Digital Stenography

Digital Stenography java project report is the art and science of invisible communication. This is accomplished through hiding information in other information, thus hiding the existence of the communicated information. The word stenography is derived from the Greek words “stegos” meaning “cover” and “grafia” meaning “writing” defining it as “covered writing”. In image stenography the information is hidden exclusively in images. Digital Image Stenography system allows an average user to securely transfer text messages by hiding them in a digital image file. A combination of Stenography and encryption algorithms provides a strong backbone for its security. Digital Image Stenography system features innovative techniques for hiding text in a digital image file or even using it as a key to the encryption. Click here to get complete JAVA projects lists.

Conclusions

Digital Stenography java project report The meaning of Stenography is hiding information and  the related  technologies.  There is  a  principal difference  between  Stenography  and  Encryption; however they can meet at  some points too.  They can be applied together, i.e. encrypted information can be hidden  in  addition.  To  hide  something  a  covering medium is always needed (Picture, sound track, text or  even  the  structure  of  a  file  system,  etc.).   The covering  medium must  be  redundant;  otherwise  the hidden information  could  be  detected  easily.  The technology of  hiding should  match  the nature  of  the medium.
