Steganalysis is the art of detecting the message's existence and blockading the covert communication. Various steganography techniques have been proposed in literature. The Least Significant Bit (LSB) steganography is one such technique in which least significant bit of the image is replaced with data bit. As this method is vulnerable to steganalysis so as to make it more secure the authors encrypt the raw data before embedding it in the image. Though the encryption process increases the time complexity, but at the same time provides higher security also.
