What are different types of steganography tools?
In addition to encryption of messages that protects the content of the message, it is often desirable to hide the very existence of the message. Steganography is a science of data hiding within data, so the message itself is not easily found. Some types of steganography tools include text tools that hide messages in texts; coding packets of IP to file headers; and hiding messages in pictures or audio files.
There is a wide range of text stenographic tools. These are usually low-technical methods in which the text is arranged, formatted or selectively selected to reveal some hidden meaning. As a simple example, the normal steganographic scheme includes a fixed letter selection from each word in a common message to create a hidden message. Another option involves overlapping a mask over a blurb text to reveal the letters or words containing a hidden message.
Unused Bits of Internet Protocol (IP) in Open Systems Interconnection (OSI) can also be used as a steganography tool. NiWaters can take advantage of unused IP headers in the OSI network layer, such as the don't fragment (DF) or multiple fragments (MF), and create a hidden channel to transmit information in OSI data packets. One of the advantages of this approach is that packets are usually incoherent and mixed between the huge volume of other packets unrelated to reports. For example, if one packet between a million streaming packets contains elements of hidden messages, and among many such packets will disintegrate the hidden message itself, the discovery of the message would not be easy.
Image and sound steganographic tools have become very popular thanks to the Internet. Files of images and sound on the Internet are predominant and usually large enough to hide a lot of built -in content. Commercially available software can even exist to re -rair the least significant bit (LSB) bytes containing image and audio digital files to insert messages. Although changing these bits worsens the quality of the image or sound,Degradation is usually small enough to make it noticeable to the naked eye. However, this steganographic technique leaves a detectable statistical signature. Users can cover the signature by using the randomization of cryptographic measures, but a qualified cryptograph could probably detect it.
Steganographic activities in general are strongly supported by a huge volume of streaming data throughout modern society. Each part of this data current can bear hidden, built -in data. Steganographic security countermeasures are often stylized by the fact that while technology exists to control data flow for steganographic signatures, attempted it can slow the data flow so that it is not worth it.
