Colour Guided Colour Image Steganography
Information security has become a cause of concern because of the electronic eavesdropping. Capacity, robustness and invisibility are important parameters in information hiding and are quite difficult to achieve in a single algorithm. This paper proposes a novel steganography technique for digital color image which achieves the purported targets. The professed methodology employs a complete ran...
متن کاملAn RGB colour image steganography scheme using overlapping block-based pixel-value differencing
This paper presents a steganographic scheme based on the RGB colour cover image. The secret message bits are embedded into each colour pixel sequentially by the pixel-value differencing (PVD) technique. PVD basically works on two consecutive non-overlapping components; as a result, the straightforward conventional PVD technique is not applicable to embed the secret message bits into a colour pi...
متن کاملSecure RGB Image Steganography from Pixel Indicator to Triple Algorithm-An Incremental Growth
Steganography is the art of hiding the fact that communication is taking place, by hiding information in other information. In this paper we have investigate two methods of RGB image steganography one is pixel indicator technique and other is triple-A algorithem.They uses the same principle of LSB, where the secret is hidden in the least significant bits of the pixels, with more randomization i...
متن کاملColour Image Steganography Based on Pixel Value Differencing in Spatial Domain
In a color image every pixel value composed of red, green and blue component and each of which ranges from 0 to 255 in case of 8-bit representation. In this paper, we have used pixel value differencing (PVD) method for secret data embedding in each of the component of a pixel in a color image. But when we use pixel-value differencing (PVD) method as image steganographic scheme, the pixel values...
متن کاملMosaic Image Steganography Based Colour Transformation for Enhanced Security
A new secure image transmission method is proposed, Here it uses the technique of Steganography and Cryptography, Which transforms automatically a given large-volume secret image into a so-called secret-fragment-visible mosaic image of the same size. The mosaic image which looks similar to an arbitrarily selected target image and may be used as a disguise of the secret image is yielded by divid...
