Yes, cloud on-demand video can have different watermarks for different video viewers. This is typically achieved through dynamic watermarking technology, which embeds customizable watermarks (e.g., user ID, email, or timestamp) into the video stream in real time based on viewer identity or other parameters.
For example, a video streaming platform might use dynamic watermarking to deter piracy by displaying a unique watermark (like the viewer's registered email) on the video for each user. This ensures traceability if the content is leaked.
In the cloud industry, Tencent Cloud offers Media Services with features like Dynamic Watermarking, allowing businesses to customize watermarks per viewer. This is useful for platforms like online education, enterprise training, or premium video content distribution.
