I think we're beating a dead horse.
The purpose of this thread is becoming a useless increasing of the poor Mathematics and Algorithms forum.
I don't bother if your technique is new or old. I'm just wondering if your algo is able to accomplish the task (the way you claimed) or not.
Now, IMHO there are the following alternatives:
(1) You want to keep your algo secret.And you don't want to give any
evidence of its results.
(2) You want to keep your algo secret, But you want to give some evidence
of the results.
(3) You don't want to keep it secret.
Under (1) hypothesys, we should stop to beat the horse.
Under (2) one, you can provide us a text file with hidden info inside and the original file (without the hidden info inside).
Under (3) hypothesys, you may tell us about you prodigious algo or even write an article on the argument.
BTW I can't give you a prize for the innovative idea, It is not my role.

Well Sir,I will take the second option.But You wont be able to notice any difference whatsoever between the files using any text editor(I have used MS-WORD,WORDPAD,NOTEPAD).
My point is...the softwares that are avaiable to hide data in a carrier file...they change the file size,and the changes are visible using any simple text editor.But in my technic...u wont notice any change whatsoever using any text editor.

OK. Now, where are the two files?

You have beared with me so long...plse bear with me a little more and give me a day plse.
Sir onemore thing...if u cant notice any change in any of the readable/printable change using MS-WORD/WORDPAD/NOTEPAD using UTF-8 encoding,do u think the change can be noticed using other editor.If so can u plse refer me some text editor and where can i download them?If i am wrong i will sincerely beg ur apology to waste ur valuable time.
Sir,I am a novice in compared to you n software development.I am just knocking ur door just to be sure if i am right.I dont have any other intention whatsoever.

Take you time. I'll be waiting for.

Don't worry, you will receive all my comments and suggestions.
Good luck and have a nice day.

One thing you're ignoring that the space character IS a READABLE/PRINTABLE character. Just replacing the space with some other non-printable character is not going to work. At least, not within the parameters you've specified.
Seriously, with the spec's that you've laid out, what you want to do just isn't possible. There is simply not enough bits available to play with to make the technique usable for anything other than very short messages. This is why you just don't see the technique being used.

So, do you think he needs my approval?

No Sir...i am not using that approach.I am usin a very simple but effective approach.And using this approach...i am being able to hide the data in a text file without any change/replacement/distortion whatsoever in the readable/printable letters of the file and without changing the file size.

While you're listing a set of viable options (though in lost battle, IMHO), our friend keep talking about his occultism superpowers http://www.codeproject.com/script/Forums/View.aspx?fid=326859&msg=2474129[^].

If you have done it with techniques like Alternate Data Stream[^] , then it's not really data hiding. Please describe your idea.

Hmm, I know, but I don't know any Text-Editor that would not reflect the MSB-Bit set to 1.

then create a font that holds the ASCII char set twice, and make it the default font.

... and any more tricks, but this will hide the data only on his own box ...

No...I am not assuming ASCII codes to be 7 bit.

No Sir,I have not used the alternate data stream technique.

Can you plse tell me...is it something new if i can hide data inside a text file without changing the fle size even by a single byte and without replacing/changing/distorting any of the readable/printable letters of the file
|
|

Ok, to make a long story short:
I think, it's impossible.
I think, all necessary was said by parmfleet.
I think, it's a miracle (I don't believe in algorithm miracles).
In this sense, yes it's new.

Well Sir,if you comapare the text files(prior and post hiding data versions) bit by bit...there will be obviously some chages.But that change will have no impact whatsoever in any of the readable/printable letters of the file.Not even a single readable/printable letter will be changed/replaced or distorted.Plse note my emphasise on readable/printable letters.There will be some changes in the file in binary level.But,i say again that change in binary level will have no impact whatsoever in the readable/printable letters of the text file,the readable/printable letters will remain absolutely the same as they were before hiding the data.And the size of the file will also remain absolutely unchanged.The size will not change even by a single byte.
Considering the above...do u really think it's impossible?

Ok, so you change the text file at bit-level, of cource you can use this to "hide data". But consinder, text files are interpreted by editors (programs). Any editor may / may not react to your changes, and EVERY hex-editor / binary compare tool will notice the differences.
So the changes are not hidden, and the whole secret is based on your algorithm (of coding your data into bit-changes). Therefore it's not a secret at all.

Ya Every hex-editor / binary compare tool will notice the difference but my point is...I have tried some data hiding softwares.Those softwares encrypt the data using any available algorithm and hide the encrypted data in a file.But in all the cases...i have observed that...using only any text editor you will be able to notice the difference.In all the cases the size of the file changes and either the encrypted data is appended in the file or some readable/printable letter of the file is replaced/changed or distorted to hide the encrypted data.But my technic does not change the size of the file,does not append the data or change/replace/distort any of the printable/readable character of the carrier file.You wont notice any change whatsoever in the file content using any text editor.

That's the whole point. I don't believe that. How many different text-editors have you tried? Whats the text-encoding of your files?
Matthias

I have used MS-WORD,WORDPAD and NOTEPAD with UTF-8 encoding.
Can you refer me some other text editor and other encoding using which you can be proved right and where i can download them?
Look I am just a novice in comparison with you people.I am knocking ur door just to be sure,what i think is right or wrong ?

ASCII

In UTF8 you could have coded space (0x20) into hard space (0xA0), would give you 1 bit for hidden data per space in carrier file (assuming the original file don't have hard spaces). There are many more possibilities.
Thats all nice, but not really new.
