SYSTEMS AND METHODS FOR USE IN DATA COUPLING AMONG DATA STRUCTURES

Systems and methods are provided for coupling data structures in different domains to provide cross-domain data access. One example computer- implemented method includes receiving, from a requestor, an access request including a case type and an indicator of a domain and determining a restriction associated with the domain. The method also includes compiling a first message key specific to the access request and transmitting the first message key to the requestor. The method further includes receiving an information request including a second message key and a query specific to a person, verifying the second message key based on the first message key, and coupling to a data structure in the domain. The method then includes, in response to verifying the second message key, submitting the query from the information request to the coupled data structure and providing a response to the query, from the data structure, to the requestor.
