An Information Security System Based on Optimized Pixel Mapping Method Su Mon Thu Khin Myo Thant <p>In&nbsp; the&nbsp; field&nbsp; of&nbsp; communication&nbsp; system&nbsp; and&nbsp; internet,&nbsp; the&nbsp; information&nbsp; security&nbsp; is&nbsp; playing&nbsp; a&nbsp; crucial&nbsp; role.&nbsp; At&nbsp; the<br> present time, communication through Internet is becoming popular and it&nbsp; should be accurate and secure. To<br> make&nbsp; it reality, cryptography is very&nbsp; useful tool to protect the content of confidential&nbsp; data in&nbsp; many research<br> areas. Another one, steganography is also commonly used to hide the existence of data into cover media known<br> as&nbsp; text,&nbsp; image,&nbsp; audio&nbsp; and&nbsp; video.&nbsp; In&nbsp; this&nbsp; work,&nbsp; it&nbsp; is&nbsp; considered&nbsp; that&nbsp; the&nbsp; two&nbsp; most&nbsp; popular&nbsp; techniques<br> (Cryptography and Steganography) should be combined to develop the strong and robust security system. At<br> first,&nbsp; confidentiality&nbsp; and&nbsp; message&nbsp; authentication&nbsp; requirements&nbsp; are&nbsp; fulfilled&nbsp; with&nbsp; the&nbsp; help&nbsp; of&nbsp; Byte-Rotation<br> Encryption&nbsp; Algorithm&nbsp; (BREA)&nbsp; and&nbsp; Secure&nbsp; Hash&nbsp; Algorithm-512(SHA-512).&nbsp; On&nbsp; the&nbsp; other&nbsp; hand,&nbsp; a&nbsp; new&nbsp; data<br> hiding approach based on the optimization of Pixel Mapping Method (OPMM) also provides the&nbsp; system the<br> higher embedding capacity with minimum degradation of stego image quality. To analyze the performance of<br> the proposed OPMM, the comparison is also presented in terms of embedding capacity and Peak Signal to Noise<br> Ratio (PSNR) values.</p> 2016-09-23 http://hdl.handle.net/20.500.12678/0000003111 https://meral.edu.mm/records/3111
