WebJul 7, 2015 · For example, the simplest algorithm would be to follow the jpeg encoding process (split image in 8x8, DCT each block, quantise coefficients) and then apply your steganography algorithm on those integer coefficients as if they are pixels. Then carry on with the jpeg encoding by saving those coefficients in a jpeg format. – Reti43 Webthe destination without being detected. In this paper we present an image steganography that combines Discrete wavelet transform(DWT),Least significant bit(LSB) and Encryption techniques on raw images to enhance the security of secret message. Intially, DWT algorithm is used to transform image from spatial domain to frequency domain.
