Steganography

DRIVECRYPT uses advanced steganography to hide your confidential information into music files.

Steganography is the art and science of communicating
in a way which hides the existence of the communication. In contrast to cryptography, where the "enemy" is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of steganography is to hide messages inside other "harmless" messages in a way that does not allow any "enemy" to even detect that there is a second secret message present. Steganography is in the (especially military) literature also referred to as transmission security or short TRANSEC.

A good steganography system should fulfil the same requirements posed by the "Kerckhoff principle" in cryptography. This means that the security of the system has to be based on the assumption that the "enemy" has full knowledge of the design and implementation details of the steganographic system. The only missing information for the "enemy" is a short easily exchangeable random number sequence, the secret key, and without the secret key, the "enemy" should not have the slightest chance of even becoming suspicious that on an observed communication channel hidden communication might take place.

DRIVECRYPT is able to hide entire volumes in music files using advanced steganographic techniques. There are a number of simple software tools available for hiding files in the least significant bits of digital images or for transforming PGP messages into files resembling pure random byte sequences. However usage of most of the currently available steganographic tools might be quite easily detected using sufficiently careful analysis of the transmitted data.

If you want to test DRIVECRYPT`s advanced Steganography, please create a 16 bit, stereo audio file. (An easy way to do this is by downloading the program "WinDAC" from our Download Section. This program allows you to transform any song from any audio CD to a Steganographic-suitable wav file).
Then tell DRIVECRYPT to create an encrypted disk in the music file (by choosing the option "Use Cryptographic Functionalities" on the disk creation wizard.

The resulting music (WAV) file, created by DRIVECRYPT, will become a "virtual container" for the storage of confidential data, just as if it were a normal hard disk. For unauthorized users, however, the file will appear to be just a simple music file.

DRIVECRYPT is the most powerful, flexible and fast cryptographic program available on the market today, bringing Military Strength Encryption to your computer and protecting your data transparently in a quick, reliable way.
