Abstract
Aspects of the present disclosure relate to identifying identical fields encrypted with different keys. A first field of a first data set is identified for encryption. A first hash value is generated for the first field. The first field is encrypted with a first encryption key to generate a first encrypted value. A second field of a second data set is identified for encryption. A second hash value is generated for the second field. The second field is encrypted with a second encryption key to generate a second encrypted value. The first hash value is compared to the second hash value, and in response to a determination that the first and second hash values are identical, the first and second data sets are associated. The association between the first and second data sets is stored.
