Steganography means concealed writing of secrete information within any cover media.In image Steganography for the purpose of privacy of secrete message, it is embedded within an innocuous image without knowing the existence of information to the intruders.To maintain the privacy and in direction to maximize it, this proposed technique used the Braille method.Braille method is the interpreting technique to scan the words for the blind peoples.So, with regard to make the secrete information invisible to the intruder Braille method helps a lot.In the proposed technique message characters are converted into 6 bits Braille's binary representation and then embed the message bits within the interpolated pixels of cover image.Interpolated cover image is hatched through the actual image by using interpolation method and all message bits are inserted within the interpolated pixels from left to right using the even odd pixel value approach with parity checker.The proposed technique maximizes the message hiding capacity and also improves the PSNR and MSE value as compared to existing techniques.
