Title:
DECENTRALIZED DATA NON-SHARING ANALYZING SYSTEM, AND DECENTRALIZED DATA NON-SHARING ANALYZING METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2023135552
Kind Code:
A
Abstract:
To analyze the time up to occurrence of an event while a plurality of holders each neither share original data with others nor repeatedly communicate with others with respect to data decentralized and held by the plurality of holders.SOLUTION: In a decentralized data non-sharing analyzing system, the whole data set is decentralized and held by a plurality of holders, and a plurality of first analyzing devices output an anchor data intermediate representation and a partial data intermediate representation, a first label indicative of the time from the start to the end of an observation and a second label indicative of whether an event occurs to a second analyzing device. The second analyzing device analyzes the time up to the occurrence of an event based upon a data collaboration expression, the first label and the second label to generate an analysis result intermediate representation, and the plurality of first analyzing devices analyze partial test data respectively based upon data obtained by converting the analysis result intermediate representation with a first function.SELECTED DRAWING: Figure 6
