Entity resolution between multiple private data sources

A system comprising:

• a memory;
• and
• a processor, the processor communicatively coupled to the memory, the processor configured to:
• receive, from a first client, a first request to perform an entity resolution operation, wherein the first request is related to a first record uploaded by the first client,
• wherein the first record has one or more first attributes, and wherein the first record is stored in a secure data store;
• transmit, the first request, to a first program split of a secure multi-party computation;
• and
• perform, by the first program split of the secure multi-party computation and by a third program split of the secure multi-party computation and based on the received request, an entity resolution operation related to the first record and one or more second records uploaded to the secure data store by a second client,
• wherein the third program split of the secure multi-party computation operates in the secure data store.

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions configured to:

• receive, from a first client, a first request to perform an entity resolution operation, wherein the first request is related to a first record uploaded by the first client,
• wherein the first record has one or more first attributes, and wherein the first record is stored in a secure data store;
• transmit, the first request, to a first program split of a secure multi-party computation;
• and
• perform, by the first program split of the secure multi-party computation and by a third program split of the secure multi-party computation and based on the received request, an entity resolution operation related to the first record and one or more second records uploaded to the secure data store by a second client,
• wherein the third program split of the secure multi-party computation operates in the secure data store.
