Various embodiments are provided for performing weighted partial matching under homomorphic encryption in a computing environment. Selected data may be encoded and encrypted into an encrypted query for comparison using private set intersection (PSI) under homomorphic encryption (HE). An encrypted score may be determined according to data blocks of the selected data and a set of weights for each of the data blocks of the selected data to identify matches between the data and the encrypted query. The encrypted score may be decrypted and decoded to identify matches between the encrypted query with the selected data.

Abstract

Various embodiments are provided for performing weighted partial matching under homomorphic encryption in a computing environment. Selected data may be encoded and encrypted into an encrypted query for comparison using private set intersection (PSI) under homomorphic encryption (HE). An encrypted score may be determined according to data blocks of the selected data and a set of weights for each of the data blocks of the selected data to identify matches between the data and the encrypted query. The encrypted score may be decrypted and decoded to identify matches between the encrypted query with the selected data.
