An encoding apparatus partitions a digital image into multiple regions for subsequent encoding. A first encryption code is associated with a first region, a second encryption code is associated with a second region and the first code, and a third code is associated with the first code, the second code and a third region. An authentication apparatus authenticates the digital image in an inverse process.

A user can wear a device which emits a visual and/or audible output. The output changes over time. A system is capable of predicting the output. Thus, the system can analyze a video and determine, based on observed output of the device, whether the video has been modified. The output can be particularly difficult for humans to modify, detect, understand, or recreate, further impeding attempts to disguise edits to the video.

A method, computer program product, and system for generating and embedding a watermark in digital video frame include a processor obtaining a request to generate a watermark and embed the watermark in a digital video frame captured by a first monitor. Based on obtaining the request, the processor fetches from one or more pre-defined regions of a memory resource, digital video data captured by at least two monitors, where a timestamp of the digital video data is equal to a timestamp of the digital video frame. The processor generates a watermark from the digital video data by calculating a binary result of the digital video data. The processor embeds the watermark (binary result) in the digital video frame.

System, apparatus, device, method and/or computer program product are disclosed for detecting the authenticity of an image file transferred from a device to a server based on an image authenticity detection configuration determined by a server application. A device application is operated by a device, and a server application is operated by a server. The device application sends, to the server application, user data, device data, or environment data. The server application determines an image authenticity detection configuration to indicate one or more parameters to be used by the device to generate a first image file, and authorized changes to be made to the first image file to generate a second image file. The device application sends the second image file to the server application. The server application detects whether the received second image file contains changes matching authorized changes indicated by the image authenticity detection configuration.

A recording device, system, and method for generating digital content in which its content can be authenticated. The recording devices includes hardware that captures video data and digitally signs portions of the video data to generate a plurality of digital signatures. The digital signatures can be used to authenticate the video data in a manner that modification of a portion of the video data invalidates a respective digital signature. In addition, the digital signatures can be further used to authenticate a position of the portion of the video data relative to at least one other portion of the video data.

Methods and apparatuses for watermark embedding and extracting are provided. A method for watermark embedding includes obtaining a carrier object and watermark information to be embedded in the carrier object; generating at least one encoding region including the watermark information according to the watermark information, the at least one encoding region including a plurality of template lattices; obtaining a watermark image according to the at least one encoding region; and embedding the watermark image in the carrier object.

A video stream management system includes a video controller that live renders video. Moreover, the video stream management system also includes a display that is communicatively coupled to the video controller and displays a primary video feed that includes the live rendered video. The video controller, the display, or a combination thereof, embeds a pixel pattern in the primary video feed. Additionally, the video feed management system monitors one or more displayed images on the display to identify an error in the primary video feed.
