English Abstract

I’ve been in this research study methodology for hide data within different texts.

That's where the data masking process is one of the areas of information security to hide and encrypt data and other branches that represent information security.

That to hide the data multiple ways as hide data within an image or within an audio file or within the text, where the hide data within these means check the interest of protecting the rights of publication and copyright or non-arrival of unauthorized to this data easily, the fact that these hidden data is characterized by secrecy and privacy.

The process of hiding data within the text are completely different from the rest of methods of concealment, it will be through a change in the empty spaces in the text or change the text itself or change in some of the properties other than text and empty spaces.

These changes are a way by which to hide data within the text.

This thesis proposes an enhancement of white space method for hiding data; which is processed by changing the secret text through extracting the indexes of the characters from the cover text or ASCII code , then converting these numbers from the decimal numeral system into the octal numeral system in order to use the number 8 and 9 as indicators against the remaining numbers.

As placing the number 9 before the extracted number indicates that it is an index of a character.

and placing the number 8 before the extracted number indicates that it is an ASCII code.

Then, merging these outcomes with the white spaces between the words in the cover text by changing the font size of these numbers to 1pt, and changing the font color to match background color of the cover text.

I’ve been in this research verification of the proposed process in enhancing the technique of open space methods to hide the data - text under text, and have been verified three basic things: the speed of the hiding data process, the size of the output text of this process, as well as to verify that the text resulting from these process is identical to the original text, which has been used to hide data under it.
