Steganography is a study to hide secret message in multimedia cover which will be transmitted through the Internet. The cover carriers can be image, video, sound or text data. In this paper, a novel scheme is proposed to hide data in 8-bits gray-scale cover image based on a 256times256 secret reference matrix (SRM) which was constructed by using a 3times3 table with unrepeated digits from 0~8. Experimental...
In this paper, we propose a simple reversible data hiding method in spatial domain for digital images by exploiting the correlation characteristic of neighboring pixels in natural images. The proposed method embeds several secret bits into a block of two consecutive cover pixels whose values are equal. The experimental results show that the proposed method achieves very good visual quality at low...
Secret information protection has received increasing attention from the information technology community. Proposing a novel information hiding scheme to effectively conceal secret information in various applications is encouraged. In this paper, we proposed a novel reversible information hiding scheme by embedding secret information into dual image. The proposed scheme first converts the secret bit...
With the ever-increasing wireless multicast data applications recently, considerable efforts have focused on the design of self-adaptive flow control schemes for wireless multicast service. This paper proposes a novel and efficient distributed flow control scheme for wireless multi-rate multicast (MR-M), based on the well-known proportional integral and derivative (PID) controllers. The PID controller...
In this paper, a novel data hiding method employing reduplicating embedding is proposed. This method uses seven most significant bits to embed two secret digits and sets the least significant bit as an indicator. Therefore, two secret digits can be embedded into one pixel-group without using the original cover-image and extra data. Because of repeating to embed secret data, our method can provide...
In this paper, we share and embed secrets with images using secret expansion in such a way that secrets are easily reconstructable from the two shares, but getting any one share reveals no information about the secrets. After the reconstruction scheme, the original image can be completely recovered. The proposed scheme is simple without using any data compression and without any extra information.
Steganography is the science of secret message delivery using cover media. A digital image is a flexible medium used to carry a secret message because the slight modification of a cover image is hard to distinguish by human eyes. The proposed method is inspired from Zhang and Wang's method and Sudoku solutions. A selected Sudoku solution is used to guide cover pixels' modification in order to imply...
