DEVICE FOR GENERATING WATERMARK METADATA, ASSOCIATED DEVICE FOR EMBEDDING WATERMARK |
摘要 |
A device for generating metadata associated with a content intended to be watermarked with an identifier stored in a device for embedding a watermark is disclosed. The device for generating metadata comprises a processor configured to generate metadata. The metadata comprises (i) an instruction for deriving a current payload bit from the identifier wherein the current payload bit is determined from a lookup index wherein the instruction for deriving a current payload bit indicates to which position in the identifier corresponds the current payload bit, or from a XOR function applied to a plurality of bits of the identifier, wherein the instruction for deriving a current payload bit comprises a binary mask indicating which bits in the identifier corresponds to XORed bits.
