I'm completely lost; I know it's not contributing to the topic, but could someone just explain what we're looking for and what this steno doofie is?

Thanks

Steganography information.

...and Chris, couldn't agree more.

Cheers Jux, will check that in a min

Finished the others at a sensitivity of 3.00, this is what I found, note that not every page with a huge blank space comes up with something and neither james or miranda's do. Ive put the amount of stars that came up next to the jphide bit in xsteg, so someone that is faster at this can probably beat me to it!
(If someone wants to double check this because this is the 1st time I've done this.)

Anyway

All Anatomical reports came back with a (jphide*)
Comms report page 001.jpg, (jphide*)
Forensic page 001.jpg, (jphide*)
Heidi's witness statement page 001.jpg, (jphide*)
Heidi's statement page 000.jpg came back as an error in JPG datastream?????
Sente (OOOO ) page 000.jpg, (jphide***)
(Even more ) Violet page 000.jpg, (jphide*)

All others came back negative.

Kiz, stegging works by hiding information in the file itself. If you take a JPG and save the image as a bitmap, I'm pretty sure any hidden information would then be lost.

For gods sake....i spelt things the same way as i say them in real life! i dont say "what would you like me to do" id say "so what ya want me to do now?" anduyoujump me for txt speaking !!! the "b othered" was because i hit the space key by accident !! and i dont say "got to" i say "gotta" thats not txt speak, its how I and the majority of people in essex actualy SPEAK ! Just like someone from birmingham using a word that means something there and is common, but means nothing here ! THIS is text speak:

"so wot ya doin? i tink il go shopn 2day n grab a few lfs of bred 4 lnch 2day"

Can you REALLY not see the difference between how each county speaks (and sometimes spells) things, and txt speak ? Ive already tightened up my spelling and grammar more since last night because of certain few complaining, and now you are asking me to spell completely different because a few of the older members of the site dont like it !

Sorry but its how i speak and type. Its NOT how i txt, because THAT would annoy you and i dont need to touch type on here.

This is gettin really silly now, and is continuing from last nite on IRC it would seem. Get over it, please

As for steno...yeah thats a good point, but cant find a JPG steno programe anywhere, wanna point me in the right direction? Steno sounds more lightly after the whole JPHide thing.

[psyche]

Am I right in thinking that steg files all need a password to extract the information? So we're looking for a password to crack that Sente file?

* from outburst of kiz there*

Moving swiftly on....

Ive tried the steg programs that are on the wiki and to be honest I couldnt make them work apart from the xsteg gui program. (Which gave me what I posted earlier)
So after Juxta's link help I downloaded a couple more, Digital Ink's program is good but you can't use a file bigger than 500 x 500 pixels. I found another called Revelation by a New Zealander which seems useful until it sends an error message saying it doesn't like compressed images... Which is what JPG's use........
So I'm gonna leave it for now, I expect I will come on later to find someone has managed it!

Have fun!

Yes, I can recognise the difference between different languages. As most people here understand English I write in English. If I were in France I would attempt to follow the general rules so people understand me easily.

You're not speaking, you're writing. As there are fewer resources available to you while you write it's more sensible to adhere to some basic rules of grammar and spelling to ensure that everyone understands what you're saying easily.

All you seem to be saying is "I'm SO special I don't really care if it's difficult for you people to understand me. I just don't care".

It's the linguistic equivalent of defecating on my face.

What tool are you using

[locqust]

Ah sorry have should mentioned that earlier, I opened them in photoshop and changed the colour palette to RGB mode instead of greyscale, then resaved it under the same conditions it was given to us. So I havent messed around with compression ratios or anything.
However thinking about it, could this mean that by me changing the palette I have introduced something which wasnt there before that xsteg recognised as a potential jphide?
Although if thats the case why hasn't it shown the same results on all pages or all the same types of pages? i.e all the page 2's with a huge blank space at the bottom.

[Crane]

Actually, I thought Stegging basically worked by minutely changing colour/shade values for certain pixels, so the info is actually IN THE IMAGE, not the file.
Am I wrong?

Thanks for the link Juxta.

Chris if it bothers you, just do what I do, skip over it! If someone can't write properly the chances are they can't bring anything new to the conversation! Although I can write properly, but still can't contribute to this, so my logic may be flawed!
