In 2008 Zhang, Zhang, and Wang proposed a steganographic construction that is close to upper bound of efficiency. However this system and many other are fragile to errors in the stegocontainer. Such errors can occur for example during the image processing. In this paper the ZZW-construction is modified for extracting data if errors and erasures occur in stegocontainer. It is shown that the correction is possible when linear codes in projective metrics (such as Vandermonde metric and phase rotating metric) are used. The efficiency of proposed construction is better than one for the well-known efficient combinatorial stegosystem.
Keywords: combinatorial steganography, projective metrics, Vandermonde metric, linear code, ZZW-construction.
