Watermarking and fingerprinting algorithms

The C2PA specification refers to watermarking and content fingerprinting as soft bindings, which can be used to find digital content, even if the underlying bits differ. The C2PA specification requires that soft bindings be generated using one of the algorithms approved by the C2PA Technical Working Group.
