Steganography for Secure Data Transmission and Reception and Stegoanalysis

Jyoti Ashok Thange, Kailas Aade

Abstract: This paper introduces the steganography, it means hiding secure information and stegoanalysis. In Steganography message data is hiding behind cover data. Now a days number of techniques are available for hiding information such as Least Significant Bit (LSB), Discrete cosine transform (DCT), Discrete Fourier transform (DFT) and Discrete wavelet transform (DWT). The data content may be in text, audio, video or image. Basically this paper focuses on image steganography. Due to steganography it is possible to communicate between two authorized parties. This is the part of Steganography. But sometimes, it is necessary to find secure data from un-authorized parties to save our nation from terrorist hence next part of project is stegoanalysis. In stegoanalysis two types of analysis are done that is subjective analysis and objective analysis.
