Abstract
The rapid advances of network technologies and digital devices make information exchange fast and easy. However, distributing digital data over public networks such as the Internet is not really secure due to copy violation, counterfeiting, forgery, and fraud. The paper presents a study and analysis on Multi-Level Steganography (MLS) which defines a new concept for hidden communication in telecommunication networks. In MLS, at least two steganographic methods are utilized simultaneously, in such a way that one method (called the upper-level) serves as a carrier for the second one (called the lower-level). In our work we have used two steganographic algorithms. This paper presents a steganographic algorithm based on the spatial domain, Selected Least Significant Bits (SLSB) and Least Significant Bits (LSB). This method is further exploited to do a 3-level re-steganography to enhance security. We have performed some simulations by using MATLAB software on different possible combination of the SLSB and LSB. Finally in our analysis we have concluded the LSB–LSB –LSB combination result best than rest of the combinations.
