FACILITATING ENTITY RESOLUTION VIA SECURE ENTITY RESOLUTION DATABASE

In some aspects, an entity-resolution computing system for entity resolution is provided. The entity-resolution computing system includes an entity resolution computing device configured as an interface between a client computing device and an encrypted identity data repository that contain resolved entity dataset. The entity resolution computing device is configured for servicing a resolution request from the client computing device by matching encrypted indexes generated from identity data objects stored in a client identity database to encrypted data objects stored in the encrypted identity data repository. The resolution computing device retrieves and transmits a common entity identifier associated with the encrypted data objects so that the client computing device can link the identity data objects stored in a client identity database via the common entity identifier.
