Detection of perturbed quantization (PQ) steganography based on empirical matrix

Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...

A Novel Data Hiding Scheme for Binary Images

this paper presents a new scheme for hiding a secret message in binary images. Given m×n cover image block, the new scheme can conceal as many as ⌊ ⌋ bits of data in block, by changing at most one bit in the block. The hiding ability of the new scheme is the same as Chang et al.'s scheme and higher than Tseng et al.'s scheme. Additionally, the security of the new scheme is higher than the two a...

Reversible Data Hiding and Reversible Authentication Watermarking for Binary Images

Data hiding is a technique used to embed a sequence of bits in a host image with small visual deterioration and the means to extract it afterwards. Reversible data hiding allows, in addition, recovering the original cover-image exactly. Several reversible data hiding techniques have been developed but none of them seems to be appropriate for binary images. This paper proposes a reversible data ...

High Capacity Data Hiding Scheme for DCT-based Images

To enhance the hiding capacity of DCT-based images, in this paper we propose a new data hiding scheme based on a notation transformation concept. Without considering the reversibility function, experimental results confirm that the hiding capacity provided by our designed data hiding strategy is not only higher than that provided by the Iwata et al.’s, Chang et al.’s and Lin et al.’s schemes bu...

A High-Capacity Lossless Data Hiding Scheme for Binary Images

Many previous binary image lossless data hiding schemes often cause serious perceptible distortion and have poor visual quality of stego-images. To obtain better invisibility and higher hiding capacity, a novel reversible data hiding scheme for binary images is proposed by combining pattern substitution and human visual perception. Firstly, an improved binary image boundary detection method is ...
