OpenStego is an open-source software distributed under the terms of the GNU General Public License v2.0.
OpenStego provides two main functionalities:
- Data Hiding: It can hide any data within a cover file (e.g. images).
- Watermarking (beta): Watermarking files (e.g. images) with an invisible signature. It can be used to detect unauthorized file copying.
Features:
- OpenStego is written in pure Java and should run on all platforms supported by java. It has been tested on MS Windows and Linux, but should not have any problem on other platforms too. Please report bugs if you find any.
- It supports password-based encryption of data for additional layer of security. DES algorithm is used for data encryption, along with MD5 hashing to derive the DES key from the password provided.
- It uses a plugin based architecture, where various plugins can be created for different kind of Steganographic / Watermarking algorithms. Currently, it supports two plugins – RandomLSB (Randomized LSB) for data hiding and Dugad’s algorithm for watermarking, but new plugins can be easily created for other algorithms. Plugins can also be easily added for other type of cover files like Audio files.
