The accommodation of the digital images and its security

The accommodation of the digital images and its security play an important role in the present correspondences including military applications just as social networks. Notwithstanding, each image correspondence application should ensure that the moving images are intelligible just by the authorized party. To keep away from unauthorized attacks, most applications apply cryptography or steganography. Steganography is the art and science of encoding a secret message into a current correspondence channel or a payload in such a way the sender and expected receive know about its reality. While cryptography permits plain visibility of scrambled information, regardless of how weak it is, steganography conceals the presence of the information. The significant distinction between the two is that cryptography secures the substance of a message by encryption, while steganography ensures by concealing the message into irrelevant information. The strategy proposed in my research will attempt to join the cryptography with the steganography to give greater security while diminishing the opportunity of identification by an unauthorized party. In the accompanying segment, related past works in the field of picture covering up and their upsides and downsides will be clarified. Following that, the Reversed Chinese Remainder Theorem (RCRT), a scientific number hypothesis, will be quickly showed. Also, the proposed method, which depends on RCRT as well as the security and authentication issue, will be examined. At last, the test results will be introduced, which shows the prevalence of the proposed strategy in correlation with a portion of different methods.
