This paper presents a novel watermarking algorithm based on a newly developed transform known as conjugate symmetric sequency-ordered complex Hadamard transform (CSSCHT). The algorithm is performed in the sequency domain where the phases of the CS-SCHT coefficients are altered to convey the watermar...
