are aware that they are communicating. The idea of message concealment is to hide the message within text, graphics, and movies. Utilizing sophisticated computer algorithms and techniques that make it nearly impossible to isolate or detect a secret message is the fundamental objective of contemporary steganography. Digital (modern) steganography employs well-known strategies, including concealing messages in an existing cipher's least significant bits, hiding a message within an image's least significant bits, or mapping statistical features from one file to another to make the first file resemble the second. Steganography's fundamental benefit over cryptography is that, unlike ciphertexts, hidden communications do not draw attention to themselves. Steganography's fundamental objective is to make it difficult to detect the presence of a message, a file, or another piece of data within another message, file, or piece of data. The objective is normally to conceal the data so that they can be sent or stored in plain sight without being seen by anybody other than the intended recipient and still be accessible and understood by that recipient. Therefore, the main goal of steganography is to conceal a message to maintain its secrecy, whereas cryptography's objective is to maintain a message's secrecy by altering it, using the encryption key. Modern steganography's ultimate objective is to conceal data in a way that makes them impossible to detect in other data [14; 15; 16; 17; 18]. The original contribution of this technique lies in its application of Hermitian positive definite matrices for data-hiding purposes. Hermitian positive definite (HPD) matrices are not commonly utilized in traditional data-hiding methods, and their introduction represents a novel approach to secure information embedding. Hermitian positive definite matrices have specific mathematical properties that make them suitable for data hiding. These properties are leveraged to achieve a balance between imperceptibility and robustness, resulting in an original algorithm that enhances security while preserving the quality of the cover media. The use of HPD matrices in data hiding might lead to more sophisticated and secure steganographic methods, making it harder for unauthorized parties to detect and extract hidden data. The introduction of new approaches using HPD matrices might contribute to the development of more robust encryption and data protection methods, ensuring confidential information remains hidden from adversaries. The integration of HPD matrices into data-hiding algorithms may involve advanced signal processing and cryptographic techniques, leading to cross-disciplinary advancements in these fields. The contribution of the technique is in its ability to provide enhanced security and robustness in the data-hiding process. By utilizing Hermitian positive definite matrices, the method can resist various attacks and attempts to reveal hidden data, thereby ensuring a higher level of data confidentiality and integrity.
