Abstract
A digital watermarking method comprises: generating a base watermark comprising a two-dimensional pixel array partitioned into image patches from a watermark data set by embedding the watermark data set into the image patches of the base watermark according to patch positional indices; and embedding the base watermark into the digital file by circular padding.
Claims20
A method of digitally watermarking a digital file, the method comprising:
- generating a base watermark comprising a two-dimensional pixel array partitioned into image patches from a watermark data set by embedding the watermark data set into the image patches of the base watermark according to patch positional indices;
- and
- embedding the base watermark into the digital file by circular padding.
A digital watermarking system comprising:
- a processor and a data storage device storing computer program instructions operable to cause the processor to:
- generate a base watermark comprising a two-dimensional pixel array partitioned into image patches from a watermark data set by embedding the watermark data set into the image patches of the base watermark according to patch positional indices;
- and
- embed the base watermark into the digital file by circular padding.
