Exchange of Information and Values Taking Privacy into Consideration - IT Enabled Services - page 204

We propose a value exchange system with agents for smoother exchange of
information resources and services. When the transactions are done, the possibility
of the information leakage is detected through multiple communities, and the
balance between convenience, safety, and circulation is considered.
Outline of the whole system is described as follows.
1. The definition of the value
2. Settlement between two entities
3. The circulation of the value with securities. The credit of the securities is
evaluated by a human relationship diagram (Kubo et al. 2011 ).
4. The settlement based on the information capsule with agents.
12.7.2 The Exchange of Values
12.7.2.1 Values and Services
When information resources and services are supplied through a network, their
values are unified and expressed in prices in conventional settlements. Otherwise,
the supplier is either voluntarily giving them away or gaining advertisement
through sponsorship. Furthermore, although the price is in the local currency,
finding appropriate parties with which to exchange and the services for currency
can be difficult. It is also difficult to exchange one local currency for services in
different communities. Thus, various types of value should be considered to
describe a user's conditions for the transactions, and the information capsule with
the agent is required to exchange services between communities. Certain values,
e.g. laws, ethics, or feelings of satisfaction, are difficult to replace with the conven-
tional value of money. Additionally, resources that are operated independently and
are used among different services need to be used without the information leaking
or being falsified. Private information, e.g. personal information and transaction
history, should be distributed actively to supply adaptive services. In this situation,
privacy must be under the control of the subjects whose information this is.
12.7.2.2 The Implementation of the Scheme
The management of the traditional local currency is categorized into three types i.e.
the bill, the bankbook, and the account.
Our scheme adopts the bill method because we think it can best maintain the
privacy of the participants.
We proposed an electronic money system (Morizumi et al. 2010 ), a DRM system
based on the information capsule (Kinoshita and Morizumi 2008 ), and a securitiza-
tion system (Kinoshita et al. 2009 ).
We combined these systems to implement our local currency system.
