| Abstract | ||
| One of the methods used in security areas is steganography. Steganography is the art and science of hiding information by embedding messages within cover media without attracting attention. the cover media can be text, image, video or audio files. Text steganography is more difficult than others due to the difficulty in finding redundant information in text file. This paper presents a new idea for text steganography by using Unicode standard characters, (which have the non-printing properties) to encode the letters of English language and embedding the secret message letter by letter into the cover-text. This method has high hiding capacity, it can hide (K+1) letters in a text with K characters and it does not make any apparent changes in the original text. So it satisfies perceptual transparency. | ||
