“…It can be observed that the proposed scheme obviously outperforms the other four in terms of the embedding capacity and image quality. To be more detailed, the embedding capacity of the proposed scheme (i.e., 2.5 bpp) is much higher than that of [23] (i.e., 1.5 bpp), just with a slight decrease of PSNR. The image quality of the proposed scheme is better than that of [24,25], even with a higher embedding capacity.…”

Data hiding is a technology that embeds data into a cover carrier in an imperceptible way while still allowing the hidden data to be extracted accurately from the stego-carrier, which is one important branch of computer science and has drawn attention of scholars in the last decade. Turtle shell-based (TSB) schemes have become popular in recent years due to their higher embedding capacity (EC) and better visual quality of the stego-image than most of the none magic matrices based (MMB) schemes. This paper proposes a two-layer turtle shell matrix-based (TTSMB) scheme for data hiding, in which an extra attribute presented by a 4-ary digit is assigned to each element of the turtle shell matrix with symmetrical distribution. Therefore, compared with the original TSB scheme, two more bits are embedded into each pixel pair to obtain a higher EC up to 2.5 bits per pixel (bpp). The experimental results reveal that under the condition of the same visual quality, the EC of the proposed scheme outperforms state-of-the-art data hiding schemes.

Steganography used for secure transmission of secret message. Message transmitted over the internet facing malicious attack. So, steganography is needed for secure transmission of secret message. There are two methods which are used for secure transmission. The first method cryptography, secret message which needs to be transmitted over the internet is encrypted using encryption key and sent over the communication channel and at the receiver side only right person with valid key can retrieve the secret message. The second method is steganography, in this method secret message hidden inside the cover media like image, audio, video etc. In this paper, we have presented video steganography using Zero Order Hold(ZOH) technique. Zero Order Hold is basically zooming method, it is used for image zooming. By applying ZOH method, secret information embedded in the cover video.

“…Also, it outperforms EMD, Chang et al's scheme [8] and Hong et al's scheme [9] in better image quality under the same embedding capacity. Later, Liu et al [12] improved Chang et al's scheme [11] by constructing a location table from the turtle shell-based reference matrix to guide the modification of cover pixel pairs. This scheme achieves very good image quality above 45 dB and is better than Chang et al's scheme [11] with higher embedding capacity.…”

“…Experimental results showed that EMD-2 is superior to EMD in larger payloads with similar image distortions. In 2014, Chang et al [11] proposed a novel data hiding scheme originating from EMD and turtle shell structure. The binary secret stream can be embedded directly in such a way that three secret bits are embedded in a pair of consecutive cover pixels with the guidance of a reference matrix based on turtle shells.…”

“…In recent years, many data hiding schemes that are inspired by the concept of EMD have been proposed to increase the embedding capacity [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Lee et al's scheme [7] employed a pixel segmentation strategy to provide a larger payload than that of EMD, but this suffers from worse image quality.…”

Data hiding is an efficient technique that conceals secret data into a digital medium. In 2006, Zhang and Wang proposed a data hiding scheme called exploiting modification direction (EMD) which has become a milestone in the field of data hiding. In recent years, many EMD-type data hiding schemes have been developed, but their embedding capacity remains restricted. In this paper, a novel data hiding scheme based on the combination of Chinese remainder theorem (CRT) and a new extraction function is proposed. By the proposed scheme, the cover image is divided into non-overlapping pixel groups for embedding to increase the embedding capacity. Experimental results show that the embedding capacity of the proposed scheme is significantly higher (greater than 2.5 bpp) than previously proposed schemes while ensuring very good visual quality of the stego image. In addition, security analysis is given to show that the proposed scheme can resist visual attack.
