Authenticating metadata and embedding metadata in watermarks of media signals |
摘要 |
Auxiliary data is associated with an image and a metadata router stores links and metadata servers associated with the links. When a steganographically embedded link is extracted from an image, said link is used at the metadata router to locate a metadata server associated with the link, wherein that metadata server stores auxiliary data associated with the media signal; and the link to the metadata server that stores the auxiliary data associated with the media signal is forwarded from the metadata router. |
