Outguess Rebirth is an open-source steganography tool used to conceal messages within other files. It allows hiding information inside JPEG images without significantly changing the image's visual quality.
Outguess Rebirth is an open-source steganography program used to embed hidden messages within digital media files like images, audio files or even video files. It is a rewrite of the older Outguess 0.13b software which was discontinued.
Outguess allows hiding information inside JPEG images by imperceptibly altering the image data to store the message. It utilizes techniques like redundant pattern encoding and layered embedding to minimize visual changes and make the images look unsuspicious. The concealed information can later be extracted using the same Outguess tool.
Unlike many stego programs focused solely on messages, Outguess gives priority to preserving image quality and properties to avoid detection. The modifications it makes are subtle and the embedded data does not significantly affect the carrier image's size. This makes it suitable for covert communication purposes.
Outguess Rebirth supports hiding text, encryption keys, messages up to a megabyte or more depending on the image size. It runs on Windows, Linux and macOS platforms. Overall it is an actively maintained steganography tool to conceal messages in JPEG images.
