Abstract
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.
