STEGANOGRAPHY!



Ya... This is another method of hiding texts in websites... Font Color - White...
Steganography, deserves a post in my blog, as it is my first and extensively researched topic... The art of hidden writing, is followed by most of the people, including Osama bin Laden... Its said that, Osama is a Master in Steganography and he used text messages hidden inside pictures and uploaded these pictures in ebay website! Already, the website contains millions of pictures and finding these hidden ones is same as finding an oil drop in the ocean... But still, there was one US officer, (vetti paiyan) who searched manually each n every picture in ebay website and finally failed to provide a proof....
BINGO!
Here's an example of how to hide a picture inside another picture...
I used the software - S-Tool (272KB)
Hiding texts in websites is also Steganography!
U might wonder, what Harish's pic s doing in this post... @Harish, sorry buddy, din't find any other photo to experiment with... Also, the original photo was good, I made it serrated purposely, to hide the content better... Follow the following steps to see whats inside Harish... :P

1) Download the S-Tool Software... Its a very small application, no installation... Jus run it..

2) Save (the above) Harish's picture (filename - hidden.bmp) ... Drag the pic n drop it in the s-tool application window...

3) Right click on the picture, and click "Reveal"....

4) Give "harish" in the first 2 fields(password) and in the third combo box, select "Triple DES"

5) Voila! It'll show the revealed pic's filename.... Right click it and save it and see the pic...

Leave a comment, what u find inside harish...

Note that, we've steganographic techniques even with audio n video formats... And its practically impossible for someone to know the hidden secret content... Hence Steganography is considered to be more secure than Cryptography...

(To harish: Wish u good luck in Patni! Hope to see FPP soon!!!)

P.S. There are some more hidden stuffs in this post... Can u find it out????? Leave a comment if u can find it out!!! Lets see who finds it first...

P.P.S. Don't break ur head, thinking what could be hidden... Its just a simple technique to hide stuffs... Nothing technical...
