Spread spectrum image steganography
IEEE Transactions on Image Processing, 1999In this paper, we present a new method of digital steganography, entitled spread spectrum image steganography (SSIS). Steganography, which means "covered writing" in Greek, is the science of communicating in a hidden manner. Following a discussion of steganographic communication theory and review of existing techniques, the new method, SSIS, is ...

Image Steganography and Chrominance Components
2010 10th IEEE International Conference on Computer and Information Technology, 2010Digital images are the most common cover files used for steganography. This paper investigates the pros and cons of colour and grayscale versions of images when used as steganography covers. Therefore, it comparatively evaluates the performance of both grayscale and colour versions of a given cover image when they are used with a given steganography ...

Adaptive Batch Size Image Merging Steganography and Quantized Gaussian Image Steganography
IEEE Transactions on Information Forensics and Security, 2020In digital image steganography, the statistical model of an image is essential for hiding data in less detectable regions and achieving better security. This has been addressed in the literature where different cost-based and statistical model-based approaches were proposed.

Steganography based on image morphing
2013 International Joint Conference on Awareness Science and Technology & Ubi-Media Computing (iCAST 2013 & UMEDIA 2013), 2013Nowadays, large scale data-centers have been built around the world, and cloud computing is becoming more and more popular. With the help of cloud computing, users can access their data and obtain different services anywhere and anytime. However, many people and companies still hesitate to use cloud based services because of the information security ...

Image Processing with Android Steganography
2015Digital Steganography is a technique that provides confidential communications between two parties via Internet and Mobile Networks. This paper proposes a new solution of digital steganography based on Android operating system. The proposed method uses an improved LSB technique by a random selection function and has as cover BMP files. Image processing

Steganography in JPEG2000 compressed images
IEEE Transactions on Consumer Electronics, 2003Information hiding in JPEG2000 compressed images is investigated in this research. The challenges of covert communication in this state-of-the-art image codec are analyzed and a steganographic scheme is then proposed to reliably embed high-volume data into the JPEG2000 bit-stream.

Image Steganography Optimization Technique
2012This paper presents a novel steganography technique which combines Discrete Cosine Transform (DCT) and Least Significant Bit (LSB). The objective is to maximize the capacity and invisibility of the secret image with minimal modification to the cover image (at most k-bits per block). The secret image is transformed to frequency domain using DCT.

IIS: Implicit Image Steganography
2014In steganography secrets are imposed inside the cover medium either by replacing bits in the spatial domain or changing the frequency domain. Instead the proposed Implicit Image Steganography (IIS) scheme does not alter or replace bits in the original cover image for hiding information.

Fractal based image steganography
1996This paper describes a new and novel steganographic method for inserting secret information into image files. The method uses fractal image compression techniques in the production of these steganographic image files. The method allows a user to specify a visual key when hiding the secret information.
