therefore the decimal digit‚ much later renamed the hartley in his honour as a unit or scale or measure of information. Alan Turing in 1940 used similar ideas as part of the statistical analysis of the breaking of the German second world war Enigma ciphers. The main landmark event that opened the way to the development of communication theory was the publication of an article by Claude Shannon in the Bell System Technical Journal in July and October 1948 under the title ’A Mathematical Theory of Communication

ABSTRACT Transferring vital information securely without any threat of intrusion is extremely important. Crypography and steganography‚ both provide security to messages. But‚ it would be best if both of these are combined and provide a high-level of security. Cryptography only scrambles a message into a form which can’t be understood whereas steganography hides the information in a vessel like Image‚ Audio or Video. In this Paper‚ a combination of four techniques is done to analyze the level of

Inside the castle‚ King David grew more and more impatient‚ listening to the man who assaulted him. “I still do not understand why we’re here‚” he interjects. “If it was just to confirm their deaths‚ you could’ve saved us the long journey and written me. I would have made the announcement to my people on your family’s behalf. Instead‚ appears you gather us all here to put on a show.” “Yeahhhh‚” part of the room shouted in agreeance with their King. “What I have to reveal‚ must be heard. The written

to break German codes encrypted using Enigma machines. It shows the process through which Turing worked to crack the code. When Britain declares war on Germany in 1939‚ Turing joins a cryptography team‚ led by Commander Denniston‚ aiming to crack ciphers created by Enigma machines‚ which the Nazis use to provide security for their radio messages. Turing prefers to work alone‚ considering his teammates unnecessary. He designs a machine to decipher Enigma‚ but funding for it was refused by Denniston
