Project Summary

Steganography aims to transmit information invisibly, embedded as imperceptible alterations of cover data; steganalysis aims to unmask the presence of such hidden data. By combining steganography with cryptographic mechanisms, it is possible to add valuable properties, which are originally left to cryptographic systems. However, new problems for cryptographic mechanisms arise from the context of steganography. So far, these are not inspected thoroughly.

We will tackle the challenge of coupling cryptography with steganography from both directions. On the one hand, we will carry out practical and theoretical attacks and on the other hand, we will design improved systems.

Our goal is a best-practice catalogue of how to integrate cryptography into steganographic systems as well as of specific problems of encoding in the context of steganography. We will back our advices with scientific insights derived from experiments.
