Robust Data Security through Hybrid AES-RSA and LSB Steganography Techniques

In today's interconnected digital landscape, exchanging information and data has become integral to our daily lives. Steganography offers a unique approach to secure data communication by concealing sensitive information within seemingly innocuous digital content. However, traditional steganography methods also have their disadvantages. They can be susceptible to detection by advanced steganalysis techniques, and their compatibility with specific file formats can be limiting. This paper proposes Hybrid AES-RSA encrypted LSB, a two-layered approach to address the shortcomings of conventional steganography. This approach ensures that the information is well-hidden within digital content, while encryption provides an additional layer of protection to prevent unauthorized access. Our proposed method, Hybrid AES-RSA Encrypted LSB, achieves an SSIM (Structural Similarity Index Measure) index of 0.99 for images, The achieved accuracy of 97% is 13.25% higher than the traditional LSB method, underlining the effectiveness of our proposed hybrid technique.
