Resource access control system

Claim 1

The method of controlling access of a user to a resource, comprising: storing, in a control data base, a set of attributes concerning an access from an access demand source; maintaining a rules data base of rules concerning attributes for determining corrective action; determining whether data the control data base matches the rules in the rules data base; and effecting corrective action by disconnecting the access during access time in response to a match between data in the control data base and data in the rules data base.

Claim 7

A method as in any of claims 2-6, wherein said storage in sais first access data base includes storing one or more of the following attributes: requesting user request time length of use destination requested user authorization code whether use request is cellular.

Claim 8

A method as in any of the preceding claims, wherein the data in said rules data base includes access demands made: - During business hours, - During non-business hours, - Excessively long, - Domestic accesses, - To a limited dialed MPA = 800, - To a termination number = CPE, - To a country code, - ANI = CPE (Automatic Number Identification with Customer Premises Equipment), - Accesses using SDN-NRA (Software Defined Network - Network Remote Access), - To a suspected country code, - Using a bad ANI, - Of short duration, - Using repeated ANI, - From non-frequent accessor, - To successive different dialed numbers, Using suspected patterned dialing, - With a connect time difference using a less than PDD (Post Dialing Delay) +e, i.e. going from one number to another quickly, - Using an invalid authorization code, - With a number of accesses in repeat set greater than threshold, - Using a SDN (Software Defined Network) virtual private network, - Using different ANI to same termination No., - Using the same authorization code from another location greater than at least one access continuing, - Having greater than access duration overlap, - With simultaneous use of mobile number, - Cellular, - Of the same MIN, - Using distance between access locations/elapsed time greater than a given value τ, - Multiple accesses from same ANI (Automatic Number Identification) greater than x, - Repeated dialed numbers, - Terminating at a number which is a known DISA/RMATS (Direct Inward Switched Access/Remote Maintained Access Test System Maintained Port), - Originating in suspect MPA-NXX or pay-phone, - Multiple accesses from same ANI, - CPE (Customer Premise Equipment) to a known high fraud country, - CPE (Customer Premise Equipment) to a known medium fraud country, - Non CPE type of service, - Suspicious terminating number, - Multiple accesses billed to same number, - Multiple 800 accesses exceeding preset number.

Claim 9

A system controlling access of a user to a resource, comprising: a control data base with a set of attributes concerning an ongoing access from an access demand source; rules data base with rules concerning attributes for determining corrective action; means for determining whether data in the control data base matches the rules in the rules data base; and means for effecting corrective action by disconnecting the access during access time in response to a match between data in the control data base and data in the rules data base.

Claim 15

A system as in any of claims 10 to 14, wherein said storage in said first access data base includes storage for one or more of the following attributes: requesting user request time length of use destination requested user authorization code whether use request is cellular.

Claim 16

A system as in any of claims 9 to 15, wherein rules data base includes storage of access demands made: - During business hours, - During non-business hours, - Excessively long, - Domestic accesses, - To a limited dialed MPA = 800, - To a termination number = CPE, - To a country code, - ANI = CPE (Automatic Number Identification with Customer Premises Equipment), - Accesses using SDN-NRA (Software Defined Network - Network Remote Access), - To a suspected country code, - Using a bad ANI, - Of short duration, - Using repeated ANI, - From non-frequent accessor, - To successive different dialed numbers, Using suspected patterned dialing, - With a connect time difference using a less than PDD (Post Dialing Delay) +e, i.e. going from one number to another quickly, - Using an invalid authorization code, - With a number of accesses in repeat set greater than threshold, - Using a SDN (Software Defined Network) virtual private network, - Using different ANI to same termination No., - Using the same authorization code from another location greater than at least one access continuing, - Having greater than access duration overlap, - With simultaneous use of mobile number, - Cellular, - Of the same MIN, - Using distance between access locations/elapsed time greater than a given value τ, - Multiple accesses from same ANI (Automatic Number Identification) greater than x, - Repeated dialed numbers, - Terminating at a number which is a known DISA/RMATS (Direct Inward Switched Access/Remote Maintained Access Test System Maintained Port), - Originating in suspect MPA-NXX or pay-phone, - Multiple accesses from same ANI, - CPE (Customer Premise Equipment) to a known high fraud country, - CPE (Customer Premise Equipment) to a known medium fraud country, - Non CPE type of service, - Suspicious terminating number, - Multiple accesses billed to same number, - Multiple 800 accesses exceeding preset number.
