Perfectly Secure Steganography: Capacity, Error Exponents, and Code Constructions

  title={Perfectly Secure Steganography: Capacity, Error Exponents, and Code Constructions},
  author={Ying Wang and Pierre Moulin},
  journal={IEEE Transactions on Information Theory},
An analysis of steganographic systems subject to the following perfect undetectability condition is presented in this paper. Following embedding of the message into the covertext, the resulting stegotext is required to have exactly the same probability distribution as the covertext. Then no statistical test can reliably detect the presence of the hidden message. We refer to such steganographic schemes as perfectly secure. A few such schemes have been proposed in recent literature, but they have… CONTINUE READING
