SYSTEMS AND METHODS FOR SECURE PROVISIONING OF ACCESS TO TIERED DATABASES

Implementations are disclosed herein to provide tiered access to databases. In some implementations, a method includes an enrollment processor, generating, at the enrollment processor, an encryption key specific to a computing device associated with the tiered data; providing the encryption key to the computing device; receiving, at the enrollment processor, the tiered data that includes at least first tier data and second tier data, storing the tiered data, receiving, at the enrollment processor, an access request from a second computing device associated with a user, determining, using the in-memory cache, whether there is a match between the data elements and the stored second tier data, based on determination that there is the match, performing a decryption of a portion of the first tier data using the encryption key, and storing the decrypted portion of the first tier data in a third database connected to the enrollment processor.
