Abstract
A method of preventing a subject communication device 1021 . . . N from accessing a resource when it is determined to be counterfeit. The method involves delivering the web page component to a subject communication device 1021 . . . N in response to a request. The web page component is adapted to retrieve actual values of a plurality of attributes from the subject communication device 1021 . . . N. Reference values of the plurality of attributes are retrieved from a device property store 110 and the method determines that the subject communication device 1021 . . . N is counterfeit when at least one of the actual values of the plurality of attributes is different to the reference value of that attribute.
Claims25
Apparatus for preventing access to a resource, the apparatus comprising a processor and a memory storing instructions that, when executed by the processor, cause the processor to:
- receive a request from a subject communication device for access to the resource;
- cause transmission of computer executable code to the subject communication device, which computer executable code is arranged, when executed by the subject communication device, to retrieve from the subject communication device actual values of a plurality of attributes of the subject communication device and to transmit the actual values of the plurality of attributes to the apparatus;
- receive the actual values of the plurality of attributes from the subject communication device;
- retrieve from a device property store reference values of the plurality of attributes along with a confidence parameter for each of the reference values;
- determine a confidence score for the subject communication device by comparing the actual values to the reference values and selectively combining the confidence parameters based on the comparison;
- and
- prevent the subject communication device from accessing the resource based on the comparison and the confidence score.

Apparatus for determining that a subject communication device is counterfeit, the apparatus comprising a processor and a memory storing instructions that, when executed by the processor, cause the processor to:
- receive a request from the subject communication device for a web page component, the request including first identity information representing the identity of the subject communication device;
- receive second identity information representing the identity of the subject communication device;
- retrieve first reference values of a plurality of attributes from a device property store based on the first identity information;
- retrieve second reference values of the plurality of attributes from a device property store based on the second identity information;
- compare the first reference values of each of the plurality of attributes to the second reference values of each of the plurality of attributes respectively;
- and
- determine that the subject communication device is counterfeit when based on one or more of the first reference values of the plurality of attributes being different to the second reference value of that attribute.
