In revolutionary stage, network Security is one of most significant problem . To pause this problem as well as to protect data we use cryptography and steganography. Steganography hide our data within image and looks like original image so anyone can’t understand other data hide behind image. Secrete writing is cryptography. Cover writing is known as steganography. Two tier securities are provided to secret data by our proposed method. In cryptography we use RSA algorithm to encrypt secret message and Hash function with least-significant-bit (HLSB) technique is used to hide encrypted message into true color RGB image. Our proposed method gives cavalier quality stego images.
