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_GT

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

Pallab_GT

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

Then your claim is obviously false. Common sense dictates that data cannot be hidden in a file without requiring the file to be modified. If the file is modified, a diff tool will pick up the changes. If you still believe your claim is true, you are more deluded than I first thought. If you want to perform miracles, maybe you should consider changing careers and become a magician instead of a software developer.

You are missing one point again and again...i am insisting upon the fact that i am not going to change/replace/distort any of the READBLE CHARACTERS. Before u pass comment u should know that it is not necessary that you will know each and every trick of software development.There might be things beyond ur knowing.One more thing...No body in this world knows everything.

All characters in a text file are readable. That's the whole point; data is stored in text files so it can be read by humans as well as computers. Have a look at the ASCII table[^]. Notice anything? That's right, all the characters are human-readable. Now ask yourself this: if all ASCII characters are readable, what changes can your algorithm make that won't be easily noticed?

And what are the UNREADABLE CHARACTERS of a text file? I have to admit I know only a few tricks of software development :sigh: , but I'm striving to learn :rolleyes:

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

Pallab_GT

Sir,my knowledge of software development is very limited and you know a lot more than me. I will definitely share my idea...tell me...will it be something new if i can do what i claim? Aspects of my idea- 1.All readable/printable letters of the text file remains absolutely unchanged 2.The size of the file does not change even by a single byte after hiding the data.

Pallab_GT

Sir,my knowledge of software development is very limted.I am a novice in comparison with u.I know u know a lot more than me. Can you plse tell me will it be something new if i can do what i am claiming to do?

Not only will it be new, it will be a miracle :rolleyes: Haven't you learned anything from this discussion? You want to hide data in a text file without making noticeable changes. I have demonstrated to you that any change you make to the file is noticeable. Therefore your objective is impossible.

all the bytes between the logical end-of-file and the physical end-of-file is unreadable to the normal application associated with the file type. It can range up to an entire disk cluster (that is several sectors) without being noticed. :)

Pallab_GT

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.

CPallini

OK, now put your text file on a floppy or perhaps transfer file content on a network. :)

Tell me will it be something new if i can prove what i am claiming?

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[^]. :-D

Do you need my approval?

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

Pallab_GT

Sir,My knowledge is very limited in compared to you.So i want to know if i can do what i am claiming...will it be something new?

BadKarma

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?
