Abstract

Abstract Steganography is a technique that embeds secret information in a suitable cover file such as text, image, audio, and video in such a manner that secret information remains invisible to the outside world. The study of the literature relevant to video steganography reveals that a tradeoff exists in attaining the acceptable values of various evaluation parameters such as a higher capacity usually results in lesser robustness or imperceptibility. In this article, we propose a technique that achieves high capacity along with required robustness. The embedding capacity is increased using singular value decomposition compression. To achieve the desired robustness, we constrain the embedding of the secret message in the region of interest in the cover video file. In this manner, we also succeed in maintaining the required imperceptibility. We prefer Haar-based lifting scheme in the wavelet domain for embedding the information because of its intrinsic benefits. We have implemented our suggested technique using MATLAB. The analysis of results on the prespecified parameters of the steganography justifies the effectiveness of the proposed technique.

Highlights

  • Steganography is a technique that embeds secret information in a suitable cover file such as text, image, audio, and video in such a manner that secret information remains invisible to the outside world

  • A robust image watermarking scheme is proposed by the author in an earlier study [7] by combining the lifting wavelet scheme and Singular value decomposition (SVD), which is used to hide the secret information

  • Transforming the image in the frequency domain increases calculation difficulty in these techniques. As this technique works on a floating-point number, the reconstruction of the watermark is difficult. To overcome all these problems, a stable, high-capacity video steganography is proposed that collaborates the face detection and SVD techniques in the wavelet domain

Summary

Introduction

Abstract: Steganography is a technique that embeds secret information in a suitable cover file such as text, image, audio, and video in such a manner that secret information remains invisible to the outside world. A robust image watermarking scheme is proposed by the author in an earlier study [7] by combining the lifting wavelet scheme and SVD, which is used to hide the secret information. Video and audio can be used as a cover file as proposed in an earlier study [9] to obtain high embedding capacity. Authors in an earlier study [10] proposed an integer wavelet transform technique for embedding information in HH coefficients along with cropping in 8 × 8 block on wrap file. The researchers developed a technique to present a high-level security organization by implementing and designing a multilevel steganography system to embed information in a color video file [14] This scheme was executed in the frequency domain, using a wavelet transform. SVD was used in the planned system for providing more robustness
