SilentSecrecy: Hiding in Image and Audio Using Spread Spectrum Technique with an Image Stenalysis Plug-In
AbstractThis paper presents a proposed scheme which employs a steganography technique to hide and retrieve data or file along with steganalysis technique to analyse suspicious image file. Due to the growth of technology, people tend to keep information electronically. Private information can be obtained by unauthorised use without knowing. With the usage of both steganography and encryption method, the unauthorised user might have difficulty on getting user private information. On the other hand, steganalysis is an ill-posed problem. The original host data is unknown, the rate of hiding (if data is hidden) is not known and the number of steganography scheme is large. In this research, it will clarify what steganography is, the definition, the technique used in implementing steganography as well as steganalysis. This study focuses on the Spread Spectrum technique in hiding data or file in a media file (MP3 and JPEG) and statistical steganalysis technique that is Chi-Square attack. The proposed scheme is then analysed and evaluated the payload size, stego image resolution and the occurrence of hidden data in an image file. The significance of the proposed scheme is the user can embed and retrieve secret data from media file, while Chi-Square attack able to analyse the hidden message in an image.
Submission of an original manuscript to the Journal of Computing Technologies and Creative Content (JTeC) will be taken to mean that it represents original work not previoussly published, that it is not being considered elsewhere for publication. All submitted articles that are published by JTeC cannot be published anywhere by the authors unless with the permission by JTeC Editors. JTeC reserves the right to the publications of the articles it published, and reserves the right to reuse the articles elsewhere for academic purposes, while still retaining the names of the original authors with the original articles.
JTeC takes the stance that the publication of scholarly research is meant to disseminate knowledge and in a not-for-profit regime, benefits neither publisher nor author financially. It sees itself as having obligation to its author and to society to make content available online now that the technology allows for such possibility.
