TE-SEM5_PL-02
(Programming Laboratory II)
------------------------------
Practicals List:
-----------------------------
Assignments Group A (Mandatory)
1 Implementation of following spoofing assignments using C++ multicore Programming
a) IP Spoofing
b) Web spoofing.

the fire. Write a program to implement the system using WSN and Different data
communication strategies/ algorithms (at least two) to compare the reliability of the data
received and efficient timing. Use of Fort Forwarding/Tunneling Protocol is expected.

Detecting copy-move forgery in images
This time I`ll talk about
digital image forensic and how to detect copy-move forgery in images.
I`ve implemented some ad-hoc algorithm for detection of this kind of
forgeries. Algorithm is robust, so it can detect forgeries in lossy
image formats- such as JPEG. Please keep in mind - this algorithm is
experimental toy, if you want more general solutions - you should read
this paper or maybe this to get some ideas in the field. BTW, this
algorithm is only tested with Python 2.6, so you better install Python
2.6.
Robust detection algorithm steps
1. Blur image for eliminating image details
2. Convert image to degraded palette
3. Decompose image into small NxN pixel blocks
4. Alphabetically order these blocks by their pixel values
5. Extract only these adjacent blocks which have small absolute color difference
6. Cluster these blocks into clusters by intersection area among blocks
7. Extract only these clusters which are bigger than block size
8.
Extract only these clusters which have similar cluster, by using some
sort of similarity function (in this case Hausdorff distance between
clusters)
9. Draw discovered similar clusters on image
Copy-move detection script usage instructions
Run script from the command line - cmd in Windows or terminal in Linux.
1. At first try to execute script with default parameters-
python detect_copymove.py image_file.jpg
2. Then try to lower block color deviation threshold-
python detect_copymove.py image_file.jpg --blcoldev=0.05
3. Finally - run script in manual mode and try to spot similar regions by eyes-
python detect_copymove.py image_file.jpg --blcoldev=0.05 --imauto=0
If
by trying all 3 steps - no copy-move tamperings revealed - there is a
good chance that really there are no such tamperings in image. BTW,
script has more parameters, full list of them -
python detect_copymove.py --help

INSTALLING NS3 IN UBUNTU 12.10
once ubuntu is installed run following command opening your terminal(ctrl+alt+T).
To install prerequisites-
sudo apt-get install gcc g++ python python-dev mercurial bzr gdb valgrind gsl-bin libgsl0-dev libgsl0ldbl flex bison tcpdump sqlite sqlite3 libsqlite3-dev libxml2 libxml2-dev libgtk2.0-0 libgtk2.0-dev uncrustify doxygen graphviz imagemagick texlive texlive-latex-extra texlive-generic-extra texlive-generic-recommended texinfo dia texlive texlive-latex-extra texlive-extra-utils texlive-generic-recommended texi2html python-pygraphviz python-kiwi python-pygoocanvas libgoocanvas-dev python-pygccxml
(now make sure you have not run sudo su to be superuser)
Downloading NS-3(ns-3 version 3.19 not 3.13)
cd
mkdir ns3
cd ns3
wget http://www.nsnam.org/release/ns-allinone-3.19.tar.bz2
tar xjf ns-allinone-3.19.tar.bz2
cd ns-allinone-3.19/
ls
Then you can find build.py along with other files.
Then to build the examples in ns-3 run
./build.py --enable-examples --enable-tests
If the build is successful then it will give output
"Build finished successfully".(clap for yourself)
Now run the following command to configure with waf(build tool)
./waf -d debug --enable-examples --enable-tests configure
To build with waf(optional)
./waf
To test everything allright
./test.py
If the tests are ok the installation is done. :)
After installing ns3 what to do??
make sure you are in directory where waf script is available then run
./waf --run first
and you will probably get
At time 2s client sent 1024 bytes to 10.1.1.2 port 9
At time 2.00369s server received 1024 bytes from 10.1.1.1 port 49153
At time 2.00369s server sent 1024 bytes to 10.1.1.1 port 49153
At time 2.00737s client received 1024 bytes from 10.1.1.2 port 9
then you can replace first by second,third till seven to get different outputs.note that you are running files of directory ../examples/tutorials which are of .cc extension but you have not used .cc in your command.
Next thing you need to know is put your programs in scratch directory so that you have not to make entry in wscript file.for eg copy availabe prigrams in scratch directory using different filename and try to run them.
ok the above information can also be found in ns3 tutorial but more important points for you can be:
1)ns3 can be used to generate .xml, .pcap, .csv, .dat files.
2)Netanim will be used to visualize your output that will use .xml file.
3).pcap is packet capture file you can open it using wireshark or tcpdump.
4)you can open .csv by just double clicking it(by Libre office).
5).dat is just your file to store data that can be used by .gnuplot script written by you to generate different graphs.
if you are new to netanim, gnuplot or wireshark don't panic i will probably write some intro that will help you to get started with them.
