System and method for network-based fraud and authentication services

1. A method for providing identity protection services, comprising:

receiving at a validation server over a network a response from a credential associated with a user, the credential response provided by the user in order to authenticate the user to one of a plurality of sites on the network that accepts the credential as a factor for authentication;

verifying by the validation server the credential response on behalf of the one network site;

receiving at a fraud detection server over the network information in connection with a transaction associated with the user at the one network site; and

evaluating by the fraud detection server the transaction information for suspicious activity based at least in part on information provided to the fraud detection server in connection with one or more transactions at one or more sites on the network other than the one network site.

2. The method of claim 1 , wherein the validation server utilizes transaction information provided by the fraud detection server in connection with verifying the credential response provided by the user.

3. The method of claim 1 , wherein the fraud detection server utilizes verification information provided by the validation server in connection with evaluating the user's transaction information for suspicious activity.

4. The method of claim 1 , wherein the fraud detection server evaluates the transaction information for suspicious activity based at least in part on other information not provided to the fraud detection server in connection with the one or more transactions at the one or more sites on the network other than the one network site.

5. The method of claim 4 , wherein the other information is queried from a database associated with the DNS infrastructure of the Internet.

6. The method of claim 5 , wherein the other information includes IP geolocation data.

7. The method of claim 1 , wherein the step of evaluating by the fraud detection server further comprises:

performing a primary fraud check; and

upon determining that the transaction is not suspicious at the primary fraud check, providing to said network site an indication that the transaction is not suspicious.

8. The method of claim 1 , wherein the step of evaluating by the fraud detection server further comprises:

performing a primary fraud check; and

upon determining that the transaction is suspicious at the primary fraud check, performing a secondary fraud check.

9. The method of claim 8 , wherein said secondary fraud check comprises requesting confirmation of a user identity using at least one or more of a telephone, email, or SMS confirmation.

10. The method of claim 1 , further comprising:

determining at the fraud detection server that the transaction is fraudulent;

providing to the network site an indication that the transaction is fraudulent; and

receiving, at the fraud detection server, from the network site, identifying information for the fraudulent transaction.

11. The method of claim 10 , further comprising:

compiling information associated with a plurality of transactions associated with a particular user;

determining transaction tendencies for the particular user based upon the plurality of transactions;

subsequent to the plurality of transactions, receiving a new transaction associated with said particular user; and

determining that the new transaction is fraudulent based at least in part on a comparison between the transaction tendencies and the new transaction.

12. A system for providing identity protection services, comprising:

a validation server configured to provide an authentication service;

a fraud detection server configured to provide a fraud detection service;

an authentication database communicatively linked to the validation server; and

a fraud detection database communicatively linked to the fraud detection server, wherein

the validation server receives over a network a response from a credential associated with a user, the credential response provided by the user in order to authenticate the user to one of a plurality of sites on the network that accepts the credential as a factor for authentication,

the validation server verifies the credential response on behalf of the one network site,

the fraud detection server receives over the network information in connection with a transaction associated with the user at the one network site, an

the fraud detection server evaluates the transaction information for suspicious activity based at least in part on information provided to the fraud detection server in connection with one or more transactions at one or more sites on the network other than the one network site.

13. The system of claim 12 , wherein the validation server utilizes transaction information provided by the fraud detection server in connection with verifying the credential response provided by the user.

14. The system of claim 12 , wherein the fraud detection server utilizes verification information provided by the validation server in connection with evaluating the user's transaction information for suspicious activity.

15. The system of claim 12 , wherein the fraud detection server evaluates the transaction information for suspicious activity based at least in part on other information not provided to the fraud detection server in connection with the one or more transactions at the one or more sites on the network other than the one network site.

16. The system of claim 15 , wherein the other information is queried from a database associated with the DNS infrastructure of the Internet.

17. The system of claim 16 , wherein the other information includes IP geolocation data.
