RSA ALGORITHM AND HASH LSB TECHNIQUE FOR IMAGE STEGANOGRAPHY

DESIGN DETAILS Steganography is a method of hiding secret messages in a cover object while communication takes place between sender and receiver. Security of confidential information has always been a major issue from the past times to the present time. It has always been the interested topic for researchers to develop secure techniques to send data without revealing it to anyone other than the receiver. This Matlab design is based on image steganography i.e., Hash-LSB with RSA algorithm for providing more security to data as well as data hiding method. First input image of size 512 x 512 is selected as a cover image and a secret message which will be embedded in the cover image. The Hash based Least Significant Bit (H-LSB) technique for steganography in which position of LSB for hiding the secret data is determined using hash function. Then image steganography using RSA encryption technique to encrypt the secret data. The detailed design procedure is given below, EMBEDDING ALGORITHM Step 1: Choose the cover image & secret message. Step 2: Encrypt the message using RSA algorithm. Step 3: Find 4 least significant bits of each RGB pixels from cover image. Step 4: Apply a hash function on LSB of cover image to get the position. Step 5: Embed eight bits of the encrypted message into 4 bits of LSB of RGB pixels of cover image in the order of 3, 3 and 2 respectively using the position obtained from hash function given in equation 1. Step 6: Send stego image to receiver. DE-EMBEDDING ALGORITHM Step 1: Receive a stego image. Step 2: Find 4 LSB bits of each RGB pixels from stego image. Step 3: Apply hash function to get the position of LSB’s with hidden data. Step 4: Retrieve the bits using these positions in order of 3, 3, and 2, respectively. Step 5: Apply RSA algorithm to decrypt the retrieved data. Step 6: Finally read the secret message.
