| 摘要 | A system and method for securing media content are provided. A method for distributing security media content includes embedding a marking payload into media content, thereby producing embedded media content, applying a transform to the embedded media content, thereby producing secured media content, and distributing the secured media content. The marking payload is embedded based on perceptual information regarding the media content. | ||

| 主权项 | 1. A method for distributing security media content, the method comprising: determining an embedding strength in accordance with media content, the determining comprising: computing a spatial mask;computing a temporal mask;selecting a smaller of the spatial mask or the temporal mask, thereby producing a selected mask;restricting the selected mask to reside within a range; andsetting the restricted selected mask as the embedding strength; embedding a marking payload into the media content in accordance with the embedding strength, thereby producing embedded media content; applying a transform to the embedded media content, thereby producing secured media content; and distributing the secured media content. | ||
