steganography

bmpPacker - added 2/21/2007
bmpPacker is an steganographic encrypting software which uses a very common graphic file format as a data container. The resulting file is a bitmap file which is 100% compatible to the Windows BMP format.

Steghide - added 10/26/2006
Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests.

Digital Invisible Ink Toolkit - added 10/26/2006
The Digital Invisible Ink Toolkit is a Java steganography tool that can hide any sort of file inside a digital image (regarding that the message will fit, and the image is 24 bit colour). The tool has the additional advantage of being able to simulate hiding - so you can get an accurate map of where the information is hidden.

GRL RealHidden - added 7/6/2006
GRL RealHidden is a software utility that allows you to hide a file physically inside of another file, and then retrieve that hidden file. The resulting ‘cloaked’ file, that is the file containing hidden file, usually operates exactly like the original file! This exciting product gives you the power to send and receive files that contain hidden information, and the peace of mind to know that even if the files are interecepted a third-party probably would not know that they contained hidden information. In order to keep the final file size a low as possible, GRL RealHidden gives you the option of compressing the hidden file.

Sekritz - added 10/31/2005
Steganography is the art of ensconcing information meant to be secret. Unlike cryptography, steganography makes an attempt to conceal the information in plain sight. Instead of creating an incredibly new and annoying encryption algorithm, steganographers will keep the original message intact, however, hidden from the unsuspecting eye. Sekritz is a simple, intuitive program to hide sensitive data in files using steganography.

JPHS for Windows - added 12/8/2005
JPHIDE and JPSEEK are steganography 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 concealed by steganography.

CameraShy - added 1/7/2006
Camera/Shy is the only steganographic tool that automatically scans for and delivers decrypted content straight from the Web. It is a stand-alone, Internet Explorer-based application that leaves no trace on the user’s system and has enhanced security.

Stegdetect - added 12/31/2005
Stegdetect is an automated tool for detecting steganographic content in images. It is capable of detecting several different steganographic methods to embed hidden information in JPEG images. Stegbreak is used to launch dictionary attacks against JSteg-Shell, JPHide and OutGuess. Given a set of normal images and a set of images that contain hidden content by a new steganographic application, Stegdetect can automatically determine a linear detection function that can be applied to yet unclassified images.
