Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of NAUN Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

Abstract: Security of confidential information in the insecure era of information transmission (Internet) is still one of the most important challenges of the day. The combination of cryptography and steganography increases the security of embedded data to avoid from unauthorized access. Furthermore, compression of secret data reduces the size of transmitted message. In addition to compression and encryption, in this paper, two stage steganography is employed to enhance the security. In the proposed approach, the Huffman coding as lossless compression, the Blowfish, DES, 3DES, AES, and RSA as cryptography algorithms and LSB (Least significant Bit) as steganography technique are employed with enhancement of security by two stage steganography. The results are analyzed through quality parameters including MSE (Mean Square Error) and PSNR (Peak Signal to Noise Ratio), and histogram of images.
