In this method a new proposed approach to hide English texts (Secret data) in the Arabic text (Covers media). The secret text will be passed through several steps, Eventually it will be embedded in the cover text. In the proposed coding step each English character is converted to the binary code through secret tables that exist on the two sides (sending and receiving), which give us compression data. The output from the proposed coding will be two parts and these parts will be input to the next steps. The next step is Modified RNA Codon (MRNAC) which takes the first part that result from binary code and returns a stream of binary to be ready for embedding in embedding step. After that Modified Run Length Encoding (MRLE) that takes the second part that results from the proposed coding method and this result always contains a sequence of ones with fewer zeros, and apply RLE to this result. The last step is the embedding step using specific Arabic Unicode characters and non-printed characters to embed the secret information and provide complete similarity between cover text and stego text since these characters dont appear when written.
