International Classification:

H04L 9/32

US Classification:

726 4

Abstract:

The subject disclosure relates to authorization based on a determination of permissions that can be granted for an action(s) to be performed on a resource. The determination of the permission is based on a set of rules that represent a theory including a notion of trust that has been divided into different sized tables. The tables are utilized to evaluate two or more input claims and to facilitate a determination of whether access to at least one system resource is to be granted. The evaluation can include matching the two or more input claims to rows in the table, wherein access is allowed if a match is found.

International Classification:

H04L 29/06

US Classification:

726 3

Abstract:

Methods and systems for verifying whether a user requesting an online account is likely a human or an automated program are described. A request for an online account may be received from a mobile device. A human challenge-response test adapted for displaying on a mobile device is displayed on the mobile device. Upon viewing the human challenge-response test, the user enters the user's solution to the human challenge-response test on the mobile device. A response hash value is created based on the user's solution. The response hash value is sent to an account request server for verification.
