Abstract

Polymorphic encryption is described in a way to restrict access and enhance security of a secure data access system. In one example, a data vault has a first copy of a value being encrypted according to a first encryption scheme to enable a first operation on the first copy when the first copy is encrypted without decrypting the first copy and a second copy being encrypted according to a second encryption scheme. A governance layer has at least a first policy configured to enable the first operation, the governance layer configured to permit the first operation for an authenticated user. An interface layer has roles supporting a selected policy, the interface layer further comprising a user interface to receive user credentials, to link the credentials to a role and to send an authentication of the user and the role to the governance layer.
