Steganography in text by using MS word symbols

The massive amount of data transfer over internet raises different challenges such as channel types, transmission time and data security. In this paper, we present a novel secure algorithm to hide the data inside document files, where four symbols are used to embed the data inside the carrier file. The main process depends on a key to produce a symbol table and match the data to be hidden with the representative symbols. This method can be extended to any language and does not change the file format. In addition, the capacity ratio of the presented algorithm is high compared to other algorithms.
