| Research Abstract |
Steganography is a information security technique, which security is realized to hide the existence of secret information in some other data (we call it a dummy data). We have proposed a steganographic technique, which is called BPCS-Steganography, which information hiding capacity can be as large as 50% of the dummy data. In the present research, we consider the applications of BPCS-Steganography and make the prototype software for those applications. Detailed items of the research and its results are the following.
1. A steganographic technique that uses color images as the dummy data and the prototype software for email:
We have made the prototype software that works on Windows and has easy operations in embedding and extracting. Before the research, we had made the software having some bugs. The prototype software is improved the problems and stable.
2. A steganographic technique that uses audio data as the dummy data:
We have proposed a embedding method that uses the size or the amplitude or the dummy data. WAV file format is used for the dummy data. We have also made the prototype software for the steganography.
3. A steganographic technique that uses printed images as the dummy data:
We have extracted the secret information embedded into printed image. Detailed steps are the following. First, we embed the secret information into the dummy image on the computer. The dummy image is printed out on a plastic board which is just business card in size. The printed image is scaned by scanner and then the secret information is extracted.
The above third topic is the most interesting area in the future reseaches in connection with BPCS-Steganography. It is possible to apply the method to many industrial applications if the embedding capasity becomes larger.
