【Abstract】Secure transmission of data is achieved through the steganography images, where the secret data are embedded and transmitted so that the prohibited users couldn't able to access the data. In this research, the data are embedded in the optimal location of the network using the proposed FIEO Optimal Location Enabled Stegochain. The algorithm effectively determines the location for the embedding of secret data in the finest region of the image with faster convergence. The two different steps utilized in the research is the determination of the optimal location for embedding the image using the proposed algorithm and the embedded image transformation using the discrete wavelet transform while transferring the image is the first step. And the reconstruction of the original image at the receiver side with the help of the Inverse discrete wavelet transform is performed (IDWT). The performance of the proposed method is evaluated in terms of the performance metrics such as correlation co-efficient, and PSNR with the salt and pepper noise is 0.777, and 52.588 respectively. Similarly, for the random noise the correlation coefficient and PSNR obtained by the proposed method are 0.796, and 52.397 respectively.
