| Outline of Final Research Achievements |
In this research, we developed a big data processing middleware that enables the construction of systems that adapt to changing urgency levels by changing the degree of abstraction of the data and the degree of protection of the privacy according to the local degree of urgency determined automatically, as if you moved the magnifying glass up and down and left and right to look at the data. For this purpose, we established data abstraction level adjustment method and privacy protection degree adjustment method, constructed an architecture to switch these layers according to the level of urgency, integrated it as middleware with an interface that imitates the operation of the magnifying glass to handle the change of level of urgency, developed a big data application example, evaluated it experimentally, and published the results.
