摘要：Steganography is a secret writing wherein one person communicates with another without drawing suspicion to the secret communication through the medium. Text steganography is regarded the most difficult carrier to conceal secret data with because of its insufficient redundant information compared to image, audio, or video files. In this paper, we propose a new method for concealing information in English writing using non-printing characters, such as zero width non-joiner (ZWNJ) and zero width joiner (ZWJ). This approach uses to text steganography on text files. Secret information is embedded inside the English script using two-letter words based on their locations, hence achieving steganography. Results show that the technique satisfies perceptual transparency and information hiding capacity in the cover file by comparing with two previous developed existing methods. However, the size of the cover and stego document increases by approximately (22.61%) from the original size.
