This study describes a novel audio steganography approach based on paying a cryptographic hashing of audio samples in order to improve perceptual invisibility and security in the embedding procedure through a secret key. The suggested method uses a secret key to hash the most significant bit (MSB) of the audio samples for picking only certain samples for modulo embedding. The selection technique applied in this scheme by hashing the samples makes the watermark imperceptible to the unauthorized and reduces the probability of statistical detection by a huge amount. The two bits of the picture data are placed carefully into the LSB of the selected audio samples. Because of the careful placement of the watermark in the least significant byte (LSB) of the audio samples, the extracted watermark was found intact. A noticeable improvement in the quality of audio after the extraction process was observed.
