Claim 10:
11. A computing system for device fingerprinting comprising:
a storage unit configured to store instructions;
a communication unit, coupled to the storage unit, configured to process the stored instructions to:
receive, at a first time and from an application, a first plurality of device attributes identifying a client device on which the application is being used, wherein the first plurality of device attributes comprises first device identification data and a total number of contacts in a first user's contact list;
receive, at a second time and from the application, an indication that a user is attempting to perform a transaction using the application on the client device;
transmit, in response to a receipt of the indication, a request for a second plurality of device attributes identifying the client device on which the application is being used, wherein the second plurality of device attributes is different than the first plurality of device attributes and comprises second device identification data and a total number of contacts in a second user's contact list; and
receive, in response to a transmission of the request for the second plurality of device attributes, the second plurality of device attributes; and

a control unit, coupled to the storage unit, configured to process the stored instructions to:
compare the second plurality of device attributes to the first plurality of device attributes; and
determine, based on a comparison of the second plurality of device attributes to the first plurality of device attributes, a device risk score indicating whether the user is authorized to perform the transaction using the application.
