Adaptive Reversible Data Hiding in Frequency Domain via Integer-to-Integer Transform

Abstract—This paper proposes an adaptive reversible data hiding algorithm for images, which embeds significant informa-tion in frequency domain based on integer-to-integer transform. The embedding method is realized by modifying state-of-the-art one according to integer-to-integer transformed coefficients. It overcomes a problem where the conventional method often gen-erates particular artifacts. The simulation results show that our proposed algorithm outperforms the conventional one about the visual quality of embedded images, objectively and perceptually, while keeping embedding capacity. I
