A Cryptographic Approach for Steganography
This work addresses the need for more practical and secure steganographic methods, representing a foundational shift rather than an incremental improvement.
The paper tackled the problem of formalizing security in steganography by replacing information-theoretic paradigms with cryptographic ones, resulting in the first proof of a cryptographically secure information hiding scheme.
In this research work, security concepts are formalized in steganography, and the common paradigms based on information theory are replaced by another ones inspired from cryptography, more practicable are closer than what is usually done in other cryptographic domains. These preliminaries lead to a first proof of a cryptographically secure information hiding scheme.
