“…There have been numerous research efforts dedicated to the analysis of past and current steganographic methods because of the importance of securing important data or information [1], [2], [5], [6], [7]. The most popular transform hiding steganography techniques are based on the discrete Fourier transform (DFT), the discrete cosine transform (DCT), the discrete wavelet transform (DWT), the singular value decomposition (SVD), the discrete Hadamard transform (DHT) [1] and the Integer Lifting Wavelet Transform (IntLWT) [5].…”

The magnitude of the growth in the Internet combined with the increase in technological innovations pose serious threats to the process of digital data transmission. The government, military, small and large businesses and corporations, and individuals transmit private or confidential information over public and private networks every day creating a need for preserving the confidentiality of this information. But because of the growth of the Internet and technology, the security of information and data being transmitted and received is at risk of being copied, destroyed, and/or modified. In this paper, an advanced, multi-level security steganographic method will be presented. The proposed system combines two hiding methods, namely Cryptography and Steganography. Cryptography involves encrypting the secret data or information into a non-recognizable cipher. Steganography is then employed using the Discrete Wavelet Transform (DWT) method, to embed the encrypted data into a cover medium to hide its existence. The proposed system employs wavelet-based fusion while manipulating the embedding strength factors in order to improve the overall hiding capacity, imperceptibility, robustness and security of the final steganographic image.
