Living Inside a Machine, a Security Discussion

Unlike the traditional non-life data, life data in a computer should be treated cautiously in order to prevent duplicates or deletions of lives. In this paper, firstly I introduce how a life comes up inside a computer, and then I give the representation of lives inside a computer. In the second part, I review the abilities and operations of a software system. And lastly, in part 3, I give discussions of security issues for lives inside a computer.
