Outguess: Open-Source Steganography Tool
Open-source steganography tool for hiding data within image and audio files, allowing safe data transfer between parties
What is Outguess?
Outguess is an open-source steganography program that allows hiding data within various kinds of image and audio files. It utilizes techniques that embed hidden information into the redundant bits of data sources. The intended use is for securely transferring information between parties.
Outguess works by examining the redundant bits of data sources to determine which bits can be safely used to hide data. It can hide information in the least significant bits of JPEG images and WAV audio files without increasing their file size. This makes it difficult to definitively detect that steganography has taken place.
Some key features of Outguess include:
- Hiding data in JPEG images without changing their visual appearance or file size
- Embedding information into WAV audio files while preserving audio quality
- Encryption of messages before embedding them for added security
- Preservation of histogram to minimize chance of detection
- Support for embedded error correction codes
Outguess serves well in securely transmitting messages, maintaining anonymity, or protecting sensitive information transfers. Its open-source nature allows community development and review of its steganographic techniques.
