Combining Cryptography and Steganography for Efficient Secure Image Transmission

Abstract

The security of data transferring is accepted as the challenging problem all over the world. In this system, the image file of any kinds of format is encrypted by using S-DES (Simplified Data Encryption Standard) in Cryptography, and then the cipher is embedded into the innocuous cover image file by using LSB (Least Significant Bit) in Steganography. Since SDES is a standard education algorithm providing a tradeoff between encryption speed and security that is required for image encryption, encryption and decryption process of this system is extremely fast. To be more secure, cover image file is used to hide the obtained cipher. As this system takes the advantage of both techniques, image transferring is more confidential. In this paper, the system implements SDES and LSB.
