Modern cybersecurity systems are very often based on cryptographic and steganographic protocols, which ensure the security and integrity of information. In this paper, we present a novel steganographic protocol that enhances the security of covert communications by integrating secret sharing schemes with distributed steganography. By employing a \((k, n)\) threshold scheme, a confidential message is partitioned into  \(n\)  distinct shares, each embedded into separate media containers using steganographic methods guided by stego keys derived from a key container. This approach distributes the risk, ensuring that the interception of a single container does not compromise the entire message. The protocol details both the encoding and decoding processes, emphasizing how the use of multiple containers and secret sharing increase resilience against detection and unauthorized access. Our technique offers a higher level of security for transmitted data and robust protection against common cyberattacks, advancing the capabilities of modern cybersecurity systems.
