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.

Let me get this right. Your algorithm hides data in a file but doesn't alter the file in any way? Does it look anything like this?

Hiding information in text, isn't that what documentation is about?

It hides the data in a file and it does not change the file size and no visible change whatsoever in the file.
Your original post states 'the file will remain 100% unchanged'. If you're not changing the file, how can you be hiding data in it? What you're saying just doesn't make sense.

How can you make this claim? In order to hide the data, you are going to have to modify some characters in the file. If I use a diff tool to compare the old and new versions of the file, it's going to flag up some differences. If you make changes to a file, they're going to be noticed.

You're wrong. You wrote all the above because you're not aware of occultism superanatural powers. :-D

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

Hmm, I know, but I don't know any Text-Editor that would not reflect the MSB-Bit set to 1. :zzz: Matthias
then create a font that holds the ASCII char set twice, and make it the default font. :)

You read it wrong.I said AS FAR AS READING THE FILE IS CONCERNED,the file remains 100% unmodified.Ofcourse i have to make some modification but that does not affect the size of the file or for that matter the readability of the file even by a bit.
Do you know a text file contains just character codes?
