Abstract
A computer-implemented method is disclosed for handling sensitive data in a network comprising multiple security zones. The method includes sharing a data cleansing ruleset among a plurality of servers that are each within a respective security zone and using a multi-party cryptographic protocol that each of the plurality of servers participates in, to obtain a shared secret. Each server individually cleanses a respective dataset containing sensitive data using the data cleansing ruleset and then hashes the resulting cleansed dataset with a hash function using the shared secret as a salt. This produces a resultant dataset containing hashed representations of the original sensitive data, meaning that the dataset produced by each server can be collated to form a composite dataset without breaching data security requirements. A data operation can then be performed on the composite dataset.
