In this paper, a flexible dot-pattern based mapping technique for steganographic encoding of messages is presented, with the aim that statistical analysis would not reveal the secret message even if the steganographic system is under attack and the hidden bits are revealed from the cover media used in the steganography technique like text, image etc. To retrieve the message the attacker needs to know the specific mapping scheme used to encode the characters with dot pattern. Thus the method presented is highly secured compared to traditional steganography schemes where standard characters to bits mapping techniques are used. The corresponding binary data is generated from a specific and personal Dot Pattern Character Encoding Scheme (DPCES), which is embedded onto the cover media and sent through the public channel to the intending receiver having prior knowledge of the communication-specific encoding scheme. We have implemented the proposed DPCES using Visual Studio 2015, and tested with image covers which show that the stego media can maintain desired secrecy.
