Abstract
Disclosed herein is a method including identifying a first key seed for an external key; generating a second key seed from a first instance of first data from a first source; computing a mapping function between the first key seed and the second key seed, where the mapping function is stored and the first key seed and second key seed are discarded; generating a third key seed from a second instance of second data from a second source; applying the mapping function to the third key seed to generate a fourth key seed; and regenerating the external key using the fourth key seed.
