1. A method for associating identifiers, the method comprising:
obtaining, by a computing system comprising one or more processors,
one or more re-encrypted first data sets encrypted according to a first encryption key and re-encrypted according to a second encryption key, the one or more re-encrypted first data sets each comprising a first match key and a first identifier, and
one or more encrypted second data sets encrypted according to the second encryption key, the one or more encrypted second data sets each comprising a second match key and a second identifier;
generating, by the computing system, one or more re-encrypted second data sets by re-encrypting the one or more encrypted second data sets; and
assigning, by the computing system and based on matching relationships between first and second match keys of the one or more re-encrypted first data sets and the one or more re-encrypted second data sets, bridge identifiers linking first identifiers and second identifiers.
