Ensuring data security has become a serious concern as it has evolved into a multifaceted problem. Over the past few decades, many security measures have been developed to address this issue. However, cryptography and steganography are the most commonly used tools to ensure the security of sensitive data. Cryptography involves encoding secret messages, while steganography involves hiding messages within digital media and images. While both methods have their advantages, cryptography is more suited for secure communication, while steganography is better for hiding sensitive information. In our paper, we propose a two-tier encryption approach to ensure data security. We use the AES algorithm to generate a top-secret message in the first layer, and the LSB image steganography method to encrypt the information in the second layer. By combining these two encryption methods, we ensure the confidentiality, integrity, and availability of the data. We perform comprehensive testing and analysis on our proposed methodology to validate its efficiency, effectiveness, and reliability.
