Abstract

Computer-implemented systems and methods are disclosed herein for use within secure multi-party computation. A system and method are used for storing an operation preference and a cryptographic preference. A data set is stored based on the operation preference and the cryptographic preference. A determination is made that processing the query involves performing an allowable operation on the data set based on the operation preference.

First claim

The invention claimed is:

1. A method for use within secure multi-party computation, comprising:
analyzing, by the one or more data processors, a query from a requestor associated with a data set comprising data provided by one or more data owners;
determining, by the one or more data processors, that processing the query involves performing an allowable operation on the data set based on an operation preference communicated by the one or more data owners;
determining, by the one or more data processors, one or more data elements of the data set required to perform the allowable operation on the data set;
selecting, by the one or more data processors, one or more encryption protocols based on a cryptographic preference specified by the one or more data owners for each of the one or more data elements of the data set; and
using, by the one or more data processors, the one or more encryption protocols to perform the allowable operation on the data set, with a summarized version of a transactional data analysis provided to the requestor while keeping the data from the one or more data owners private from one another.

2. The method of claim 1 , wherein the data set is stored at a centralized database warehouse having transactional data from multiple merchants and payment service providers.

3. The method of claim 1 , wherein the cryptographic preference is selected from a plurality of pre-defined cryptographic protocols.

4. The method of claim 1 , wherein the operation preference includes an allowed join operation.

5. The method of claim 1 , wherein the operation preference includes an allowed retrieval operation.

6. The method of claim 1 , wherein a two tiered system is used where methods which require large in-memory usage for each of the one or more data elements can use distributed files system and methods which require less in-memory usage use in-memory databases.

7. The method of claim 1 , further comprising:
storing, by the one or more data processors, the data set on an element by element basis according to the cryptographic preference.

8. A system for use within secure multi-party computation, comprising:
a memory; and
one or more processors disposed in communication with the memory and configured to issue processing instructions stored in the memory to:
analyze, by the one or more data processors, a query from a requestor associated with a data set comprising data provided by one or more data owners;
determine, by the one or more data processors, that processing the query involves performing an allowable operation on the data set based on an operation preference communicated by the one or more data owners;
select, by the one or more data processors, one or more encryption protocols based on a cryptographic preference specified by the one or more data owners for each of the data and the query; and
use, by the one or more data processors, the one or more encryption protocols to perform the allowable operation on the data set, with a summarized version of a transactional data analysis output encrypted according to the cryptographic preference corresponding to the data set provided to at least the requester while keeping the data from the one or more data owners private from one another.

9. The system of claim 8 , wherein a centralized database warehouse stores transactional data comprising the data set that is received from multiple merchants and payment service providers.

10. The system of claim 8 , wherein the cryptographic preference includes a plurality of encryption protocols prescribed for on individual elements of the data set.

11. The system of claim 8 , wherein the operation preference includes an allowed joint operation.

12. The system of claim 8 , wherein the operation preference includes an allowed retrieval operation.

13. The system of claim 8 , wherein a two tiered system is used where systems that require large in-memory usage for the data use distributed files system and systems that require less in-memory usage use in-memory databases.
