Digital watermarking is the process of hiding digital information in a carrier signal; the hidden information should, [ 2] but does not need ...
Watermark (data file) A watermark stored in a data file refers to a method for ensuring data integrity which combines aspects of data hashing and digital watermarking. Both are useful for tamper detection, though each has its own advantages and disadvantages.
In such a case, the technique of hiding the message (here, the watermark) must be robust to prevent tampering.

That is the key difference between steganography and digital watermarking.
And this is why digital watermarking, which has now been rolled out by Adobe, Microsoft, and others, is no silver bullet for the problem of deepfakes and other kinds of generative AI fraud. It is ...
