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.

Abstract

This paper presents several techniques used in text steganography in term of feature-based and word-rule based. Additionally, it analyses the performance and the metric evaluation of the techniques used in text steganography. This paper aims to identify the main techniques of text steganography, which are feature-based, and word-rule based, to recognize the various techniques used with them. As a result, the primary technique used in the text steganography was feature-based technique due to its simplicity and secured. Meanwhile, the common parameter metrics utilized in text steganography were security, capacity, robustness, and embedding time. Future efforts are suggested to focus on the methods used in text steganography.

Abstract

This paper presents a review of the compression technique in digital image processing. As well as a brief description of the main technologies and traditional format that commonly used in image compression. It can be defined as image compression a set of techniques that are applied to the images to store or transfer them in an effective way. In addition, this paper presents formats that use to reduce redundant information in an image, unnecessary pixels and non-visual redundancy. The conclusion of this paper The results for this paper concludes that image compression is a critical issue in digital image processing because it allows us to store or transmit image data efficiently.
