Abstract EN
Data hiding is a technique that hides the existence of secret data from malicious attackers.
In this paper, we propose a new data-hiding scheme using multidirectional pixel-value differencing, which can embed secret data in two directions or three directions on colour images.
The cover colour image is divided into nonoverlapping blocks, and the pixels of each block are decomposed into R, G, and B channels.
The pixels of each block perform regrouping, and then the minimum pixel value within each block is selected.
The secret data can be embedded into two directions or three directions based on the minimum pixel value by using the difference value for the block.
The pixel pairs with the embedded secret data are put separately into two stego images for secret data extraction on receiver sides.
In the extraction process, the secret data can be extracted using the difference value of the two stego images.
Experimental results show that the proposed scheme has the highest embedding capacity when the secret data are embedded into three directions.
Experimental results also show that the proposed scheme has a high embedding capacity while maintaining the degree of distortion that cannot be perceived by human vision system for two directions.
