Tuning product policy using observed evidence of customer behavior

摘要

A computer adapted for pay-as-you go or other metered use has a policy for determined what measurements to take to detect fraud as well as steps to take when fraud is found. To optimize between good performance and sufficient tests to reduce the risk of fraud, a policy is developed based on observation of the users behavior, using data taken at the computer, data from a payment processor or both. After analysis, an updated policy is securely loaded at the computer to determine what, and how often to measure for suspected fraud.

1. A server comprising:
at least one processing unit; and at least one computer-readable media storing computer-executable instructions which, when executed by the at least one processing unit, cause the server to:
acquire operational data reflecting operation of a computer;set policy information for the computer based on the acquired operational data; andsend the policy information from the server to the computer,wherein the policy information sent from the server to the computer causes the computer to impose a sanction on the computer for non-compliance with the policy information, andwherein the computer comprises a sanction circuit in a secure execution environment and the policy information directs the sanction circuit to impose the sanction.
