Steganography is one of the popular methods in information hiding that allows people to
communicate secretly. The main advantage of image steganography is that the image within …

Obscuring the important message before disseminating become obligatory. In a traditional
(n, k) threshold visual secret sharing (VSS), size of the reassembled secret is more than the …

This brief presents three space-frequency (SF) precoded orthogonal frequency division
multiplexing (OFDM) systems to combat inter-carrier interference in mobile fading channels …

The proposed algorithm takes an initiative to justify strong ownership claims by blending
visual cryptography with steganography, which is quite different from a conventional …

This paper presents precoded space-time-frequency (STF) 4× 1 and 4× 2 orthogonal
frequency-division multiplexing (OFDM) systems in frequency-selective fading channels …

In this paper, orthogonal transforms with their wavelet transforms and Hybrid wavelet
transforms are proposed to be used for image steganography using Kekre, Walsh and Sine …

Steganography is defined as the process of hiding information in a multimedia carrier. In this
paper, video is taken as a carrier to hide information. To achieve Undetectability and …

Security has become very important with increasing number of attacks made on digital
content in today's internet savvy world. The sharing of information in secret way has become …

In this paper, performance of orthogonal transforms with their wavelet transforms and Hybrid
wavelet transforms are compared for image steganography. Here, wavelet transforms and …

with the advancement of technology, the threats dealt by user have increased exponentially.
Hence security of data is required during storage and transmission of data. Image …
