Steganography Tools

Blindside Blindside is an application of steganography that allows one to conceal a file, or set of files within a standard computer image. The new image looks identical to the human eye, but can contain up to 50k or so of secret data. The hidden files can also be password encrypted, to prevent unauthorised access to their data.
DataMark Technologies DataMark Technologies currently market four digital steganography products - StegComm for confidential multimedia communication, StegMark for digital watermarking of digital storage media, StegSafe for digital storage and linkage and StegSign for e-commerce transactions. Each software product is packaged into a Standard version and a Professional version. While the Standard versions cater to the general needs of our customers, additional security and accessibility features are found in our Professional versions. Please select and view the various product descriptions, and contact us for further information.
Digital Picture Envelope Digital Picture Envelope is a program you can make your secret data imperceptible to any human eyes. So, you can store/send it very safely in/through your computer. Actually, it can embed your secret data in a vessel image (we call it a "dummy" image, or a "picture envelope") without changing the visual quality of the dummy image.It does not change even the file size. If you want to see the secret data, you can easily restore it from the secret- embedded dummy image.
gifshuffle The program gifshuffle is used to conceal messages in GIF images by shuffling the colourmap, which leaves the image visibly unchanged. gifshuffle works with all GIF images, including those with transparency and animation, and in addition provides compression and encryption of the concealed message.
Hide4PGP Hide4PGP is a freeware program distributed as source code in ANSI C and precompiled executables for DOS (any version but 1.x - is there one outside the museum?), OS/2 (Warp and up), and the Win32 console (9x and NT). It's purpose is to hide any data in a way that the viewer or listener does not recognize any difference. This is called steganography.
InThePicture Encrypt Files & Messages into redundant space in Windows Bitmap (BMP) image files.
Invisible Secrets Invisible Secrets hides your private data into innocent looking files, like pictures, or web pages. It also features: strong encryption algorithms; a locker that allows you to password protect certain applications; a password management solution and a real-random password generator; a shredder that helps you destroy beyond recovery files, folders and internet traces; the ability to create self-decrypting packages; secured password transfer.
JPHIDE and JPSEEK JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the effects begin to become visible to the naked eye. Of course some images are much better than others when used a host file - plenty of fine detail is good. A cloudless blue sky over a snow covered ski paradise is bad. A waterfall in a forest is probably ideal.
MP3Stego MP3Stego will hide information in MP3 files during the compression process. The data is first compressed, encrypted and then hidden in the MP3 bit stream. Although MP3Stego has been written with steganographic applications in mind it might be used as a copyright marking system for MP3 files (weak but still much better than the MPEG copyright flag defined by the standard). Any opponent can uncompress the bit stream and recompress it; this will delete the hidden information -- actually this is the only attack we know yet -- but at the expense of severe quality loss.
NICETEXT NICETEXT is a package that converts any file into pseudo-natural-language text.
OutGuess OutGuess is a universal steganographic tool that allows the insertion of hidden information into the redundant bits of data sources. The nature of the data source is irrelevant to the core of OutGuess. The program relies on data specific handlers that will extract redundant bits and write them back after modification. In this version the PNM and JPEG image formats are supported. In the next paragraphs, images will be used as concrete example of data objects, though OutGuess can use any kind of data, as long as a handler is provided.
Scramdisk Scramdisk is a program that allows the creation and use of virtual encrypted drives. Basically, you create a container file on an existing hard drive which is created with a specific password. This container can then be mounted by the Scramdisk software which creates a new drive letter to represent the drive. The virtual drive can then only be accessed with the correct passphrase. Without the correct passphrase the files on the virtual drive are totally inaccessible.
Snow The program snow is used to conceal messages in ASCII text by appending whitespace to the end of lines. Because spaces and tabs are generally not visible in text viewers, the message is effectively hidden from casual observers. And if the built-in encryption is used, the message cannot be read even if it is detected.
SteganoGifPaletteOrder Hiding data into the palette of a GIF file.
Steganos Steganos hides secret information in sound, image, and text files. This sensitive data is being encrypted beforehand. That way files can be sent over the Internet without being discovered by a third party.
Stego Hide and recover encrypted data in your GIF files with Stego
StegParty StegParty is a system for hiding information inside of plain-text files. Unlike similar tools currently available it does not use random gibberish to encode data -- it relies on small alterations to the message, like changes to spelling and punctuation. Because of this you can use any plain-text file as your carrier , and it will be more-or-less understandable after the secret message is embedded.
TextHide Software to hide any data in unsuspicious text in order to store or communicate secrets (textual steganography).
wbStego wbStego is a tool that hides any type of file in bitmap images, text files, HTML files or Adobe PDF files. The file in which you hide the data is not optically changed. It can be used to exchange sensitive data securely or to add hidden copyright information to the file.
