Different strategies were introduced in the literature to protect data. Some techniques change the data form while other techniques hide the data inside another file. Steganography techniques conceal information inside different digital media like image, audio, and text files. Most of the introduced techniques use software implementation to embed secret data inside the carrier file.
This is while software implementations are not sufficiently fast for real-time applications. In this paper, we present a new real-time zero-width-character (ZWC) Steganography technique to hide data inside a text file using a hardware engine with 6.415Gbps hidden data rate. The fast Steganography implementation is presented in this paper.
