description
Steganography is the ancient practice of stashing secret text, images, or messages inside a different text, image, or message. Now In Digital communications Steganography Technique is applied to hide Digital Data In Images, text, messages. As far as security systems are concerned, the convergence of the translated pixels into their initial locations, i.e., image exact reconstruction after some iterations, is also not an appealing factor. This is an observed phenomenon in a variety of chaotic based algorithms. Given one of the iterations is used, if an attacker gains knowledge of the algorithm and obtains the parameter "\", which is actually not difficult to crack using a brute force attack, the attacker will be able to add further iterations which will reveal the original image However there are several algorithm that helps to hide data according to steganographic techniques, Different Algorithms are used in Embedding Encryption in Data i.e. DES( Data Encryption Standard), AES( Advance Encryption Standard).

HIDING DATA IN NOTEPADBYSYED UBAID ALI JAFRIVirtual Securityhiding data
STEP -1 : Open command prompt "cmd.exe"
STEP -2: TYPE :echo I Dont want this Message to be appear >Data.txt:Hidden.txt
echo - Command used to print dataI Dont Want this Message to be appear - Content of the File> - Symbol used to Write the data content.Data.txt - Write the content print by the Echo command in Data.txt: - There is a concatenation of a fileHidden.txt - Hide the data in Hidden.txt
Retrieving the Hidden Content of a file
To view the hidden content of the file Type:more < data.txt:Hidden.txtMore : Command used to read the content of the file< : Write the Data in the More cache memory:Concate the fileHidden.txt : This is a password file if we forget this filename then we will not be able to retrieve it easily.
Hiding Other File Types:TYPE[data to be hidden]>[target file]:[Alternate stream]For example: TYPEPasswords.doc>My_Pic.jpg:MyPasswords.docwill fork My_Pic.jpg with an ADS MyPasswords.doc.
Hiding .exe File :Even exe file can be hidden and *directly* accessed through ADS. For example :C:\>TYPE Virus>test.txt:MyVirus.exe
C:\>START .\test.txt:MyVirus.exe
(2) Removing attached ADSNow, suppose you want to delete the alternate data streams from a file without deleting the file itself. So, what you do is you copy the original contents to another file and then delete the original file, which would also delete all ADS. For example :
C:\> REN test.txt temp.txt
C:\> TYPE temp.txt > test.txt
C:\> DEL temp.txt
To View what ADS stream is being used with the text file TYPE DIR /R in the command promptFor example:"DIR /R" command in vista to show Alternate Data Streams
