5.2.3 Fostering Trust Through the Reputation of an Open
Community
The appropriate style of the foundation of trust varies depending on the era, the size
of a population, and the social system of a nation.
A nation has the ability and will to bear the responsibility for the governance of
trust. In the first half of the twentieth century, most of the nations of the world
worked well as a foundation of trust for the governance. However, in the latter half
of twentieth century, many nations, including Japan, began to shrink and privatize
the functions of it. For example, in Japan from 1995 through 2009, the number of
civil servants had decreased by 894,000. By reducing the function of the nation, the
ability to accomplish trust through the nation has also been reduced.
Contrastingly, in recent years, giant enterprises of social web services like
Google, Facebook, Twitter, etc. have appeared. These giant enterprises have the
ability and will to bear a part of the responsibility of trust, to get new users, and to
have the users continue using their services. However, the trust that they provide is
minimum.
On the other hand, on social Web services, the users and their community have a
more powerful ability and strong will to bear the trust because they seriously need
it. Therefore, it is natural that we expect the foundation of fostering trust through
the reputation of an open community over the social web.
5.3 The Concept of Persona
Next, we describe the concept of a “persona,” which is another central concept in
this chapter. A persona is intended to symbolize the different side of the social role
of a person. A “pseudonym” is an identity of a person which can guarantee their
attributes while hiding their real name. A persona can also be used as a pseudonym
if it is used with an authentication infrastructure and with a well designed attribute
authorization system.
5.3.1 Persona and Privacy
A persona is useful for controlling the range of personal information. We are able to
bring together the attributes and behaviors of a person with an independent persona
which is a representation of a person's role in the workplace, in the family and in
their relationships with friends. By selecting the appropriate persona for the scene
we can control private information.
Some kinds of persona may be used for the exposure of illegal acts. Such kinds
of persona will be created and destroyed temporally by their owner.
