Abstract
<p>Centralized management of personal data means that the manager is in charge of many people’s personal data, so that this big data can be utilized or leak at one time. On the other hand, decentralized management of personal data means that each individual or her agent manages her own data only, so that the data utilized or leaking at one time is just part of her own data, entailing much higher security. PDS (personal data store) is a mechanism to allow each individual to electronically accumulate and utilize her own data by sharing the data with others. Individuals can use their own data so as to improve their own benefits, hence improving the whole social value of B2C services. PDS is either centralized or decentralized, and decentralized PDSs are much more secure and convenient. Decentralized PDSs are either server oriented or personal-device oriented. PLR (personal life repository) is a personal-device oriented, decentralized PDS, whose introduction and operation costs are very low because it uses commodities for both personal devices and servers. The spread of such decentralized PDSs will be triggered by the increasing needs for secure and low-cost management and utilization of personal data in line with to marketing, liberalization of power retailing, My Number, super high vision broadcasting, reform of medical system, and so on.</p>
