Steganalysis is the process of recovering hidden data, It decides the encoded hidden message, and if conceivable, it recovers that message. The message can be identified by taking a gander at changes between bit designs and unusually large file sizes. Trustwave security said,One of the problems that we have these days is that there are not a lot of tools that include steganalysis modules, so it is a little difficult to protect our networks from this kind of attacks. The easiest approach is to run a steganalys suite in one of our devices which analyzes the files that are attempting to leave the intranet.”]
