-The paper states the approach of embedding text secret message into an JPEG image file by dividing the entire image into blocks of 4 pixels and finding the key position using the values of RGB from the first block and then arranging the entire blocks into array and selecting particular blocks randomly for embedding the secret message. The idea is to finding a random pattern that is not easy to recognize by an attacker and along with that spreading the secret message throughout the image to cause a smooth distribution that will not affect the image quality much with a high capacity for data embedding.
