Smart Society Using Decentralized PDS

Rich personal data is necessary to improve the quality of services to the data-subject individuals, but such data has been mostly controlled by business operators and public organizations, preventing optimal utilization of the data. As such data shall be electronically disclosed to the data-subject individuals due to public regulations (GDPR in particular) and relevant commercial business models, however, each individual shall be able to accumulate, share and utilize their own data primarily for the sake of themselves. Personal data controlled by data-subject individuals is also easy to collect and use, based on their consent, for the sake of R&D, policymaking, and so forth. PDS (Personal Data Store) is a software tool to allow individuals to manage and utilize their own data along these lines. PLR (Personal Life Repository) is a sort of PDS which is decentralized in the sense that nobody mediates data sharing between the data subjects and the data users. This decentralization eliminates the cost for centralized mediation and the associated risk of leaking all the sharable data, so that PLR is an extremely low-cost, secure, and GDPR-compliant means for raising the value of personal services, which account for most of GDP in most countries.
