Steganography

Steganography is a C++ steganography tool which leverages the LSB and DCT embedding techniques.

Dependencies

• OpenCV
• Boost C++ Libraries

Building

The steganography executable is build using the CMake build system and requires all of the libraries listed above in the dependencies section.

# Configure the build
cmake -B build

# Build steganography with the release optimisations
cmake --build build --config Release --target steganography

# Run the executable
./bin/steganography

Testing

Unit testing is provided to determine if the application is working correctly, the testing uses Catch2 and can be run by building and running the steganography-testing executable.

# Configure the build
cmake -B build

# Build steganography-testing with the release optimisations
cmake --build build --config Release --target steganography-testing

# Run the unit testing
./bin/steganography-testing

Usage

A command line user interface is provided to allow the encoding/decoding of data using either the least significant bit (LSB) or discrete cosine transform (DCT) technique.

# Encode using the DCT technique
steganography encode --technique dct payload carrier

# Decode using the DCT technique
steganography decode --technique dct carrier

# Encode using the LSB technique
steganography encode --technique lsb payload carrier

# Decode using the LSB technique
steganography decode --technique lsb carrier
