Data concealment is an important task that must be undertaken to preserve the quality and protection of information being conveyed and to avoid data tampering. Cryptography and steganography cannot be alone used to protect data, rather they can be combined and used in a single system. This paper aims to keep the information secured from third-party users who might mistreat them. This paper provides a solution to create efficient information masking to safeguard and protect data delivered. AES encryption and LSB are two of the significant methods of data encrypting and hiding used in the presented work. The suggested the technique offers a method that combines the two different data hiding approaches into a unified system to provide improved data security. By encrypting data first and then hiding the encrypted data within an image or audio file, this integration of the two approaches improves data security. The results obtained from this work produced a high-quality standard stego image/ audio. To analyse the results of project PSNR and MSE value of the stego image/ audio are evaluated, the obtained metrics from the evaluation suggest that the system produces a high-quality stego image and stego audio.
