Abstract: These days, data privacy and secure data communication is one of the main concerns which led to design various techniques to encrypt the data and transmit it in a secure way. Steganography is the mechanism in which the secret message is transferred by hiding it in a covered file such as any media i.e., image, video, audio, etc. Various researches have been made in order to transmit the data in a secure way. Recently, to this end, the 2-1-4 LSB technique was used with RSA and SVD for color image. This approach was proved to be better, but after performing a literature survey, some pitfalls of this technique are observed. Thus, in this paper, a novel technique is proposed to perform secure steganography. In the projected approach, two novel techniques- Huffman Encoding and enhanced fuzzy controlled edge detection are introduced to encrypt the input data and extract hiding location respectively. Simulation is performed using MATLAB tool. Peak-to Signal Ratio, Mean-Square Error and embedding time are three parameters that are used to determine the performance of the proposed system. Comparative analysis of projected and existing techniques is performed which ensured the efficacy of the novel approach.

Keywords: Steganography, Advanced fuzzy edge detection technique, Huffman Encoding, PSNR, MSE, embedding time.
