First Claim
Patent Images
1. A network security and fraud detection and prevention system, comprising:
- one or more network service providers that provides a service;
a network device that connects to at least one of the network service providers over a communications network to use the provided service; and
at least one network service provider further comprising a fraud detector comprising a clientwherein the client gathers information about the network device to generate a device identifier that identifies the network device, a database, and a module that receives the device identifier, stores the device identifier in the database and associates the device identifier with end-user account information provided by the network service provider and wherein the device identifier and end-user account information is shared between the one or more network service providers to detect fraud using the network device across the network service providers.

17. A method for detecting fraud during a connection of a network device to a network service provider using the fraud detection information from a plurality of associated network service providers, the method comprising:
-
validating a network device identifier assigned to the network device; validating a combination of the network device identifier and a network device fingerprint for the network device; verifying that the status of the network device identifier and the network device fingerprint for the network device are acceptable to the network service provider based on a set of status rules of the network service provider; and verifying that the status of the network device identifier and the network device fingerprint for the network device are acceptable to the associated network service providers. - View Dependent Claims (18)

19. A method for detecting fraud during a connection of an unknown network device to a network service provider, the method comprising:
-
launching an application on a network device that launches a fraud detection client; determining, using the client, that the network device is an unregistered network device; receiving a network device identifier requested from a fraud detection system;
generating, using the client, a fingerprint based on characteristics of the network device that is forwarded to the fraud detection system; andverifying, at the fraud detection system, that the fingerprint of the network device is not duplicative. - View Dependent Claims (20, 21)

22. A method for detecting fraud during a connection of a known network device to a network service provider, the method comprising:
-
launching an application on a network device that launches a fraud detection client on the network device; determining, using the client, that the network device is a registered network device having an assigned network device identifier; generating, using the client, a fingerprint based on characteristics of the network device that is forwarded to the fraud detection system with the assigned network device identifier; and verifying, at the fraud detection system, that the fingerprint of the network device is not duplicative and that the network device identifier is valid. - View Dependent Claims (23, 24)

25. A network security and fraud detection and prevention system, comprising:
-
one or more network service providers that provides a service; a network device that connects to at least one of the network service providers over a communications network to use the provided service; and at least one network service provider further comprising fraud detector means further comprising a client means, downloaded to the network device when the network device connects to the network service provider, for gathering information about the network device to generate a device identifier that identifies the network device, a database and means for receiving the device identifier, storing the device identifier in the database and associating the device identifier with end-user account information provided by the network service provider and wherein the device identifier and end-user account information is shared between the one or more network service providers to detect fraud using the network device across the network service providers. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A network security and fraud detection and prevention system, comprising:
-
one or more network service providers that provides a service; a network device that connects to at least one of the network service providers over a communications network to use the provided service; and at least one network service provider further comprising a fraud detector further comprising a client piece of code that is downloaded to the network device when the network device connects to the network service provider wherein the client gathers information about the network device to generate a device identifier that identifies the network device, a database and computer instructions that receive the device identifier and store the device identifier in the database and associate the device identifier with end-user account information provided by the network service provider and wherein the device identifier and end-user account information is shared between the one or more network service providers to detect fraud using the network device across the network service providers. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
