N2 - Embedding hidden data is usually performed by introducing some distortions (errors) in cover objects. If the distortions exceed a certain bound, steganalysis can detect the presence of hidden data. So the problem is to embed as much data as possible and not exceed a permissible distortion level to ensure indetectability. We describe a general class of stegosystems that solves the problem by employing linear hash functions. The suggested stegosystems allow to transmit hidden information of the amount asymptotically close to the maximum possible under the given distortion.
