With the electronic signature law and related laws now being put into effect, evidence-making based on digital signatures is about to come into widespread use in society. Methods for making digital evidence have not been established, however, for several important areas such as long-term maintenance of digital evidence. The authors believe that evidence can be basically classified into that which is legally authorized and that which is not, and that making a clear distinction between them will help to accelerate research and development of digital evidence-making systems.
