Fraud prevention techniques

摘要

System, apparatus, computer program products and methods for preventing fraud attacks (e.g., on a virtual PBX service provider) are disclosed. In some implementations, a set of fraud evaluation processes are performed, an overall fraud evaluation score is incremented as each of the set of fraud evaluation processes are performed and a step result is obtained. A user request (e.g., account activation) can be denied or accepted based on the overall fraud evaluation score. In some implementations, the set of fraud evaluation processes can include one or more of: an internal fraud evaluation process, a process for checking multiple trial accounts associated with a common account parameter, a process for geolocation verification of multiple account parameters, a process for device type verification for a contact phone number, a process for credit card verification, and a process for placing a contact number verification call.

主权项

1. A method comprising:
receiving a service request from a remote communications device associated with a service account, wherein the service request identifies a contact phone number for the service account; validating the service request using one or more fraud evaluation processes, wherein the one or more fraud evaluation processes comprise a first fraud evaluation process, wherein validating the service request using the first fraud evaluation process comprises validating the contact phone number identified in the service request, and wherein validating the contact phone number identified in the service request comprises determining a count of other service accounts that are associated with the contact phone number; determining a respective score for each of the fraud evaluation processes, wherein determining a respective score for each of the fraud evaluation processes comprises determining a score for the first fraud evaluation process based at least in part on the count of other service accounts associated with the contact phone number; and evaluating the service request based on the respective scores.
