I need some idea for my last project about Java

Hi my name is suzanna from Indonesia. I have lots of interest with Java programming and I want make something about it for my last project. It's very important and I need some idea...could u give me some topic? I'm sorry if my english is very bad.thx,bye

Here's some popular ideas:
image steganography, chat client/server, spyware, client/server file transfer, forum content management/enforcement, anything with reflection, anything with communicating with an external device such as camera or modem or robot, writing your own replacement for the java.util.Calendar class, anything with custom class loaders, splitting a string into a string[]
And for an extra challenge:
dominition-based repetition, implementing a JVM which represents 'null' values internally using some other integer value than 0

I want to get the web cam and hide the data using steganography method ?

i want to do steganography on web cam data, untill now i am able to do the video transmitting using jmf and now i am trying to get the actual video frame data and try to edit that and hide my secrete message. can anyone have any idea how to do this ?? i am a newbie in JMF please help me to get out of this stuff...!!!
thank you

For my senior capstone project, we had to hide binary data in a BMP image by encoding the bits into the LSB of the components of the pixel colors. You could do a similar thing with video data.
The above sample code demonstrates the concept of a custom Effect class... something that modifies a data stream. You can extend it to create two Effect classes, one of which that would write secret data, and one of which that would read the secret data.
Implementation details of how to get it working are up to you, but you can use the BufferToImage and ImageToBuffer classes to decode and encode the images into buffers.

Steganography

Hello,
I m new to java....I want to develop a project on steganography in java..
Our project will be on hiding textual data in bmp files...Please can anybody suggest me suitable compression and encryption techniques..
with appropiate API's to work on images..compression n encryption..
Thanks.
RichaSharma

As far as I know, the BMP format only supports RLE compression, which is supported by the Java libraries already.
As for encryption... do you want to encrypt the image itself? I would suggest that doing so defeats the whole point of steganography, since it tips off an attacker that something worth having might be hidden inside. Otherwise, the Java libraries also do encryption, if you would care to look over the API. If that's not enough, Bouncy Castle is pretty good, or Google will find more.

Steganography....algorithm

Hi!
I have to do a project about steganography.
I've searched on Google, but I didn't found too much.I'm looking for steganography algorithms, not necessary implemented in a language.
If you know some interesting links about this subject, please tell me...
Thanks!

Yes, sorry... :P
I've already visited the following links:
http://www.dreamincode.net/forums/showtopic27950.htm
http://forum.java.sun.com/thread.jspa?forumID=31&threadID=5157446
First of all, I've read something about the importance,use, history from ibm.com site, but I don't remember exactly the link...
I've heard too about a f5 algorithm:
http://www.ws.binghamton.edu/fridrich/Research/f5.pdf
I've searched sites about the algorithm, not about how to break it.
Hope I've wrote all the links...

Steganography in 3D Object (Image)

Hi,
Am doing a project related to steganography in 3D. I didnt find any source in net. Kindly any body tell me how to implement this in Java. am aware of steganography in image but, i dont have any idea to implement in 3D Objects.. Pls tell me any example program...
Thanks in Advance
Regards
Mekala

it looks like the extrusion is shallow and the spotlights may be directed downwards from above
(in which case the shadows may be down, beyond the edge of the canvas)
which 3D plug in did you use? Strata's?
I don't know much about 3D
just guessing
[and trying to get bucaca nervous in and about his own ignorance]

Steganography Application

Hi all,
im developing a steganography application in java as part of my final year project for college. when its done im going to need some people to test it and evaluate it honestly for me.
if anyones interested would they please post a reply and ill get them a developmental version soon.
Thanks guys+gals

Hi,
Steganography is the art of hidden writing, or hidden messages in modern terms.
The application i am developing uses the redundancy in image file formats to hide messages, maybe strings, other files or anyother digital media.
I know that steganography is not in your typical dictionary but then java developers are not your typical people either.
Thanks for your interest jboozer

Steganography implemented in Java with QIM Dither Modulation

Hello wondering if anybody can advise me on how to get started with this ?
I am starting a project where using Steganography as digital watermarking tool to insert text into an image.
I am using the quantization index modulation method with the colt maths package to implement the equations required. Any help would be much appreciated.
Thanks

G'day
I'm the author of the aforementioned steganography tool, the Digital Invisible Ink Toolkit. None of the techniques in the tool use QIM Dither Modulation, but they filter the image using edge detecting filters and use those filtered areas first - making it much much harder to tell where it is hidden.
If you're planning on writing an algorithm for steganography, and are happy to use the StegoAlgorithm interface in the tool, I'd love to include it with the program. My contact details are on the website, http://diit.sourceforge.net

TomAlthough not quite understanding what you ask, does it really have to do with 3D? Isn't that rather closer to 2D imaging, or "algorithms" for the calc... part? -> You might get bether (more?) answer there?

