What is more, you can use Outguess to extract the hidden file from an image file via the Extract tab.

On top of that, also from the Preferences tab, you can adjust the Key start and limit value along with Key derivations and JPEG quality. You can also configure Outguess to mark modified pixels and collect statistics information. Use your own custom encryption keys to make sure that your data is safe at all timesīy accessing the Preferences tab, you can type in the encryption key, enable the second file feature along with the error correction option. You just have to select the file you need to hide, the desired image and click on the “Hide” button to conceal your data. Outguess is an advanced steganography utility that provides the necessary tools and features to hide your files inside pictures with just a few mouse clicks. Steganography is the art and science of encoding hidden messages in such a way that only the sender and the recipient can decipher the message.īesides concealing the content of the message, steganography is also concerned with hiding the fact that a secret message is being sent. Use images to hide information in plain sight By altering the seed, OutGuess tries to find a sequence of bits that minimizes the number of changes in the data that have to be made.If you want to securely send sensitive information to friends, or you just like to hide files, messages and documents from prying eyes by using steganography, then you should definitely try Outguess. It is embedded in the data along with the rest of the message. A seed can be used to modify the behavior of the iterator. OutGuess uses a generic iterator object to select which bits in the data should be modified. Before embedding data into an image, the OutGuess system can determine the maximum message size that can be hidden while still being able to maintain statistics based on frequency counts. As a result, no known statistical test is able to detect the presence of steganographic content. For JPEG images, OutGuess preserves statistics based on frequency counts. Although the secrecy of the information is not degraded, its hidden nature is revealed, defeating the main purpose of Steganography. This allows an eavesdropper to detect media that has been modified, revealing that secret communication is taking place. Because of their invasive nature steganography systems leave detectable traces within a medium's characteristics. Classical steganography systems depend on keeping the encoding system secret, but modern steganography are detectable only if secret information is known, e.g. Steganography is the art and science of hiding that communication is happening. Please see each source file for its respective license. It is completely free for any use including commercial. OutGuess is available under the BSD software license. In the next paragraphs, images will be used as concrete example of data objects, though OutGuess can use any kind of data, as long as a handler is provided. In this version the PNM and JPEG image formats are supported. The program relies on data specific handlers that will extract redundant bits and write them back after modification. The nature of the data source is irrelevant to the core of OutGuess. Niels Provos OutGuess is a universal steganographic tool that allows the insertion of hidden information into the redundant bits of data sources.
