Features:

  1. High-quality palette generation using a combination of vector quantization algorithms.

  2. Unique adaptive dithering algorithm that adds less noise to images than the standard Floyd-Steinberg.

  3. Easy to integrate with shell scripts, GUIs and server-side software.

  4. Fast mode for real-time processing/large numbers of images.

Synopsis: `Hide' (nonconfidential) data in image or audio files
Description:

Steghide is a program to `hide' data in various kinds of image and audio files. This practice is known as steganography, but the method used by steghide is not very secure and should not be used where security is at stake. Even if a password is used, steghide offers little plausible deniability.

Nonetheless, neither color nor sample frequencies are changed, making the embedding resistant against first-order statistical tests not aimed specifically at this tool.
