In some aspects, an entity-resolution computing system for entity resolution is provided. The entity-resolution computing system includes an entity-resolution server configured for correlating data objects from an identity data repository that contains account or transaction data for entities based on the data objects including a common portion of the account or transaction data. The entity-resolution server updates the identity data repository to include an entity identifier that links the data objects and indicates that the data objects refer to a common entity. The entity-resolution server creates an entity-resolution data structure having the data objects with the entity identifier and a new variant data object containing a modified version of account or transaction data that match the common entity. The entity-resolution server encrypts the entity-resolution data structure and causes the encrypted entity-resolution data structure to be transmitted to a client computing system for use in augmenting client data.

Facilitating entity resolution, keying, and search match without transmitting personally identifiable information in the clear

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.
