Cryptographic-steganography network communication

Abstract

Data security is vital for any firm as the automation of data transferring improves efficiency and productivity. The proposed software not only ensures data security but also serves as an important and effective tool in the efficient functioning of an organization. Besides protecting data while transferring it through the insecure channels, it also serves to maintain a highly useful database, which is of immense help when it comes to maintaining highly confidential documents, credit card details as well as employee records. The primary objective of this system is to protect confidential documents by implementing cryptographic techniques such as encryption and decryption. Cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent, as well as concealing the contents of the message. Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. The proposed system will accept a data file or message as input and hide the contents in to a media file like an image as per user's choice; after that it will encrypt with a secure cryptographic algorithm like Rijndael. The resultant cipher output is sending to the receiver through any network. The same way recipient can decrypt the data using reverse engineering technique.
