This is a relatively new field, since the new technology behind steganography is just becoming popular. Steganalysis is simply the detection of steganography by a third party. There are also several others such as S-tools. It determines the maximum amount of information that can be inserted into a jpeg without changing the statistical counts, making it difficult to find using statistical tests. Outguess is one such program, it is a universal steganographic tool that allows the insertion of hidden information into the redundant bits of data sources. There are also several different programs, with their own methods that all fall under one of the above mentioned categories. Generation creates an entirely new file, based around the information that you want hidden, for example, creating an image of a painting based on the bits that are in the file. Substitution finds the least significant bits, and places the hidden document there. With injection, the idea is to find areas in the file that are not being used, like at the end of a song for example, and insert the data in that space. There are three basic ways: injection, substitution, and generation. Not only are there several programs that hide information, there are several different methods for doing so. It is not always used in a malevolent manner, some people just like to keep their private information secret, or use it as another way to encrypt important information, but the fact is that it can be used in a criminal way, and that is what the concern is about.

There are over 100 free steganography programs, such as Outguess, available on the internet, and it is reported that there have been over 1 million downloads of this software, which goes to show how popular steganography is becoming.
The problem is, there are so many methods to embed the information, it is hard to develop programs to distinguish between the different types. This is why there is now a growing interest in steganalysis, which is the detection of embedded data. It has become a threat not only to individuals and businesses, but to government agencies and homeland security, not just in the United States, but all across the world. It has been used for terrorism, fraud, espionage, etc. Most of the attention has been drawn now because of the malicious use of the technique. Steganography has become increasingly popular in the past years, due to the explosion of the internet and multi-media use in general. Now, steganography is the altering of bits in either an image, sound document, or even another document, to hide a message. Steganography has come a long way since those days. They also used invisible ink, null ciphers, and microdots to convey messages. Another technique that was used was etching a message in a wooden tablet, and then covering it with was.
