Analysis review on spatial and transform domain technique in digital steganography

Abstract

This paper presents several techniques used in digital steganography in term of spatial and transform domain. Additionally, it analyses the performance and the metric evaluation of the techniques used in digital steganography based on spatial and transform domain. This paper aims to identify the main mediums of digital steganography, which are image-based, video-based and audio-based, in order to recognize the various techniques used with them. As a result, the primary technique used in the digital medium was LSB technique in the spatial domain, while in the transform domain, the main technique used was differentiated between DTC and DWT. Meanwhile, the common domain utilized in digital steganography was the spatial domain due to its simplicity and high embedding capacity. The future efforts for this paper will be considering the feature based in text steganography.

“…Therefore, most steganographic techniques related to audios and images are implemented to video too. Steganography in the video is similar to steganography in the images apart from data is hidden in each frame of the video [1], [18], [47], [48], [54]- [57], [65]- [68], [20], [69]- [77], [22], [23], [33], [34], [43]- [45]. The main advantages of embedding information in a video are the huge amount of information that are hidden inside the covers [4], [11], [17], [22], [40], [45], [48], [51], [57], [78], [79].…”

“…The size of the information does not issue in video steganography because it is embedded inside multiple frames. Although video steganography bear the large size of the message [1], [18], [48], [54]- [57], [65]- [69], [20], [70]- [77], [22], [23], [33], [34], [44], [45], [47]. But it is necessary the algorithm selects the best bits to embed the information on it [11], [23], [47], [59], [69], [76], [80], [81].…”

“…In general, there are two types of steganography in the video, the first one in the spatial domain and the second in the frequency domain [11], [18], [40], [59], [82]. In the spatial domain, this technology directly changes the pixel value of the video cover to obtain the desired improvement.…”

“…In the spatial domain, this technology directly changes the pixel value of the video cover to obtain the desired improvement. This method is considered one of the most common methods of steganography and is called least significant bit (LSB) [18], [40], [59]. One of the advantages of this method is that it provides a high capacity of data embedding.…”

“…The digital medium includes all known multimedia types such as video, images, text, and others [27]. One of the most important goals of the process of steganography in digital media is to make the secret message that is sent over the internet difficult to access by unauthorized persons [4], [11], [17], [18], [23], [28]- [34]. Also, the hiding process also takes place in a manner that does not attract the doubt of any third party having a secret message  ISSN: 2502-4752 Indonesian J Elec Eng & Comp Sci, Vol.…”
