Fraud monitoring system with distributed cache
First Claim
1. A system comprising:
- a first server located at a first locale and routing a first series of purchase transaction requests for a payment service;
a second server located at a second locale and routing a second series of purchase transaction requests for said payment service;
a central database that is remote from said first and second locales and stores transaction data of said first and second series of purchase transaction requests;
a distributed cache that is connected to said central database and stores and synchronizes a set of transaction details across said first and second locales, rather than at said central database; and
a risk service operating at said first locale and having access to said set of transaction details from said distributed cache at said first locale without accessing said central database;
wherein said risk service generates a fraud warning based on a result of a comparison of at least one transaction detail in said set of transaction details and at least one transaction detail of a new purchase transaction request received at said first server.

Abstract
Systems and methods for fraud monitoring in a payment service are disclosed. An exemplary system includes a first server being located at a first locale and routing a first series of transaction requests. The system includes a second server being located at a second locale and routing a second series of transaction requests. The transactions requests may or may not be associated with a single payment service user account. The system includes a distributed cache storing a set of transaction details of the two series of transaction requests. The system includes a risk service having access to the set of transaction details from the distributed cache. The risk service generates a fraud warning based on a result of a comparison of at least one transaction detail in the set of transaction details and at least one transaction detail of a new transaction request received by the first server.

11. A computer-implemented process comprising:
-
processing a first series of purchase transaction requests at a first server; processing a second series of purchase transaction requests at a second server; storing transaction data concerning transactions associated with said first and said second series of purchase transaction requests in a central database; storing historical transaction information in a distributed cache, rather than in the central database, the distributed cache being connected to said central database; receiving a purchase transaction request; conducting a comparison of information regarding said purchase transaction request with said historical transaction information by accessing said distributed cache without accessing said central database; and issuing a fraud warning based on results of said comparison; wherein said first and said second series of purchase transaction requests are associated with a single user account; wherein said first and second servers are in different locales; wherein said distributed cache is at said different locales and synchronizes the historical transaction information across the different locales, rather than in the central database; and wherein said central database is remote from said different locales. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
