I have recently written about real-time fraud detection solution from IBM based on SPSS and CICS.
Another solution from IBM in the fraud detection space has been recently highlighted by David Luckham in his site citing a Forbes article. This solution is based on the "Entity Analytics" solutions (specifically the Infosphere Identity Insights product. David Luckham comments "that are a lot of CEP under the hood of this stuff". This is true. After the acquisition of SRD by IBM, our team in IBM Haifa Research Lab helped integrating our work on Amit as embedded part in the Entity Analytics - (see the DEBS 2010 presentation by Ella Rabinovich on Industry Experience with Amit - slide 3). This integration seems to have survived all these years and being employed for useful purposes.
In any event, there are many solutions in which event processing is integrated with other technology to create specific solution, and we can see alliances between event processing technology and other technology in this area.
