Abstract-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. Keywords: Image Steganography, Interpolation, PSNR, MSE, Braille method.I. INTRODUCTION Information Technology plays a vital role in present era of advancement in technology. Due to rapid advancement in technology, need of secure data transmission (data security) provides great challenges to researchers and also encourages researchers to promote higher level security techniques. These security techniques protect the susceptible data transmission between sender and receiver from intruders to interrupt over network. In this regards, information hiding system provides different techniques to establish secure communication. [1] Information hiding system approaches two well known techniques named as Cryptography and Steganography. Cryptography technique only concentrates on data hiding by encrypting the confidential message from original to another form but do not able to obscure the existence of the confidential message during communication. But Steganography is an art that aims to intact the private communication by conceal the information in a well suited multimedia cover and reduces the chances of attack via intruders over network compared to cryptography technique. In information hiding system, image Steganography is well-known idea to hide the confidential information via cover image [2][3]. Two common types of Image Steganography are Spatial Domain and Transform Domain. In spatial domain message bits are directly embedded in cover image pixels for example LSB Technique. In transform domain firstly cover image pixels transformed after that message embedded within transformed pixels of image for example DCT, DWT etc [4].II. LITERATURE REVIEW N.F. Jonson et al., introduced LSB insertion method. It is much easier approach for insertion of message within cover image to hide the confidential information. In this method, LSB of each pixel flipped with the each message bits in sequence and after the insertion LSB of each ...
