ABSTRACT:
Sensitive data associations for related data values are protected. A set of related data values is received. The set of related data values include at least a first data value and a second data value. The first data value is associated with a first data field and the second data value is associated to a second data field. First encrypted data is created by encrypting the first data value using a first encryption key and a second encrypted data is created by encrypting the second data value using a second encryption key. The first data value is stored in a first data table, the second data value is stored in a second data table, the first encrypted data is stored in the second table, and the second encrypted data is stored in the first table.
