

In aspects of recorded content managed for restricted screen recording, a wireless device displays digital image content, and a screen recording session captures the digital image content and audio data. The wireless device implements a content control module that determines a device application restricts the screen recording session from capturing the media content. The content control module can then pause the screen recording session for a time duration that the device application restricts the screen recording session, and then resume the screen recording session after a determination that the screen recording session is no longer being restricted. As an alternative to pausing the screen recording session, the content control module can add a start delimiter to indicate a beginning section of the screen recording session being restricted by the device application, and add an end delimiter to indicate an end section of the screen recording session being restricted.

A video displaying method. The method includes applying a first frequency modulation in time domain on an original video thereby obtaining a first modulated video; applying a second frequency modulation in spatial domain on the first modulated video thereby obtaining a second modulated video including a first invisible-light image; and displaying the second modulating video with a corresponding frame rate. A time-domain frequency of the first invisible-light image is in a first range unrecognizable by a naked eye and recognizable by a video recorder. A spatial-domain frequency of the first invisible-light image is in a second range unrecognizable by the naked eye and recognizable by a video recorder.
