How to provide network security on steganography

  1. Feb 9, 2007 #1
    I got a difficulty in my final year project.It is made on
    steganography.But I don't understand how to provide network security
    during data transfer..though we know it theoretically bt dealing it
    practically is a bit problamatic..In it we are using image file as
    carrier file ..i need some suggestions and ideas on how to provide
    this security.

    what protocol are you going to use for data transfer?

    You need secure communications over internet?

    IF so try SSL

    http://en.wikipedia.org/wiki/Secure_Sockets_Layer

    If you are using Java Technology you have SSL features in the standard library.

    I would naively say just use SSLServerSocket instead of ServerSocket

    http://java.sun.com/javase/6/docs/api/javax/net/ssl/SSLServerSocket.html

    But this is part of cryptography, isn't the deal with steganography that you send like a plain picture no cryptography involved but no one except you and the reciever know that there is a message hidden in the picture? Like it would look a clear Rembrandt but if only look at the least digit of each pixel you have another hidden image, soo you can put this image on your public web site, no need for secure communications?
