Secure Linkage Of Databases

摘要

A secure linkage between databases allows records of an individual in a first database to be linked to records of the same individual in a second database without disclosing or providing personal information outside of either database or system responsible for controlling access to the respective databases. As such, records of individuals may be securely linked together without compromising privacy or security of the databases.

1. A method for use in secure linkage of databases, the method comprising:
receiving a public encryption key generated by a key holder in conjunction with a corresponding private key; receiving an encrypted dataset of one or more fields of one or more records from a first data store, the encrypted dataset encrypted with the public encryption key generated by the key holder; generating encrypted comparison results between records of the received encrypted dataset and encrypted versions of one or more matching fields of records retrieved from a second data store, the encrypted versions encrypted using the public key; and sending the encrypted comparison results to the key holder of the private key corresponding to the public key for decryption.
