Socio-familiar Personalized Service and Its Application -- Towards a New Network Software for Next Generation Ubiquitous Service

摘要

Japan, along with many developed countries, is facing severe social problems caused by a declining birth rate. Gradual shrinkage of the working population has brought shortages of workers performing various services such as elderly care. Women are potential workers, but social assistance of working women remains insufficient. Social services such as elderly care and support for working women must be developed to address these problems. The infrastructure for future ubiquitous services must be designed as a service platform to provide those services respecting individual personal circumstances and at socially acceptable cost. Ubiquitous services provide enhanced mobility. Future ubiquitous services will evolve toward enhanced pervasiveness, and will be defined as advanced personalized services. This report presents a new concept, Socio-familiar Personalized Service (S-P Service), for future ubiquitous services based on sociality and humanity. Moreover, we propose a scalable distributed authentication method to realize S-P Service.