Digital Steganography: How to Build a VI for Academic Purposes

Hi,
I teach at a High School, and as part of the course the kids are interested in encryption. We discussed digital steganography and I wanted to be able to do a labview lesson where we discuss and write a VI. What I would like to do is have two VI's. One that writes data into a picture and in the process can change change color hues (if needed) and a second VI that compares two pictures to pull the differences out to reveal the hidden information. For my purposes it doesn't matter if the hidden information is binary or ASCII.
Our school has two versions of LabView. We have the education edition and we have the version used with the infinity project. (Both should have full functionality.) If there is any difference in the directions, education edition directions are preferred.
Sorry, but I have no idea how to begin this or what to do. I'm still new to and learning LabView as we go. I searched steganography and the other topics were not helpful. I would really appreciate any and all help.
Thanks.

While this is hardly military grade encryption I think you could illustrate your point with code like this.
Encode stage:
Decode stage:
This approach relies on the image being big enough to hold all the text. You could be more efficient if you use every color value (I only used blue to keep the diagram looking clean). The code isn't terribly robust (no error checking, doesn't check to see if there is space to encode the full message, etc) and I haven't tested it short of confirming that I could get a simple message back but it should help you on your way.
Good luck -- sounds like a fun class. I wish I got to do stuff like this when I was in high school.

Open project cancelled or unable to load database...

I have been running version 9 sucessfully and moving projects around with no errors. Today, I cannot load any of my projects.
I have been through the threads and deleted the .cpj, moved the project to the root of my hard drive, etc.
Something else is going on.
I did see some information on files being blocked by the virus scanner. I'll pursue that with my help desk.
Any other ideas would be appreciated.
Thanks!

The only file that is MS Access based is the CPD file and it does not matter which version of Access you have on your machine, indeed you don't have to have Access installed.
If you have the same problems with the supplied sample projects, then maybe something has gone wrong with your installation of RoboHelp. Click Open on the RoboHelp Starter page and then click Samples in the ribbon on the left.

I create a birthday calendar in iCal and then click on it in iphoto at the begining of the calendar project each year. Some how the birthday did not populate the photo calendar. Is there a way to add the birthday iCal calendar into the calendar project?

I created a birthday calendar to use in iphoto for calendar. When a new calendar project is started each year, I click on it in. Some how the birthday did not populate the photo calendar this year. The photo calendar is almost complete. Is there a way to add the birthday iCal calendar into the calendar project? I would prefer not to start over.

Hi,
If you first select the calendar on the left, so that its background is highlighted blue/grey, when you make a new events they should be added to that calendar.
Best wishes

Error in compiling Photoshop CC 2014 sample project

Hi,
I am trying to compile SDK sample project "outbound". but it is showing errors, as "Parse Issue: Unknown type name 'DialogPtr' " in DialogUtilities.h .
DialogUtilities.h file is in "Adobe Photoshop CC 2014:photoshopsdk:pluginsdk:samplecode:common:includes".
even if I add this path in project settings it still shows the errors.
how can I make this work?
I am using Photoshop CC 2014 and Xcode version is 4.6.3 (4H1503)
If you have any idea regarding project settings then please let me know.
Thanks and regards,
Priyanka.

Are you using the CC 2014 release of the SDK?
The DialogUtilities.h for mac do not work. They are the old Carbon API's. See the Dissolve example for an Objective-C UI.
I would comment out the DialogUtilities.h include and other associated headers for Carbon UI. Some Carbon calls still work that are unrelated to UI.

How do I use my third computer with cloud. I am rendering a project in Avid Media composer

How do I get my third computer to work with when I am rendering Avid project on the other two computers computers

Hi,
Running creative cloud on third machine will prompt you for the deactivation from last 2 machines. As per EULA for Creative cloud you can only install and work on 2 machines only, be it MAC-MAC, MAC-windows and windows-windows.
working on third machine without deactivation from previous machines is not possible.
Hope this helps.
Thanks

Mid month joiners PF Projection Issue

Hi Team,
We have an issue with respect to PF Projection for the employees who joined in mid month. We are on actual basis as an income tax projection.
Employee joined on 16.04.2014 and his basic is 20,000 rupees. Since he joined in mid month his PF will be deducted as 1200. Now the system is projecting under Aggregate chapter VI as 1200+2400*11 = 27600 which is incorrect. It should do as 1200+1200*11 = 14400
We are not sure why system Is behaving weird. If anybody come across this situation, please let us know.
Thanks and Regards,
Siva.

Hello,
Please note that proration in case of mid month termination and joining
will be applicable to PF eligible pay alongwith EPF basis.
This is the standard behaviour of the system.
Please go through the below explanation on the proration of PF
PF will be prorated if there is a mid month joinee or mid month
termination. In Case of LOP the Eligible Pay is not prorated.
If the pension basis is eligible pay which is maintained in T511P in the
constant PFBAS and currently having the value as 6500 then, in the case
of mid month joining 6500 gets prorated for the number of days employee
was in the trust.
In the case of mid month joining/leaving or transfer scenarios, the PF
Basis will be correspondingly prorated and so the contribution
calculated will also be prorated.
If the customer doesn't want this pension basis to be prorated then a
User Exit: Override Employer Pension Basis has been provided in payroll
function INEPF. The name of the exit is EXIT_HINCALC0_002. This exit is
in the enhancement HRINCEPF. We request you to go through the
documentation of this user exit at
Payroll India > Statutory Social Contribution > Provident Fund >
User Exit: Override Employer Pension Basis
With Regards,
Chetan
