    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. Matthias

    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?

      Why don't you just tell that this would be indeed a first application and algorithm that would be capable of data hiding in the way he claims it to do?

I know very little about software development and i sincerely consider you people far more learned than me.That why i am just asking u people if this techniq has already been implemented the way i am claiming it.

        What do yo mean with. The file will change on a binary level.? And how wouldn't that have an impact on the readable Text portion of the file?

        Sir...can i ask you something? If a character is not readable/invisible in MS-WORD/WORDPAD/NOTEPAD using all the english (cause i have tried it only using english fonts) font,will you consider that character readable/printable?

          No, the technique the way you are claiming it, doesn't yet exist, because until now people didn't think is was possible. So you would be the first to create this algorithm.

            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. Matthias

                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. :)

                  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

                      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.

                          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 ?

                                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. Matthias

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.

                                        Text file contains only character codes.What if i can hide data inside the text file without distorting/changing/replacing a single readable character.

                                        Pallab: Your algorithm is unique if it really does what you say. I have a fair amount of experience with algorithms in general, and data compression and encryption in particular, and I've never heard of an algorithm that can do what you say. I'm not saying it's impossible; I've seen some very clever algorithms that do amazing things. You really shouldn't reveal the details until you get it patented. It potentially has value, and if you publicly disclose how it works you won't be able to patent it later. I don't know if you're in the US, but in the US you can get an inexpensive provisional patent that will give you a year to turn it into a more rigorous 20-year patent.

                                          Hi guys...I am from Bangladesh and my knowledge is very limited.I have developed an algorithm using which any data can be hidden in a text file.After hiding the data in the text file,the size of the text file remains absolutely unchanged and there is no change whatsoever in the file's content as far as reading the file is concerned.I know there r lots of data hiding techniques.Guys can you plse tell me if this techniq has already been implemented the way i have done it...I mean hiding the data in a text file without changing the file size even by a single byte and you wont see a single replacement/change/distortion in any of the letters of the file.As far as reading the file is concerned...the file will remain 100% unchanged even after hiding the data in it.

                                          Ok so lets break your claim into this: 1) hiding the data in a text file without changing the file size even by a single byte 2) you wont see a single replacement/change/distortion in any of the letters of the file 3) As far as reading the file is concerned...the file will remain 100% unchanged even after hiding the data in it. No problem with 1). I see problem in 2): "you wont see" and "letters of the file" and 3) "As far as reading the file is concerned...the file will remain 100% unchanged" "Text files are sequences of readable characters such as letters, digits, punctuation, or whitespace; and control characters such as section boundaries, rendering instructions for different languages, line feeds and carriage returns. Embedded information such as font information, hyperlinks, or inline images do not appear in text files, though references to them can be included within (such as HTML elements or metadata)." (http://en.wikipedia.org/wiki/Text_file[^]) If you replace letter with different letters that *looks* same in some font, file is far from unchanged. Sure, person looking at it in notepad or whotever might not notice, but as far as reading the file for text editor, that is a difference. Sorry but if this is your idea it's close to using white font on white background :)
