Steganography is a powerful and effective data-hiding technique that has received great interest in recent years due to its effectiveness in maintaining the security of data transferred over the internet. To provide safe data transfer, various steganography technologies have lately been presented and developed. Steganography and encryption are basic methods of securing data exchange. A new algorithm is encrypted based on text messages and exchanges the bit positions around a key point using the Bi-LSB (Bi-Least Significant Bit) method. After adding the hidden message, the changed audio file appears to be the original carrier file. In comparison to previous experiments, the suggested approach increases hiding capacity by 30% while maintaining an acceptable stego. The Signal to noise (SNR) is 69.2 DB.

“…Confidentiality, integrity, and availability are three components of information security. This could be accomplished using information concealment techniques such as cryptography and steganography (Lenti, 2000) 4,5). The act of encrypting and decrypting digital data is referred to as cryptography.…”

Steganography is the practice of hiding data, such as images, videos, or text, within a cover image without it being detectable by the human eye. Several factors, such as the capacity, security, and robustness of the technique, are essential when transferring information using this method. In this study, we propose a new approach to image steganography that improves the Least Significant Bit (LSB) technique by utilizing images of 24 bits in each pixel. Improving the capacity and security of LSB-based steganography requires a combination of techniques, such as indirect embedding, embedding in multiple channels, and applying cryptographic and compression techniques. This approach conducts by encrypting each compressed secret message bit with the most significant bit of the red channel and then saving the output bit (hidden bit) in the least significant bit of the (green/blue) channel according to the row value (odd/ even). To further security, the suggested approach uses multi-level encryption; employs RSA to encrypt the secret message before applying the Huffman compression and encrypting the hidden bit by (XOR/XNOR) in the embedding method based on the row value of the pixel. Meanwhile, it is planned to use the Huffman coding technique to shorten the length of the encrypted message that will be inserted in the cover image. For the color photos in this work, the standard images were acquired from a standard dataset (USC-SIPI). The suggested approach performs better when measured in terms of mean square error (MSE), peak signal-to-noise ratio (PSNR), and comparison to findings from related prior efforts.

“…Initially, privileged information may be hidden in cover media via embedding. Second, extractions may be used for recovering secret bits from stego text [10]. In steganography information hiding, there are three characteristics in which the systems compete with each other: security, robustness, and capacity.…”

The need to hide essential information has rapidly increased as mobile devices and the internet has overgrown. Steganography is a method created to create hidden communication. Recently, methods have been developed to hide important information using text steganography. This work-study takes advantage of the possibility of concealing data in all diacritics after the two letters ال)) in the cover text. In the presented study, we propose a new algorithm in steganography in Arabic text as a cover text. After pre-processing the cover text, the algorithm hides the elements of secret messages inside the Arabic letters by adding appropriate diacritics (like Hamzah Al-Wasl) on the extracted words beginning with (ال) according to its third letter type (solar or lunar). In the proposed algorithm, the length of the secret message is determined so that the intended recipient can extract the hidden message accurately. The proposed algorithm is robust against the attack because the change in the cover text is small and imperceptible. On the other hand, since Arabic is used as a cover text, the breadth of the inclusion depends on the number of words beginning with (ال) definition.
