Secure And Undetectable Multi-Cloud Steganography: Leveraging Non-Alteration Techniques For Covert Communication

Abstract

Classical steganography faces challenges such as covert channel detection and message loss, while distributed steganography complicates detection through cloud storage by fragmenting messages across varied media. A novel multi-cloud steganography paradigm addresses these issues by distributing secrets without altering files, bolstering security and undetectability. This approach seamlessly integrates information using a covert channel model, strategically arranging clouds, authenticating accounts, and utilizing disjointed file lists. A critical examination of the method's security strength challenges claims of computational infeasibility, suggesting enhancements for increased security against brute force attacks. The accompanying paper underscores the dynamic nature of steganography in multi-cloud environments, emphasizing the continuous need for robust security measures in this intricate field.
