A Smart Strategy for Data Hiding using Cryptography and Steganography

Confidential data maintained by Security sources has always been a substantial aspect of hampering unintended access. Technology is enhancing day towards information, especially in terms multimedia file transmission. Combining cryptography and steganography, crossover approach serves information security. Cryptography strategy for changing over from plain content Cipher Text. Steganography the specialty concealing text, which refers to hiding within message or file. The proposed method provides hybrid system designing utilizing steganography techniques, making communication reliable resisting attacks. In this paper, play fair cipher used encode hidden textual content, security effective level. Play represents text as unit converts these units into unknown forms. Later, Discrete Cosine Transform (DCT) Logical Operation Exclusive OR (XOR) techniques were combined with masking encrypted messages inside picture. Noble level results histogram analysis are achievements' values that indicate offers designed system.
