Latest Patents

Johnson’s listed patent, “Web Application Execution with Limited Data Access and Extended Display,” describes a system that determines an application’s permitted access to an ontology containing object types and link types instantiated from underlying datasets. The access scope depends on the user account running the application and excludes operations that would write changes back to those datasets.

The system continuously supplies a limited-scope token with a future expiration date to represent the current access scope. The application uses the token as a cookie, and the system evaluates each web request containing that cookie to allow access within the represented scope. The application can generate a graphical webpage in kiosk mode.
