In short, the term steganography refers to the overall science of hiding information, whether this is in secret codes and cryptography, or any other element of privacy or confidentiality. If this is a subject that you are interested in learning more about, then you are definitely not alone in this curiosity. Because of all of the modern developments in technology, this scientific field is changing rapidly, and there is so much to be learned about the entire history of this science leading up until today.
In Printer Steganography there are various means of transferring information in a seemingly unnoticeable way. This is where the field differs from cryptography, because cryptography is obvious in that it is hiding meaning in some way, shape, or form, and lends itself more conspicuously to further consult. The chief aim of this science is not making information unreadable but rather hiding data from a third party. This can be done through digital means in ways that is incredibly simple compared to analog formats.
There are variety of softwares these days that make scrambling and decoding something incredibly easy to do between third parties but seemingly inconspicuous and jumbled to an outsider, but this is not the limit at all to what you can do. Spend some of your free time researching this fascinating field,and in very little time you will feel exposed to an entirely new world of information transfer in the Digital Age and what it means for everyone attempting to conceal data in new and meaningful ways.
