This research presents a technique for protect the data through using cryptography and steganography. The cryptography stage is using Play fair cipher to encrypted the secret message. In steganography stage convert Playfair cipher text to binary and store the first bit in every letter in secret message in the LSB of pixel in the image and then the second bit in every letter embedded in the LSB of pixel and continue so until the last bit in last letter in the secret message. The greater size of the text more difficult to decode See's picture does not know what the image bits and what are bits of text.
