Abstract:
The information hiding is progression of hiding the details of a function or object or both of them. On the other
hand it represents an important way that used in data security. Another name for information hiding is the
steganography, which hides the data inside another data such as embed text inside image or image inside another
one. The steganography techniques were used from ancient times and through uses of many mechanics and
different ways, such as writing in invisible ink in the Greek Testament, while Cryptography is the process of
hiding information by encrypt this data using a complex algorithms. Cryptography is used when collaborating
over an untrusted intermediate such as internet. The steganography and cryptography work similarly but in
different contexts. In this study, an integration of cryptography and steganography to produce an efficient and
robust model has been presented. In terms of cryptography, the Data Encryption Standard (DES) algorithm is
implemented, whereas in steganography, the Least Significant Bit (LSB) algorithm is used. Our results show
efficient time implementation and a robust algorithm mechanism in terms of peak signal-to-noise ratio (PSNR),
signal-to-noise ratio (SNR) and mean square error (MSE).
