Abstract—Image steganography is a popularly used method of conducting secure on-line communication. We developed and tested four different models, which are based on the secret key enhanced LSB (Least Significant Bit) based approach, of hiding image and/or text for performance in the aspects of data type and size, processing time, and the quality of the stego-image. Those four models include image only, text only, and two proposed hybrid models for hiding image and text together. Our experimental results show a comprehensive performance metric of considering various aspects in the image steganography. It is also demonstrated that our proposed model (optimized version) of hiding image and text together outperforms the straight-forward implementation of the hybrid model in terms of processing time and capacity.
