Abstract

Systems and methods are provided for authorizing an electronic transaction. In one implementation at least one processor is programmed to receive electronic transaction data and historical transaction data, the electronic transaction data including an entity identifier component and an amount component of an electronic transaction; determine, based on the entity identifier component and the amount component, a location of the electronic transaction in a space of a distributed representation space, the distributed representation space comprising a mapping of electronic transaction components in a high-order space; determine locations of the historical transaction data in the distributed representation space; determine a decision boundary in the distributed representation space based on the locations of the historical transaction data; and authorize the electronic transaction based on the location of the electronic transaction being within the decision boundary.

First claim

What is claimed is:

1. An authorization system comprising:
at least one processor; and
at least one non-transitory computer readable medium containing instructions that when executed by the at least one processor cause the authorization system to perform operations comprising:
receiving electronic transaction data and historical transaction data, the electronic transaction data including an entity identifier component and an amount component of an electronic transaction;
determining, based on the entity identifier component and the amount component, a location of the electronic transaction in a distributed representation space, the distributed representation space comprising a mapping of electronic transaction components in a high-order space;
determining locations of the historical transaction data in the distributed representation space;
determining a decision boundary in the distributed representation space based on the locations of the historical transaction data; and
authorizing the electronic transaction based on the location of the electronic transaction being within the decision boundary.

2. The authorization system of claim 1 , wherein the operations further comprise:
determining a location of an additional electronic transaction in the distributed representation space; and
denying the additional electronic transaction based on the location of the additional electronic transaction being outside of the decision boundary.

3. The authorization system of claim 1 , wherein the historical transaction data is limited to electronic transactions including components satisfying one or more criteria.

4. The authorization system of claim 3 , wherein the one or more criteria includes electronic transactions associated with a specified merchant identifier.

5. The authorization system of claim 3 , wherein the one or more criteria includes electronic transactions associated with a specified customer identifier.

6. The authorization system of claim 3 , wherein the one or more criteria includes electronic transactions associated with transaction amounts exceeding a specified amount.

7. The authorization system of claim 1 , wherein the distributed representation space comprises first rows corresponding to entities and second rows corresponding to amount ranges.

8. The authorization system of claim 7 , wherein determining the location of the electronic transaction includes:
identifying rows of the distributed representation, the identified rows including a first row corresponding to a value of the entity identifier component and one of the second rows corresponding to a value of the amount component; and
determining the location of the electronic transaction as a linear combination of the identified rows.

9. The authorization system of claim 1 , wherein the electronic transaction data further includes at least one of an electronic transaction time component, a day of week component, a day of month component, and a day of year component.

10. The authorization system of claim 1 , wherein the operations further comprise determining a fraud score based on fraud criteria and the distributed representation space.

11. The authorization system of claim 10 , wherein the fraud criteria include at least one of:
a card not present indication,
a geographic location associated with the entity identifier, and
a predetermined category corresponding to the entity identifier.

12. A computer-implemented method for generating a distributed representation of electronic transaction data, comprising:
receiving electronic transaction data and historical transaction data, the electronic transaction data including an entity identifier component and an amount component of an electronic transaction;
determining, based on the entity identifier component and the amount component, a location of the electronic transaction in a distributed representation space, the distributed representation space comprising a mapping of electronic transaction components in a high-order space;
determining locations of the historical transaction data in the distributed representation space;
determining a decision boundary in the distributed representation space based on the locations of the historical transaction data; and
authorizing the electronic transaction based on the location of the electronic transaction being within the decision boundary.

13. The computer-implemented method of claim 12 , wherein the method further comprises:
determining a location of an additional electronic transaction in the distributed representation space; and
denying the additional electronic transaction based on the location of the additional electronic transaction being outside of the decision boundary.

14. The computer-implemented method of claim 12 , wherein the historical transaction data is limited to electronic transactions including components satisfying one or more criteria.

15. The computer-implemented method of claim 12 , wherein the distributed representation space comprises first rows corresponding to entities and second rows corresponding to amount ranges.

16. The computer-implemented method of claim 15 , wherein determining the location of the electronic transaction includes:
identifying rows of the distributed representation, the identified rows including a first row corresponding to a value of the entity identifier component and one of the second rows corresponding to a value of the amount component; and
determining the location of the electronic transaction as a linear combination of the identified rows.

17. The computer-implemented method of claim 12 , wherein the electronic transaction data further includes at least one of an electronic transaction time component, a day of week component, a day of month component, and a day of year component.

18. The computer-implemented method of claim 12 , wherein the method further comprises determining a fraud score based on fraud criteria and the distributed representation space.

19. The computer-implemented method of claim 18 , wherein the fraud criteria include at least one of:
a card not present indication,
a geographic location associated with the entity identifier, and
a predetermined category corresponding to the entity identifier.

20. A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, are configured to cause at least one processor to perform a method, the method comprising:
receiving electronic transaction data and historical transaction data, the electronic transaction data including an entity identifier component and an amount component of an electronic transaction;
determining, based on the entity identifier component and the amount component, a location of the electronic transaction in a distributed representation space, the distributed representation space comprising a mapping of electronic transaction components in a high-order space;
determining locations of the historical transaction data in the distributed representation space;
determining a decision boundary in the distributed representation space based on the locations of the historical transaction data; and
authorizing the electronic transaction based on the location of the electronic transaction being within the decision boundary.
