Abstract

An credential verification service (CVS) authenticates digital credentials, such as, digital certificates, at the request of online service providers. The CVS stores the authentication results and transaction information in a central activity log. The transaction information can include a size of the transaction, the online service requesting the authentication, an internet protocol (IP) address of a computing device originating the transaction and the goods or services involved in the transaction. The CVS generates an activity report from the activity log that lists the authentication results and the transaction information. A fraud detection module within the CVS analyzes the activity log to identify any unusual patterns in order to identify fraudulent activities or general misuse of the digital credential.

Claims

1. A method comprising:

receiving, over a data transmission network, use information describing a first use of a digital credential by an owner of a digital credential, at any of a plurality of different services where the digital credential can be used, the digital credential being a digital security mechanism associated with a the owner'"'"'s identity;

receiving use information describing a second use of the digital credential by a delegate of the owner of the digital credential, at any of the plurality of different services where the digital credential can be used;

storing the use information in an activity log;

generating an activity report for the delegate based on the activity log;

generating an activity report for the owner based on the activity log;

allowing said owner to view all reports; and

allowing said delegate to view only the activity report for the delegate and not the activity report for the owner or activity reports for other delegates.

2. The method of claim 1, wherein the use information includes transaction information.

3. The method of claim 1, wherein the use information includes verification information for the digital credential.

4. The method of claim 2, wherein the transaction information includes at least one of a message that was signed, a transaction value, an online service, an internet protocol (IP) address, a value of the transaction, a date of the transaction and a the time of the transaction.

5. The method of claim 1, wherein the digital credential includes a digital signature key, and further wherein generating the activity report includes associating a name to the digital signature key and listing the name of the digital signature key.

6. The method of claim 1, wherein generating the activity report for the owner includes generating the activity report upon request by an owner of the digital credential.

7. The method of claim 1, wherein generating the activity report includes generating the activity report each time the digital credential is verified.

8. The method of claim 1, wherein generating the activity report includes generating a report periodically.

9. The method of claim 1 further including analyzing the activity log to detect misuse of the digital credential.

10. The method of claim 6, wherein generating the activity report includes listing activity for a plurality of digital signature keys associated with the owner.

11. The method of claim 1 further comprising:

authorizing one or more delegates to use a delegated digital credential to act on behalf of the owner of the digital credential for specified functions, wherein verifying the use of the digital credential includes determining whether the delegated digital credential was authorized for the specific use.

12. The method of claim 1, wherein generating the activity report for the owner includes generating activity reports of the delegates of the owner.

13. A method comprising:

receiving, over a data transmission network, transaction requests from a plurality of delegate users who are delegated from an owner, wherein the transaction requests include digital credentials for the delegate users, the digital credentials being digital security mechanisms associated with users'"'"' identities;

processing the transaction requests; and

communicating transaction information to a central service, wherein the transaction information includes the digital credentials of the delegates, the transaction information communicated to create, for the plurality of delegate users, activity reports regarding the usage of the digital credentials, the activity reports created at the central service that said owner is allowed to view while each delegate is allowed to view only their own activity report and not allowed to view reports for other delegates.

14. The method of claim 13, wherein processing the transaction requests includes communicating the digital credentials to the central service for verification.

15. The method of claim 13, wherein processing a requested transaction includes:

verifying the digital credential; and

communicating a result of the verification to the credential service.

16. The method of claim 13 further includes receiving an activity report from the central service, wherein the activity report lists the transaction information for each digital credential.

17. The method of claim 13, wherein the transaction information includes at least one of a message that was signed, a transaction value, an online service, an internet protocol (IP) address, a value of the transaction, a date of the transaction and a the time of the transaction.

18. An article comprising a machine-readable medium storing instructions operable to cause one or more machines to perform operations comprising:

receiving, over a data transmission network, use information describing a first use of a digital credential by an owner of a digital credential, at any of a plurality of different services where the digital credential can be used, the digital credential being a digital security mechanism associated with the owner'"'"'s identity;

receiving use information describing a second use of the digital credential by a delegate of the owner of the digital credential, at any of the plurality of different services where the digital credential can be used;

storing the use information in an activity log;

generating an activity report for the delegate based on the activity log;

generating an activity report for the owner based on the activity log;

allowing said owner to view all reports; and

allowing said delegate to view only the activity report for the delegate and not the activity report for the owner or activity reports for other delegates.

19. The article of claim 18, wherein the use information includes transaction information.

20. The article of claim 18, wherein the use information includes verification information for the digital credential.
