actually, I am trying to do digital watermarking. can you please giv me some hints of algos which i can use to do watermaking on numbers ? like i have array of numbers, then i want to water mark them with some kind of algo and also want to save that watermark which i will get so as to verify it in future.
P.S I am asking for any code here, i am just asking for hints of ALGOS, as i am novice in watermaking. thanks in advance.
