Authorization methods and systems for accessing multiple data sources

A data management device comprising:

• a processor in communication with a non-transitory, tangible storage medium storing instructions that are executed by the processor to perform operations comprising:
• aggregating data from a plurality of data sources into an aggregated data set, wherein each of the data sources is associated with an access rule set comprising an entity identifier and a corresponding access permission to access a data record available from a corresponding data source of the plurality of data sources;
• receiving, from a requesting device, a request to access the aggregated data set, the request comprising an identifier associated with the requesting device;
• determining, based on the identifier associated with the requesting device, the requesting device is denied access to at least one of the plurality of data sources providing data to the aggregated data set;
• determining, based on a transformed access control list, the requesting device is allowed access to the aggregated data set;
• and
• providing the aggregated data set to the requesting device.

A system for managing a plurality of data sources, the system comprising:

• at least one processor;
• and
• memory storing computer-readable instructions that, when executed by the at least one processor, cause the at least one processor to:
• receive, from a requesting device, a request to access an aggregated data set comprising data from at least two of the plurality of data sources, the request comprising an identifier associated with the requesting device;
• and
• transmit the aggregated data set to the requesting device when an access rule set associated with one of the at least two of the plurality of data sources comprises a rule denying access to the requesting device to the one of the at least two of the plurality of data sources.
