In this project, first we have to encrypt the secret message that sender wants to send for the receiver. After encrypting, embed that cipher data into image file, the output is as a stego image and that stego image we have to store in unused field of ip header. Like, identification field is used only when fragmentation occurs, if we avoid fragmentation then identification field is always be unused, we can store our stego imgae in it. I have completed Encryption and Embedding part, but problem with the IP header. Please suggest how to read IP header using JAVA. Thanks in advance… Regards, Prashant Patil. If you want to manipulate packet headers in linux network stack you can use a framework called netfilter and work around with skbuff by writing a LKM, you can then provide an interface so that ur java application can read it out or pass required parameters in the user land application. _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies -- Regards, Santosh Kulkarni _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
