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

Search indexes can be automatically generated and used for expediting searching of a computerized database. For example, a system can access an inquiry dataset that includes relationships between prior inquiries and returned records from a database. The system can then generate a set of Boolean indexes based on the prior inquiries. The system can then identify frequent indexes that occur at least a threshold number of times in the set of Boolean indexes and that have estimated candidate sizes that are less than a threshold size. The system can then select the frequent index with the highest frequency from among the frequent indexes. The selected frequent index can be subsequently used to expedite searching of the database in response to receiving a search query associated with the frequent index from a client device.

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.
