Data Hiding for Covert Wireless Communication
Overview
Our project aims to explore, implement and compare two different wireless communication methods for data hiding. The first method involves LSB steganography, where the secret message is embedded in the least significant bits of an image. This image will be transmitted using DSSS or FHSS, adding an additional layer of obfuscation, making the transmission harder to detect and follow. The second method is Spread Spectrum Image Steganography (SSIS a method found in a research paper), which hides the message as noise transmitted along with the image. SSIS offers a higher payload and stronger concealment, as LSB-based methods can be easily decoded by inspecting the image’s least significant bits. In contrast, extracting the hidden message in SSIS requires a matching key to reproduce the pseudorandom noise used during transmission, providing enhanced security.
Community Benefit
This project compares two wireless data-hiding methods to give users more informed options based on their specific needs. By understanding the strengths and weaknesses of these methods, individuals can more effectively hide sensitive or important information, particularly in environments where wireless communication is censored or monitored.
