HYSA: HYbrid steganographic approach using multiple steganography methods

Abstract

The aim of image steganography is to hide data in an image with visual and statistical invisibility. There have been a number of steganography techniques proposed over the past few years. In sequence, the development of these methods has led to an increased interest in steganalysis techniques. Most of the steganalysis methods attempt to estimate cover image statistics. One way to provide a secure steganography method is to disturb the estimation of steganalyzers. The main concern of this paper is to resist against steganalysis methods and utilize a mechanism to securely embed more secret data into an image. We present HYbrid steganographic approach (HYSA), which embeds secret data with randomized embedding algorithms in randomized regions of the cover image. HYSA embeds secret data in only some regions of the image not all over the image. In addition, HYSA can employ more than one steganography method for embedding secret data in the image. Random selection of embedding regions and steganography methods leaves a combination of several types of distortion on the image, which are difficult to be recognized by the steganalysis methods. Experimental results by applying some well-known and efficient steganalysis methods illustrate that the proposed steganographic approach is more undetectable than some popular steganography methods.

“…If t = π/2, then x(t) = À0.5 * 0 À 1.5 * 1 + 1.5 = 0; y(t) = 0.5 × 0 À 1.5 × 1 + 1.5 = 0; Hence, the coordinate is (0, 0) in first quadrant, and the other coordinates are (2, 1), (3,3) and (1,2).…”

“…Information security should be true, discrete and should be based on the available data. Steganography is one of the secure data communications for highsecurity message transmission [1][2][3][4][5]. This is a method that embeds secret information into a cover file.…”

“…Furthermore, the hybrid steganographic methods are more secure, because many steganalysis detection attacks are specifically designed to target a singular steganography method [10][11][12]32]. Thus hybrid embedding approaches generally confuse the statistical steganalysis methods used to detect the stego-images [33].…”

Steganalysis based on steganography pattern discovery

“…Adaptive steganography schemes like WOW [13], started with the advancement of coding schemes [14] capable of embedding messages while nearly optimally minimizing arbitrarily defined additive distortion functions. Since the capacity of steganography methods is limited based on the properties of images, and the goal of the steganography methods is to be undetectable, the researches in [15][16][17][18] are about increasing the embedding capacity of steganography methods to provide the capability of embedding larger secret messages.…”
