Steganography Application for UTF8 Encoded Texts

Encryption is the most common method used to protect the texts from being read by the individuals or systems other than the sender and receiver. In encrypted communication, third parties and supervisors can easily realize that a closed information is transmitted. Although this content cannot be resolved immediately, it can be marked as suspicious. Closed text can also be protected by using a hidden method instead of using an encryption method. The hidden text could be attributed “innocent” without notice by the third parties or systems. Recognizing the hidden text will become more difficult when it is included in everyday conversations. In this study, the work of hiding another text within a text encoded in the UTF-8 standard has been made for everyday communication applications. The method used in the study has been controlled by using instant messaging softwares which are widely used.
