Abstract

Nowadays digital communication plays a very essential role in our daily life, because lots of applications and online activities are based on internet. Transferring the secure data over the network has become a major issue. Protecting the confidentiality and information integrity against unauthorized user to access and use is very important. Today many systems are available with various effort to maintain the secure data and to overcome these issues. Cryptography and steganography are the two important methods available for the secure message. This paper proposed a dynamic password generation approach for authentication measure. Once the user register to the system the identification code will be sent to the registered Email ID of the user. Later, user will input it as PIN to access the confidential data. This paper also contains the strength of combined cryptography and steganography techniques to enhance the security of communication over an open channel.
