Information hiding using whitespace technique in Microsoft word
Ooi Wei Liang, Vahab Iranmanesh · 2016
Steganography is a data hiding technique that allows data to be hidden behind another data such as image, audio, and text. Among these three common media, text steganography that is referred to hiding the secret message behind other text, is known to be the most difficult approach. This is due to its lack of redundant information, comparing to the other media such as image, audio and video to hide the secret message. To overcome this problem, a modified whitespace technique has been developed to embed the secret message within the text without significant changes on the text file. In addition, the proposed technique makes a degree of difficulties for the attacker to decode the secret message using random shuffled spaces between the word spaces and different key for embedding the secret message.
