چکیده مقاله:
Steganography is the art of hiding data with the goal of communicating in a way that one can transfer a secret message through a cover data without raising suspicion. The cover message can be in form of text, audio, image or other kinds of data. Due to lack of available redundant information, using text as cover message is considered harder than using other types of cover messages. In this paper, we propose an algorithm for steganography in Persian text using ZWNJ and optimizing it. As it is an invisible character, we try to place some ZWNJs in the text in a way that transfers a meaningful secret message. We will show that with a large enough cover text, we can hide a secret message by making minimum changes in the file. Our last method has about 36% capacity, which is a very high amount.
