Method, system, and computer program product for detecting duplicate authorization requests
A method for detecting duplicate authorization requests includes: receiving an authorization request over an electronic payment processing network associated with an electronic payment transaction; determining whether the authorization request is a potential duplicate authorization request or is not a duplicate authorization request based on a bloom filter; in response to determining that the authorization request is a potential duplicate authorization request, determining a connectivity quality associated with the electronic payment processing network; and determining whether to process the authorization request based on the connectivity quality. A system and computer program product for detecting duplicate authorization requests are also disclosed.
1. A method for detecting duplicate authorization requests, comprising:
receiving, with at least one processor, an authorization request over an electronic payment processing network associated with an electronic payment transaction;
determining, with at least one processor, whether the authorization request is a potential duplicate authorization request or is not a duplicate authorization request based on a bloom filter;
in response to determining that the authorization request is a potential duplicate authorization request, determining, with at least one processor, a connectivity quality associated with the electronic payment processing network;
determining, with at least one processor, that the connectivity quality fails to satisfy a quality threshold; and
in response to determining that the connectivity quality fails to satisfy the quality threshold, determining, with at least one processor, the authorization request for processing.
2. The method of claim 1 , wherein the connectivity quality is based on at least one of the following: a network health score, a merchant system health score, a payment gateway system health score, an acquirer system health score, a transaction service provider system health score, an issuer system health score, or any combination thereof.
3. The method of claim 1 , wherein the connectivity quality is based on a response time within the electronic payment processing network.
4. The method of claim 1 , further comprising:
in response to determining that the authorization request is a potential duplicate authorization request, determining, with at least one processor, that the potential duplicate authorization request is an actual duplicate authorization request.
5. The method of claim 4 , wherein determining that the potential duplicate authorization request is an actual duplicate authorization request is based on a second filter.
6. The method of claim 4 , wherein determining that the potential authorization request is an actual duplicate authorization request comprises comparing a hash value associated with the authorization request with a hash value associated with a prior authorization request.
7. The method of claim 1 , further comprising:
determining, with at least one processor, a hash value associated with the authorization request,
wherein determining whether the authorization request is a potential duplicate authorization request comprises comparing the hash value associated with the authorization request with a hash value associated with a prior authorization request using the bloom filter.
8. The method of claim 1 , wherein determining that the connectivity quality fails to satisfy the quality threshold is based on connectivity rules provided by a merchant system.
9. The method of claim 1 , further comprising adjusting a sensitivity associated with the bloom filter based on the connectivity quality.
10. A system for detecting duplicate authorization requests, comprising at least one processor programmed or configured to:
receive an authorization request over an electronic payment processing network associated with an electronic payment transaction;
determine whether the authorization request is a potential duplicate authorization request or is not a duplicate authorization request based on a bloom filter;
in response to determining that the authorization request is a potential duplicate authorization request, determine a connectivity quality associated with the electronic payment processing network;
determine that the connectivity quality fails to satisfy a quality threshold; and
in response to determining that the connectivity quality fails to satisfy the quality threshold, submit the authorization request for processing.
11. The system of claim 10 , wherein the connectivity quality is based on at least one of the following: a network health score, a merchant system health score, a payment gateway system health score, an acquirer system health score, a transaction service provider system health score, an issuer system health score, or any combination thereof.
12. The system of claim 10 , wherein the connectivity quality is based on a response time within the electronic payment processing network.
13. The system of claim 10 , wherein the at least one processor is programmed or configured to:
in response to determining that the authorization request is a potential duplicate authorization request, determine that the potential duplicate authorization request is an actual duplicate authorization request.
14. The system of claim 13 , wherein determining that the potential duplicate authorization request is an actual duplicate authorization request is based on a second filter.
15. The system of claim 13 , wherein determining that the potential duplicate authorization request is an actual duplicate authorization request comprises comparing a hash value associated with the authorization request with a hash value associated with a prior authorization request.
16. The system of claim 10 , wherein the at least one processor is programmed or configured to:
determine a hash value associated with the authorization request,
wherein determining whether the authorization request is a potential duplicate authorization request comprises comparing the hash value associated with the authorization request with a hash value associated with a prior authorization request using the bloom filter.
17. The system of claim 10 , wherein determining whether to process the authorization request is based on connectivity rules provided by a merchant system.
18. The system of claim 10 , wherein the at least one processor is programmed or configured to adjust a sensitivity associated with the bloom filter based on the connectivity quality.
