Core watermark blind detection method based on zero-knowledge proof protocol

The invention discloses a core watermark blind detection method based on a zero-knowledge proof protocol. The method comprises the following steps that the zero-knowledge proof protocol is preprocessed; signature information containing a zero-knowledge watermark is embedded in a core bit file through a watermark embedder, and a bit flow file containing the watermark is obtained; on the basis of a zero-knowledge proof protocol detection method, a watermark extractor extracts the watermark information from the bit file containing the watermark; an Hibert curve is subjected to integral scrambling and partitioned scrambling processing through introduction of variable factors; and through initialization, inquiry, response and verification, a buyer can detect the watermark copyright information of an owner from a configuration file of a kernel. According to the method, the zero-knowledge core watermark information is fused in an existing public key encryption scheme, the defects that public watermark evidence obtained on public places is not considered in other core watermark schemes are overcome, and the method has good transparence, safety and robustness.
