Data aggregation system for enabling query operations on restricted data that originates from multiple independent multiple sources

1. A computer system comprising:

a memory to store:

a set of run time instructions;

a collection of records, wherein each record in the collection of records is structured to include a set of multiple fields of which at least some fields are individually assigned a field value, and each field value includes a source identifier of the field value, the source identifier corresponding to a source of a plurality of sources which collectively supply field values for the collection of records; and

a library of data usage rules including a set of usage rules for each source of the plurality of sources; and

one or more processors that execute instructions from the set of run time instructions to:

process requests from multiple computing entities, each request being for one or more unknown field values that are associated with a known field value specified in that request;

for each request, (i) search the collection of records to determine a first matching record that includes the known field value of that request; (ii) determine, from the first matching record, a first field value that correlates to at least one of the unknown field values; (iii) identify, from data associated with the first field value, at least one source from the plurality of sources which is an origin of the first field value; (iv) determine, based at least in part on the at least one identified source, one or more usage rules from the library of data usage rules that pertain to the first field value; and (v) provide a response to the request that is in accordance with the determined one or more usage rules; and

when multiple sources are identified as the origin of the first field value of the first matching record for a first given request, select, by the one or more processors, the determined one or more usage rules as being relevant usage rules of a first source of the multiple sources, to exclusion of one or more relevant usage rules of each of the other sources of the multiple sources, based on a credibility ranking of the sources.

2. The computer system of claim 1 , wherein the one or more processors select the determined one or more usage rules as being relevant usage rules of the first source of the multiple sources, to exclusion of one or more relevant usage rules of each of the other sources of the multiple sources, further based on an objective of minimizing a number of unknown field values of the request that are provided no corresponding field values in the response from the first matching record.

3. The computer system of claim 1 , wherein a first record of the collection of records includes at least one field value including a source identifier corresponding to a first source of the plurality of sources, and wherein a second record of the collection of records includes at least one field value including a source identifier corresponding to a second source of the plurality of sources.

4. The computer system of claim 1 , wherein each record in the collection of records is encoded using a numerical transformation or substitution.

5. The computer system of claim 1 , wherein the known field value specified in the request comprises personal identifiable information about an individual.

6. The computer system of claim 5 , wherein the personal identifiable information comprises a phone number, email address, residence, social security number, or legal name of the individual.

7. The computer system of claim 1 , wherein the multiple computing entities are remote from the computer system.

8. The computer system of claim 1 , wherein the one or more usage rules limit the response to a binary response.

9. A computer-implemented method for implementing a data aggregation system, the method comprising:

processing, by the data aggregation system, requests from multiple computing entities, each request being for one or more unknown field values that are associated with a known field value specified in that request; and

for each request,

(i) searching, by the data aggregation system, a collection of records to determine a first matching record that includes the known field value of that request, wherein each record in the collection of records is structured to include a set of multiple fields of which at least some fields are individually assigned a field value, and each field value includes a source identifier of the field value, the source identifier corresponding to a source of a plurality of sources which collectively supply field values for the collection of records;

(ii) determining, by the data aggregation system, from the first matching record, a first field value that correlates to at least one of the unknown field values;

(iii) identifying, by the data aggregation system, from data associated with the first field value, multiple sources from the plurality of sources that are an origin of the first field value;

(iv) determining, by the data aggregation system, one or more usage rules from a library of usage rules that pertain to the first field value, the one or more usage rules being relevant usage rules of a first source of the multiple sources, to exclusion of one or more relevant usage rules of each of the other sources of the multiple sources, based on a credibility ranking of the sources; and

(v) providing, by the data aggregation system, a response to the request that is in accordance with the determined one or more usage rules.

10. The computer-implemented method of claim 9 , wherein a first record of the collection of records includes at least one field value including a source identifier corresponding to a first source of the plurality of sources, and wherein a second record of the collection of records includes at least one field value including a source identifier corresponding to a second source of the plurality of sources.

11. The computer-implemented method of claim 9 , wherein the determining the one or more usage rules comprises determining the one or more usage rules as being relevant usage rules of the first source of the multiple sources, to exclusion of one or more relevant usage rules of each of the other sources of the multiple sources, further based on an objective of minimizing a number of unknown field values of the request that are provided no corresponding field values in the response from the first matching record.

12. The computer-implemented method of claim 9 , wherein each record in the collection of records is encoded using a numerical transformation or substitution.

13. The computer-implemented method of claim 9 , wherein the known field value specified in the request comprises personal identifiable information about an individual.

14. The computer-implemented method of claim 9 , wherein the multiple computing entities are remote from the computer system.

15. The computer-implemented method of claim 9 , wherein the one or more usage rules limit the response to a binary response.

16. A tangible, non-transitory computer-readable media storing computer-readable instructions that, when executed by one or more processors, cause the one or more processors to perform operations, the operations comprising:

processing requests from multiple computing entities, each request being for one or more unknown field values that are associated with a known field value specified in that request;

for each request,

(i) searching a collection of records to determine a first matching record that includes the known field value of that request, wherein each record in the collection of records is structured to include a set of multiple fields of which at least some fields are individually assigned a field value, and each field value includes a source identifier of the field value, the source identifier corresponding to a source of a plurality of sources which collectively supply field values for the collection of records;
