The present disclosure provides systems and methods for authenticating photographic data. In one embodiment, a method comprises providing an image authentication application for use on a client device, the application configured to control image capture and transmission; receiving an image data file from the application at the authentication server comprising a photographic image captured by the application and metadata associated therewith; applying a watermark to the photographic image to create a watermarked image; applying date and time information to the tagged image; applying location information to the tagged image; creating a web address associated with the image data file; uploading the photographic image, the tagged image, or both to the web address; and transmitting an authenticated image file to the client device, the authenticated image file comprising one or more of: the watermarked image, the photographic image, the date and time information, geographic information, and the web address.

Approaches for creating video on demand (VOD) assets with a VOD watermark. For a digital stream yet to be broadcast, a duplicate version of an accompanying audio stream comprised within the digital stream is created. A video on demand (VOD) watermark is inserted into or affixed within the duplicate version of the accompanying audio stream. Thereafter, the digital broadcast stream which comprises the original audio stream and the duplicate version is transmitted to an integrated receiver-decoder. The integrated receiver-decoder creates a broadcast version of the digital broadcast stream which comprises a broadcast watermark and a video on demand (VOD) version of the digital broadcast stream which comprises a VOD watermark. The integrated receiver-decoder may align the broadcast video with the VOD watermarked audio to ensure proper local storage and subsequent VOD distribution.
