Conversion
of the securities
In our system, any entity can issue securities as a local currency. Let
V
S
and
V
R
be
the value vectors for a service and a reward, respectively. Let
be the conjunction
of parts of the value vector.
V
R
could be divided into three parts shown in Fig.

where
V

are the value vectors of the first, second and third, respec-
tively. For example
V

12.7.4 Credit of the Securities
12.7.4.1 Reputation of the Personality
Outline of the Method
The reputation of the entities consists of two parts. One is evaluated by the
performance history of the securities issued by the entity. The other is the subjective
reliability, which is evaluated by the relationships in the communities.
The human relation diagram is a graph that shows the relationships between
entities in the community and shows the reliability of the partners in the transactions
(Shimizu et al.
2008
). For example, the relationships could be a friendship or a
business connection. This concept can be seen in the social network services. An
example of the diagram is shown in Fig.
