Abstract
A method for linking de-identified data identifiers to traceable data identifiers in compliance with applicable data privacy rules and regulations includes: receiving a plurality of first data identifiers from a first computing system; applying a one-way hashing algorithm and salt to the first data identifiers to generate second data identifiers; storing an association between each of the first data identifiers and the respective second data identifier; receiving one or more specific second data identifiers from a second computing system; identifying, for each of the one or more specific second data identifiers, the associated first data identifier; and transmitting each identified associated first data identifier to the first computing system.
