Abstract: Various techniques for information hiding in audio files are available and are widely used for secure communication and digital identification. Commonly used methods of steganography add data into a cover file in the form of noise. However, retaining the information hidden in a particular signal after compression or other processing performed on the latter is inevitable. Echo hiding introduces change in the cover audio, rather than adding noise to it, which makes the hidden information immune to any kind of processing performed on the signal. We provide an enhancement to the conventional technique for echo hiding and the method of finding suitable parts in the file fit for hiding data without loss.

Abstract: In this paper we propose an implementation technique for sequential circuit using threshold logic. With the advancement of nano technology threshold gate based logic design has got a new direction. In this paper first negative edge triggered D flip-flop has been designed. Then negative edge triggered T flip-flop has been designed .Finally threshold gate based counter has been realized. The proposed design has been verified by means of simulation using VHDL.
