Secure document transmission framework using digital image steganography

摘要

Document transfer is one of the most vital emerging area in all the sectors throughout the world. It is nothing but converting the document in digital form and transmitting the packet securely from one node to another. Secure transmission of all the data packets is too much important, when dealing with confidential information. An attacker can catch the packets in the network, with the help of packet sniffer. The aim of proposed system is to improve security while transmitting a confidential file from one node to another. This system is using digital image steganography which will create a high security standard in network for secure document transmission. Digital Image Steganography system securely transfer text messages by hiding them in a digital image file. A mishmash of encryption algorithms and steganography provides a strong backbone for its security. The confidential document is given as input to the proposed system and then converting the document in binary form and embedding it into pixels of image will be takes place. This system is also going to provide different number of functionality for the user benefits.
