Metrics details. The aim of this paper is to present multiobjective evolutionary optimizer MEO based highly secured and strongly robust image watermarking technique using discrete wavelet transform DWT and singular value decomposition SVD. Many researchers have failed to achieve optimization of perceptual quality and robustness with high capacity watermark embedding. Strong security is implemented through eight different security levels including watermark scrambling by Fibonacci-Lucas transformation FLT. Haar wavelet is selected for DWT decomposition to compare practical performance of wavelets from different wavelet families.

In this paper, a new Steganography technique is presented, implemented and analyzed. The proposed method hides the secret message based on searching about the identical bits between the secret messages and image pixels values. Save to Library. Create Alert. Launch Research Feed.
The first recorded use of the term was in by Johannes Trithemius in his Steganographia , a treatise on cryptography and steganography, disguised as a book on magic. Generally, the hidden messages appear to be or to be part of something else: images, articles, shopping lists, or some other cover text. For example, the hidden message may be in invisible ink between the visible lines of a private letter. Some implementations of steganography that lack a shared secret are forms of security through obscurity , and key-dependent steganographic schemes adhere to Kerckhoffs's principle. The advantage of steganography over cryptography alone is that the intended secret message does not attract attention to itself as an object of scrutiny.
In copyright- and privacy-protected image trading systems, the image sent to the trusted third party TTP is visually encrypted, and the image is traditionally unrecognizable. The image, however, is suspicious and has possibility to be attacked. Image steganography then becomes more interesting than image encryption for this application, however, applying image steganography instead of image encryption degrades the fingerprint extraction performance. In addition, the CP is allowed to directly contact with the consumer in the conventional systems. This paper then proposes a new copyright- and privacy-protected image trading system with a novel steganography-based visual encryption scheme, where the scheme protects a commercial image much more securely by generating a recognizable image instead of a suspicious encrypted image. By replacing amplitude components of a dummy image by those of a commercial image, the output image looks like a degraded dummy image instead of the commercial image, while it contains some details of the commercial image, i.
