Title:
HOMOMORPHIC INFERENCE DEVICE, HOMOMORPHIC INFERENCE METHOD, HOMOMORPHIC INFERENCE PROGRAM, AND ANONYMIZED INFORMATION PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/102624
Kind Code:
A1
Abstract:
A range assessment part (412) receives the input of an input encrypted text Ci obtained by encrypting input data, assesses whether a value obtained from the input data falls within a reference range, and generates a range encrypted text aj based on the result of the assessment. A result generation part (413) generates a result encrypted text D corresponding to the result of carrying out, on the input data, inference including a non-polynomial computation by carrying out a homomorphic computation on the range encrypted text aj generated by the range assessment part (412). An output part (414) outputs the result encrypted text D.
