RECEIVING NODE, DATA MANAGEMENT SYSTEM, DATA MANAGEMENT METHOD AND STRAGE MEDIUM

摘要

Disclosed is a technique that satisfies both the dispersion performance of the data storage locations and the access efficiency in data acquisition, even when handling a wide variety of sensor data. A receiving node determines, upon receipt of a data storage request or a data acquisition request, a data server in which data is to be stored. The receiving node includes key generation unit which generates a new key using a specified data key and a masked time-of-day acquired by applying a mask to a specified time-of-day, and destination node calculation unit which determines the data server in which the data is to be stored, using the new key generated by the key generation unit.

1. A receiving node that determines, upon receipt of a data storage request or a data acquisition request, a data server in which data is to be stored, the receiving node comprising circuitry configured to:
key generation means which generate a new key using a specified data key and a masked time-of-day acquired by applying a mask to a specified time-of-day; and destination node calculation means which determine the data server in which the data is to be stored, using the new key generated by the key generation.
