  • Visualized code review
    Patent number: 9594544
    Abstract: Visualization of the result of user interface code is provided in the context of code review. Changes to user interface code can be visualized to enable code reviewers to easily understand the effect of such changes.

  • Role-based access control modeling and auditing system
    Patent number: 9165156
    Abstract: A role-based access control (RBAC) modeling and auditing system is described that enables a user to access and/or create security roles that can be applied to users of a first software application. When a security role having a particular set of permissions has been accessed or created, the system can present a simulated user interface (UI) that indicates information that can be viewed and/or actions that can be performed by a user to whom the security role has been assigned when interacting with the first software application. The system may further provide “run as” functionality that enables a simulated UI to be generated for a particular user and that can display the security role(s) associated with the particular user. The system may be embodied in a second software application, such as a tool that is associated with the first software application.
