Abstract This research introduces a comprehensive security model that combines steganography and cryptography to enhance data protection and secure information sharing. The security model utilizes the AES cryptographic algorithm and LSB steganographic techniques to reduce risks associated with data tampering, loss, and theft in organizations. The model incorporates three fundamental security principles: confidentiality, integrity, and availability (CIA Triad), forming the foundation of robust data protection. The study presents a systematic approach to the development of a steganography application using Python programming language and relevant packages such as Pillow, NumPy, Open-cv Python, and Stegano. The user-friendly application enables users to upload images, input hidden messages, and perform actions such as saving the stego-image and retrieving concealed data. The encryption process involves embedding messages within images and compressing the stego-image using the 7zip file compressor with AES-256 encryption. The compressed stego-image is then securely transmitted via email along with a password hint for the recipient. The implementation idea of Identity-Based Encryption was introduced to send the AES key to recipients. Recipients can successfully decrypt the image using the provided password, unveiling the concealed message. This research has demonstrated that combining steganography and cryptography offers an efficient and effective solution for secure information sharing. Screenshots and visuals illustrate each step of the application's operation, emphasizing its user-friendliness and ease of use. Overall, the proposed security model provides a robust framework for safeguarding sensitive data and information in various organizations.
