Abstract
When encoding software, two or more encoding algorithms are employed. Conversely, for software decoding processing, decoding algorithms are prepared that correspond to these two or more encoding algorithms. Then, in software encoding processing, encoded algorithm combination identification information is transferred to the software decoding processing along with the encoded software. During software decoding processing, opposite algorithms possessed by the decoding means are selected based on the previously mentioned algorithm combination identification information, and the previously mentioned encoded software is decoded.
